From: Denis 'GNUtoo' Carikli <GNUtoo@no-log.org>

commit b2ccf065f7b23147ed135a41b01d05a332ca6b7e upstream.

The neo1973 driver had wrong codec name which prevented the "sound card"
from appearing.

[ 02/41] ALSA: hda/realtek - Apply the coef-setup only to ALC269VB

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kailang Yang <kailang@realtek.com>

commit 526af6eb4dc71302f59806e2ccac7793963a7fe0 upstream.

The coef setup in alc269_fill_coef() was designed only for ALC269VB
model, and this has some bad effects for other ALC269 variants, such
as turning off the external mic input.  Apply it only to ALC269VB.

[ 03/41] aio: fix io_setup/io_destroy race

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@ZenIV.linux.org.uk>

commit 86b62a2cb4fc09037bbce2959d2992962396fd7f upstream.

Have ioctx_alloc() return an extra reference, so that caller would drop it
on success and not bother with re-grabbing it on failure exit.  The current
code is obviously broken - io_destroy() from another thread that managed
to guess the address io_setup() would've returned would free ioctx right
under us; gets especially interesting if aio_context_t * we pass to
io_setup() points to PROT_READ mapping, so put_user() fails and we end
up doing io_destroy() on kioctx another thread has just got freed...

[ 04/41] aio: fix the "too late munmap()" race

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@ZenIV.linux.org.uk>

commit c7b285550544c22bc005ec20978472c9ac7138c6 upstream.

Current code has put_ioctx() called asynchronously from aio_fput_routine();
that's done *after* we have killed the request that used to pin ioctx,
so there's nothing to stop io_destroy() waiting in wait_for_all_aios()
from progressing.  As the result, we can end up with async call of
put_ioctx() being the last one and possibly happening during exit_mmap()
or elf_core_dump(), neither of which expects stray munmap() being done
to them...

We do need to prevent _freeing_ ioctx until aio_fput_routine() is done
with that, but that's all we care about - neither io_destroy() nor
exit_aio() will progress past wait_for_all_aios() until aio_fput_routine()
does really_put_req(), so the ioctx teardown won't be done until then
and we don't care about the contents of ioctx past that point.

Since actual freeing of these suckers is RCU-delayed, we don't need to
bump ioctx refcount when request goes into list for async removal.
All we need is rcu_read_lock held just over the ->ctx_lock-protected
area in aio_fput_routine().

[ 05/41] x86: Derandom delay_tsc for 64 bit

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@linutronix.de>

commit a7f4255f906f60f72e00aad2fb000939449ff32e upstream.

Commit f0fbf0abc093 ("x86: integrate delay functions") converted
delay_tsc() into a random delay generator for 64 bit.  The reason is
that it merged the mostly identical versions of delay_32.c and
delay_64.c.  Though the subtle difference of the result was:

 static void delay_tsc(unsigned long loops)
 {
-	unsigned bclock, now;
+	unsigned long bclock, now;

Now the function uses rdtscl() which returns the lower 32bit of the
TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64
bit this fails when the lower 32bit are close to wrap around when
bclock is read, because the following check

       if ((now - bclock) >= loops)
       	  	break;

evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0
because the unsigned long (now - bclock) of these values results in
0xffffffff00000001 which is definitely larger than the loops
value. That explains Tvortkos observation:

"Because I am seeing udelay(500) (_occasionally_) being short, and
 that by delaying for some duration between 0us (yep) and 491us."

Make those variables explicitely u32 again, so this works for both 32
and 64 bit.

[ 06/41] PCI: ignore pre-1.1 ASPM quirking when ASPM is disabled

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Matthew Garrett <mjg@redhat.com>

commit 4949be16822e92a18ea0cc1616319926628092ee upstream.

Right now we won't touch ASPM state if ASPM is disabled, except in the case
where we find a device that appears to be too old to reliably support ASPM.
Right now we'll clear it in that case, which is almost certainly the wrong
thing to do. The easiest way around this is just to disable the blacklisting
when ASPM is disabled.

