x86/debug: Disable CONFIG_X86_DECODER_SELFTEST in allmod/allyesconfigs * Linus Torvalds <torva...@linux-foundation.org> wrote: Andi Kleen suggested to turn off CONFIG_X86_DECODER_SELFTEST=y in allyesconfig, because it costs a lot of CPU time. (In practice randconfig builds will cover this test frequently enough to provide build coverage.)
