Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner: "A collection of assorted fixes: - Fix for the pinned cr0/4 fallout which escaped all testing efforts because the kvm-intel module was never loaded when the kernel was compiled with CONFIG_PARAVIRT=n. The cr0/4 accessors are moved out of line and static key is now solely used in the core code and therefore can stay in the RO after init section. So the kvm-intel and other modules do not longer reference the (read only) static key which the module loader tried to update. - Prevent an infinite loop in arch_stack_walk_user() by breaking out of the loop once the return address is detected to be 0. - Prevent the int3_emulate_call() selftest from corrupting the stack when KASAN is enabled. KASASN clobbers more registers than covered by the emulated call implementation. Convert the int3_magic() selftest to a ASM function so the compiler cannot KASANify it. - Unbreak the build with old GCC versions and with the Gold linker by reverting the 'Move of _etext to the actual end of .text'. In both cases the build fails with 'Invalid absolute R_X86_64_32S relocation: _etext' - Initialize the context lock for init_mm, which was never an issue until the alternatives code started to use a temporary mm for patching. - Fix a build warning vs. the LOWMEM_PAGES constant where clang complains rightfully about a signed integer overflow in the shift operation by converting the operand to an ULL. - Adjust the misnamed ENDPROC() of common_spurious in the 32bit entry code" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/stacktrace: Prevent infinite loop in arch_stack_walk_user() x86/asm: Move native_write_cr0/4() out of line x86/pgtable/32: Fix LOWMEM_PAGES constant x86/alternatives: Fix int3_emulate_call() selftest stack corruption x86/entry/32: Fix ENDPROC of common_spurious Revert "x86/build: Move _etext to actual end of .text" x86/ldt: Initialize the context lock for init_mm