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

commit bd0f2e6da7ea9e225cb2dbd3229e25584b0e9538 upstream.

The HS/VS interrupt handler needs to access the pipeline object. It
erronously tries to get it from the CCDC output video node, which isn't
necessarily included in the pipeline. This leads to a NULL pointer
dereference.

Fix the bug by getting the pipeline object from the CCDC subdev entity.

[ 08/41] rt2x00: fix random stalls

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislaw Gruszka <sgruszka@redhat.com>

commit 3780d038fdf4b5ef26ead10b0604ab1f46dd9510 upstream.

Is possible that we stop queue and then do not wake up it again,
especially when packets are transmitted fast. That can be easily
reproduced with modified tx queue entry_num to some small value e.g. 16.

If mac80211 already hold local->queue_stop_reason_lock, then we can wait
on that lock in both rt2x00queue_pause_queue() and
rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock
is possible that __ieee80211_wake_queue() will be performed before
__ieee80211_stop_queue(), hence we stop queue and newer wake up it
again.

Another race condition is possible when between rt2x00queue_threshold()
check and rt2x00queue_pause_queue() we will process all pending tx
buffers on different cpu. This might happen if for example interrupt
will be triggered on cpu performing rt2x00mac_tx().

To prevent race conditions serialize pause/unpause by queue->tx_lock.

[ 11/41] vfs: fix return value from do_last()

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Miklos Szeredi <mszeredi@suse.cz>

commit 7f6c7e62fcc123e6bd9206da99a2163fe3facc31 upstream.

complete_walk() returns either ECHILD or ESTALE.  do_last() turns this into
ECHILD unconditionally.  If not in RCU mode, this error will reach userspace
which is complete nonsense.

[ 13/41] acer-wmi: No wifi rfkill on Lenovo machines

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ike Panhc <ike.pan@canonical.com>

commit 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a upstream.

We have several reports which says acer-wmi is loaded on ideapads
and register rfkill for wifi which can not be unblocked.

Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.

Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no
wifi rfkill capability, there are reports which says acer-wmi also
block wireless on Thinkpad E520/E420.

[ 14/41] atl1c: dont use highprio tx queue

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Eric Dumazet <eric.dumazet@gmail.com>

[ Upstream commit 11aad99af6ef629ff3b05d1c9f0936589b204316 ]

This driver attempts to use two TX rings but lacks proper support :

1) IRQ handler only takes care of TX completion on first TX ring
2) the stop/start logic uses the legacy functions (for non multiqueue
drivers)

This means all packets witk skb mark set to 1 are sent through high
queue but are never cleaned and queue eventualy fills and block the
device, triggering the infamous "NETDEV WATCHDOG" message.

Lets use a single TX ring to fix the problem, this driver is not a real
multiqueue one yet.

Minimal fix for stable kernels.

[ 15/41] neighbour: Fixed race condition at tbl->nht

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Michel Machado <michel@digirati.com.br>

[ Upstream commit 84338a6c9dbb6ff3de4749864020f8f25d86fc81 ]

When the fixed race condition happens:

1. While function neigh_periodic_work scans the neighbor hash table
pointed by field tbl->nht, it unlocks and locks tbl->lock between
buckets in order to call cond_resched.

2. Assume that function neigh_periodic_work calls cond_resched, that is,
the lock tbl->lock is available, and function neigh_hash_grow runs.

3. Once function neigh_hash_grow finishes, and RCU calls
neigh_hash_free_rcu, the original struct neigh_hash_table that function
neigh_periodic_work was using doesn't exist anymore.

4. Once back at neigh_periodic_work, whenever the old struct
neigh_hash_table is accessed, things can go badly.

[ 17/41] ppp: fix ppp_mp_reconstruct bad seq errors

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Ben McKeegan <ben@netservers.co.uk>

[ Upstream commit 8a49ad6e89feb5015e77ce6efeb2678947117e20 ]

This patch fixes a (mostly cosmetic) bug introduced by the patch
'ppp: Use SKB queue abstraction interfaces in fragment processing'
found here: http://www.spinics.net/lists/netdev/msg153312.html

The above patch rewrote and moved the code responsible for cleaning
up discarded fragments but the new code does not catch every case
where this is necessary.  This results in some discarded fragments
remaining in the queue, and triggering a 'bad seq' error on the
subsequent call to ppp_mp_reconstruct.  Fragments are discarded
whenever other fragments of the same frame have been lost.
This can generate a lot of unwanted and misleading log messages.

