[PATCH v2] local64.h: make <asm/local64.h> mandatory

[Randy Dunlap]

Make <asm-generic/local64.h> mandatory in include/asm-generic/Kbuild
and remove all arch/*/include/asm/local64.h arch-specific files since
they only #include <asm-generic/local64.h>.

This fixes build errors on arch/c6x/ and arch/nios2/ for
block/blk-iocost.c.

Build-tested on 21 of 25 arch-es. (tools problems on the others)

Yes, we could even rename <asm-generic/local64.h> to
<linux/local64.h> and change all #includes to use
<linux/local64.h> instead.

Would some $maintainer please plan to apply/merge this.

v2: instead of making local64.h a generic-y header file and adding it
to the missing arch/ header locations, make it a mandotory-y header file
and remove it from most arch/ header locations. (Christoph)
