[PATCH 0/4] x86-32: Clean up GS segment handling

[Brian Gerst]

Since commit 3fb0fdb3bbe ("Make the canary into a regular percpu
variable"), the GS segment is no longer switched on kernel entry for
32-bit kernels.  Clean up the remaining code that handled lazy GS
switching.

Brian Gerst (4):
  x86-32: Simplify ELF_CORE_COPY_REGS
  ELF: Remove elf_core_copy_kernel_regs()
  x86-32: Remove lazy GS macros
  x86: Merge load_gs_index()
