Ville Juven 36cafbb37f mm/gran: Fix GRAN_ALIGNED() macro
GRAN_ALIGNED should check that the memory block's alignment (log2align)
is correct, not that the memory block is aligned with the granule size.

This fixes DEBUGASSERT() in mm_granfree:
_assert: Assertion failed : at file: mm_gran/mm_granfree.c:49

The assertion triggers if granule size != alignment.

Yanfeng Liu 102a62c7e3 mm/mm_gran: remove allocation size limitation
This patch refactors granule allocator to remove the 32 granules
limitation with the help of a gran_range_s structure and related
functions, see "mm_grantable.h" for details.

Below are the major functions explaining how this works:

- The gran_match() checks if a gran range all in the given state.
  it gives last mismatch position when fails free range matching.
- The gran_search() tries to find the position of a free range.
  It leverages last mismatch position from gran_match() to speed
  up the search.

range size handling is mainly in gran_match() and gran_set_().

Ville Juven 458ff380e5 mm/gran: Allow run-time execution of gran_reserve
User can ask for specific granules to be allocated.

This is useful for one thing only: when mmap() is called for a specific
vaddr. The parameter itself is non-sensical, this is just to satisfy
the POSIX standard.

Gregory Nutt 97339e47f1 Check return from nxsem_wait_initialize()
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is only for those files under graphics/, mm/, net/, sched/, wireless/bluetooth.

Still to do:  Files under fs/, drivers/, and arch.  The last is 116 files and will take some effort.
