[PATCH 0/3] retpoline: add clang support + Kconfig selectable

Posted by Roger Pau Monne 2 years, 2 months ago

Hello,

The following series adds retpoline support for clang builds, and also
allows the user to select whether to enable retpoline support at build
time via a new Kconfig option.

I've tried adding a suitable description to the Kconfig option, but I'm
sure there's room for improvement.

Thanks, Roger.

Roger Pau Monne (3):
  x86/retpoline: rename retpoline Kconfig check to include GCC prefix
  x86/clang: add retpoline support
  x86/Kconfig: introduce option to select retpoline usage
