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/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 c14cab2688d09b851349acbb83e5fce8e0d4ca42 # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- FIT description: Linux 5.7.0-rc4-gc14cab2688d0 Created: Mon May 11 10:01:31 2020 Image 0 (kernel@0) Description: Linux 5.7.0-rc4-gc14cab2688d0 Created: Mon May 11 10:01:31 2020 Type: Kernel Image Compression: gzip compressed Data Size: 4950227 Bytes = 4834.21 KiB = 4.72 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x809161a0 Hash algo: sha1 Hash value: d07223a7ca27054a1cfc0db9ae939e001e76a8df Image 1 (fdt@boston) Description: img,boston Device Tree Created: Mon May 11 10:01:31 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Mon May 11 10:01:31 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Mon May 11 10:01:31 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 4639 Bytes = 4.53 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 018897896b42c41c943aca35a20e4300dba250c8 Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Mon May 11 10:01:31 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 5198 Bytes = 5.08 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 36c7bd0bd79cfc2f7dd6acda6c7996294f4967e6 Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Mon May 11 10:01:31 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/linus_mips-defconfig_mips-gcc4.9 # Build took: 0:03:27.403342
