Dave Olson 60e845035a IB/ipath: Don't count IB symbol and link errors unless link is UP
Implement the ignoring of ibsymbol errors and linkrecover errors while
the link is at less than INIT (long needed), to get accurate counts.
Particularly an issue when doing non-IBTA DDR negotiation with chips
from vendors that do not support IBTA mode negotiation.  If the driver
is unloaded, and there is a delta, the adjusted counters are written
back to the chip, so they stay adjusted across driver reload.

The check for max physical address was incorrect, thus limiting the
range of allowed physical addresses.

Niels de Vos 61a2d07d3f Remove newline from the description of module parameters
Some module parameters with only one line have the '\n' at the end of the
description.  This is not needed nor wanted as after the description the
type (i.e.  int) is followed by a newline.

Some modules contain a multi-line description, these are not affected
by this patch.

Dave Olson e2ab41cae4 IB/ipath: Need to always request and handle PIO avail interrupts
Now that we always use PIO for vl15 on 7220, we could get stuck forever
if we happened to run out of PIO buffers from the verbs code, because
the setup code wouldn't run; the interrupt was also ignored if SDMA was
supported.  We also have to reduce the pio update threshold if we have
fewer kernel buffers than the existing threshold.

Clean up the initialization a bit to get ordering safer and more
sensible, and use the existing ipath_chg_kernavail call to do init,
rather than doing it separately.

Drop unnecessary clearing of pio buffer on pio parity error.

Drop incorrect updating of pioavailshadow when exitting freeze mode
(software state may not match chip state if buffer has been allocated
and not yet written).

If we couldn't get a kernel buffer for a while, make sure we are
in sync with hardware, mainly to handle the exitting freeze case.

Michael Albaugh 5f51efc195 IB/ipath: Only warn about prototype chip during init
We warn about prototype chips, but the function that checks for
support is also called as a result of a get_portinfo request, which
can clutter the logs.

Restrict warning to only appear during initialization.

Roland Dreier 44957572cc IB/ipath: Remove tests of PCI_MSI in ipath_iba7220.c
The PCI MSI interface is stubbed out properly so that all the
functions just return failure if PCI_MSI=n, so there's no reason to
have "#ifdef CONFIG_PCI_MSI" blocks in ipath_iba7220.c.
