Thomas Gleixner 2cb15faaed x86/cpu: Re-enable stackprotector ... Commit 5416c26635 ("x86: make sure load_percpu_segment has no stackprotector") disabled the stackprotector for cpu/common.c because of load_percpu_segment(). Back then the boot stack canary was initialized very early in start_kernel(). Switching the per CPU area by loading the GDT caused the stackprotector to fail with paravirt enabled kernels as the GSBASE was not updated yet. In hindsight a wrong change because it would have been sufficient to ensure that the canary is the same in both per CPU areas. Commit d55535232c ("random: move rand_initialize() earlier") moved the stack canary initialization to a later point in the init sequence. As a consequence the per CPU stack canary is 0 when switching the per CPU areas, so there is no requirement anymore to exclude this file. Add a comment to load_percpu_segment().
