On new Intel platforms it\u0027s necessary to\ninitialize this array as well though, otherwise all PCI node numbers\nwill be 0, when in fact they should be -1 (indicating that I/O isn\u0027t\ntied to any particular node).\n\nSo move the mp_bus_to_node code into the common PCI code, and\ninitialize it early with a default value of -1. This may be overridden\nlater by arch code (e.g. the AMD code).\n\nWith this change, PCI consistent memory and other node specific\nallocations (e.g. skbuff allocs) should occur on the \"current\" node.\nIf, for performance reasons, applications want to be bound to specific\nnodes, they should open their devices only after being pinned to the\nCPU where they\u0027ll run, for maximum locality.\n\nAcked-by: Yinghai Lu \u003cyinghai@kernel.org\u003e\nTested-by: Jesse Brandeburg \u003cjesse.brandeburg@gmail.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "eaa959df299157e2640fcb3321537501b6afd9e6", "tree": "97770bd2f73d9d5d307fa9a38da8609aa71c4240", "parents": [ "852710d9fd9f2e59fcec65cc701867db4e801bc7" ], "author": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Tue Jun 30 21:45:44 2009 -0700" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Wed Sep 09 13:29:20 2009 -0700" }, "message": "PCI: export pci_claim_resource for driver use\n\nyenta needs this for example.\n\nAcked-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nReported-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "852710d9fd9f2e59fcec65cc701867db4e801bc7", "tree": "51d5e63d6f8e8a7929b020411e70a502c1cce946", "parents": [ "eae91c0215d99f7727b66e2928fb73bf86bc9668" ], "author": { "name": "Matthew Wilcox", "email": "willy@linux.intel.com", "time": "Fri Jun 19 09:36:15 2009 -0400" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Wed Sep 09 13:29:19 2009 -0700" }, "message": "yenta: Use pci_claim_resource\n\nInstead of open-coding pci_find_parent_resource and request_resource,\njust call pci_claim_resource.\n\nSigned-off-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "eae91c0215d99f7727b66e2928fb73bf86bc9668", "tree": "74335cbc810e9789384de7ff49120e4e894e7192", "parents": [ "a7db50405216610c8a0d62b8b400180b6f366733" ], "author": { "name": "Matthew Wilcox", "email": "willy@linux.intel.com", "time": "Fri Jun 19 09:36:13 2009 -0400" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Wed Sep 09 13:29:18 2009 -0700" }, "message": "frv/PCI: Use pci_claim_resource\n\nInstead of open-coding pci_find_parent_resource and request_resource,\njust call pci_claim_resource.\n\nAcked-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "a7db50405216610c8a0d62b8b400180b6f366733", "tree": "d86aeb344ce4966cf2f7b69c1ec1cd5111372545", "parents": [ "7135a71b19be1faf48b7148d77844d03bc0717d6" ], "author": { "name": "Alex Chiang", "email": "achiang@hp.com", "time": "Mon Jun 22 08:08:07 2009 -0600" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Wed Sep 09 13:29:18 2009 -0700" }, "message": "PCI: remove pcibios_scan_all_fns()\n\nThis was #define\u0027d as 0 on all platforms, so let\u0027s get rid of it.\n\nThis change makes pci_scan_slot() slightly easier to read.\n\nCc: Yoshinori Sato \u003cysato@users.sourceforge.jp\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: \"David S.
