c0dde15b5d 32bit memset-sse2.S fails with uneven cache size 
32bit memset-sse2.S assumes cache size is multiple of 128 bytes.  If
it isn't true, memset-sse2.S will fail.  For example, a processor can
have 24576 KB L3 cache and 20 cores. That is 2516582 byte per core. Half
of it is 1258291, which isn't helpful for vector instructions.  This
patch rounds cache sizes to multiple of 256 bytes and adds "raw" cache
sizes.

02cea47161 Add x86 32-bit SSE4.2 string functions. 
This patch adds 32bit SSE4.2 string functions.  It uses -16L instead of
0xfffffffffffffff0L, which works for both 32bit and 64bit long.  Tested
on 32bit Core i7 and Core 2.
