2010-07-27[SCSI] ipr: add endian swap enablement for 64 bit adaptersWayne Boyer
A change in the hardware design of the chip for the new adapters changes the default endianness of MMIO operations. This patch adds a register definition which when written to with a predefined value will change the endianness back to what the driver expects. This patch also fixes two problems found during testing. First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only reserved one byte. The correct amount to reserve is 2 bytes. Second, the reserved field of the ipr_hostrcb64_error structure only reserved 2 bytes. The correct amount to reserve is 16 bytes.

2010-07-27[SCSI] dpt_i2o: Use GFP_ATOMIC when a lock is heldJulia Lawall
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: Julia Lawall <julia@diku.dk> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

2010-07-27[SCSI] qla2xxx: Handle outstanding mbx cmds on hung f/w scenarios.Santosh Vernekar
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.

2010-07-27[SCSI] hpsa: fix block fetch table problem.Stephen M. Cameron
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.
