[PATCH 0.5/23] memblock: Fix include breakages caused by 24aa07882b

[Tejun Heo <tj@kernel.org>]

24aa07882b (memblock, x86: Replace memblock_x86_reserve/free_range()
with generic ones) removed arch/x86/include/asm/memblock.h and dropped
its inclusion from include/linux/memblock.h which breaks other
architectures which depended on the generic memblock.h pulling in the
arch specific one.

However, the proper fix isn't adding back the asm inclusion.  memblock
doesn't have any arch dependent part and doesn't need arch specific
header file and asm/memblock.h files are either practically empty or
contain mostly unrelated arch specific stuff.

* In microblaze, sh, powerpc and sparc, asm/memblock.h is either empty
  or just contains unused MEMBLOCK_DBG() macro.  Remove it.

* In arm and unicore32, asm/memblock.h contains arch specific stuff.
  Include it directly from its users.  It might be a good idea to
  rename the header file to avoid confusion.

Build fix for arm and unicore32 for the current tip:x86/memblock.  Not
really part of this series but should be applied first, so...  This
patch doesn't affect further patches other than triggering some offset
warnings.

I've updated the following git branch to contain this patch and one
more updated patch (soon to be posted).

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git memblock

Commit ID should be 46c66825fc9a398f06f72732ed1a9d4fe89f6805.

Thanks.
