====================
net: ipa: little fixes

This series adds a few small fixes to the IPA code.

The first patch appeared in a different form in June, and got some
pushback from David because he felt a problem that can be caught at
build time *should* be caught at build time.
  https://lore.kernel.org/netdev/20200610195332.2612233-1-elder@linaro.org/
I agree with that, but in this case the "problem" was never actually
a problem.  There's a little more explanation on the patch, but
basically now we remove the BUILD_BUG_ON() call entirely.

The second deletes a line of code that isn't needed.

The third converts a warning message to be a debug, as requested by
Stephen Boyd.

And the last one just gets rid of an error message that would be
output after a different message had already reported a problem.

net: ipa: change a warning to debug

When we determine from hardware what the size of IPA memory is
we compare it against what we learned about it from DT.

If DT defines a region that's larger than actual memory, we use the
smaller actual size and issue a warning.

If DT defines a smaller region than actual memory we issue a warning
too.  But in this case the difference is harmless; so rather than
issuing a warning, just provide a debug message instead.

net: ipa: don't break build on large transaction size

The following call in ipa_validate_build() is erroneous:

    BUILD_BUG_ON(sizeof(struct gsi_trans) > 128);

The fact is, it is not a bug for the size of a GSI transaction to be
bigger than 128 bytes.  The correct operation of the driver is not
dependent on the size of this structure.  The only consequence of
the transaction being large is that the amount of memory required
is larger.

The problem this was trying to flag is that a *slight* increase in
the size of this structure will have a disproportionate effect on
the amount of memory used.  E.g. if the structure grew to 132 bytes
the memory requirement for the transaction arrays would be about
double.

With various debugging build flags enabled, the size grows to 160
bytes.  But there's no reason to treat that as a build-time bug.

GSO offload. This does not happen after this change, and all types

====================
net: ipa: constrain GSI interrupts

The goal of this series is to more tightly control when GSI
interrupts are enabled.  This is a long-ish series, so I'll
describe it in parts.

The first patch is actually unrelated...  I forgot to include
it in my previous series (which exposed the GSI layer to the
IPA version).  It is a trivial comments-only update patch.

The second patch defers registering the GSI interrupt handler
until *after* all of the resources that handler touches have
been initialized.  In practice, we don't see this interrupt
that early, but this precludes an obvious problem.

The next two patches are simple changes.  The first just
trivially renames a field.  The second switches from using
constant mask values to using an enumerated type of bit
positions to represent each GSI interrupt type.

The rest implement the "real work."  First, all interrupts
are disabled at initialization time.  Next, we keep track of
a bitmask of enabled GSI interrupt types, updating it each
time we enable or disable one of them.  From there we have
a set of patches that one-by-one enable each interrupt type
only during the period it is required.  This includes allowing
a channel to generate IEOB interrupts only when it has been
enabled.  And finally, the last patch simplifies some code
now that all GSI interrupt types are handled uniformly.

not working at all until:
commit 8fdcabeac398 ("drivers/net/wan/x25_asy: Fix to make it work")

1.
The uses of "struct x25_asy" in x25_asy_unesc (when receiving) and in
x25_asy_write_wakeup (when sending) are not protected by locks against
x25_asy_change_mtu's changing of the transmitting/receiving buffers.
Also, all "netif_running" checks in this driver are not protected by
locks against the ndo_stop function.

2.
The driver stops all TTY read/write when the netif is down.
I think this is not right because this may cause the last outgoing frame
before the netif goes down to be incompletely transmitted, and the first
incoming frame after the netif goes up to be incompletely received.

And there may also be other problems.

I was planning to fix these problems but after recent discussions about