This patch also adds additional detail to the debug logging to
make it clearer which fragments were lost and which other fragments
were discarded as a result of losses. (Run pppd with 'kdebug 1'
option to enable debug logging.)

[ 18/41] sfc: Fix assignment of ip_summed for pre-allocated skbs

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Ben Hutchings <bhutchings@solarflare.com>

[ Upstream commit ff3bc1e7527504a93710535611b2f812f3bb89bf ]

When pre-allocating skbs for received packets, we set ip_summed =
CHECKSUM_UNNCESSARY.  We used to change it back to CHECKSUM_NONE when
the received packet had an incorrect checksum or unhandled protocol.

Commit bc8acf2c8c3e43fcc192762a9f964b3e9a17748b ('drivers/net: avoid
some skb->ip_summed initializations') mistakenly replaced the latter
assignment with a DEBUG-only assertion that ip_summed ==
CHECKSUM_NONE.  This assertion is always false, but it seems no-one
has exercised this code path in a DEBUG build.

Fix this by moving our assignment of CHECKSUM_UNNECESSARY into
efx_rx_packet_gro().

[ 19/41] tcp: fix false reordering signal in tcp_shifted_skb

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Neal Cardwell <ncardwell@google.com>

[ Upstream commit 4c90d3b30334833450ccbb02f452d4972a3c3c3f ]

When tcp_shifted_skb() shifts bytes from the skb that is currently
pointed to by 'highest_sack' then the increment of
TCP_SKB_CB(skb)->seq implicitly advances tcp_highest_sack_seq(). This
implicit advancement, combined with the recent fix to pass the correct
SACKed range into tcp_sacktag_one(), caused tcp_sacktag_one() to think
that the newly SACKed range was before the tcp_highest_sack_seq(),
leading to a call to tcp_update_reordering() with a degree of
reordering matching the size of the newly SACKed range (typically just
1 packet, which is a NOP, but potentially larger).

This commit fixes this by simply calling tcp_sacktag_one() before the
TCP_SKB_CB(skb)->seq advancement that can advance our notion of the
highest SACKed sequence.

Correspondingly, we can simplify the code a little now that
tcp_shifted_skb() should update the lost_cnt_hint in all cases where
skb == tp->lost_skb_hint.

From: Neal Cardwell <ncardwell@google.com>

[ Upstream commit c0638c247f559e1a16ee79e54df14bca2cb679ea ]

In tcp_mark_head_lost() we should not attempt to fragment a SACKed skb
to mark the first portion as lost. This is for two primary reasons:

(1) tcp_shifted_skb() coalesces adjacent regions of SACKed skbs. When
doing this, it preserves the sum of their packet counts in order to
reflect the real-world dynamics on the wire. But given that skbs can
have remainders that do not align to MSS boundaries, this packet count
preservation means that for SACKed skbs there is not necessarily a
direct linear relationship between tcp_skb_pcount(skb) and
skb->len. Thus tcp_mark_head_lost()'s previous attempts to fragment
off and mark as lost a prefix of length (packets - oldcnt)*mss from
SACKed skbs were leading to occasional failures of the WARN_ON(len >
skb->len) in tcp_fragment() (which used to be a BUG_ON(); see the
recent "crash in tcp_fragment" thread on netdev).

(2) there is no real point in fragmenting off part of a SACKed skb and
calling tcp_skb_mark_lost() on it, since tcp_skb_mark_lost() is a NOP
for SACKed skbs.

[ 25/41] tcp: fix tcp_shift_skb_data() to not shift SACKed data below snd_una

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Neal Cardwell <ncardwell@google.com>

[ Upstream commit 4648dc97af9d496218a05353b0e442b3dfa6aaab ]

This commit fixes tcp_shift_skb_data() so that it does not shift
SACKed data below snd_una.

