Subject[PATCH v5 07/27] x86: pm-trace - Adapt assembly for PIE support
From
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 extend the
KASLR randomization range 0xffffffff80000000.
