It # has been submitted for review in four different waves: # # - IRQ stacks support for v7 SMP systems [0] # # - vmap'ed stacks support for v7 SMP systems[1] # # - extending support for both IRQ stacks and vmap'ed stacks for all # remaining configurations, including v6/v7 SMP multiplatform # kernels and uniprocessor configurations including v7-M [2] # # - fixes and updates in [3] # # - ftrace fixes and cleanups # # Make all flavors of ftrace available on all builds, regardless of # ISA choice, unwinder choice or compiler [4]: # # - use ADD not POP where possible # # - fix a couple of Thumb2 related issues # # - enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness # # - enable the graph tracer with the EABI unwinder # # - avoid clobbering frame pointer registers to make Clang happy # # - Fixes for the above" # # [0] https://lore.kernel.org/linux-arm-kernel/20211115084732.3704393-1-ardb@kernel.org/ # [1] https://lore.kernel.org/linux-arm-kernel/20211122092816.2865873-1-ardb@kernel.org/ # [2] https://lore.kernel.org/linux-arm-kernel/20211206164659.1495084-1-ardb@kernel.org/ # [3] https://lore.kernel.org/linux-arm-kernel/20220124174744.1054712-1-ardb@kernel.org/ # [4] https://lore.kernel.org/linux-arm-kernel/20220203082204.1176734-1-ardb@kernel.org/ # # * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (62 commits) # ARM: fix building NOMMU ARMv4/v5 kernels # ARM: unwind: only permit stack switch when unwinding call_with_stack() # ARM: Revert "unwind: dump exception stack from calling frame" # ARM: entry: fix unwinder problems caused by IRQ stacks # ARM: unwind: set frame.pc correctly for current-thread unwinding # ARM: 9184/1: return_address: disable again for CONFIG_ARM_UNWIND=y # ARM: 9183/1: unwind: avoid spurious warnings on bogus code addresses # Revert "ARM: 9144/1: forbid ftrace with clang and thumb2_kernel" # ARM: mach-bcm: disable ftrace in SMC invocation routines # ARM: cacheflush: avoid clobbering the frame pointer # ARM: kprobes: treat R7 as the frame pointer register in Thumb2 builds # ARM: ftrace: enable the graph tracer with the EABI unwinder # ARM: unwind: track location of LR value in stack frame # ARM: ftrace: enable HAVE_FUNCTION_GRAPH_FP_TEST # ARM: ftrace: avoid unnecessary literal loads # ARM: ftrace: avoid redundant loads or clobbering IP # ARM: ftrace: use trampolines to keep .init.text in branching range # ARM: ftrace: use ADD not POP to counter PUSH at entry # ARM: ftrace: ensure that ADR takes the Thumb bit into account # ARM: make get_current() and __my_cpu_offset() __always_inline # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 9c0e6a89b592f4c4e4d769dbc22d399ab0685159 # < make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=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_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig # < make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:6829:warning: override: reassigning to symbol STANDALONE .config:6835:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY # make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 # Build took: 0:03:51.550944
