[0/5] jump_label: Fix __ro_after_init keys for modules & annotate some keys

Hi folks,

After chatting about deferring IPIs [1] at LPC I had another look at my patches
and realized a handful of them could already be sent as-is.

This series contains the __ro_after_init static_key bits, which fixes
__ro_after_init keys used in modules (courtesy of PeterZ) and flags more keys as
__ro_after_init.

Cheers,
Valentin

  context_tracking: Make context_tracking_key __ro_after_init

  x86/speculation: Make mds_user_clear __ro_after_init
