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 usable 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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < git log --format=%s --max-count=1 9ef34630a4614ee1cd478f9859ebea55d55f10ec # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- arch/mips/boot/dts/xilfpga/nexys4ddr.dtb: Warning (i2c_bus_reg): /i2c@10A00000/ad7420@4B: I2C bus unit address format error, expected "4b" FIT description: Linux 4.20.0-rc1-g9ef34630a461 Created: Sun Dec 9 21:44:08 2018 Image 0 (kernel@0) Description: Linux 4.20.0-rc1-g9ef34630a461 Created: Sun Dec 9 21:44:08 2018 Type: Kernel Image Compression: gzip compressed Data Size: 4505283 Bytes = 4399.69 KiB = 4.30 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x8085c250 Hash algo: sha1 Hash value: d15751769145bf3b24feb8ff0b7ceb6e8cce8258 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Sun Dec 9 21:44:08 2018 Type: Flat Device Tree Compression: uncompressed Data Size: 3668 Bytes = 3.58 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 569c37cc891ce1e1f3a193cb41cc691a5d2debb5 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Sun Dec 9 21:44:08 2018 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Sun Dec 9 21:44:08 2018 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 509ce58e44c561d54539e64e9d4b47054e696fc6 Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/powerpc-fixes_mips-defconfig_mipsel # Build took: 0:01:44.239511
