When VRAM is running out it's possible that the client's push buffers get
evicted to main memory. When they're validated back in, the GPU may
be used for the copy back to VRAM, but the existing synchronisation code
only deals with inter-channel sync, not sync between PFIFO and PGRAPH on
the same channel. This leads to PFIFO fetching from command buffers that
haven't quite been copied by PGRAPH yet.
This patch marks push buffers as so, and forces any GPU-assisted buffer
moves to be done on a different channel, which triggers the correct
synchronisation to happen before we submit them.

After rlimits tree was merged we get the following errors:
security/apparmor/lsm.c:663:2: warning: initialization from incompatible pointer type
It is because AppArmor was merged in the meantime, but uses the old
prototype. So fix it by adding struct task_struct as a first parameter
of apparmor_task_setrlimit.
NOTE that this is ONLY a compilation warning fix (and crashes caused
by that). It needs proper handling in AppArmor depending on who is the
'task'.

Commit b45cfba4e9 (vt,console,kdb:
implement atomic console enter/leave functions) introduced the ability
to atomically change the console mode with kernel mode setting but did
not preserve the state of the console_blanked variable.
The console_blanked variable must be restored when executing the
con_debug_leave() or further kernel mode set changes (such as using
chvt X) will fail to correctly set the state of console.

If CONFIG_KGDB_KDB is set and CONFIG_KALLSYMS is not set the kernel
will fail to build with the error:
kernel/built-in.o: In function `kallsyms_symbol_next':
kernel/debug/kdb/kdb_support.c:237: undefined reference to `kdb_walk_kallsyms'
kernel/built-in.o: In function `kallsyms_symbol_complete':
kernel/debug/kdb/kdb_support.c:193: undefined reference to `kdb_walk_kallsyms'
The kdb_walk_kallsyms needs a #ifdef proper header to match the C
implementation. This patch also fixes the compiler warnings in
kdb_support.c when compiling without CONFIG_KALLSYMS set. The
compiler warnings are a result of the kallsyms_lookup() macro not
initializing the two of the pass by reference variables.

If a video head and keyboard are hooked up, specifying "console=ttyS0"
or similar to use a serial console will not work properly.
The key issue is that we must register all serial console capable
devices with register_console(), otherwise the command line specified
device won't be found. The sun serial drivers would only register
themselves as console devices if the OpenFirmware specified console
device node matched. To fix this part we now unconditionally get
the serial console register by setting serial_drv->cons always.
Secondarily we must not add_preferred_console() using the firmware
provided console setting if the user gaven an override on the kernel
command line using "console=" The "primary framebuffer" matching
logic was always triggering o n openfirmware device node match, make
it not when a command line override was given.

The Linux ACPI core locates the ACPI video devices for us and marks them
with ACPI_VIDEO_HID. Use that information to locate the video device
instead of a half-baked hunt for _BCL.
This uncouples the detection of the number of backlight brightness
levels on ThinkPads from the ACPI paths in vid_handle.
With this change, the driver should be able to always detect whether the
ThinkPad uses a 8-level or 16-level brightness scale even on newer
models for which the vid_handle paths have not been updated yet.
It will skip deactivated devices in the ACPI device tree, which is a
change in behaviour.

The annotate browser is not returning it as expected by builtin-annotate

Fix it by returning the exit key and also adding the RIGHT key as a exit

Commit 5a5f561 (convert OMAP3 PRCM macros to the _SHIFT/_MASK suffixes)
mistakenly removed the check for PER when disabling the IO chain.
During idle, if the PER powerdomain transitions into a lower state
and CORE does not, the IO pad wakeups are not being disabled in
the idle path after they are enabled. This can happen with the
lower C-states when using CPUidle for example.
This patch ensures that the check for disabling IO wakeups also checks
for PER transitions, matching the check done to enable IO wakeups.
Found when debugging PM/CPUidle related problems reported by Ameya
Palande <ameya.palande@nokia.com>. Problems were triggered
particularily on boards with UART2 consoles (n900, Overo) since UART2
is in the PER powerdomain.
Tested on l-o master (omap3_defonfig + CONFIG_CPU_IDLE=y) as well
as with current PM branch. Boards tested: n900, Overo, omap3evm.
