The optimization for small ranges failed to do so # when the virtual address was in the vmalloc or module space. # # - Unbreak the trace event registration for syscalls without arguments # caused by the refactoring of the SYSCALL_DEFINE0() macro. # # - Move the printk in the TSC deadline timer code to a place where it # is guaranteed to only be called once during boot and cannot be # rearmed by clearing warn_once after boot. If it's invoked post boot # then lockdep rightfully complains about a potential deadlock as the # calling context is different. # # - A series of fixes for objtool and the ORC unwinder addressing # variety of small issues: # # - Stack offset tracking for indirect CFAs in objtool ignored # subsequent pushs and pops # # - Repair the unwind hints in the register clearing entry ASM code # # - Make the unwinding in the low level exit to usermode code stop # after switching to the trampoline stack. The unwind hint is no # longer valid and the ORC unwinder emits a warning as it can't # find the registers anymore. # # - Fix unwind hints in switch_to_asm() and rewind_stack_do_exit() # which caused objtool to generate bogus ORC data. # # - Prevent unwinder warnings when dumping the stack of a # non-current task as there is no way to be sure about the # validity because the dumped stack can be a moving target. # # - Make the ORC unwinder behave the same way as the frame pointer # unwinder when dumping an inactive tasks stack and do not skip # the first frame. # # - Prevent ORC unwinding before ORC data has been initialized # # - Immediately terminate unwinding when a unknown ORC entry type # is found. # # - Prevent premature stop of the unwinder caused by IRET frames. # # - Fix another infinite loop in objtool caused by a negative # offset which was not catched. # # - Address a few build warnings in the ORC unwinder and add # missing static/ro_after_init annotations" # # * tag 'x86-urgent-2020-05-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/unwind/orc: Move ORC sorting variables under !CONFIG_MODULES # x86/apic: Move TSC deadline timer debug printk # ftrace/x86: Fix trace event registration for syscalls without arguments # x86/mm/cpa: Flush direct map alias during cpa # objtool: Fix infinite loop in for_offset_range() # x86/unwind/orc: Fix premature unwind stoppage due to IRET frames # x86/unwind/orc: Fix error path for bad ORC entry type # x86/unwind/orc: Prevent unwinding before ORC initialization # x86/unwind/orc: Don't skip the first frame for inactive tasks # x86/unwind: Prevent false warnings for non-current tasks # x86/unwind/orc: Convert global variables to static # x86/entry/64: Fix unwind hints in rewind_stack_do_exit() # x86/entry/64: Fix unwind hints in __switch_to_asm() # x86/entry/64: Fix unwind hints in kernel exit path # x86/entry/64: Fix unwind hints in register clearing code # objtool: Fix stack offset tracking for indirect CFAs # < /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 c14cab2688d09b851349acbb83e5fce8e0d4ca42 # < make -s -j 8 ARCH=sh O=/kisskb/build/linus_sh7785lcr_defconfig_sh4-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- sh7785lcr_defconfig # < make -s -j 8 ARCH=sh O=/kisskb/build/linus_sh7785lcr_defconfig_sh4-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 8 ARCH=sh O=/kisskb/build/linus_sh7785lcr_defconfig_sh4-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 8 ARCH=sh O=/kisskb/build/linus_sh7785lcr_defconfig_sh4-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :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;
