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 <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190917123851.22553-1-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 c145ff82749b4daa660ab4739f5412b2d62e2d8a # < make -s -j 24 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 24 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: 0:05:22.938245
