This is the prevent previous stores from overlapping the block stores
done by the memcpy loop.
Based upon a glibc patch by Jose E. Marchesi

sparc64: Fix return value of Niagara-2 memcpy.2012-09-27T08:06:43+00:00David S. Millerdavem@davemloft.net2012-09-27T08:06:43+00:00urn:sha1:1b62ca7bf5775bed048032b7e779561e1fe66aa0
It gets clobbered by the kernel's VISEntryHalf, so we have to save it
in a different register than the set clobbered by that macro.
The instance in glibc is OK and doesn't have this problem.

sparc64: Consistently use fsrc2 rather than fmovd in optimized asm.2012-06-27T08:25:23+00:00David S. Millerdavem@davemloft.net2012-06-27T08:25:23+00:00urn:sha1:6f1d827f299085a48cb3a987e1487e16f1a980c9
Because fsrc2, unlike fmovd, does not update the %fsr register.

o Renamed files in sparc64 to <name>_64.S when identical
to sparc32 files.
o iomap.c were equal for sparc32 and sparc64
o adjusted sparc/Makefile now we have only one lib/
