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-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 49c7f0bdba27e02d44014e07d9d7723058b7b876 # < make -s -j 80 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # < make -s -j 80 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 80 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 80 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_s390-defconfig_s390x-gcc8 # Build took: 0:04:45.813687
