* pcmcia: fix cisinfo_t removalMarc Zyngier2008-07-151-1/+1
| | | | | | | | | | | | The cisinfo_t removal patch (c5081d5f4775b2a3f858f91151bbf9163e473075 pcmcia: simplify pccard_validate_cis ) introduced a bug that prevented card detection, for the (info->Chains == MAX_TUPLES) check was replaced by (count), which is always true. Restoring the comparison to MAX_TUPLES makes everybody happy...

SCSI cdrom uses blk_rq_map_kern, which properly avoids DMA on the stack by using the bounce buffers. IDE cdrom also has the mechnism to avoids DMA on the stack. So we don't need this extra complexitiy in cdrom.c, such as allocating just 8 bytes. The lower layers can handle it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid allocations causing swap activity on the resume path by preventing the allocations from doing IO and allowing them to access the emergency pools. These paths are used when a frontend device is trying to connect to its backend driver over Xenbus. These reconnections are triggered on demand by IO, so by definition there is already IO underway, and further IO would naturally deadlock. On resume, this path is triggered when the running system tries to continue using its devices. If it cannot then the resume will fail; to try to avoid this we let it dip into the emergency pools.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, ipr does not support HDIO_GET_IDENTITY to SATA devices. An oops occurs if userspace attempts to send the command. Since hald issues the command, ensure we fail the ioctl in ipr. This is a temporary solution to the oops. Once the ipr libata EH conversion is upstream, ipr will fully support HDIO_GET_IDENTITY.

| * | | [SCSI] mptspi: fix oops in mptspi_dv_renegotiate_work()James Bottomley2008-07-081-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem here is that if the ioc faults too early in the bring up sequence (as it usually does for an irq routing problem), ioc_reset gets called before the scsi host is even allocated. This causes an oops when it later schedules a renegotiation. Fix this by checking ioc->sh before trying to renegotiate.

| * | | [SCSI] erase invalid data returned by deviceAlan Stern2008-07-061-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1108) fixes a problem that can occur with certain USB mass-storage devices: They return invalid data together with a residue indicating that the data should be ignored. Rather than leave the invalid data in a transfer buffer, where it can get misinterpreted, the patch clears the invalid portion of the buffer. This solves a problem (wrong write-protect setting detected) reported by Maciej Rutecki and Peter Teoh.
