Merge branch 'akpm' (Andrew's patch-bomb) 

Merge Andrew's first set of patches:
 "Non-MM patches:

   - lots of misc bits

   - tree-wide have_clk() cleanups

   - quite a lot of printk tweaks.  I draw your attention to "printk:
     convert the format for KERN_<LEVEL> to a 2 byte pattern" which
     looks a bit scary.  But afaict it's solid.

   - backlight updates

   - lib/ feature work (notably the addition and use of memweight())

   - checkpatch updates

   - rtc updates

   - nilfs updates

   - fatfs updates (partial, still waiting for acks)

   - kdump, proc, fork, IPC, sysctl, taskstats, pps, etc

   - new fault-injection feature work"

Tool to run command with failslab or fail_page_alloc
----------------------------------------------------
In order to make it easier to accomplish the tasks mentioned above, we can use
tools/testing/fault-injection/failcmd.sh. Please run a command
"./tools/testing/fault-injection/failcmd.sh --help" for more information and
see the following examples.
Examples:
Run a command "make -C tools/testing/selftests/ run_tests" with injecting slab
allocation failure.
# ./tools/testing/fault-injection/failcmd.sh \
-- make -C tools/testing/selftests/ run_tests
Same as above except to specify 100 times failures at most instead of one time
at most by default.
# ./tools/testing/fault-injection/failcmd.sh --times=100 \
-- make -C tools/testing/selftests/ run_tests
Same as above except to inject page allocation failure instead of slab
allocation failure.
# env FAILCMD_TYPE=fail_page_alloc \

Notifier error injection
========================
Notifier error injection provides the ability to inject artifical errors to
specified notifier chain callbacks. It is useful to test the error handling of
notifier call chain failures which is rarely executed. There are kernel
modules that can be used to test the following notifiers.
* CPU notifier
* PM notifier
* Memory hotplug notifier
* powerpc pSeries reconfig notifier
CPU notifier error injection module
-----------------------------------
This feature can be used to test the error handling of the CPU notifiers by
injecting artifical errors to CPU notifier chain callbacks.
If the notifier call chain should be failed with some events notified, write
the error code to debugfs interface
/sys/kernel/debug/notifier-error-inject/cpu/actions/<notifier event>/error
Possible CPU notifier events to be failed are:
* CPU_UP_PREPARE
* CPU_UP_PREPARE_FROZEN
* CPU_DOWN_PREPARE
* CPU_DOWN_PREPARE_FROZEN
Example1: Inject CPU offline error (-1 == -EPERM)
# cd /sys/kernel/debug/notifier-error-inject/cpu
# echo -1 > actions/CPU_DOWN_PREPARE/error
# echo 0 > /sys/devices/system/cpu/cpu1/online
bash: echo: write error: Operation not permitted
Example2: inject CPU online error (-2 == -ENOENT)
# echo -2 > actions/CPU_UP_PREPARE/error
# echo 1 > /sys/devices/system/cpu/cpu1/online
bash: echo: write error: No such file or directory
PM notifier error injection module
----------------------------------
This feature is controlled through debugfs interface
/sys/kernel/debug/notifier-error-inject/pm/actions/<notifier event>/error
Possible PM notifier events to be failed are:
* PM_HIBERNATION_PREPARE
* PM_SUSPEND_PREPARE
* PM_RESTORE_PREPARE
Example: Inject PM suspend error (-12 = -ENOMEM)
# cd /sys/kernel/debug/notifier-error-inject/pm/
# echo -12 > actions/PM_SUSPEND_PREPARE/error
# echo mem > /sys/power/state
bash: echo: write error: Cannot allocate memory
Memory hotplug notifier error injection module
----------------------------------------------
This feature is controlled through debugfs interface
/sys/kernel/debug/notifier-error-inject/memory/actions/<notifier event>/error
Possible memory notifier events to be failed are:
* MEM_GOING_ONLINE
* MEM_GOING_OFFLINE
Example: Inject memory hotplug offline error (-12 == -ENOMEM)
# cd /sys/kernel/debug/notifier-error-inject/memory
# echo -12 > actions/MEM_GOING_OFFLINE/error
# echo offline > /sys/devices/system/memory/memoryXXX/state
bash: echo: write error: Cannot allocate memory
powerpc pSeries reconfig notifier error injection module
--------------------------------------------------------
This feature is controlled through debugfs interface
/sys/kernel/debug/notifier-error-inject/pSeries-reconfig/actions/<notifier event>/error
Possible pSeries reconfig notifier events to be failed are:
* PSERIES_RECONFIG_ADD
* PSERIES_RECONFIG_REMOVE
* PSERIES_DRCONF_MEM_ADD
* PSERIES_DRCONF_MEM_REMOVE
For more usage examples
-----------------------
There are tools/testing/selftests using the notifier error injection features
for CPU and memory notifiers.
* tools/testing/selftests/cpu-hotplug/on-off-test.sh
* tools/testing/selftests/memory-hotplug/on-off-test.sh
These scripts first do simple online and offline tests and then do fault
injection tests if notifier error injection module is available.

either a pipe handler or a fully qualified path. (For more details
on this limitation, see CVE-2006-2451.) This mode is appropriate
when administrators are attempting to debug problems in a normal
environment, and either have a core dump pipe handler that knows
to treat privileged core dumps with care, or specific directory
defined for catching core dumps. If a core dump happens without
a pipe handler or fully qualifid path, a message will be emitted
to syslog warning about the lack of a correct setting.
