This is supported on x86 and target feature
xsave,xsaves
only.Perform a full or partial restore of the enabled processor states using the
state information stored in memory at mem_addr
.
xrstors
differs from xrstor
in that it can restore state components
corresponding to bits set in the IA32_XSS
MSR
; xrstors
cannot restore
from an xsave
area in which the extended region is in the standard form.

in rs_mask
, XCR0
, and
mem_addr.HEADER.XSTATE_BV
. mem_addr
must be aligned on a 64-byte
boundary.
