Hence there is a high chance that # we can return without restoring the AMR value. This also helps the case # when applications are not using the pkey feature. In this case, different # applications will have the same AMR values and hence we can avoid restoring # AMR in this case too. # # Also avoid isync() if not really needed. # # Do the same for IAMR. # # null-syscall benchmark results: # # With smap/smep disabled: # Without patch: # 957.95 ns 2778.17 cycles # With patch: # 858.38 ns 2489.30 cycles # # With smap/smep enabled: # Without patch: # 1017.26 ns 2950.36 cycles # With patch: # 1021.51 ns 2962.44 cycles # # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200827040931.297759-24-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 49c7f0bdba27e02d44014e07d9d7723058b7b876 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0xf1adc4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x1000000) Image Name: Linux-5.9.0-rc2-48256-g49c7f0bdb Created: Fri Sep 11 05:01:46 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 7064465 Bytes = 6898.89 KiB = 6.74 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc9 # Build took: 0:02:32.765558
