  To: James Bottomley; +Cc: linux-scsi, Mark Salyzyn

A patch from Adaptec with byte order changes:
 - drop byte swapping on all 0's and all 1's content
 - fix up missing swapping directives
 - ensure swapping on 16 bit values does not use 32 bit swap
 - reconcile the readl/writel auto-swapping in only most of the
configurations.

I tested this on a ppc64 machine and the driver loaded and configured
the attached disks.

The new cardtype was a documentation. Could have been handled separately
I agree.

*I* have to support the broken port for reasons of expediency. Dropping
this behavior from the kernel.org patch is perfectly fine by me. I was
not sure how extensive this problem was.

that last bit is bogus.  readl/writel are defined to swap bytes on
big endian systems.  Whatever broken Mvista/Windriver or whatever port
doesn't do that should be fixed.

Also please remove unrelated changes like the new cardtypes from the
patch,
follow normal kernel codingstyle (e.g. ||, && at the end of the line)
and
switch to __le* types for harware structures and make sure it's passing
sparse -Wbitwise.
