Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm updates from Ingo Molnar: "The main changes in this cycle were: - Continued work to add support for 5-level paging provided by future Intel CPUs. In particular we switch the x86 GUP code to the generic implementation. (Kirill A. Shutemov) - Continued work to add PCID CPU support to native kernels as well. In this round most of the focus is on reworking/refreshing the TLB flush infrastructure for the upcoming PCID changes. (Andy Lutomirski)" * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits) x86/mm: Delete a big outdated comment about TLB flushing x86/mm: Don't reenter flush_tlb_func_common() x86/KASLR: Fix detection 32/64 bit bootloaders for 5-level paging x86/ftrace: Exclude functions in head64.c from function-tracing x86/mmap, ASLR: Do not treat unlimited-stack tasks as legacy mmap x86/mm: Remove reset_lazy_tlbstate() x86/ldt: Simplify the LDT switching logic x86/boot/64: Put __startup_64() into .head.text x86/mm: Add support for 5-level paging for KASLR x86/mm: Make kernel_physical_mapping_init() support 5-level paging x86/mm: Add sync_global_pgds() for configuration with 5-level paging x86/boot/64: Add support of additional page table level during early boot x86/boot/64: Rename init_level4_pgt and early_level4_pgt x86/boot/64: Rewrite startup_64() in C x86/boot/compressed: Enable 5-level paging during decompression stage x86/boot/efi: Define __KERNEL32_CS GDT on 64-bit configurations x86/boot/efi: Fix __KERNEL_CS definition of GDT entry on 64-bit configurations x86/boot/efi: Cleanup initialization of GDT entries x86/asm: Fix comment in return_from_SYSCALL_64() x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation ...
