Grant Likely f1ca09b2b5 of: Fix missing includes
This patch fixes missing includes from a number of .c files because
the code (wrongfully) depended on prom.h including them.  The include
of linux/of_address.h was removed in microblaze prom.h in commit
"of/address: Clean up function declarations" (sha1 id 22ae782f8), but
not fixed in some callers.  This patch fixes them up.

Jiri Slaby 7cb4dc9fc9 AppArmor: fix task_setrlimit prototype
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'.

Jason Wessel beed5336eb vt,console,kdb: preserve console_blanked while in kdb
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.

Jason Wessel b590cddfa6 kdb: fix compile error without CONFIG_KALLSYMS
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.

David S. Miller 0a492896ac sparc: Really fix "console=" for serial consoles.
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.

Henrique de Moraes Holschuh 122f26726b thinkpad-acpi: find ACPI video device by synthetic HID
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

Mikael Pettersson 21d93e2e29 ARM: 6329/1: wire up sys_accept4() on ARM
sys_accept4() was added in kernel 2.6.28, but ARM was not updated
to include it.  The number and types of parameters is such that
no ARM-specific processing is needed, so wiring up sys_accept4()
just requires defining __NR_accept4 and adding a direct call in
the syscall entry table.

Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original
accept4() test program, modified to define __NR_accept4 for ARM.

Using the updated unistd.h also eliminates a warning then building
glibc (2.10.2 and newer) about accept4() being unimplemented.

Chris Metcalf a5854dd7f3 arch/tile: don't validate CROSS_COMPILE needlessly
With this change, the arch/tile Makefile will only check for a valid
combination of CROSS_COMPILE vs "uname -m" for a few common targets
that are typically the ones we get wrong (vmlinux, all, and modules).
The change handles the case of an empty "make" goal like "make all".

Linus Torvalds d7824370e2 mm: fix up some user-visible effects of the stack guard page
This commit makes the stack guard page somewhat less visible to user
space. It does this by:

 - not showing the guard page in /proc/<pid>/maps

   It looks like lvm-tools will actually read /proc/self/maps to figure
   out where all its mappings are, and effectively do a specialized
   "mlockall()" in user space.  By not showing the guard page as part of
   the mapping (by just adding PAGE_SIZE to the start for grows-up
   pages), lvm-tools ends up not being aware of it.

 - by also teaching the _real_ mlock() functionality not to try to lock
   the guard page.

   That would just expand the mapping down to create a new guard page,
   so there really is no point in trying to lock it in place.

It would perhaps be nice to show the guard page specially in
/proc/<pid>/maps (or at least mark grow-down segments some way), but
let's not open ourselves up to more breakage by user space from programs
that depends on the exact deails of the 'maps' file.

Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools
source code to see what was going on with the whole new warning.
