Problem report (against 2.4.x driver) from Jeff Layton
<jlayton@redhat.com>:
An OEM noticed that the U6 qla2200 driver would hang for
around 2 minutes at boot time and then proceed normally. I
found that the delay was occurring when loading the new
firmware into the card, and was due to a
schedule_timeout(10) added to the bottom of the polling
loop.
Some testing showed that the load ram operation on the card
was very quick (on the order of a couple of jiffies), but
the sleep in the polling loop was making each operation take
around 25-30.
The attached patch corrects this by making it skip sleeping
during the load ram operation, since I believe we only do
that when the module is plugged in. It also skips sleeping
if the mbox_int flag got set during the current loop.
This corrected the hang on my test setup, and OEM also
confirmed that it corrected the problem for them.

Mailbox commands are polled for completion during ISP
initialization. During potentially 'long' mailbox commands
(i.e. fabric login), we really don't want a busy-wait delay
to potentially trigger a (benign) soft-lockup BUG().

Add requisite structure definitions and #define's for ISP24xx
support. Also drop volatile modifiers from device_reg_* register
layouts as the members are never really accessed, only their
offsets within the layout are used during reads and writes.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
