A single larx/stcx. works fine, no need for the less # efficient cmpxchg sequence. # # Then remove the memory barriers from the operation. There is a # requirement for TLB flushing to load mm_cpumask after the store # that reduces pte permissions, which is moved into the TLB flush # code. # # Signed-off-by: Nicholas Piggin # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 c8635bc26fc137c218cba3b48a834a667e3ac790 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0xc3d10c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xd00000) Image Name: Linux-4.17.0-rc3-gc8635bc Created: Thu May 24 00:38:58 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 5837895 Bytes = 5701.07 kB = 5.57 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-5.3 # Build took: 0:01:54.988861
