It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue.

2011-11-04IB/iser: DMA unmap TX bufs used for iSCSI/iSER headersOr Gerlitz2-4/+8
The current driver never does DMA unmapping on these buffers.

2011-11-04IB/iser: Use separate buffers for the login request/responseOr Gerlitz3-15/+52
The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each.

2011-11-05ARM: mach-shmobile: SDHI0 GPIO hotplug for AG5EVMMagnus Damm1-0/+19
Implement GPIO hotplugging via TMIO_MMC_HAS_COLD_CD for AG5EVM SDHI0. This is possible now when INTCA is used for IRQ triggering on sh73a0. Without INTCA IRQ support we are left with the GIC hardware block that does not support dealing with active low interrupt sources.

2011-11-05ARM: mach-shmobile: Use common INTC IRQ code on sh73a0Magnus Damm2-33/+157
Improve IRQ triggering support by making use of the macro INTC_IRQ_PINS_32() for INTCA on sh73a0. Unfortunately it is not as easy as just using the macro as-is, we need to do mask and unmaks in the GIC but configure other bits and ack in INTCA. Update GPIO IRQ mappings while at it.

This patch adds support for sh73a0 GPIO IRQs by making use of the PFC GPIO IRQ feature. Only IRQ pins are supported at this time. In the future when PINT interrupts also are supported properly we can easily extend the table with such information. Also, the sh73a0 is currently making use of the GIC for external interrupt which is rather unflexible when it comes to triggering configuration at this point.

Always use CS0 shadow area for NOR flash instead of regular CS0 memory area on ap4evb. When booting from CS0 NOR Flash the regular CS0 memory area is available, but when booting via USB the MASK ROM gets mapped to 0x0 which gets in the way for the NOR Flash.

2011-11-04target: Add generic active I/O shutdown logicNicholas Bellinger4-6/+145
This patch adds the initial pieces of generic active I/O shutdown logic. This is intended to be a 'opt-in' feature for fabric modules that includes the following functions to provide a mechinism for fabric modules to track se_cmd via se_session->sess_cmd_list: *) target_get_sess_cmd() - Add se_cmd to sess->sess_cmd_list, called from fabric module incoming I/O path. *) target_put_sess_cmd() - Check for completion or drop se_cmd from ->sess_cmd_list *) target_splice_sess_cmd_list() - Splice active I/O list from ->sess_cmd_list to ->sess_wait_list, can called with HW fabric lock held. *) target_wait_for_sess_cmds() - Walk ->sess_wait_list waiting on individual ->cmd_wait_comp. Optional transport_wait_for_tasks() call. target_splice_sess_cmd_list() is allowed to be called under HW fabric lock, and performs the splice into se_sess->sess_wait_list and set se_cmd->cmd_wait_set. Then target_wait_for_sess_cmds() walks the list waiting for individual target_put_sess_cmd() fabric callbacks to complete. It also adds TFO->check_release_cmd() to split the completion and memory release calls, where a fabric module uses target_put_sess_cmd() to check for I/O completion during session shutdown. This is currently pushed out into fabric modules as current fabric code may sleep here waiting for TFO->check_stop_free() to complete in main response path, and because target_wait_for_sess_cmds() calling TFO->release_cmd() to free fabric descriptor memory directly.

Reorder parms of cifs_lock_init, trivially simplify getlk code and remove extra {} in cifs_lock_add_if. Cc: Dan Carpenter <[email protected]> Acked-by: Jeff Layton <[email protected]> Signed-off-by: Pavel Shilovsky <[email protected]> Signed-off-by: Steve French <[email protected]>
2011-11-04CIFS: Simplify setlk error handling for mandatory lockingPavel Shilovsky1-32/+32
Now we allocate a lock structure at first, then we request to the server and save the lock if server returned OK though void function - it prevents the situation when we locked a file on the server and then return -ENOMEM from setlk.

The patch adds an empty function for non-dt build, so that drivers migrating to dt can save some '#ifdef CONFIG_OF'. v3: New patch Signed-off-by: Stephen Warren <[email protected]> Signed-off-by: Grant Likely <[email protected]>