This fixes an issue whose symptoms exactly match reports showing
tp->sacked_out going negative since 3.3.0-rc4 (see "WARNING: at
net/ipv4/tcp_input.c:3418" thread on netdev).

Since 2008 (832d11c5cd076abc0aa1eaf7be96c81d1a59ce41)
tcp_shift_skb_data() had been shifting SACKed ranges that were below
snd_una. It checked that the *end* of the skb it was about to shift
from was above snd_una, but did not check that the end of the actual
shifted range was above snd_una; this commit adds that check.

Shifting SACKed ranges below snd_una is problematic because for such
ranges tcp_sacktag_one() short-circuits: it does not declare anything
as SACKed and does not increase sacked_out.

Before the fixes in commits cc9a672ee522d4805495b98680f4a3db5d0a0af9
and daef52bab1fd26e24e8e9578f8fb33ba1d0cb412, shifting SACKed ranges
below snd_una happened to work because tcp_shifted_skb() was always
(incorrectly) passing in to tcp_sacktag_one() an skb whose end_seq
tcp_shift_skb_data() had already guaranteed was beyond snd_una. Hence
tcp_sacktag_one() never short-circuited and always increased
tp->sacked_out in this case.

After those two fixes, my testing has verified that shifting SACKed
ranges below snd_una could cause tp->sacked_out to go negative with
the following sequence of events:

(1) tcp_shift_skb_data() sees an skb whose end_seq is beyond snd_una,
    then shifts a prefix of that skb that is below snd_una

(2) tcp_shifted_skb() increments the packet count of the
    already-SACKed prev sk_buff

(3) tcp_sacktag_one() sees the end of the new SACKed range is below
    snd_una, so it short-circuits and doesn't increase tp->sacked_out

(5) tcp_clean_rtx_queue() sees the SACKed skb has been ACKed,
    decrements tp->sacked_out by this "inflated" pcount that was
    missing a matching increase in tp->sacked_out, and hence
    tp->sacked_out underflows to a u32 like 0xFFFFFFFF, which casted
    to s32 is negative.

(6) this leads to the warnings seen in the recent "WARNING: at
    net/ipv4/tcp_input.c:3418" thread on the netdev list; e.g.:
    tcp_input.c:3418  WARN_ON((int)tp->sacked_out < 0);

More generally, I think this bug can be tickled in some cases where
two or more ACKs from the receiver are lost and then a DSACK arrives
that is immediately above an existing SACKed skb in the write queue.

This fix changes tcp_shift_skb_data() to abort this sequence at step
(1) in the scenario above by noticing that the bytes are below snd_una
and not shifting them.

[ 29/41] block: Fix NULL pointer dereference in sd_revalidate_disk

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jun'ichi Nomura <j-nomura@ce.jp.nec.com>

commit fe316bf2d5847bc5dd975668671a7b1067603bc7 upstream.

Since 2.6.39 (1196f8b), when a driver returns -ENOMEDIUM for open(),
__blkdev_get() calls rescan_partitions() to remove
in-kernel partition structures and raise KOBJ_CHANGE uevent.

However it ends up calling driver's revalidate_disk without open
and could cause oops.

In the case of SCSI:

  process A                  process B
  ----------------------------------------------
  sys_open
    __blkdev_get
      sd_open
        returns -ENOMEDIUM
                             scsi_remove_device
                               <scsi_device torn down>
      rescan_partitions

          <oops>
Oopses are reported here:
http://marc.info/?l=linux-scsi&m=132388619710052

This patch separates the partition invalidation from rescan_partitions()
and use it for -ENOMEDIUM case.

commit 9f53d2fe815b4011ff930a7b6db98385d45faa68 upstream.

The following situation might occur:

__blkdev_get:			add_disk:

				register_disk()
get_gendisk()

disk_block_events()
	disk->ev == NULL

				disk_add_events()

__disk_unblock_events()
	disk->ev != NULL
	--ev->block

Then we unblock events, when they are suppose to be blocked. This can
trigger events related block/genhd.c warnings, but also can crash in
sd_check_events() or other places.

