Subject: compiling of tools/perf fail on x86 64bit kernel and 32bit userspace

Hi,

with latest git, i cannot compile perf on 32 bit userspace with a 64 bit
kernel.

~/src/linux-2.6/tools/perf$ make
PERF_VERSION = 2.6.39.rc6.224.g06d006f
GEN common-cmds.h
* new build flags or prefix
CC perf.o
CC builtin-annotate.o
CC builtin-bench.o
CC bench/sched-messaging.o
CC bench/sched-pipe.o
CC bench/mem-memcpy-x86-64-asm.o
bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages:
bench/../../../arch/x86/lib/memcpy_64.S:28: Error: bad register name `%rdi'
bench/../../../arch/x86/lib/memcpy_64.S:33: Error: invalid instruction
suffix for `movs'

ARCH=x86 make works fine

thanks,
riccardo
