Andrew Morton 09f9390d79 drivers/staging/speakup/devsynth.c: fix "buffer size is not provably correct" error
x86_64 allmodconfig:

arch/x86/include/asm/uaccess_64.h:64: error: call to 'copy_from_user_overflow' declared with attribute error: copy_from_user() buffer size is not provably correct

I'm not sure what was unprovable about it, but size_t is the correct type
anyway.

Also replace needless min_t() with min()

Jesper Juhl 37ca936e1d Remove unneeded version.h includes from drivers/staging/speakup/
It was pointed out by 'make versioncheck' that some includes of
linux/version.h are not needed in drivers/staging/speakup/.
This patch removes them.

Peter Huewe 6263ba5519 staging: speakup: Use kstrtoul_from_user
This patch replaces the code for getting an unsigned long from a
userspace buffer by a simple call to kstroul_from_user.
This makes it easier to read and less error prone.

Christopher Brannon 87be424a9a Staging: speakup: fix an out-of-bounds error.
The cur_item variable from keyhelp.c is an index into a table of
messages.  The following condition should always hold:
MSG_FUNCNAMES_START + cur_item <= MSG_FUNCNAMES_END.
The check in keyhelp.c was wrong.  It allowed cur_item to be
incremented to an out-of-bounds value.

Christopher Brannon 628f34282d staging: speakup: more fixes for init-failure handling.
We still leaked many resources when Speakup failed to initialize.
Examples of leaked resources include:
/dev/synth, keyboard or VT notifiers, and heap-allocated st_spk_t
structs.
This is fixed.

* We now use PTR_ERR to detect kthread_create failure
(thank you Dan Carpenter).

* The loop which frees members of the speakup_console array now iterates
over the whole array, not stopping at the first NULL value.  Fixes
a possible memory leak.  Safe because kfree(NULL) is a no-op.

* The order of some initializations was changed.  The safe ones, which
will never fail, are performed first.

Christoph Lameter 4a6f4fe837 drivers: Replace __get_cpu_var with __this_cpu_read if not used for an address.
__get_cpu_var() can be replaced with this_cpu_read and will then use a single
read instruction with implied address calculation to access the correct per cpu
instance.

However, the address of a per cpu variable passed to __this_cpu_read() cannot be
determed (since its an implied address conversion through segment prefixes).
Therefore apply this only to uses of __get_cpu_var where the addres of the
variable is not used.

V3->V4:
	- Move one instance of this_cpu_inc_return to a later patch
	  so that this one can go in without percpu infrastructrure
	  changes.
