qla1280 compile problems

[Christoph Hellwig]

[and now with jes's _full_ email address for an actually working
 delivery.  did I mention I hate email today?]

The qla1280 update still has some issues, mostly because it backs
out all the 2.5 changes applied to the driver in the last months,
also it doesn't work on ia64 because the IA64 generic build references
sn2-specific symbols that don't exist in that build.

Jes, can you look at the 2.5 changes that went in after your last merge
and make the SN2 vchan workaround a config option?

For reference, this is the compile errors on ppc:

Christoph,

Which version of the driver are you testing and what kernel? I tried
it out fairly recently on 2.5.x (2.5.59 or so) and it compiled without
any problems.

I will take a look at building it against the latest 2.6.0-test
kernel. However, I am not going to make the vchan workaround a new
config option, it doesn't make any sense as it's already protected by
CONFIG_IA64_SGI_SN2 || CONFIG_IA64_GENERIC. The appropriate patches
for that have already been pushed for 2.4 and Jesse is about to push
them out for 2.5.

Cheers,
Jes

That's Jame's latest scsi-misc-2.5 tree, i.e. Linus' tree from four days
ago plus lots of scsi-related chanhges including qla 3.23.34.

It does make sense.  Your punishing all ia64 users for SN2 breakage
although 95% (or probably more) of the IA64 boxens won't ever need it.

And no, so far SN2 isn't part of the generic IA64 build in either 2.4
or 2.5 although it's hopefully going to happen soon for 2.5.

Ok, will take a look at this.

Punishing? thats why you have the option to compile the kernel as
CONFIG_IA64_HP_ZX1 or CONFIG_IA64_DIG. The point of the generic kernel
is that it will boot on all boxes, thats why this feature is only
enabled for generic kernels or sn2 specific. Second, the 'cost' of
this is a test and a branch and even on sn2 it just flips a
bit. Hardly comparable to the cost of loading the address into the
device.

I'll check what the status is, if it prevents current kernels from
building I'll of course take it out for now.

Could you be more explicit on this?  I thought I'd re-added all of the
backed out patches (although I might have missed some).

For what it's worth, this compiled for me without warnings on parisc64
(although I haven't got around to actually testing it).

These seem to be missing at least

 - remove all #include <linux/blk.h>'s (Adrian Bunk)
 - give ->proc_info a struct Scsi_Host * paramter (me)
 - move all host templates into .c files (me)
 - Spellig fixes for consistent, dependent and persistent
 - Spellig fixes
 - [patch, 2.5] scsi_qla1280.c free on error path

strange, I can's see how it could compile at least with the superflous
initializer for sht.command.
