[PATCH 0/1] qla2xxx: fix for 2.6.33-rcX

[giridhar.malavali]

From: Giridhar Malavali <giridhar.malavali@qlogic.com>

James,

Can you please apply this patch. This is a critical fix which can cause
panic issues (found on PPC). This needs to be back ported to stable kernel.

  qla2xxx: Obtain proper host structure during response-queue
    processing.

[PATCH 1/1] qla2xxx: Obtain proper host structure during response-queue processing.

[giridhar.malavali]

From: Andrew Vasquez <andrew.vasquez@qlogic.com>

Original code incorrectly assumed only status-type-0
IOCBs would be queued to the response-queue, and thus all
entries would safely reference a VHA from the IOCB
'handle.'

This patch is now in Linus's tree, yet it does not apply to the
2.6.32-stable kernel.  Can you please send a version that does to the
stable@kernel.org address so that I can apply it?

thanks,
