If GART got an address that a device\ncan\u0027t access to, GART mapped the address to a virtual I/O address. But\nGART mapping mechanism didn\u0027t take account of dma mask, so GART could\nuse a virtual I/O address that the device can\u0027t access to again.\n\nAlan pointed out:\n\n\" This is indeed a specific problem found with things like older\n AACRAID where control blocks must be below 31bits and the GART\n is above 0x80000000. \"\n\nThe above commit modified GART mapping mechanism to take care of dma\nmask. But Andi pointed out, \"The GART is somewhere in the 4GB range so\nyou cannot use it to map anything \u003c 4GB. Also GART is pretty small.\"\n\nhttp://lkml.org/lkml/2008/9/12/43\n\nThat means it\u0027s possible that GART doesn\u0027t have virtual I/O address\nspace that a device can access to. The above commit (to modify GART\nmapping mechanism to take care of dma mask) can\u0027t fix the regression\nreliably so let\u0027s avoid making GART more complicated.\n\nWe need a solution that always works for dma_masks \u003e 24bit \u003c\n32bits. That\u0027s how GART worked before the alloc_coherent rewrite.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nAcked-by: Joerg Roedel \u003cjoerg.roedel@amd.com\u003e\nAcked-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "9f6ac57729724b58df81ca5dc005326759a806fe", "tree": "d9ee77c4518d83582bf1de1acf43e1834932f5f3", "parents": [ "afa9fdc2f5f8e4d98f3e77bfa204412cbc181346" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Wed Sep 24 20:48:35 2008 +0900" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Sep 25 11:02:25 2008 +0200" }, "message": "x86: export pci-nommu\u0027s alloc_coherent\n\nThis patch exports nommu_alloc_coherent (renamed\ndma_generic_alloc_coherent).

This is in contrast to settings\nthe link policy on every connection setup. Using the default link policy\nis the preferred way since there is no need to dynamically change it for\nevery connection.\n\nFor backward compatibility reason and to support old userspace the\nHCISETLINKPOL ioctl has been switched over to using hci_request() to\nissue the HCI command for setting the default link policy instead of\njust storing it in the HCI device structure.\n\nHowever the hci_request() can only be issued when the device is\nbrought up. If used on a device that is registered, but still down\nit will timeout and fail. This is problematic since the command is\nput on the TX queue and the Bluetooth core tries to submit it to\nhardware that is not ready yet. The timeout for these requests is\n10 seconds and this causes a significant regression when setting up\na new device.\n\nThe userspace can perfectly handle a failure of the HCISETLINKPOL\nioctl and will re-submit it later, but the 10 seconds delay causes\na problem. So in case hci_request() is called on a device that is\nstill down, just fail it with ENETDOWN to indicate what happens.\n\nSigned-off-by: Marcel Holtmann \u003cmarcel@holtmann.org\u003e\n" }, { "commit": "a551b98d5f6fce5897d497abd8bfb262efb33d2a", "tree": "60634dfa4e501486ac6f948fca57aeff49cb9aa0", "parents": [ "d1c6d2e547148c5aa0c0a4ff6aac82f7c6da1d8b", "50bed2e2862a8f3a4f7d683d0d27292e71ef18b9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 11 11:50:15 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 11 11:50:15 2008 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block\n\n* \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block:\n sg: disable interrupts inside sg_copy_buffer\n" }, { "commit": "d1c6d2e547148c5aa0c0a4ff6aac82f7c6da1d8b", "tree": "1e148af6f4898465b1f7387be335734700bf9ff8", "parents": [ "6d242a263618ba7f0f9a41dd91b347d19e704bbe" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Sep 11 17:18:56 2008 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 11 10:36:08 2008 -0700" }, "message": "MN10300: Change the fault handler to check in_atomic() not in_interrupt()\n\nChange the MN10300 fault handler to make it check in_atomic() rather than\nin_interrupt() as commit 6edaf68a87d17570790fd55f0c451a29ec1d6703 did for other\narchitectures:\n\n\tAuthor: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\n\tDate: Wed Dec 6 20:32:18 2006 -0800\n\n\t[PATCH] mm: arch do_page_fault() vs in_atomic()\n\n\tIn light of the recent pagefault and filemap_copy_from_user work I\u0027ve\n\tgone through all the arch pagefault handlers to make sure the\n\tinc_preempt_count() \u0027feature\u0027 works as expected.\n\n\tSeveral sections of code (including the new filemap_copy_from_user)\n\trely on the fact that faults do not take locks under increased preempt\n\tcount.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "50bed2e2862a8f3a4f7d683d0d27292e71ef18b9", "tree": "4de32d8495a5b79aae38948871abc65bb58d9d10", "parents": [ "2dc75d3c3b49c64fd26b4832a7efb75546cb3fc5" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Thu Sep 11 18:35:39 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Sep 11 18:35:39 2008 +0200" }, "message": "sg: disable interrupts inside sg_copy_buffer\n\nThe callers of sg_copy_buffer must disable interrupts before calling\nit (since it uses kmap_atomic).
