2011-11-02mfd: Fix missing abx500 header file updatesLinus Walleij1-1/+1
I missed to include a patch adding the new silicon revision define CUT3P3 and remove the retired CUT0 versions of AB8500. Also delete the reference to the retired AB3550 from the header.

2011-11-02target: add back error handling in transport_complete_taskChristoph Hellwig1-1/+5
The commit target: use a workqueue for I/O completions accidentally removed setting t_tasks_failed in transport_complete_task. Add it back in a slightly cleaner way; now it is set for every failed task instead of special casing the last one completing by using the success argument directly for it.

2011-11-02target/pscsi: blk_make_request() returns an ERR_PTR()Dan Carpenter1-1/+1
The check is wrong here because blk_make_request() returns an ERR_PTR() and it doesn't return NULL. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Nicholas A. Bellinger <nab@linux-iscsi.org>
2011-11-02target: Remove core TRANSPORT_FREE_CMD_INTR usageNicholas Bellinger4-22/+0
This patch drops TRANSPORT_FREE_CMD_INTR usage from target core, which includes the removal of transport_generic_free_cmd_intr() symbol, TRANSPORT_FREE_CMD_INTR usage in transport_processing_thread(), and special case LUN_RESET handling to skip TRANSPORT_FREE_CMD_INTR processing in core_tmr_drain_cmd_list(). We now expect that fabric modules will use an internal workqueue to provide process context when releasing se_cmd descriptor resources via transport_generic_free_cmd().

2011-11-02target: Make TFO->check_stop_free return free statusNicholas Bellinger5-8/+16
This patch converts target_core_fabric_ops->check_stop_free() usage in transport_cmd_check_stop() and associated fabric module usage to return '1' when the passed se_cmd has been released directly within ->check_stop_free(), or return '0' when the passed se_cmd has not been released. This addresses an issue where transport_cmd_finish_abort() -> transport_cmd_check_stop_to_fabric() was leaking descriptors during LUN_RESET for modules using ->check_stop_free(), but not directly releasing se_cmd in all cases.

2011-11-02iscsi-target: Fix non-immediate TMR handlingNicholas Bellinger1-4/+3
This patch addresses two issues with non immediate TMR handling in iscsit_handle_task_mgt_cmd(). The first involves breakage due to v3.1-rc conversion of iscsit_sequence_cmd(), which upon good status would hit the iscsit_add_reject_from_cmd() block of code. This patch adds an explict check for CMDSN_ERROR_CANNOT_RECOVER. The second adds a check to return when non immediate TMR operation is detected after iscsit_ack_from_expstatsn(), as iscsit_sequence_cmd() -> iscsit_execute_cmd() will have called transport_generic_handle_tmr() for the non immediate TMR case already.

2011-11-02iscsi-target: Add missing CMDSN_LOWER_THAN_EXP check in iscsit_handle_scsi_cmdNicholas Bellinger1-1/+3
This patch adds a missing CMDSN_LOWER_THAN_EXP return check for iscsit_sequence_cmd() in iscsit_handle_scsi_cmd() that was incorrectly dropped during the v3.1-rc cleanups to use iscsit_sequence_cmd().

2011-11-02target: Avoid double list_del for aborted se_tmr_reqJoern Engel1-1/+1
After the list_del() in core_tmr_drain_tmr_list(), core_tmr_release_req() would list_del() the same object again. Call graph: core_tmr_drain_tmr_list transport_cmd_finish_abort_tmr transport_generic_remove transport_free_se_cmd core_tmr_release_req So use list_del_init(), as list_del() of an initialized list_head is safe and essentially a nop. In the CONFIG_DEBUG_LIST case, list_del() actually poisons the list_head, but that is fine as we free the object directly afterwards.

2011-11-02perf top tui: Don't recalc column widths considering just the first pageArnaldo Carvalho de Melo1-1/+0
It makes sense for the stdio where we can't navigate to the other pages. On the TUI it breaks as soon as we navigate to other pages that have, DSOs with longer names than the ones on the first page.

2011-11-02perf hists browser: Warn about lost eventsArnaldo Carvalho de Melo7-29/+112
Just like the old perf top --tui and the --stdio version. But because we have the initial menu to choose which event to show in a session with multiple events we can see how many chunks were lost in each of the event types, clarifying which events are being affected the most.

2011-11-02um: fix ubd cow sizeRichard Weinberger1-1/+30
ubd_file_size() cannot use ubd_dev->cow.file because at this time ubd_dev->cow.file is not initialized. Therefore, ubd_file_size() will always report a wrong disk size when COW files are used. Reading from /dev/ubd* would crash the kernel. We have to read the correct disk size from the COW file's backing file. Signed-off-by: Richard Weinberger <richard@nod.at> CC: stable@kernel.org

it's x86-only and we have no business playing with it in asm/mmu.h; make the latter have struct uml_arch_mm_context arch; instead of struct uml_ldt ldt; and let arch/<subarch>/um/asm/mm_context.h decide what'll be in there. While we are at it, kill host_ldt.h - it's not needed in part of places that include it (we want asm/ldt.h in those) and it can be trivially expanded into the single remaining one.
