H A Dfred.rst32 instruction (LKGS) for managing the state of the GS segment register.
71 LKGS behaves like the MOV to GS instruction except that it loads the
72 base address into the IA32_KERNEL_GS_BASE MSR instead of the GS
74 mucking with kernel GS, i.e., an operating system can always operate
75 with its own GS base address.
