On architectures like ppc64 we # can map the memmap area using 16MB hugepage size and that can cover # a memory range of 16G. # # While enabling new pmem namespaces, since memory is added in sub-section chunks, # before creating a new memmap mapping, kernel should check whether there is an # existing memmap mapping covering the new pmem namespace. Currently, this is # validated by checking whether the section covering the range is already # initialized or not. Considering there can be multiple namespaces in the same # section this can result in wrong validation. Update this to check for # sub-sections in the range. This is done by checking for all pfns in the range we # are mapping. # # We could optimize this by checking only just one pfn in each sub-section. But # since this is not fast-path we keep this simple. # # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20190917123851.22553-1-aneesh.kumar@linux.ibm.com # < /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 c145ff82749b4daa660ab4739f5412b2d62e2d8a # < make -s -j 24 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 24 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- In file included from /kisskb/src/sound/ppc/pmac.h:12, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:208:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
