2011-05-11sparc32: Fixed unaligned memory copying in function ↵Tkhai Kirill
__csum_partial_copy_sparc_generic When we are in the label cc_dword_align, registers %o0 and %o1 have the same last 2 bits, but it's not guaranteed one of them is zero. So we can get unaligned memory access in label ccte. Example of parameters which lead to this: %o0=0x7ff183e9, %o1=0x8e709e7d, %g1=3 With the parameters I had a memory corruption, when the additional 5 bytes were rewritten. This patch corrects the error. One comment to the patch. We don't care about the third bit in %o1, because cc_end_cruft stores word or less.

2008-12-04sparc: prepare lib/ for unificationSam Ravnborg
Identical named files renamed to <name>_32.S Refactored Makefile to prepare for unification. Linking order was altered slightly - but this is a lib.a file so it should not matter. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
