When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares
the current time against the time estimated for the current hardware
pointer to detect xruns.  The somewhat fuzzy threshold in the while loop
makes it possible that hdelta becomes negative; the comparison being
done with unsigned types then makes the loop go through the entire 263
negative range, and, depending on the value, never reach an unsigned
value that is small enough to stop the loop.  Doing this with interrupts
disabled results in the machine locking up.

To prevent this, ensure that the loop condition uses signed types for
both operands so that the comparison is correctly done.

Many thanks to Kelly Anderson for debugging this.

When aborting a PCM stream, the xrun is signaled only if the stream is
running.  When disconnecting a PCM stream, calling snd_card_disconnect()
too early would change the stream into a non-running state and thus
prevent the xrun from being noticed by user space.

To prevent this, move the snd_card_disconnect() call after the xrun.

When m_start returns an error, the seq_file logic will still call m_stop
with that error entry, so we'd better make sure that we check it before
using it as a vma.

Introduced by commit ec6fd8a4 ("report errors in /proc/*/*map*
sanely"), which replaced NULL with various ERR_PTR() cases.

(On ia64, you happen to get a unaligned fault instead of a page fault,
since the address used is generally some random error code like -EPERM)

irq_desc checking in a function which is called with that irq
descriptor locked, is pointless. Equally pointless as the irq desc
check in the interrupt service routine. The driver sets those lines
up, so that cant go away magically.

Remove the open coded handler magic and use the proper accessor.

No need to fiddle with irq_desc in the type setting function. The
original value is in irq_data and the core code stores the new setting
when the return value is 0.

There is no point in checking irq_desc here, as it _is_ available. The
driver configured those lines, so they cannot go away.

The home brewn disabled/note_interrupt magic can be removed as well by
adding a irq_disable callback which avoids the lazy disable.

That driver needs to be converted to threaded interrupts.
