Thus numa_nodes_parsed should be set\nby not only acpi_numa_processor_affinity_init /\nacpi_numa_x2apic_affinity_init but also\nacpi_numa_memory_affinity_init for the case.\n\nAdditionally, if system has cpuless memory node,\nacpi_numa_processor_affinity_init /\nacpi_numa_x2apic_affinity_init cannot set numa_nodes_parseds\nsince these functions cannot find cpu description for the node.\nIn this case, numa_nodes_parsed needs to be set by\nacpi_numa_memory_affinity_init.\n\nSigned-off-by: Yasuaki Ishimatsu \u003cisimatu.yasuaki@jp.fujitsu.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: liuj97@gmail.com\nCc: kosaki.motohiro@gmail.com\nLink: http://lkml.kernel.org/r/4FCC2098.4030007@jp.fujitsu.com\n[ merged it ]\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n" }, { "commit": "aff5a62d52ff03956ff6992b9fe4b561fd855804", "tree": "3ee9fbb561ca19adf2b5a8583050566bc356ab0e", "parents": [ "1a87fc1ec7b05b9bc60df9dc52297d4c225d7f1a" ], "author": { "name": "Xiaotian Feng", "email": "xtfeng@gmail.com", "time": "Tue Jun 05 15:00:31 2012 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@kernel.org", "time": "Wed Jun 06 11:58:38 2012 +0200" }, "message": "x86/gart: Fix kmemleak warning\n\naperture_64.c now is using memblock, the previous\nkmemleak_ignore() for alloc_bootmem() should be removed then.\n\nOtherwise, with kmemleak enabled, kernel will throw warnings\nlike:\n\n[ 0.000000] kmemleak: Trying to color unknown object at 0xffff8800c4000000 as Black\n[ 0.000000] Pid: 0, comm: swapper/0 Not tainted 3.5.0-rc1-next-20120605+ #130\n[ 0.000000] Call Trace:\n[ 0.000000] [\u003cffffffff811b27e6\u003e] paint_ptr+0x66/0xc0\n[ 0.000000] [\u003cffffffff816b90fb\u003e] kmemleak_ignore+0x2b/0x60\n[ 0.000000] [\u003cffffffff81ef7bc0\u003e] kmemleak_init+0x217/0x2c1\n[ 0.000000] [\u003cffffffff81ed2b97\u003e] start_kernel+0x32d/0x3eb\n[ 0.000000] [\u003cffffffff81ed25e4\u003e] ? repair_env_string+0x5a/0x5a\n[ 0.000000] [\u003cffffffff81ed2356\u003e] x86_64_start_reservations+0x131/0x135\n[ 0.000000] [\u003cffffffff81ed2120\u003e] ? early_idt_handlers+0x120/0x120\n[ 0.000000] [\u003cffffffff81ed245c\u003e] x86_64_start_kernel+0x102/0x111\n[ 0.000000] kmemleak: Early log backtrace:\n[ 0.000000] [\u003cffffffff816b911b\u003e] kmemleak_ignore+0x4b/0x60\n[ 0.000000] [\u003cffffffff81ee6a38\u003e] gart_iommu_hole_init+0x3e7/0x547\n[ 0.000000] [\u003cffffffff81edb20b\u003e] pci_iommu_alloc+0x44/0x6f\n[ 0.000000] [\u003cffffffff81ee81ad\u003e] mem_init+0x19/0xec\n[ 0.000000] [\u003cffffffff81ed2a54\u003e] start_kernel+0x1ea/0x3eb\n[ 0.000000] [\u003cffffffff81ed2356\u003e] x86_64_start_reservations+0x131/0x135\n[ 0.000000] [\u003cffffffff81ed245c\u003e] x86_64_start_kernel+0x102/0x111\n[ 0.000000] [\u003cffffffffffffffff\u003e] 0xffffffffffffffff\n\nSigned-off-by: Xiaotian Feng \u003cdannyfeng@tencent.com\u003e\nCc: Xiaotian Feng \u003cxtfeng@gmail.com\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nLink: http://lkml.kernel.org/r/1338922831-2847-1-git-send-email-xtfeng@gmail.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n" }, { "commit": "1a87fc1ec7b05b9bc60df9dc52297d4c225d7f1a", "tree": "c3193dd6008a9ec5986bcc45fb15744d9b291085", "parents": [ "958fb3c51295764599d6abce87e1a01ace897a3e" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Jun 06 11:33:21 2012 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Jun 06 11:33:21 2012 +0200" }, "message": "x86: mce: Add the dropped timer interval init back\n\ncommit 82f7af09 (\"x86/mce: Cleanup timer mess) dropped the\ninitialization of the per cpu timer interval.
