Mention about -E and -c options in the BUGS section.
Attempt to make sure that DELAY()/delay() is available in all MD names.
delay() can't use rumpuser_clock_sleep(), because that may unschedule().

Instead, busyloop with calls to rumpuser_clock_gettime().  Fixing delay()
properly should addressed in hypercall rev.18 by introducing a nowrap
variant/flag for rumpuser_clock_sleep().
Use size for the size argument of memcmp, not the result of a compare.
allow sharing Makefiles with rump kernel components
Add hdaudio driver as a rump kernel component

tested by booting a rump kernel on a T61, coupled with a client which
writes some Roy Buchanan to /dev/audio
On second thought, let's not build the rump kernel component for ac97
by default.  The component is not used on a NetBSD target anyway.
Indent.
Add a machdep.unaligned_sigbus sysctl (just like alpha does), but on
arm it is readonly (depends on architecture version).
Use machdep.unaligned_sigbus to skip the unaligned access test on arm
as well.
Skip the SIGFPE test on arm when the FPU does not provide exception handling.

Change debug to diagnostic so that more people see the lossage with bad
random streams, so we can debug it.
Fix uninitialized mutex usage

We use extended attribute mount mutex before testing if it had been
initialized, and as reported by Christos,  this caused panic with
LOCKDEBUG. Fix it by testing before using.
