3c58d5b25f My clever hack was not enough. Disable DELAY via ifndef _RUMPKERN in 
subr_prf until I manage to get all archs in line with a proper MI
signature.

167269d42c Include kernel printf routines in rump instead of relying on the 
magic libc symbol.  This also allows to bid farewell to subr_prf2.c
and merge the contents back to subr_prf.c.  The host kernel bridging
is now done via rumpuser_putchar().

44a89fbb01 Squelch type-punning warnings with void * casts. We are allowed 
to do this because the pointers do not have aliases.

0e983d35cf * unexpose kprintf locking internals 
* migrate from simplelock to kmutex

Don't bother to bump kernel version, since nothing outside of subr_prf
used KPRINTF_MUTEX_ENXIT()

339f5c5772 Add ISO partition detection enabling auto-detection of iso9660 and UDF 
partitions on optical media like CD/DVD/BD but also on all other media if
there is no NetBSD disklabel or MBR label.

Also fix cd's readdisklabel arguments so the ioctl's arrive at the right
device (!) and update its default label to make more sense.

7ca206492d Don't try to sync if panicing: 
- It doesn't work and a dead system that can't be reset from the console is
  worse than a system that has painced and rebooted. If you can make it work
  reliably please do so.

- If the system is paniced there is every reason to suspect VM structures
  and the contents of the buffer cache.

6d599f4e1f - Fix a bug where we trashed descriptor zero in the old open files array 
while ironically trying to preserve the same during copy. Would only have
  occurred if a multithreaded program expanded the descriptor table and,
  within a tiny window of exposure, another thread in the program tried to
  access descriptor zero.

- Convert to use kmem_alloc/kmem_free.

82ae73e0b6 Don't increment the 'kpreempt defer: IPL' counter if a preemption is pending 
and we try to process it from interrupt context. We can't process it, and
will be handled at EOI anyway. Can happen when kernel_lock is released.

81649575af When checking for "set-up is complete", look for the CTLFLAGS_PERMANENT 
in the root of the tree being modified, rather than in the system default
tree.  This permits module compat_netbsd32 to initialize its shadow tree
at load time.

Discussed on tech-kern, with no objections.

9c68331911 Store config(1)'s root filesystem type as a text string rather than 
embedding the address of its xxx_mountroot() in swapnetbsd.c.  This
permits booting of kernels with hard-wired filesystem type even if the
filesystem is in a loadable module (ie, not linked into the kernel
image).

Discussed on current-users.  Tested on amd64 and i386 with both hard-
wired and '?' filesystem times, and on both modular and monolithic
kernels.

Thanks to pooka@ for code review and suggestions.
