It is going to be a\n bit more nasty than usual as in touching things outside of\n arch/powerpc mostly due to the big iSeriesectomy :-) We finally got\n rid of the bugger (legacy iSeries support) which was a PITA to\n maintain and that nobody really used anymore.\n\n Here are some of the highlights:\n\n - Legacy iSeries is gone. Thanks Stephen ! There\u0027s still some bits\n and pieces remaining if you do a grep -ir series arch/powerpc but\n they are harmless and will be removed in the next few weeks\n hopefully.\n\n - The \u0027fadump\u0027 functionality (Firmware Assisted Dump) replaces the\n previous (equivalent) \"pHyp assisted dump\"... it\u0027s a rewrite of a\n mechanism to get the hypervisor to do crash dumps on pSeries, the\n new implementation hopefully being much more reliable. Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there. Note that this adds a field to struct device_node which is\n not very nice and which Grant objects to. I will have a patch soon\n that moves that to a powerpc private data structure (hopefully\n before rc1) and we\u0027ll improve things further later on (hopefully\n getting rid of the need for that pointer completely). Thanks Gavin\n Shan.\n\n - I dug into our exception \u0026 interrupt handling code to improve the\n way we do lazy interrupt handling (and make it work properly with\n \"edge\" triggered interrupt sources), and while at it found \u0026 fixed\n a wagon of issues in those areas, including adding support for page\n fault retry \u0026 fatal signals on page faults.\n\n - Your usual random batch of small fixes \u0026 updates, including a bunch\n of new embedded boards, both Freescale and APM based ones, etc...\"\n\nI fixed up some conflicts with the generalized irq-domain changes from\nGrant

But now they\nare actually 20 bit. So the fix is simplicity itself.\n\nI\u0027ve tested with 300 devices and all user-mode utils\nwork just fine. I have also mechanically added 10,000\nto the ida (so devices are /dev/osd10000, /dev/osd10001 ...)\nand was able to mkfs an exofs filesystem and access osds\nfrom user-mode.\n\nAll the open-osd user-mode code uses the same library\nto access devices through their symbolic names in\n/dev/osdX so I\u0027d say it\u0027s pretty safe. (Well tested)\n\nThis patch is very important because some of the systems\nthat will be deploying the 3.2 pnfs-objects code are larger\nthan 64 OSDs and will stop to work properly when reaching\nthat number.\n\nCC: Stable \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "16bca1d572930e5b91714d2c79ec986bc819e7a6", "tree": "08f11baf62bc5c13d0a9202c926f8c4e18de6441", "parents": [ "e98092bedcfff1908ad7a32acc46f13e4d8b2f43", "3569e5374df66a42ab66368b8bbb075e81d4e85c" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Feb 24 16:08:51 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Feb 24 16:08:51 2012 -0800" }, "message": "Merge tag \u0027scsi-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6\n\nSCSI fixes on 20120224:\n \"This is a set of assorted bug fixes for power management, mpt2sas,\n ipr, the rdac device handler and quite a big chunk for qla2xxx (plus a\n use after free of scsi_host in scsi_scan.c). \"\n\n* tag \u0027scsi-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6:\n [SCSI] scsi_dh_rdac: Fix for unbalanced reference count\n [SCSI] scsi_pm: Fix bug in the SCSI power management handler\n [SCSI] scsi_scan: Fix \u0027Poison overwritten\u0027 warning caused by using freed \u0027shost\u0027\n [SCSI] qla2xxx: Update version number to 8.03.07.13-k.\n [SCSI] qla2xxx: Proper detection of firmware abort error code for ISP82xx.\n [SCSI] qla2xxx: Remove resetting memory during device initialization for ISP82xx.\n [SCSI] qla2xxx: Complete mailbox command timedout to avoid initialization failures during next reset cycle.\n [SCSI] qla2xxx: Remove check for null fcport from host reset handler.\n [SCSI] qla2xxx: Correct out of bounds read of ISP2200 mailbox registers.\n [SCSI] qla2xxx: Remove errant clearing of MBX_INTERRUPT flag during CT-IOCB processing.\n [SCSI] qla2xxx: Clear options-flags while issuing stop-firmware mbx command.\n [SCSI] qla2xxx: Add an \"is reset active\" helper.\n [SCSI] qla2xxx: Add check for null fcport references in qla2xxx_queuecommand.\n [SCSI] qla2xxx: Propagate up abort failures.\n [SCSI] isci: Fix NULL ptr dereference when no firmware is being loaded\n [SCSI] ipr: fix eeh recovery for 64-bit adapters\n [SCSI] mpt2sas: Fix mismatch in mpt2sas_base_hard_reset_handler() mutex lock-unlock\n" }, { "commit": "c69263c66e5b2a5d0c7e5a41c189b1846ae1de92", "tree": "81c6cf0f5b3b05739e2e73b0118077d9dd245182", "parents": [ "45196cee28a5bcfb6ddbe2bffa4270cbed66ae4b", "5407a3c3d942e75d4d123d213fd692bce5acc961" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Feb 23 08:20:44 2012 -0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Feb 23 08:21:03 2012 -0800" }, "message": "Merge branch \u0027usb-3.3-rc4\u0027 into usb-next\n\nThis is to pull in the xhci changes and the other fixes and device id\nupdates that were done in Linus\u0027s tree.\n\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "3569e5374df66a42ab66368b8bbb075e81d4e85c", "tree": "dadcf03a1949b5918c286ba6d43da1ef9ece68a1", "parents": [ "fea6d607e154cf96ab22254ccb48addfd43d4cb5" ], "author": { "name": "Moger, Babu", "email": "Babu.Moger@netapp.com", "time": "Thu Feb 02 15:21:54 2012 +0000" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Wed Feb 22 12:15:19 2012 -0600" }, "message": "[SCSI] scsi_dh_rdac: Fix for unbalanced reference count\n\nThis patch fixes an unbalanced refcount issue.\n\nElevating the lock for both kref_put and also for controller node deletion.\nPreviously, controller deletion was protected but the not the kref_put.
