This patchset is the x86-specific part split from the generic part
of the zero-based patchset.
This patchset provides the following:
* x86_64: Fold pda into per cpu area
Declare the pda as a per cpu variable. This will move the pda
area to an address accessible by the x86_64 per cpu macros.
Subtraction of __per_cpu_start will make the offset based from
the beginning of the per cpu area. Since %gs is pointing to the
pda, it will then also point to the per cpu variables and can be
accessed thusly:
%gs:[&per_cpu_xxxx - __per_cpu_start]
* x86_64: Rebase per cpu variables to zero
Take advantage of the zero-based per cpu area provided above.
Then we can directly use the x86_32 percpu operations. x86_32
offsets %fs by __per_cpu_start. x86_64 has %gs pointing directly
to the pda and the per cpu area thereby allowing access to the
pda with the x86_64 pda operations and access to the per cpu
variables using x86_32 percpu operations. After rebasing
the access now becomes:
%gs:[&per_cpu_xxxx]
Introduces a new DEFINE_PER_CPU_FIRST to locate the percpu
variable (pda in this case) at the beginning of the percpu
.data section.
* x86_64: Cleanup non-smp usage of cpu maps
Cleanup references to the early cpu maps for the non-SMP configuration
and remove some functions called for SMP configurations only.

* Declare the pda as a per cpu variable. This will move the pda area
to an address accessible by the x86_64 per cpu macros. Subtraction
of __per_cpu_start will make the offset based from the beginning
of the per cpu area. Since %gs is pointing to the pda, it will
then also point to the per cpu variables and can be accessed thusly:
%gs:[&per_cpu_xxxx - __per_cpu_start]
* The boot_pdas are only needed in head64.c so move the declaration
over there. And since the boot_cpu_pda is only used during
bootup and then copied to the per_cpu areas during init, it is
then removable. In addition, the initial cpu_pda pointer table
is reallocated to be the correct size for the number of cpus.
* Remove the code that allocates special pda data structures.
Since the percpu area is currently maintained for all possible
cpus then the pda regions will stay intact in case cpus are
hotplugged off and then back on.
* Relocate the x86_64 percpu variables to begin at zero. Then
we can directly use the x86_32 percpu operations. x86_32
offsets %fs by __per_cpu_start. x86_64 has %gs pointing
directly to the pda and the per cpu area thereby allowing
access to the pda with the x86_64 pda operations and access
to the per cpu variables using x86_32 percpu operations.
* This also supports further integration of x86_32/64.

thanks Mike, applied them to x86.git. Do these depend on the generic
bits? (for now we'll keep these in -testing, so that they do not reach
-mm)

randconfig QA on x86.git found a crash on x86.git#testing with
nmi_watchdog=2 (config attached) - and i bisected it down to this patch.
config and crashlog attached. You can pick up x86.git#testing via:
http://people.redhat.com/mingo/x86.git/README
(since i had to hand-merge the patch when integrating it, i've attached
the merged version below.)

Subject: x86_64: Fold pda into per cpu area v3
From: Mike Travis <travis@sgi.com>
Date: Tue, 19 Feb 2008 12:33:36 -0800
* Declare the pda as a per cpu variable. This will move the pda area
to an address accessible by the x86_64 per cpu macros. Subtraction
of __per_cpu_start will make the offset based from the beginning
of the per cpu area. Since %gs is pointing to the pda, it will
then also point to the per cpu variables and can be accessed thusly:
%gs:[&per_cpu_xxxx - __per_cpu_start]
* The boot_pdas are only needed in head64.c so move the declaration
over there. And since the boot_cpu_pda is only used during
bootup and then copied to the per_cpu areas during init, it is
then removable. In addition, the initial cpu_pda pointer table
is reallocated to be the correct size for the number of cpus.
* Remove the code that allocates special pda data structures.
Since the percpu area is currently maintained for all possible
cpus then the pda regions will stay intact in case cpus are
hotplugged off and then back on.
* Relocate the x86_64 percpu variables to begin at zero. Then
we can directly use the x86_32 percpu operations. x86_32
offsets %fs by __per_cpu_start. x86_64 has %gs pointing
directly to the pda and the per cpu area thereby allowing
access to the pda with the x86_64 pda operations and access
to the per cpu variables using x86_32 percpu operations.
* This also supports further integration of x86_32/64.

You might want to apply this patch.
I also wonder if _cpu_pda should be set only at the very end of
x86_64_cleanup_pda(), after array initialization, or maybe other
cpus are not yet running ? (Sorry I cannot boot test this patch at this momeent)
[PATCH] x86_64: x86_64_cleanup_pda() should use nr_cpu_ids instead of NR_CPUS
We allocate an array of nr_cpu_ids pointers, so we should respect its bonds.
Delay change of _cpu_pda after array initialization.
Also take into account that alloc_bootmem_low() :
- calls panic() if not enough memory
- already clears allocated memory

Umm, yes, the generic part provides the groundwork for the x86 part.

Yes, thank you! I had changed this in a later version ... I must have grabbed
an earlier version to do the patch split. (But I did not have the memory barrier.)
At this point only the boot cpu is running and we're in the time slot between
allocating per cpu areas and sched_init().
I'm just building an x86.git#testing branch. I will see if I can't replicate
the problem.
Thanks again,
Mike

I must need some different test machines as my AMD box does not fail with
either yours or Thomas's configs, and the Intel box complains about the
PCI-e e1000 driver and dies. I'll see about configuring a new box.
Did you try Eric's patch to see if that fixed the failure?
Thanks,
Mike

This just happened again with the patches dropped, so it is a separate bug -
just another regression.
I now recall that it has been happening on every fifth-odd boot for a few
weeks now. The machine prints
Time: tsc clocksource has been installed
then five instances of "system 00:01: iomem range 0x...", then it hangs.
ie: it never prints "system 00:01: iomem range 0xfe600000-0xfe6fffff has
been reserved" from http://userweb.kernel.org/~akpm/dmesg-akpm2.txt.
It may have some correlation with whether the machine was booted via
poweron versus `reboot -f', dunno.

the tsc thing seems to be an accidental proximity to me.
such a hard hang has a basic system setup feel to it: the PCI changes in
2.6.25 or perhaps some ACPI changes. But it could also be timer related
(although in that case it typically doesnt hang in the middle of a
system setup sequence)
i'd say pci=nommconf, but your dmesg has this:
PCI: Not using MMCONFIG.
but, what does seem to be new in your dmesg (i happen to have a historic
dmesg-akpm2.txt of yours saved away) is:
hpet0: at MMIO 0xfed00000, IRQs 2, 8, 11
hpet0: 3 64-bit timers, 14318180 Hz
was hpet active on this box before? Try hpet=disable perhaps - does that
change anything? (But ... this is still a 10% chance suggestion, there's
way too many other possibilities for such bugs to occur.)

Thanks Andrew for catching this, I'll take a look. Our "big box amd" system still has
a failing serial port, so I haven't been able to remotely test on it.

I dunno - the machine does this rarely and today seems to be the day on
which it likes to produce its long-occurring doesnt-reboot-at-all problem,
which is different, and might be a BIOS thing.
Now current mainline is giving me this:
zsh: exec format error: /opt/crosstool/gcc-4.0.2-glibc-2.3.6/x86_64-unknown-linux-gnu/bin/x86_64-unknown-linux-gnu-gcc
and /usr/bin/sum matches that binary on a different machine.
I think I'll go home and knit a sweater or something.
