This patch increase the # limit to 2PB. We can have devices like nvdimm which adds memory above 512TB # limit. # # We still don't support regular system ram above 512TB. One of the challenge with # that is the percpu allocator, that allocates per node memory and use the max # distance between them as the percpu offsets. This means with large gap in # address space ( system ram above 1PB) we will run out of vmalloc space to map # the percpu allocation. # # In order to support addressable memory above 512TB, kernel should be able to # linear map this range. To do that with hash translation we now add 4 context # to kernel linear map region. Our per context addressable range is 512TB. We # still keep VMALLOC and VMEMMAP region to old size. SLB miss handlers is updated # to validate these limit. # # We also limit this update to SPARSEMEM_VMEMMAP and SPARSEMEM_EXTREME # # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.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 4ffe713b7587b14695c9bec26a000fc88ef54895 # < make -s -j 120 ARCH=x86_64 O=/kisskb/build/powerpc-next_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-next_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:185:16: warning: 'old' 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:651:16: warning: 'gapstart' 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] Completed OK # rm -rf /kisskb/build/powerpc-next_x86_64-allnoconfig_x86_64 # Build took: 0:00:23.581119
