Pull x86 page table isolation updates from Thomas Gleixner: "This is the final set of enabling page table isolation on x86: - Infrastructure patches for handling the extra page tables. - Patches which map the various bits and pieces which are required to get in and out of user space into the user space visible page tables. - The required changes to have CR3 switching in the entry/exit code. - Optimizations for the CR3 switching along with documentation how the ASID/PCID mechanism works. - Updates to dump pagetables to cover the user space page tables for W+X scans and extra debugfs files to analyze both the kernel and the user space visible page tables The whole functionality is compile time controlled via a config switch and can be turned on/off on the command line as well" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (32 commits) x86/ldt: Make the LDT mapping RO x86/mm/dump_pagetables: Allow dumping current pagetables x86/mm/dump_pagetables: Check user space page table for WX pages x86/mm/dump_pagetables: Add page table directory to the debugfs VFS hierarchy x86/mm/pti: Add Kconfig x86/dumpstack: Indicate in Oops whether PTI is configured and enabled x86/mm: Clarify the whole ASID/kernel PCID/user PCID naming x86/mm: Use INVPCID for __native_flush_tlb_single() x86/mm: Optimize RESTORE_CR3 x86/mm: Use/Fix PCID to optimize user/kernel switches x86/mm: Abstract switching CR3 x86/mm: Allow flushing for future ASID switches x86/pti: Map the vsyscall page if needed x86/pti: Put the LDT in its own PGD if PTI is on x86/mm/64: Make a full PGD-entry size hole in the memory map x86/events/intel/ds: Map debug buffers in cpu_entry_area x86/cpu_entry_area: Add debugstore entries to cpu_entry_area x86/mm/pti: Map ESPFIX into user space x86/mm/pti: Share entry text PMD x86/entry: Align entry text section to PMD boundary ... |
