03282658c5 recent changes have caused TRAP_TRACING to induce corruption 
disable until the issue has been tracked down

da35e3e55f Turn console printf buffering into a kernel option and only on 
by default for sun4v where it is absolutely required.

This change moves the buffer from struct pcpu to the stack to avoid
using the critical section which created a LOR in a couple of cases
due to interaction with the tty code and kqueue. The LOR can't be
fixed with the critical section and the pcpu buffer can't be used
without the critical section.

Putting the buffer on the stack was my initial solution, but it was
pointed out that the stress on the stack might cause problems
depending on the call path. We don't have a way of creating tests
for those possible cases, so it's best to leave this as an option
for the time being. In time we may get enough data to enable this
option more generally.

46355dc4e0 - add separate variable for enabling printing of ranges 
- simplify handling of rounding phys_avail ranges to 4M boundaries (needed for all
  memory to be in the direct mapped area)

1eddb5f0f6 - Explicitly name the fields in pcb that we use to store trap state for later 
retrieval, rather than using pad
- save the fault address in sfar for use by the alignment fixup handler
- mask off the trap number, so the context id doesn't confuse the UT_MAX
  comparison

This change fixes alignment fixup handling which is needed for traceroute
to work in spite of its copious unaligned accesses

4e25808d33 We no longer need to remap hardware trap numbers to sparc64 trap numbers 
as this happens much earlier in trap handling.

The fact that we continued to do this when it was no longer necessary caused
breapoint to map to SIGILL as opposed to SIGTRAP :-(.

f3bb6f6787 Make sure we do not sleep while locks are held. Change the malloc(9) 
flags from M_WAITOK to M_NOWAIT. This should not cause any problems
since the calling code appears to properly handle failed allocations.

86dd766979 In contrast to the non-obvious and flexible nature of the optimized bcopy in t1_copy.S (which 
shall retain its CDDL copyright, and thus likely be removed from GENERIC) I have removed the CDDL
from hcall.S because there is zero flexibility in the implementation of hypercalls as they derive
directly from the hypervisor interface which is not copyrighted (ironically the source for the
hypervisor itself is BSD licensed).

It is best to start any bikeshed about this as soon as possible.
