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: #
