On 32 bits, we may suffer IRQ 13, or supposedly we might have a buggy
implementation which gives spurious trap 16. We did not check for
this on 64 bits, but there is no reason we can't make the code the
same in both cases. Furthermore, this is presumably rare, so do the
spurious check last, instead of first.

In the case of multiple FPU errors, prioritize the error codes,
instead of returning __SI_FAULT, which ends up pushing a 0 as the
error code to userspace, a POSIX violation.
For i386, we will simply return if there are no errors at all; for
x86-64 this is probably a "can't happen" (and the code should be
unified), but for this patch, return __SI_FAULT|SI_KERNEL if this ever
happens.

Set-Interface request only when the interface is not already in

Impact: cleanup, remove dead debug code
I ran across some old debugging code in vmi paravirt-ops code that was
already dead, but still potentially useful. After reviewing recent
changes to the way kernel page tables are allocated and initialized, and
the lack of bugs caught by this debugging code, I've concluded it is now
totally useless to have around, and it's already been #if 0'd for quite
some time.
There's no rush to get this in mainline, but it's also totally harmless,
so I'll let the x86 maintainers decide where it should be tucked. I've
been out of the mainstream dev loop for a couple months, so apologies if
I haven't got any protocol changes in order.

Make the driver report an ENXIO error immediately upon NAK instead of
waiting for another interrupt and getting a timeout.
When reading from a device that is not present or declines to respond
to, e.g., a non-existent register address, CPM immediately reports a
NAK condition in the TxBD, but the driver kept waiting until a timeout,
which takes 1 second and causes an ugly console error message.
