aa8aba6944 [ARM] S3C: Do not kmalloc/kfree during inner suspend code.
The PM CRC checking code kmallocs an area to save a set of
CRC values during suspend. This triggers a warning due to the
call of a function that might sleep whilst the system is not
in a valid state to do so.

Move the allocation and free to points in the suspend and resume
process where they can call a function that might-sleep.

663a83048c [ARM] S3C: Avoid checking the task stackpage in pm-check
When doing the CRC check of the memory, avoid checking
the page that our stack is residing in as this changes
during the execution of the suspend and resume.

840eeeb880 [ARM] S3C: Fix warnings in the PM memory CRC code
Fix warnings from struct resource being bigger than unsigned long by
forcing the type. We are only a 32bit platform so no physical memory
addresses will be too big to fit in this.

549c7e33ae [ARM] S3C: Split the resume memory check code from pm.c
Split the optional memory check code out of the pm.c file
as it is quite a big #ifdef block and as-such can be moved
out and simply compiled when the configuration is set.