I'm able to reproduce crashes with the following scripts (with
connected usb dongle as sdb disk).

<snip>
DEV=/dev/sdb
ENABLE=/sys/bus/usb/devices/1-2/bConfigurationValue

function stop_me()
{
	for i in `jobs -p` ; do kill $i 2> /dev/null ; done
	exit
}

trap stop_me SIGHUP SIGINT SIGTERM

for ((i = 0; i < 10; i++)) ; do
	while true; do fdisk -l $DEV  2>&1 > /dev/null ; done &
done

while true ; do
echo 1 > $ENABLE
sleep 1
echo 0 > $ENABLE
done
</snip>

I use the script to verify patch fixing oops in sd_revalidate_disk
http://marc.info/?l=linux-scsi&m=132935572512352&w=2
Without Jun'ichi Nomura patch titled "Fix NULL pointer dereference in
sd_revalidate_disk" or this one, script easily crash kernel within
a few seconds. With both patches applied I do not observe crash.
Unfortunately after some time (dozen of minutes), script will hung in:

[ 1563.906432]  [<c08354f5>] schedule_timeout_uninterruptible+0x15/0x20

[ 1563.906490]  [<f7f03203>] usb_stor_disconnect+0x13/0x20 [usb_storage]

Anyway I think this patch is some step forward.

As drawback, I do not teardown on sysfs file create error, because I do
not know how to nullify disk->ev (since it can be used). However add_disk
error handling practically does not exist too, and things will work
without this sysfs file, except events will not be exported to user
space.

[ 32/41] Block: use a freezable workqueue for disk-event polling

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alan Stern <stern@rowland.harvard.edu>

commit 62d3c5439c534b0e6c653fc63e6d8c67be3a57b1 upstream.

This patch (as1519) fixes a bug in the block layer's disk-events
polling.  The polling is done by a work routine queued on the
system_nrt_wq workqueue.  Since that workqueue isn't freezable, the
polling continues even in the middle of a system sleep transition.

Obviously, polling a suspended drive for media changes and such isn't
a good thing to do; in the case of USB mass-storage devices it can
lead to real problems requiring device resets and even re-enumeration.

The patch fixes things by creating a new system-wide, non-reentrant,
freezable workqueue and using it for disk-events polling.

[ 33/41] sparc32: Add -Av8 to assembler command line.

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "David S. Miller" <davem@davemloft.net>

commit e0adb9902fb338a9fe634c3c2a3e474075c733ba upstream.

Newer version of binutils are more strict about specifying the
correct options to enable certain classes of instructions.

The sparc32 build is done for v7 in order to support sun4c systems
which lack hardware integer multiply and divide instructions.

So we have to pass -Av8 when building the assembler routines that
use these instructions and get patched into the kernel when we find
out that we have a v8 capable cpu.

[ 37/41] rapidio/tsi721: fix bug in register offset definitions

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexandre Bounine <alexandre.bounine@idt.com>

commit 9bbad7da76b3dd578fb55c862624366a8c9ccd22 upstream.

Fix indexed register offset definitions that use decimal (wrong) instead
of hexadecimal (correct) notation for indexing multipliers.

Incorrect definitions do not affect Tsi721 driver in its current default
configuration because it uses only IDB queue 0.  Loss of inbound
doorbell functionality should be observed if queue other than 0 is used.

[ 38/41] i2c-algo-bit: Fix spurious SCL timeouts under heavy load

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ville Syrjala <syrjala@sci.fi>

commit 8ee161ce5e0cfc689eb677f227a6248191165fac upstream.

When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.

To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.

[ 39/41] iscsi-target: Fix reservation conflict -EBUSY response handling bug

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Bellinger <nab@linux-iscsi.org>

commit 00fdc6bbef77844ce397a7de7acfaf25e8e2e4eb upstream.

