x86/debug: Disable CONFIG_X86_DECODER_SELFTEST in allmod/allyesconfigs
* Linus Torvalds <torvalds@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.)
