Merge branch 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cleanups from Ingo Molnar:
 "Misc small cleanups: removal of superfluous code and coding style
  cleanups mostly"

* 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/kexec: Make variable static and config dependent
  x86/defconfigs: Remove useless UEVENT_HELPER_PATH
  x86/amd_nb: Make hygon_nb_misc_ids static
  x86/tsc: Move inline keyword to the beginning of function declarations
  x86/io_delay: Define IO_DELAY macros in C instead of Kconfig
  x86/io_delay: Break instead of fallthrough in switch statement
