In # particular, it breaks offlining and then re-onlining the boot CPU, which # we treat specially (and the BIOS does too). # # The symptoms are that we can offline the CPU, but it then does not come # back online again: # # smpboot: CPU 0 is now offline # smpboot: Booting Node 0 Processor 0 APIC 0x0 # smpboot: do_boot_cpu failed(-1) to wakeup CPU#0 # # Thomas says he knows why it's broken (my personal suspicion: our magic # handling of the "cpu0_logical_apicid" thing), but for 5.3 the right fix # is to just revert it, since we've never touched the LDR bits before, and # it's not worth the risk to do anything else at this stage. # # [ Hotpluging of the boot CPU is special anyway, and should be off by # default. See the "BOOTPARAM_HOTPLUG_CPU0" config option and the # cpu0_hotplug kernel parameter. # # In general you should not do it, and it has various known limitations # (hibernate and suspend require the boot CPU, for example). # # But it should work, even if the boot CPU is special and needs careful # treatment - Linus ] # # Link: https://lore.kernel.org/lkml/156785100521.13300.14461504732265570003@skylake-alporthouse-com/ # Reported-by: Chris Wilson <chris@chris-wilson.co.uk> # Acked-by: Thomas Gleixner <tglx@linutronix.de> # Cc: Bandan Das <bsd@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 950b07c14e8c59444e2359f15fd70ed5112e11a0 # < make -s -j 120 ARCH=sh O=/kisskb/build/linus_se7343_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- se7343_defconfig # make -s -j 120 ARCH=sh O=/kisskb/build/linus_se7343_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:385: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:388: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here /kisskb/src/drivers/sh/clk/cpg.c: In function 'r8': /kisskb/src/drivers/sh/clk/cpg.c:41:2: warning: passing argument 1 of 'ioread8' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:29:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r16': /kisskb/src/drivers/sh/clk/cpg.c:46:2: warning: passing argument 1 of 'ioread16' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:30:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r32': /kisskb/src/drivers/sh/clk/cpg.c:51:2: warning: passing argument 1 of 'ioread32' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:32:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:613:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] Kernel: arch/sh/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_se7343_defconfig_sh4 # Build took: 0:00:21.571402
