| |
Hi Thomas,
Please pull these READ_IMPLIES_EXEC cleanups. They've got Acks, and have been sitting without further commented since v4: https://lore.kernel.org/lkml/20200225051307.6401-1-keescook@chromium.org/#r Catalin specifically asked me during Plumbers if I could get this series refreshed and finalized, so here we are! :) I'd wanted to keep these all together so per-arch RIE special cases were changed at the same time.
Thanks!
