[GIT PULL] x86 platform drivers tree

[GIT PULL] x86 platform drivers tree

[Matthew Garrett]

Many of the x86 platform drivers are either entirely unrelated to ACPI, or
only barely so. So, with Len's blessing:

The following changes since commit baac35c4155a8aa826c70acee6553368ca5243a2:
  Xiaotian Feng (1):
        security: fix error return path in ima_inode_alloc

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/mjg59/platform-drivers-x86.git for_linus

Erik Andren (1):
      dell-laptop: Add another Dell laptop to the DMI whitelist

Mario Limonciello (4):
      compal-laptop: Add support for known Compal made Dell laptops
      compal-laptop: Replace sysfs support with rfkill support
      dell-laptop: Block software state changes when rfkill hard blocked
      dell-laptop: Blacklist machines not supporting dell-laptop

Matthew Garrett (7):
      MAINTAINERS: update drivers/platform/x86 information
      dell-laptop: Update rfkill state on kill switch
      dell-laptop: Fix platform device unregistration
      dell-laptop: Fix small memory leak
      dell-laptop: Pay attention to which devices the hardware switch controls
      hp-wmi: Add support for tablet rotation key
      toshiba_acpi: Add full hotkey support

Stuart Hayes (1):
      dell-laptop: Use buffer with 32-bit physical address

Thadeu Lima de Souza Cascardo (1):
      classmate-laptop: use a single MODULE_DEVICE_TABLE to get correct aliases

[PATCH 01/14] MAINTAINERS: update drivers/platform/x86 information

[Matthew Garrett]

Many of the drivers/platform/x86 drivers have nothing to do with ACPI, so
it's kind of inappropriate for them to be stuck under the ACPI mailing
list. Add a new mailing list (platform-driver-x86@vger.kernel.org) and,
with Len's blessing, add myself as subsystem maintainer.

By the way I noticed while registering on
http://vger.kernel.org/vger-lists.html#platform-driver-x86 that the list
does not have an archive yet.
Is it planned?

I have requested archival at gmane.org, which will also forward a request to
the www.mail-archive.com so it should start being archived on both these
places soon.

Ok,
Should I re-send the big asus-laptop series I sent to Len (not already
in acpi tree)
and send it back to you so it can be merged in platform-driver-x86 ?

It looks like Matthew didn't send this up, so I've appended it
to an asus branch in my tree (I had Roel Kluin's "remove duplicate 
comparison" patch sitting in there).

Matthew,
Unless you object, I'll send Corentin's asus-laptop cleanup
upstream with my treek.

thanks,

I've just pulled this in (along with a couple of other minor fixes) - 
I'm just waiting to make sure I get the right set of Thinkpad fixes 
before sending another pull request.

[PATCH 03/14] compal-laptop: Replace sysfs support with rfkill support

[Matthew Garrett]

From: Mario Limonciello <Mario_Limonciello@Dell.com>

This drops the support for manually groking the files in sysfs
to turn on and off the WLAN and BT for Compal laptops in favor
of platform rfkill support.

It has been combined into a single patch to not introduce regressions
in the process of simply adding rfkill support

[PATCH 04/14] dell-laptop: Update rfkill state on kill switch

[Matthew Garrett]

The rfkill interface on Dells only sends a notification that the switch
has been changed via the keyboard controller. Add a filter so we can
pick these notifications up and update the rfkill state appropriately.

Wrong order, you need to unregister filter first.

[PATCH 05/14] dell-laptop: Fix platform device unregistration

dell-laptop currently fails to clean up its platform device correctly.
Make sure that it's unregistered.

That should be platform_device_unregister(), otherwise you are missing

[PATCH 07/14] dell-laptop: Block software state changes when rfkill hard blocked

[Matthew Garrett]

From: Mario Limonciello <Mario_Limonciello@Dell.com>

The "hardware" switch is tied directly to a BIOS interface that will
connect and disconnect the hardware from the bus.

If you use the software interface to request the BIOS to make these
changes, the HW switch will be in an inconsistent state and LEDs may not
reflect the state of the HW.

[PATCH 09/14] dell-laptop: Use buffer with 32-bit physical address

[Matthew Garrett]

From: Stuart Hayes <stuart_hayes@dell.com>

Calls to communicate with system firmware via a SMI (using dcdbas)
need to use a buffer that has a physical address of 4GB or less.
Currently the dell-laptop driver does not guarantee this, and when the
buffer address is higher than 4GB, the address is truncated to 32 bits
and the SMI handler writes to the wrong memory address.

[PATCH 10/14] dell-laptop: Pay attention to which devices the hardware switch controls

[Matthew Garrett]

Right now, we assume that the hardware rfkill switch on Dells toggles all
radio devices. In fact, this can be configured in the BIOS and so right
now we may mark a device as hardware killed even when it isn't. Add code
to query the devices controlled by the switch, and use this when
determining the hardware kill state of a radio.

[PATCH 11/14] classmate-laptop: use a single MODULE_DEVICE_TABLE to get correct aliases

[Matthew Garrett]

From: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com>

Instead of a MODULE_DEVICE_TABLE for every acpi_driver ids table, we
create a table containing all ids to export to get a module alias for
each one.

This will fix automatic loading of the driver when one of the ACPI
devices is not present (like the accelerometer, which is not present in
some models).

[PATCH 14/14] toshiba_acpi: Add full hotkey support

Calling the ENAB method on Toshiba laptops results in notifications being

and sets up an input device if it's successful.

Re: [GIT PULL] x86 platform drivers tree

[Henrique de Moraes Holschuh]

I send yesterday a patchset (six patches) for thinkpad-acpi, which should
also go to stable.  Since it looks like you'll be thinkpad-acpi upstream,
will you pick them off linux-acpi and send them to Linus, or do you want me
to resend them to you?

Also, do you plan to use patchwork like we used to in linux-acpi?

Was triggered in -tip testing, caused by this upstream commit:

  116ee77: dell-laptop: Use buffer with 32-bit physical address

There's multiple buffer_mutex's in the kernel. Make this new one
static.

FYI, -tip testing found a (relatively rare) build failure introduced by these 
commits, which occurs with certain .config's - see the fix below. Please 
apply.

Thanks,

Subject: [PATCH] compal-laptop: Make it depend on CONFIG_RFKILL

-tip testing found this build failure (x86 randconfig):

 drivers/built-in.o: In function `setup_rfkill':
 compal-laptop.c:(.text+0x36abe8): undefined reference to `rfkill_alloc'
 compal-laptop.c:(.text+0x36abfc): undefined reference to `rfkill_register'
 compal-laptop.c:(.text+0x36ac30): undefined reference to `rfkill_alloc'
 compal-laptop.c:(.text+0x36ac44): undefined reference to `rfkill_register'

Which can happen with CONFIG_COMPAL_LAPTOP=y but COMPAL_LAPTOP=m.
