#     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"
