I don't have a # benchmark for this change, but huge vmap will be used by a later core # kernel change to enable huge vmalloc memory mappings. This improves # cached `git diff` performance by about 5% on a 2-node POWER9 with 32MB # size dentry cache hash. # # Profiling git diff dTLB misses with a vanilla kernel: # # 81.75% git [kernel.vmlinux] [k] __d_lookup_rcu # 7.21% git [kernel.vmlinux] [k] strncpy_from_user # 1.77% git [kernel.vmlinux] [k] find_get_entry # 1.59% git [kernel.vmlinux] [k] kmem_cache_free # # 40,168 dTLB-miss # 0.100342754 seconds time elapsed # # With powerpc huge vmalloc: # # 2,987 dTLB-miss # 0.095933138 seconds time elapsed # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 86de312343c4b56d699f8ed98aac8bdab1e94225 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1658:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg;
