Subject: [PATCH] hwf-x86: fix use of wrong operand type
* src/hwf-x86.c (get_cpuid): Use xchg for swapping %ebx back
and forth between operand register.
--
HW feature routine was giving wrong results with certain compiler &
compiler flag combinations on i386. Issue was that "=g" operand was
used which caused problem if compiler allocated %ebx register for
this operand. CPUID assembly block attempts to save %ebx as in older
GCC versions this register was fixed for GOT pointer use and could
not be modified otherwise (could not be used as operand or clobber).
