2010-09-05[SCSI] scsi/block: increase flush/sync timeoutMike Christie2-2/+3
We have been seeing the flush request timeout with a wide range of hardware from tgt+iser to FC targets from a major vendor. After discussions about if the value should be configurable and what the best value should be, this patch just increases the flush/sync cache timeout to 1 minute. 2 minutes was determined to be too long, and making it configurable was troublesome for users. This patch was made over Linus's tree. It is not made over scsi-misc or scsi-rc-fixes, because Linus's had block layer changes that my patch was built over.

In the case when an ep_connect request is interrupted due to route request stall, if the iSCSI daemon is terminated by the user, the chip will be left in a state which will not get cleaned up upon module removal. Upon module reload, when the same context id is used for a new connection, chip panic would occur. This patch adds chip cleanup in the module removal path.

2010-08-29firewire: ohci: work around VIA and NEC PHY packet reception bugStefan Richter1-1/+9
VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write packet event codes for received PHY packets (or perhaps write evt_no_status, hard to tell). Work around it by overwriting the packet's ACK by ack_complete, so that upper layers that listen to PHY packet reception get to see these packets. (Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643, JMicron JMB381 --- these do not exhibit this bug.) Clemens proposed a quirks flag for that, IOW whitelist known misbehaving controllers for this workaround. Though to me it seems harmless enough to enable for all controllers. The log_ar_at_event() debug log will continue to show the original status from the DMA unit.

This doesn't make much sense since this error has been lost anyway so no need for reporting it separately. Thus, report the overflow bit setting in the MCE dump instead. While at it, remove reporting of MiscV and ErrorEnable (en) which are superfluous.
