* powerpc/pseries: Correct builds break when CONFIG_SMP not definedNathan Fontenot2013-04-30
| | | | | | | | | | | | | | | | | | | Correct build failure for powerpc/pseries builds with CONFIG_SMP not defined. The function cpu_sibling_mask has no meaning (or definition) when CONFIG_SMP is not defined. Additionally, the updating of NUMA affinity for a CPU in a UP system doesn't really make sense. This patch ifdef's out the code making the affinity updates for PRRN events to fix the following build break. arch/powerpc/mm/numa.c: In function ‘stage_topology_update’: arch/powerpc/mm/numa.c:1535: error: implicit declaration of function ‘cpu_sibling_mask’ arch/powerpc/mm/numa.c:1535: warning: passing argument 3 of ‘cpumask_or’ makes pointer from integer without a cast make[1]: *** [arch/powerpc/mm/numa.o] Error 1 Signed-off-by: Nathan Fontenot <nfont@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* powerpc/rtas_flash: Fix bad memory accessVasant Hegde2013-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use kmem_cache_alloc() to allocate memory to hold the new firmware which will be flashed. kmem_cache_alloc() calls rtas_block_ctor() to set memory to NULL. But these constructor is called only for newly allocated slabs. If we run below command multiple time without rebooting, allocator may allocate memory from the area which was free'd by kmem_cache_free and it will not call constructor. In this situation we may hit kernel oops. dd if=<fw image> of=/proc/ppc64/rtas/firmware_flash bs=4096 oops message: ------------- [ 1602.399755] Oops: Kernel access of bad area, sig: 11 [#1] [ 1602.399772] SMP NR_CPUS=1024 NUMA pSeries [ 1602.399779] Modules linked in: rtas_flash nfsd lockd auth_rpcgss nfs_acl sunrpc fuse loop dm_mod sg ipv6 ses enclosure ehea ehci_pci ohci_hcd ehci_hcd usbcore sd_mod usb_common crc_t10dif scsi_dh_alua scsi_dh_emc scsi_dh_hp_sw scsi_dh_rdac scsi_dh ipr libata scsi_mod [ 1602.399817] NIP: d00000000a170b9c LR: d00000000a170b64 CTR: c00000000079cd58 [ 1602.399823] REGS: c0000003b9937930 TRAP: 0300 Not tainted (3.9.0-rc4-0.27-ppc64) [ 1602.399828] MSR: 8000000000009032 <SF,EE,ME,IR,DR,RI> CR: 22000428 XER: 20000000 [ 1602.399841] SOFTE: 1 [ 1602.399844] CFAR: c000000000005f24 [ 1602.399848] DAR: 8c2625a820631fef, DSISR: 40000000 [ 1602.399852] TASK = c0000003b4520760[3655] 'dd' THREAD: c0000003b9934000 CPU: 3 GPR00: 8c2625a820631fe7 c0000003b9937bb0 d00000000a179f28 d00000000a171f08 GPR04: 0000000010040000 0000000000001000 c0000003b9937df0 c0000003b5fb2080 GPR08: c0000003b58f7200 d00000000a179f28 c0000003b40058d4 c00000000079cd58 GPR12: d00000000a171450 c000000007f40900 0000000000000005 0000000010178d20 GPR16: 00000000100cb9d8 000000000000001d 0000000000000000 000000001003ffff GPR20: 0000000000000001 0000000000000000 00003fffa0b50d30 000000001001f010 GPR24: 0000000010020888 0000000010040000 d00000000a171f08 d00000000a172808 GPR28: 0000000000001000 0000000010040000 c0000003b4005880 8c2625a820631fe7 [ 1602.399924] NIP [d00000000a170b9c] .rtas_flash_write+0x7c/0x1e8 [rtas_flash] [ 1602.399930] LR [d00000000a170b64] .rtas_flash_write+0x44/0x1e8 [rtas_flash] [ 1602.399934] Call Trace: [ 1602.399939] [c0000003b9937bb0] [d00000000a170b64] .rtas_flash_write+0x44/0x1e8 [rtas_flash] (unreliable) [ 1602.399948] [c0000003b9937c60] [c000000000282830] .proc_reg_write+0x90/0xe0 [ 1602.399955] [c0000003b9937ce0] [c0000000001ff374] .vfs_write+0x114/0x238 [ 1602.399961] [c0000003b9937d80] [c0000000001ff5d8] .SyS_write+0x70/0xe8 [ 1602.399968] [c0000003b9937e30] [c000000000009cdc] syscall_exit+0x0/0xa0 [ 1602.399973] Instruction dump: [ 1602.399977] eb698010 801b0028 2f80dcd6 419e00a4 2fbc0000 419e009c ebfb0030 2fbf0000 [ 1602.399989] 409e0010 480000d8 60000000 7c1f0378 <e81f0008> 2fa00000 409efff4 e81f0000 [ 1602.400012] ---[ end trace b4136d115dc31dac ]--- [ 1602.402178] [ 1602.402185] Sending IPI to other CPUs [ 1602.403329] IPI complete This patch uses kmem_cache_zalloc() instead of kmem_cache_alloc() to allocate memory, which makes sure memory is set to 0 before using.

| | | | | | | | | | | | | | | | | | | | | | The reg property in the pci bridge device node is used to bind this device node to the pci bridge device. Then all the pci devices under this bridge could use the interrupt maps defined in this device node to do the irq translation. So if this property is missed, the pci traditional irq mechanism will not work. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
