2013-10-15T22:31:47+00:00

Commit 1696d9d (ACPI: Remove the old /proc/acpi/event interface)
left /proc/acpi/event in the ACPI_BUTTON help in Kconfig, so
remove it from there.

Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

2013-09-05T16:31:03+00:00

Pull i2c updates from Wolfram Sang:
 "Highlights:

   - OF and ACPI helpers are now included in the core, and not in
     external files anymore.  This removes dependency problems for
     modules and is cleaner, in general.
   - mv64xxx-driver gains fifo usage to support mv78230
   - imx-driver overhaul to support VF610
   - various cleanups, most notably related to devm_* and CONFIG_PM
     usage
   - driver bugfixes and smaller feature additions"

i2c: move ACPI helpers into the core

2013-08-23T08:22:29+00:00

This follows what has already been done for the DeviceTree helpers. Move
the ACPI helpers from drivers/acpi/acpi_i2c.c to the I2C core and update
documentation accordingly.

This also solves a problem reported by Jerry Snitselaar that we can't build
the ACPI I2C helpers as a module.

ACPI: Remove the old /proc/acpi/event interface

2013-07-15T11:56:36+00:00

It is quite some time that this one has been deprecated.
Get rid of it.

Should some really important user be overseen, it may be reverted and
the userspace program worked on first, but it is time to do something
to get rid of this old stuff...

ACPI: remove "config ACPI_DEBUG_FUNC_TRACE"

2013-04-08T12:05:41+00:00

Kconfig symbol ACPI_DEBUG_FUNC_TRACE was only used (through its
corresponding macro) in drivers/acpi/acpica/acmacros.h. That macro
was removed from that header in v3.8, with commit
86ff0e508f88eda6e479a897476026055831d2d8 ("ACPICA: Fix unmerged
acmacros.h divergences."), so ACPI_DEBUG_FUNC_TRACE can now be
removed too, as it is unused.

ACPI / BGRT: Don't let users configure BGRT on non X86 systems

2013-04-03T11:17:20+00:00

Fengguang Wu's 0-Day kernel build testing backend found the
following build error for an allmodconfig build on ia64:

   drivers/built-in.o: In function `show_yoffset':
>> bgrt.c:(.text+0xe5a71): undefined reference to `bgrt_tab'
>> bgrt.c:(.text+0xe5a91): undefined reference to `bgrt_tab'

   drivers/built-in.o: In function `show_type':
>> bgrt.c:(.text+0xe5c31): undefined reference to `bgrt_tab'
   drivers/built-in.o:bgrt.c:(.text+0xe5c51): more undefined references to `bgrt_tab' follow
   drivers/built-in.o: In function `bgrt_init':
   bgrt.c:(.init.text+0x8931): undefined reference to `bgrt_image'
   bgrt.c:(.init.text+0x8932): undefined reference to `bgrt_image_size'
   bgrt.c:(.init.text+0x8950): undefined reference to `bgrt_image'
   bgrt.c:(.init.text+0x8960): undefined reference to `bgrt_image_size'

The problem is that all these undefined names are provided by
arch/x86/platform/efi/efi-bgrt.c - which is obviously not available
to the ia64 build.

It doesn't seem useful to provide the BGRT support for Itanium
(many systems are headless and have no graphics at all). So
just don't let users configure this driver on non-X86 machines.

acpi: remove reference to ACPI_HOTPLUG_IO

2013-03-24T22:56:41+00:00

The Kconfig entry for ACPI Container and Module Devices got
added in v2.6.11. Its default value has always been set to
    (ACPI_HOTPLUG_MEMORY || ACPI_HOTPLUG_CPU || ACPI_HOTPLUG_IO)

But the Kconfig symbol ACPI_HOTPLUG_IO has never existed. So it's
pointless to use it to set this default value.
