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" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/pgtable: Don't set huge PUD/PMD on non-leaf entries x86/pti: Leave kernel text global for !PCID x86/pti: Never implicitly clear _PAGE_GLOBAL for kernel image x86/pti: Enable global pages for shared areas x86/mm: Do not forbid _PAGE_RW before init for __ro_after_init x86/mm: Comment _PAGE_GLOBAL mystery x86/mm: Remove extra filtering in pageattr code x86/mm: Do not auto-massage page protections x86/espfix: Document use of _PAGE_GLOBAL x86/mm: Introduce "default" kernel PTE mask x86/mm: Undo double _PAGE_PSE clearing x86/mm: Factor out pageattr _PAGE_GLOBAL setting x86/entry/64: Drop idtentry's manual stack switch for user entries x86/uapi: Fix asm/bootparam.h userspace compilation errors
