The change also solved a similar # problem for MIPS which fortunately has time namespaces not yet # enabled. # # S390 needs to update clock related VDSO data independent of the # timekeeping updates. This was solved so far with yet another # sequence counter in the S390 implementation. A better solution is # to utilize the already existing VDSO sequence count for this. The # core code now exposes helper functions which allow to serialize # against the timekeeper code and against concurrent readers. # # S390 needs extra data for their clock readout function. The initial # common VDSO data structure did not provide a way to add that. It # now has an embedded architecture specific struct embedded which # defaults to an empty struct. # # Doing this now avoids tree dependencies and conflicts post rc1 and # allows all other architectures which work on generic VDSO support # to work from a common upstream base. # # - A trivial comment fix" # # * tag 'timers-urgent-2020-08-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # time: Delete repeated words in comments # lib/vdso: Allow to add architecture-specific vdso data # timekeeping/vsyscall: Provide vdso_update_begin/end() # vdso/treewide: Add vdso_data pointer argument to __arch_get_hw_counter() # < /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 b923f1247b72fc100b87792fd2129d026bb10e66 # < 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 KCONFIG_SEED=0x2E6D3D52 # 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 # < 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:5035:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # 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- vmlinux.o: warning: objtool: __do_fast_syscall_32()+0x57: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: do_int80_syscall_32()+0x38: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: idtentry_enter_nmi()+0x45: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: idtentry_exit_nmi()+0x2e: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: fixup_bad_iret()+0x72: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: noist_exc_debug()+0x48: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: exc_nmi()+0xb9: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: poke_int3_handler()+0x43: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: mce_check_crashing_cpu()+0x13: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: do_machine_check()+0x37: call to mce_rdmsrl() leaves .noinstr.text section vmlinux.o: warning: objtool: exc_machine_check()+0x65: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: noist_exc_machine_check()+0x6d: call to __sanitizer_cov_trace_pc() leaves .noinstr.text section vmlinux.o: warning: objtool: syscall_enter_from_user_mode()+0x26: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: syscall_exit_to_user_mode()+0x81: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: irqentry_enter_from_user_mode()+0x1c: call to ftrace_likely_update() leaves .noinstr.text section vmlinux.o: warning: objtool: irqentry_exit_to_user_mode()+0x2b: call to ftrace_likely_update() leaves .noinstr.text section Completed OK # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 # Build took: 0:09:58.703216
