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()
