Linus Torvalds b1b6f83ac9 Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip ... Pull x86 mm changes from Ingo Molnar: "PCID support, 5-level paging support, Secure Memory Encryption support The main changes in this cycle are support for three new, complex hardware features of x86 CPUs: - Add 5-level paging support, which is a new hardware feature on upcoming Intel CPUs allowing up to 128 PB of virtual address space and 4 PB of physical RAM space - a 512-fold increase over the old limits. (Supercomputers of the future forecasting hurricanes on an ever warming planet can certainly make good use of more RAM.) Many of the necessary changes went upstream in previous cycles, v4.14 is the first kernel that can enable 5-level paging. This feature is activated via CONFIG_X86_5LEVEL=y - disabled by default. (By Kirill A. Shutemov) - Add 'encrypted memory' support, which is a new hardware feature on upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system RAM to be encrypted and decrypted (mostly) transparently by the CPU, with a little help from the kernel to transition to/from encrypted RAM. Such RAM should be more secure against various attacks like RAM access via the memory bus and should make the radio signature of memory bus traffic harder to intercept (and decrypt) as well. This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled by default. (By Tom Lendacky) - Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a hardware feature that attaches an address space tag to TLB entries and thus allows to skip TLB flushing in many cases, even if we switch mm's. (By Andy Lutomirski) All three of these features were in the works for a long time, and it's coincidence of the three independent development paths that they are all enabled in v4.14 at once" * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (65 commits) x86/mm: Enable RCU based page table freeing (CONFIG_HAVE_RCU_TABLE_FREE=y) x86/mm: Use pr_cont() in dump_pagetable() x86/mm: Fix SME encryption stack ptr handling kvm/x86: Avoid clearing the C-bit in rsvd_bits() x86/CPU: Align CR3 defines x86/mm, mm/hwpoison: Clear PRESENT bit for kernel 1:1 mappings of poison pages acpi, x86/mm: Remove encryption mask from ACPI page protection type x86/mm, kexec: Fix memory corruption with SME on successive kexecs x86/mm/pkeys: Fix typo in Documentation/x86/protection-keys.txt x86/mm/dump_pagetables: Speed up page tables dump for CONFIG_KASAN=y x86/mm: Implement PCID based optimization: try to preserve old TLB entries using PCID x86: Enable 5-level paging support via CONFIG_X86_5LEVEL=y x86/mm: Allow userspace have mappings above 47-bit x86/mm: Prepare to expose larger address space to userspace x86/mpx: Do not allow MPX if we have mappings above 47-bit x86/mm: Rename tasksize_32bit/64bit to task_size_32bit/64bit() x86/xen: Redefine XEN_ELFNOTE_INIT_P2M using PUD_SIZE * PTRS_PER_PUD x86/mm/dump_pagetables: Fix printout of p4d level x86/mm/dump_pagetables: Generalize address normalization x86/boot: Fix memremap() related build failure ...		2017-09-04 12:21:28 -07:00
