1- fix sysfs has more than one value per file
2- PAE issues (cast of dma_addr_t to unsigned long)
3- unblock SYNCHRONIZE_CACHE

Areca had tested its arcmsr linux raid driver on ppc machines G5 and it worked fine.

Not the world perhaps, but I'm unwilling to concede that if a driver
author is given a list of major issues and does nothing, then the driver
should go in after everyone gets impatient.

The rules for inclusion are elastic and include broad leeway for good
behaviour, but this would stretch the elasticity way beyond breaking
point.

The list of issues is here:

http://marc.theaimsgroup.com/?l=linux-scsi&m=114556263632510

I'm under the impression that Erich is under the impression that they've all
been addressed.

Most of the serious stuff is fixed with the exception of:

- sysfs has more than one value per file
- BE platform support
- PAE (cast of dma_addr_t to unsigned long) issues.
- SYNCHRONIZE_CACHE is ignored. This is wrong. The sync cache in the
shutdown notifier isn't sufficient.

So this is progress.

Erich, can you please fix these things up and then re-review the issues
list which I'm maintaining in
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17/2.6.17-mm2/broken-out/areca-raid-linux-scsi-driver.patch,
make sure that everything has been addressed?

If there are some things in those lists which you cannot/will not address
then please identify them and give us the reasoning behind your decision.
