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/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 9ef34630a4614ee1cd478f9859ebea55d55f10ec # < make -s -j 120 ARCH=x86_64 O=/kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # make -s -j 120 ARCH=x86_64 O=/kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/x86/kernel/apic/io_apic.c: In function 'mp_map_pin_to_irq': /kisskb/src/arch/x86/kernel/apic/io_apic.c:1034:6: warning: 'irq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:650:16: warning: 'gapstart' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64 # Build took: 0:03:01.282087
