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 # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 8f0c636b05429d3a83993074c35fce62eb9856ef # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:223:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
