Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/pti update from Thomas Gleixner: "Just a single change from the anti-performance departement: - Add a new PR_SPEC_DISABLE_NOEXEC option which allows to apply the speculation protections on a process without inheriting the state on exec. This remedies a situation where a Java-launcher has speculation protections enabled because that's the default for JVMs which causes the launched regular harmless processes to inherit the protection state which results in unintended performance degradation" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/speculation: Add PR_SPEC_DISABLE_NOEXEC
