X-Git-Tag: v2.6.38-rc1~490^2~82 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea7872b9d6a81101f6ba0ec141544a62fea35876;p=pandora-kernel.git perf bench: Add feature that measures the performance of the arch/x86/lib/memcpy_64.S memcpy routines via 'perf bench mem' This patch ports arch/x86/lib/memcpy_64.S to perf bench mem memcpy for benchmarking memcpy() in userland with tricky and dirty way. util/include/asm/cpufeature.h, util/include/asm/dwarf2.h, and util/include/linux/linkage.h are mostly dummy files with small wrappers, so that we are able to include memcpy_64.S unmodified.
