[openib-general] OFED 1.2 updated to 2.6.20-rc1, UCMA in

[Michael S. Tsirkin]

OK, I pulled v2.6.20-rc1 from linus (actually, the immediately following
d1998ef38 which fixes a compilation issue in ib_verbs.h) into ofed 1.2 tree.
I'll continue to pull with each RC but I expect no more major API changes.

Main things that had to be backported:
- ilog API f0d1b0b30d250a07627ad8b9fbbb5c7cc08422e8
- kmemdup API (actually introduced in 2.6.19: bed8bdfddd851657cf9e5fd16bb44abb02ae7f42)
- work_struct related changes c4028958b6ecad064b1a6303a6a5906d4fe48d73

All backports have been updated to work with that kernel version,
so if you have based you development on that, please fetch and
rebase as appropriate.

This brings in the UCMA module (sans the the multicast patches),
so it should be now possible to run userspace that relies
on UCMA on OFED 1.2 kernel code.

Wrt multicast:
Sean, could you please prepare multicast tree based on 2.6.20-rc1
(+hopefully recent fixes) so I can test that with OFED?

Wrt iser:
please note that due to recent decision to include the iscsi module
in OFED 1.2, iser can't built on older kernels until someone
(presumably from voltaire) clones ofed_1.2 and looks into backporting
iscsi too.

I'll be off Wed/Thursday, so please Cc Vlad on any questions/issues.

Thanks,
