parentx86/speculation: Simplify indirect_branch_prediction_barrier() (diff)
parentLinux 4.15 (diff)
Merge tag 'v4.15' into x86/pti, to be able to merge dependent changes
Time has come to switch PTI development over to a v4.15 base - we'll still try to make sure that all PTI fixes backport cleanly to v4.14 and earlier. Signed-off-by: Ingo Molnar <mingo@kernel.org>
