[SCSI] qla2xxx: Add support for ISP82xx to capture dump (minidump) on failure.
Minidump allows us to catpure a snapshot of the firmware/hardware states at the time of failure for further analysis. [jejb: added missing #include <linux/vmalloc.h> Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> ] Signed-off-by: Giridhar Malavali <giridhar.malavali@qlogic.com> Signed-off-by: Chad Dupuis <chad.dupuis@qlogic.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
