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 # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 753c8d9b7d81206bb5d011b28abe829d364b028e # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x59A03C22 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # yes \n | make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/fs/afs/dir.c: In function 'afs_dir_set_page_dirty': /kisskb/src/fs/afs/dir.c:50:1: warning: no return statement in function returning non-void [-Wreturn-type] } ^ /kisskb/src/arch/powerpc/kernel/eeh.c:1779:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] static int proc_eeh_show(struct seq_file *m, void *v) ^~~~~~~~~~~~~ /kisskb/src/kernel/watchdog.c:47:23: warning: 'watchdog_allowed_mask' defined but not used [-Wunused-variable] static struct cpumask watchdog_allowed_mask __read_mostly; ^~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/hwtracing/intel_th/msu.c: In function 'msc_buffer_win_alloc': /kisskb/src/drivers/hwtracing/intel_th/msu.c:783:21: warning: unused variable 'i' [-Wunused-variable] int ret = -ENOMEM, i; ^ /kisskb/src/drivers/hwtracing/intel_th/msu.c: In function 'msc_buffer_win_free': /kisskb/src/drivers/hwtracing/intel_th/msu.c:863:6: warning: unused variable 'i' [-Wunused-variable] int i; ^ /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c: In function 'soc15_set_ip_blocks': /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c:630:3: warning: #warning "Enable CONFIG_DRM_AMD_DC for display support on SOC15."
