Subject: [RFC v2 09/23] x86: pm-trace - Adapt assembly for PIE support

Change assembly to use the new _ASM_GET_PTR 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.
