kvm: x86: Fix xstate_required_size() to follow XSTATE alignment rule
CPUID.0xD.1.EBX enumerates the size of the XSAVE area (in compacted format) required by XSAVES. If CPUID.0xD.i.ECX[1] is set for a state component (i), this state component should be located on the next 64-bytes boundary following the preceding state component in the compacted layout. Fix xstate_required_size() to follow the alignment rule. AMX is the first state component with 64-bytes alignment to catch this bug. Signed-off-by:Jing Liu <jing2.liu@intel.com> Signed-off-by:
