Kernel 2.6.9-rc3-mm3 has a bug in function sys32_io_setup in file
arch/x86_64/ia32/sys_ia32.c.  Local variable ctx64 is not initiated before
sys32_io_setup calls sys_io_setup.  If ctx64 is not zero, and sys_io_setup
will return -EINVAL.  Generic function compat_sys_io_setup has not the bug.

Here is the patch against 2.6.9-rc3-mm3. Just use compat_sys_io_setup to
replace sys32_io_setup.

Here's a patch which backs out the fix Randy Vinson came up with, and makes
i8259_init() and openpic_hookup_cascade() use setup_irq (tested on LoPEC). 
This also converts the rest of the request_irq callers that were expecting the
old behavior (psurge SMP, chrp xmon, 85xx, some 82xx).  This is more untested,
but looks correct.  I've left 8xx alone in this as it needs other changes
before it would make sense.

We've recently noticed that the autonegotiation cleanup made a while
back (between tg3 3.8 and 3.9) has issues which make the link bounce up
and down.

I've traced it to be caused by the tg3_timer 1 second work noticing that
MAC_STATUS_LNKSTATE_CHANGED was set, which driver would see as the link
going down.

Upon further inspection, it appears that we don't wait long enough
between setting SG_DIG_CTRL and reading the SG_DIG_STATUS for the result.

The following patch (from a quasi recent bk tree) makes this code path
wait up to 200ms for the link to establish.  In my testing, I'm seeing
it take around 20ms for the negotiation to complete.

I haven't had the chance to test how this patch affects the case where
the switch doesn't have autoneg enabled, although I suspect fallback
should work correctly.

Please consider applying, thanks,
