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/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 8f0c636b05429d3a83993074c35fce62eb9856ef # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_iss476-smp_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/iss476-smp_defconfig WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_iss476-smp_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:148:32: warning: 'levelspread[<U 780>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:96:6: note: 'levelspread[<U 780>]' was declared here /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/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x5dd110) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5dd110) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Completed OK # rm -rf /kisskb/build/powerpc-next_44x_iss476-smp_defconfig_powerpc # Build took: 0:00:50.229655
