KVM: SVM: Let gcc to choose which registers to save (i386)
This patch lets GCC to determine which registers to save when we
switch to/from a VCPU in the case of AMD i386
* Original code saves following registers:
ebx, ecx, edx, esi, edi, ebp
* Patched code:
- informs GCC that we modify following registers
using the clobber description:
ebx, ecx, edx, esi, edi
- rbp is saved (pop/push) because GCC seems to ignore its use in the clobber
description.
