Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 pti updates from Thomas Gleixner:
"Another series of PTI related changes:
- Remove the manual stack switch for user entries from the idtentry
code. This debloats entry by 5k+ bytes of text.
- Use the proper types for the asm/bootparam.h defines to prevent
user space compile errors.
- Use PAGE_GLOBAL for !PCID systems to gain back performance
- Prevent setting of huge PUD/PMD entries when the entries are not
leaf entries otherwise the entries to which the PUD/PMD points to
and are populated get lost"
