The main goal is to avoid # the cli/sti of iopl by effectively implementing the IO port access # parts of iopl in terms of ioperm. # # This may end up not workign well in case people actually depend on # cli/sti being available, or if there are mixed uses of iopl and # ioperm. We will see.. - Linus ] # # * 'x86-iopl-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (22 commits) # x86/ioperm: Fix use of deprecated config option # x86/entry/32: Clarify register saving in __switch_to_asm() # selftests/x86/iopl: Extend test to cover IOPL emulation # x86/ioperm: Extend IOPL config to control ioperm() as well # x86/iopl: Remove legacy IOPL option # x86/iopl: Restrict iopl() permission scope # x86/iopl: Fixup misleading comment # selftests/x86/ioperm: Extend testing so the shared bitmap is exercised # x86/ioperm: Share I/O bitmap if identical # x86/ioperm: Remove bitmap if all permissions dropped # x86/ioperm: Move TSS bitmap update to exit to user work # x86/ioperm: Add bitmap sequence number # x86/ioperm: Move iobitmap data into a struct # x86/tss: Move I/O bitmap data into a seperate struct # x86/io: Speedup schedule out of I/O bitmap user # x86/ioperm: Avoid bitmap allocation if no permissions are set # x86/ioperm: Simplify first ioperm() invocation logic # x86/iopl: Cleanup include maze # x86/tss: Fix and move VMX BUILD_BUG_ON() # x86/cpu: Unify cpu_init() # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 ab851d49f6bfc781edd8bd44c72ec1e49211670b # < make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- defconfig # make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- FIT description: Linux 5.4.0-gab851d49f6bf Created: Wed Nov 27 07:40:06 2019 Image 0 (kernel@0) Description: Linux 5.4.0-gab851d49f6bf Created: Wed Nov 27 07:40:06 2019 Type: Kernel Image Compression: gzip compressed Data Size: 4766510 Bytes = 4654.79 KiB = 4.55 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x808cfad0 Hash algo: sha1 Hash value: 3f6e6dd7f6393777b118f2d6581ad6d4f5d194b5 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Wed Nov 27 07:40:06 2019 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: Wed Nov 27 07:40:06 2019 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: Wed Nov 27 07:40:06 2019 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: Wed Nov 27 07:40:06 2019 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: Wed Nov 27 07:40:06 2019 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-gcc8 # Build took: 0:01:12.217879
