These delays # were due to the emulation of certain MMIO operations controlling # memory layout, which were emulated with one expedited grace period per # access. Common configurations required thousands of boot-time MMIO # accesses, and thus thousands of boot-time expedited SRCU grace # periods. # # In these configurations, the occasional sleeps that allowed KLP to # proceed caused excessive boot delays. These commits preserve enough # sleeps to permit KLP to proceed, but few enough that the virtual # embedded kernels still boot reasonably quickly. # # This represents a regression introduced in the v5.19 merge window, and # the bug is causing significant inconvenience" # # * tag 'rcu-urgent.2022.07.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: # srcu: Make expedited RCU grace periods block even less frequently # srcu: Block less aggressively for expedited grace periods # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 4ba1329cbb9456c937bff1ed8ad4ca91ab75eab6 # < make -s -j 120 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 120 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 120 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 120 ARCH=sh O=/kisskb/build/linus_sh-allmodconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/machvec.c: In function 'sh_mv_setup': /kisskb/src/arch/sh/kernel/machvec.c:105:33: error: array subscript 'struct sh_machine_vector[0]' is partly outside array bounds of 'long int[1]' [-Werror=array-bounds] 105 | sh_mv = *(struct sh_machine_vector *)&__machvec_start; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /kisskb/src/arch/sh/kernel/machvec.c:13: /kisskb/src/arch/sh/include/asm/sections.h:7:13: note: while referencing '__machvec_start' 7 | extern long __machvec_start, __machvec_end; | ^~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[3]: *** [/kisskb/src/scripts/Makefile.build:249: arch/sh/kernel/machvec.o] Error 1 make[3]: *** Waiting for unfinished jobs....
