glibc: Fix __memcpy_chk on non-SSE2 CPUs
Backport from upstream glibc: https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=132a1328eccd20621b77f7810eebbeec0a1af187 Note that the fix is only required when glibc is built for i686/multiarch, so is not applicable in the default oe-core x86 configuration (which builds glibc for i586 and therefore does not include SSE2 optimised memcpy etc). (From OE-Core rev: e643b9bc4c459ea8b59573cf67f2494388e7a377) Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

4Subject: [PATCH] Fix __memcpy_chk on non-SSE2 CPUs
5
6In commit 8b4416d, the 1: jump label in __mempcpy_chk was accidentally
7moved. This resulted in failures of mempcpy on CPU without SSE2.
