22 always 0 to provide a full 64bit address space. The FS and GS segments are
25 Common FS and GS usage
37 The GS segment has no common use and can be used freely by
38 applications. GCC and Clang support GS based addressing via address space
41 Reading and writing the FS/GS base address
44 There exist two mechanisms to read and write the FS/GS base address:
50 Accessing FS/GS base with arch_prctl()
69 Accessing FS/GS base with the FSGSBASE instructions
73 instructions to access the FS and GS base registers directly from user
