It ended up being suboptimal in # various ways. # # This reworks the X86 irq stack handling: # # - Make the stack switching inline so the stackpointer manipulation is # not longer at an easy to find place. # # - Get rid of the unnecessary indirect call. # # - Avoid the double stack switching in interrupt return and reuse the # interrupt stack for softirq handling. # # - A objtool fix for CONFIG_FRAME_POINTER=y builds where it got # confused about the stack pointer manipulation" # # * tag 'x86-entry-2021-02-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # objtool: Fix stack-swizzle for FRAME_POINTER=y # um: Enforce the usage of asm-generic/softirq_stack.h # x86/softirq/64: Inline do_softirq_own_stack() # softirq: Move do_softirq_own_stack() to generic asm header # softirq: Move __ARCH_HAS_DO_SOFTIRQ to Kconfig # x86: Select CONFIG_HAVE_IRQ_EXIT_ON_IRQ_STACK # x86/softirq: Remove indirection in do_softirq_own_stack() # x86/entry: Use run_sysvec_on_irqstack_cond() for XEN upcall # x86/entry: Convert device interrupts to inline stack switching # x86/entry: Convert system vectors to irq stack macro # x86/irq: Provide macro for inlining irq stack switching # x86/apic: Split out spurious handling code # x86/irq/64: Adjust the per CPU irq stack pointer by 8 # x86/irq: Sanitize irq stack tracking # x86/entry: Fix instrumentation annotation # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 29c395c77a9a514c5857c45ceae2665e9bd99ac7 # < make -s -j 32 ARCH=arm O=/kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- mv78xx0_defconfig # < make -s -j 32 ARCH=arm O=/kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- help # make -s -j 32 ARCH=arm O=/kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- olddefconfig # make -s -j 32 ARCH=arm O=/kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- Completed OK # rm -rf /kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 # Build took: 0:01:17.429112
