The function adpt_i2o_post_wait is called from several places, in some of which, such as adpt_abort, a lock may be held. The functions adpt_i2o_reparse_lct and adpt_i2o_lct_get are called from several places, including adpt_rescan where a lock may be held. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @gfp exists@ identifier fn; position p; @@ fn(...) { ... when != spin_unlock_irqrestore when any GFP_KERNEL@p ... when any } @locked@ identifier gfp.fn; @@ spin_lock_irqsave(...) ... when != spin_unlock_irqrestore fn(...) @depends on locked@ position gfp.p; @@ - GFP_KERNEL@p + GFP_ATOMIC // </smpl> Signed-off-by:

Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable. Signed-off-by:

* hold the hardware_lock throughout the duration of ctx-sp timeout handling -- could result in use-after-free oops. * retry a timed-out login-request. * done() routines are called with the hardware-lock held, issue qla2x00_mark_device_lost() with proper 'defer' flag. * FCP2 capabilities are only relevant to target devices.

The TMFs used for pre-24xx ISPs incorrectly assumed 'cpu' tag data could be valid. These chips have no multi-q/cpu-affinity support. This corrects an oops seen on ISP23xx parts. Signed-off-by:

We have 32 (MAXSGENTRIES) scatter gather elements embedded in the command. With all these, the total command size is about 576 bytes. However, the last entry in the block fetch table is 35. (the block fetch table contains the number of 16-byte chunks the firmware needs to fetch for a given number of scatter gather elements.) 35 * 16 = 560 bytes, which isn't enough. It needs to be 36. (36 * 16 == 576) or, MAXSGENTRIES + 4. (plus 4 because there's a bunch of stuff at the front of the command before the first scatter gather element that takes up 4 * 16 bytes.) Without this fix, the controller may have to perform two DMA operations to fetch the command since the first one may not get the whole thing. Signed-off-by:
