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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 ab851d49f6bfc781edd8bd44c72ec1e49211670b # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x5417c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5417c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5417c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5417c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x531178) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.4.0-gab851d49f6bf Created: Wed Nov 27 07:06:45 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2635036 Bytes = 2573.28 KiB = 2.51 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.4.0-gab851d49f6bf Created: Wed Nov 27 07:06:45 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2669558 Bytes = 2606.99 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 006019cc Image Name: Linux-5.4.0-gab851d49f6bf Created: Wed Nov 27 07:06:45 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2668958 Bytes = 2606.40 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 00601758 Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:00:46.392949
