Hello,

This patch adds clobber regs into the play as assembly trashes random registers.
I was bitten by this while doing MSR I/O because ECX got corrupted. I attempted
to create nice barrier for GCC while changing the stack location too.

The memcpy code was taken from Linux kernel, dont know to whom attribute the
copyright on it. If it is OK with the note, otherwise:

Thanks,
Rudolf
