| * [SCSI] bfa: kdump fixJing Huang2011-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Root cause: When kernel crashes, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown. So registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to hang during kdump kernel boot. Fix description: during the initialization of first PCI function, reset corresponding register when unclean shutown is detect by reading chip registers.

| * [SCSI] ipr: fix possible false positive detection of stuck interruptWayne Boyer2011-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the driver is getting flooded with interrupts, there's a possibility that the interrupt service routine could falsely detect a stuck interrupt condition and reset the adapter. This patch changes the logic such that the routine will loop back into the command processing code one more time after detecting the stuck interrupt signature. If there are no commands to process after that pass, and the interrupt is still not cleared, then the driver will print the "Error clearing HRRQ" message and reset the adapter.

| * [SCSI] libfcoe: Remove unnecessary module state checksRobert Love2011-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libfcoe's interface consists of create, destroy, enable, disable and create_vn2vn. These are currently module paramaters added durring the module initialization. A concern arose that the module parameters were being added with write permissions before the module had completed initialization. The following code was added to each sysfs store file. * Make sure the module has been initialized, and is not about to be * removed. Module parameter sysfs files are writable before the * module_init function is called and after module_exit. */ if (THIS_MODULE->state != MODULE_STATE_LIVE) goto out_nodev; This check was called out as unhelpful as the module can go dead at any time and therefore its state isn't a reliable thing to look at as a sign of stability and initialization completion. Also, that functional interfaces like these should be added after module initialization. This patch removes the unnecessary checks and hopes to disprove the concern about initialization ordering. Recent fcoe transport rework changes now require fcoe transports to register with libfcoe before any operation can take place. libfcoe may access some static variables but nothing that could cause a problem. Once a fcoe transport is registered, libfcoe is usable and any interface calls will be functional.

This would cause REC response handler to release its fsp pkt hold twice instead once and possibly similar issues with other ELS exchanges in this race. To avoid this race have resp updated under exch lock in rx path, the resp would get set to NULL in case of FC_EX_TIMEOUT under the same lock to prevent resp callback after FC_EX_TIMEOUT.

* | | | | x86: remove 32-bit versions of readq()/writeq()Roland Dreier2011-05-25

To fix this, revert 2c5643b1c5c7 ("x86: provide readq()/writeq() on 32-bit too") and follow-on cleanups. This unfortunately leads to pushing non-atomic definitions of readq() and write() to various x86-only drivers that in the meantime started using the definitions in the x86 version of <asm/io.h>. However as discussed exhaustively, this is actually the right thing to do, because the right way to split a 64-bit transaction is hardware dependent and therefore belongs in the hardware driver (eg mpt2sas needs a spinlock to make sure no other accesses occur in between the two halves of the access). Build tested on 32- and 64-bit x86 allmodconfig.
