c044cf14b0 Fix wrong copying processing for last bytes in x86-32 wcscpy 
Wrong copy algorithm for last bytes, not thread safety.
In some particular cases it uses the destination
memory beyond the string end for
16-byte load, puts changes into that part that is relevant
to destination string and writes whole 16-byte chunk into memory.
I have a test case where the memory beyond the string end contains
malloc/free data, that appear corrupted in case free() updates
it in between the 16-byte read and 16-byte write.

fbeb5f4db1 rtld, i386: Fix cfi directive in audit trampoline code 
_dl_runtime_profile function has wrong cfi directive when
rewinding stack back for the pltexit path.

Only 8 bytes - 2 'pop edx' instructions from the pltentry-only
code should be rewinded back.

With attached patch, I'm able to rewind stack correctly
throught the rtld code from audit library callback.

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.

6f6f1215f6 Support multiarch for i686. 
This patch adds multiarch support when configured for i686.  I modified
some x86-64 functions to support 32bit. I will contribute 32bit SSE string
and memory functions later.

da97dfdcfa Add sigstack handling to Linux ____longjmp_chk on i386. 
All other i386 ports need to provide their own versions.

0212596218 libc part of prelink IFUNC support. 
The dl-lookup.c changes are needed for prelink (support in prelink
checked into SVN, tested for both i?86 and x86-64), dl-irel.h just
something I discovered by code inspection.

fd96f06208 Small optimization of STT_GNU_IFUNC handling. 
The test to call the indirect function now includes a subtest to
checked whether the symbol is defined.  When coming to that point
this is almost always the case.  The test for STT_GNU_IFUNC on the
other hand rarely is true.  Move it to the front means we don't have
to perform the second test unless really necessary.

b50f8e42ba Check for valid stack frame in longjmp. 
If longjmp restores the stack frame to an address which is beyond
the stack frame at the time of the longjmp call it would install
an uninitialized stack frame.  If compiled with _FORTIFY_SOURCE
defined, longjmp will now bail out in this situation.
