This is useful when adding # large amount of ZONE_DEVICE memory to a system with a limited amount of # normal memory. # # On ppc64 we use huge pages to map the vmemmap which requires the backing # storage to be contigious and aligned to the hugepage size. The altmap # implementation allows for the altmap provider to reserve a few PFNs at # the start of the range for it's own uses and when this occurs the # first chunk of the altmap is not usage for hugepage mappings. On hash # there is no sane way to fall back to a normal sized page mapping so we # fail the allocation. This results in memory hotplug failing with # ENOMEM when the new range doesn't fall into an existing vmemmap block. # # This patch handles this case by falling back to using system memory # rather than failing if we cannot allocate from the altmap. This # fallback should only ever be used for the first vmemmap block so it # should not cause excess memory consumption. # # Fixes: 7b73d978a5d0 ("mm: pass the vmem_altmap to vmemmap_populate") # Signed-off-by: Oliver O'Halloran <oohall@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 06cfdca71d0b8b58f29f9e18f8cacc1172034971 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc832x_rdb_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/mpc832x_rdb_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc832x_rdb_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/dts/mpc832x_rdb.dtb: Warning (interrupts_property): /qe@e0100000/mdio@3120/ethernet-phy@0:#interrupt-cells: size is (4), expected multiple of 8 arch/powerpc/boot/dts/mpc832x_rdb.dtb: Warning (interrupts_property): /qe@e0100000/mdio@3120/ethernet-phy@4:#interrupt-cells: size is (4), expected multiple of 8 INFO: Uncompressed kernel (size 0x5ad6f8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x59cfe0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.20.0-rc1-g06cfdca71d0b Created: Sat Dec 8 02:20:55 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2870184 Bytes = 2802.91 KiB = 2.74 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.20.0-rc1-g06cfdca71d0b Created: Sat Dec 8 02:20:55 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2899540 Bytes = 2831.58 KiB = 2.77 MiB Load Address: 00600000 Entry Point: 00600294 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_mpc832x_rdb_defconfig_powerpc-gcc5 # Build took: 0:00:25.810480
