Andrew hi.
Above 2 patches are no longer needed as they are fixed.
qla1280 - is in git-scsi-rc-fixes.patch and
ppa & imm - are in git-scsi-misc.patch
on the other hand arm-scsi is broken and its patch
is in scsi-pending. I have attached a scsi-pending-arm-convert-to-accessors.patch
for your convenience.
Thanks Boaz