This patch addresses a iscsi-target specific bug related to reservation conflict
handling in iscsit_handle_scsi_cmd() that has been causing reservation conflicts
to complete and not fail as expected due to incorrect errno checking.  The problem
occured with the change to return -EBUSY from transport_generic_cmd_sequencer() ->
transport_generic_allocate_tasks() failures, that broke iscsit_handle_scsi_cmd()
checking for -EINVAL in order to invoke a non GOOD status response.

This was manifesting itself as data corruption with legacy SPC-2 reservations,
but also effects iscsi-target LUNs with SPC-3 persistent reservations.

This bug was originally introduced in lio-core commit:

[ 40/41] target: Fix compatible reservation handling (CRH=1) with legacy RESERVE/RELEASE

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Bellinger <nab@linux-iscsi.org>

commit 087a03b3ea1c8d6e2d5743a8d1c6d571058caa04 upstream.

This patch addresses a bug with target_check_scsi2_reservation_conflict()
return checking in target_scsi2_reservation_[reserve,release]() that was
preventing CRH=1 operation from silently succeeding in the two special
cases defined by SPC-3, and not failing with reservation conflict status
when dealing with legacy RESERVE/RELEASE + active SPC-3 PR logic.

Also explictly set cmd->scsi_status = SAM_STAT_RESERVATION_CONFLICT during
the early non reservation holder failure from pr_ops->t10_seq_non_holder()
check in transport_generic_cmd_sequencer() for fabrics that already expect
it to be set.

This bug was originally introduced in mainline commit:

commit eacac00ce5bfde8086cd0615fb53c986f7f970fe

From: Guenter Roeck <guenter.roeck@ericsson.com>

commit fecfb64422d91a9621a3f96ab75c3a5f13e80b58 upstream.

Intersil reports that all chips supported by the zl6100 driver require
an interval between chip accesses, even ZL2004 and ZL6105 which were thought
to be safe.

[...]

If I understand the logic correctly, el == &locks_to_send means we
already used all the lock_to_push structures.  (It should also be
equivalent to testing i == count.  Why is i incremented but not
otherwise used in the loop?)

But we test this before flock->fl_flags & FL_POSIX, which means we
don't know whether this lock actually needs to be assigned one of
those structures.  So it appears that we might report a spurious error
if the lock list ends with a mandatory lock.  If so, this is
relatively harmless but does need to be fixed.

Ben.

This has already been merged into Linus's tree, so you need to submit a
patch to apply on top of it.

What do you mean by "fixed version"?

> cifs_push_posix_locks

What do you mean by this?

If there was a follow-on patch in Linus's tree that fixes a problem, I
need that git commit id, not a "fixed" patch that does not match up with
what is in Linus's tree right now.

So, if that's the case, please let me know what the git commit id of
that patch is please.

thanks,

Ok, seems I didn't understand this process correctly. I reposted the
new "fixed" version of this patch, because I thought it is more
suitable for stale to merge one correct patch rather than one
incorrect + follow-on fixup. Sorry if I was wrong.

I need to stay identical with Linus's tree as much as possible, it's
easier for everyone in the end that way for tracking exactly what
happens.

 Sorry for the late response, but I bought a new machine this week
(low-end i3) and this has bitten me.  I prepared a "generic" x86_64
kernel using 3.2.9, which I hoped would be good enough to get me
started, and later prepared another using 3.3.0.  Long story short -
3.2.9 was adequate, 3.3.0 crashes early in boot (before switching
from the 80x25 console to kms).  All the interesting part has
scrolled off the screen, and it's too early to get logged.

 By a process of elimination, I found that all the stable kernels
after 3.2.11 crash.  Looking at the changes there, a few seemed
possible candidates.  With those all added to 3.2.8, that too crashed
(I had other things that needed tweaking in the config, indeed I
still do, and wanted to try to fix some of them which is why I went
back to an older kernel, trying not to set EXTRAVERSION
unnecessarily).  I then took that amended config to use for newer
kernels.  Trial and error showed this commit seemed to be the
problem.

 I then reverted this commit from 3.3.0, and took my amended .config
which works adequately in vanilla 3.2.8.  I'm now running that.

Yes, good. I guess I should just take it and not wait for Bjorn, since

quite yet.
