[Xen-devel] [PATCH v2 07/27] x86: pm-trace - Adapt assembly for PIE support



Change assembly to use the new _ASM_MOVABS macro instead of _ASM_MOV for
the assembly to be PIE compatible.

Position Independent Executable (PIE) support will allow to extended the
KASLR randomization range below the -2G memory limit.
