scsi: fas216: fix sense buffer initialization

2018-05-31T23:30:10+00:00

commit 96d5eaa9bb74d299508d811d865c2c41b38b0301 upstream. While testing with the ARM specific memset() macro removed, I ran into a compiler warning that shows an old bug: drivers/scsi/arm/fas216.c: In function 'fas216_rq_sns_done': drivers/scsi/arm/fas216.c:2014:40: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length? [-Werror=sizeof-pointer-memaccess] It turns out that the definition of the scsi_cmd structure changed back in linux-2.6.25, so now we clear only four bytes (sizeof(pointer)) instead of 96 (SCSI_SENSE_BUFFERSIZE). I did not check whether we actually need to initialize the buffer here, but it's clear that if we do it, we should use the correct size.

SCSI: arm fas216: fix missing ';'

f281233 (SCSI host lock push-down) broke the fas216 build: drivers/scsi/arm/fas216.h: In function 'fas216_noqueue_command': drivers/scsi/arm/fas216.h:354: error: storage class specified for parameter 'fas216_intr' drivers/scsi/arm/fas216.h:356: error: storage class specified for parameter 'fas216_remove' ...

SCSI host lock push-down

2010-11-16T21:33:23+00:00

Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

[ARM] dma: Use sensible DMA parameters for Acorn drivers

2008-12-11T16:37:06+00:00

The hardware supports transfers up to a page boundary per buffer. Currently, we work around that in the DMA code by splitting each buffer up as we run through the scatterlist. Avoid this by telling the block layers about the hardware restriction. Eventually, this will allow us to phase out the splitting code, but not until the old IDE layer allows us to control the value it gives to blk_queue_segment_boundary(). Signed-off-by: Russell King

[ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King
