Subject[PATCH PTI v3 00/10] Clean up pgd handling and fix VSYSCALL and LDT
Date
This should fix some existing 5-level bugs and get VSYSCALL and LDT
working with PTI.

Changes from v1:
- vsyscalls actually work.
- Added the "Warn and fail" patch to prevent the testing goof I had on v1.
- Lots of cleanups

Andy Lutomirski (10):
x86/espfix/64: Fix espfix double-fault handling on 5-level systems
x86/pti: Vastly simplify pgd synchronization
x86/pti/64: Fix ESPFIX64 user mapping
Revert "x86/mm/pti: Disable native VSYSCALL"
x86/vsyscall/64: Explicitly set _PAGE_USER in the pagetable hierarchy
x86/vsyscall/64: Warn and fail vsyscall emulation in NATIVE mode
x86/pti: Map the vsyscall page if needed
x86/mm/64: Improve the memory map documentation
x86/mm/64: Make a full PGD-entry size hole in the memory map
x86/pti: Put the LDT in its own PGD if PTI is on
