Linus Torvalds 899ba79553 Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip ... Pull x86 fixes from Thomas Gleixner: "Speculation: - Make the microcode check more robust - Make the L1TF memory limit depend on the internal cache physical address space and not on the CPUID advertised physical address space, which might be significantly smaller. This avoids disabling L1TF on machines which utilize the full physical address space. - Fix the GDT mapping for EFI calls on 32bit PTI - Fix the MCE nospec implementation to prevent #GP Fixes and robustness: - Use the proper operand order for LSL in the VDSO - Prevent NMI uaccess race against CR3 switching - Add a lockdep check to verify that text_mutex is held in text_poke() functions - Repair the fallout of giving native_restore_fl() a prototype - Prevent kernel memory dumps based on usermode RIP - Wipe KASAN shadow stack before rewinding the stack to prevent false positives - Move the AMS GOTO enforcement to the actual build stage to allow user API header extraction without a compiler - Fix a section mismatch introduced by the on demand VDSO mapping change Miscellaneous: - Trivial typo, GCC quirk removal and CC_SET/OUT() cleanups" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/pti: Fix section mismatch warning/error x86/vdso: Fix lsl operand order x86/mce: Fix set_mce_nospec() to avoid #GP fault x86/efi: Load fixmap GDT in efi_call_phys_epilog() x86/nmi: Fix NMI uaccess race against CR3 switching x86: Allow generating user-space headers without a compiler x86/dumpstack: Don't dump kernel memory based on usermode RIP x86/asm: Use CC_SET()/CC_OUT() in __gen_sigismember() x86/alternatives: Lockdep-enforce text_mutex in text_poke*() x86/entry/64: Wipe KASAN stack shadow before rewind_stack_do_exit() x86/irqflags: Mark native_restore_fl extern inline x86/build: Remove jump label quirk for GCC older than 4.5.2 x86/Kconfig: Fix trivial typo x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+ x86/spectre: Add missing family 6 check to microcode check		2018-09-02 10:11:30 -07:00
