memstick: ms_block: fix compile issue
As suggested by Geert Uytterhoeven:
: http://kisskb.ellerman.id.au/kisskb/buildresult/7280352/
: arch/m68k/include/asm/hardirq.h:23:20: error: expected ')' before 'DRIVER_NAME'
: make[4]: *** [drivers/memstick/core/ms_block.o] Error 1
:
: The reason for this is that pr_fmt() references DRIVER_NAME and is defined
: before the first include, while DRIVER_NAME is only defined in ms_block.h,
: which is the last included file. If any subsequent include file uses
: pr_fmt() (e.g. the call to pr_crit() in arch/m68k/include/asm/hardirq.h),
: this causes a build failure.
:
: I suggest moving the DRIVER_NAME define to ms_block.c. Cfr. memstick.c
: and mspro_block.c, who already have their own definition.

commit 5ab1c30 ("coredump: pass siginfo_t* to do_coredump() and below, not
merely signr") added siginfo_t to linux/coredump.h but forgot to include
asm/siginfo.h. This breaks the build for UML/i386. (And any other arch
where asm/siginfo.h is not magically preincluded...)

raid5: create multiple threads to handle stripes
This is a new tempt to make raid5 handle stripes in multiple threads, as
suggested by Neil to have maxium flexibility and better numa binding. It
basically is a combination of my first and second generation patches. By
default, no multiple thread is enabled (all stripes are handled by raid5d).
An example to enable multiple threads:
#echo 3 > /sys/block/md0/md/auxthread_number
This will create 3 auxiliary threads to handle stripes. The threads can run
on any cpus and handle stripes produced by any cpus.
#echo 1-3 > /sys/block/md0/md/auxth0/cpulist
This will bind auxiliary thread 0 to cpu 1-3, and this thread will only handle
stripes produced by cpu 1-3. User tool can further change the thread's
affinity, but the thread can only handle stripes produced by cpu 1-3 till the
sysfs entry is changed again.
If stripes produced by a CPU aren't handled by any auxiliary thread, such
stripes will be handled by raid5d. Otherwise, raid5d doesn't handle any
stripes.

thermal, cpufreq: Fix build when CPU_FREQ_TABLE isn't configured
Commit 023614183768 ("thermal: add generic cpufreq cooling
implementation") requires cpufreq_frequency_get_table(), but that
function is only defined for CONFIG_CPU_FREQ_TABLE resulting in the
following build error:
drivers/built-in.o: In function `cpufreq_get_max_state':
drivers/thermal/cpu_cooling.c:259: undefined reference to `cpufreq_frequency_get_table'
drivers/built-in.o: In function `get_cpu_frequency':
drivers/thermal/cpu_cooling.c:129: undefined reference to `cpufreq_frequency_get_table'
Fix it by selecting CONFIG_CPU_FREQ_TABLE for such a configuration.
It turns out CONFIG_EXYNOS_THERMAL also needs CONFIG_CPU_FREQ_TABLE, so
select it there as well.

parport: dead code in pp_write
We always update bytes_written before we check signal_pending so it
follows that we can't get a signal return for 0 bytes so we don't
need to check in the singal path. The cases a signal causes an earlier
abort are handled before this and will not hit this path
