8e641f354a Found by coverity issue 887. Check for NULL before using base_ph so 
an interpreter that does not have PT_LOAD in the program header doesn't
crash the system.

94c70b92a9 Check the "oldlen" argument to sysctl(2) before passing it 
to vslock(9). This prevents a local DOS.
(The checks against system and user limits for wired
memory should be centralized in UVM; for now prefer a less
invasive fix which can be pulled pulled up into releases.)

209be910b7 Support the generation of coredumps for 32-bits binaries under 
COMPAT_NETBSD32.  They haven't worked for 5 years.

Silently agreed by the tech-kern readers.

XXX sparc64 MD glue still lacking.
XXX The FPU registers on i386 are not dumped correctly, according to my
XXX tests.  It shouldn't be much work for someone who has the slightest
XXX idea of how that stuff is supposed to be laid out on i386.

61dd49d3bc Syscall debug tracing is handled by trace_enter() / trace_exit(). Change 
trace_is_enabled() to return TRUE if SYSCALL_DEBUG is defined, and g/c

routines.

be8b235384 Clean up fallout proc_is_traced_p() change: 
- proc_is_traced_p() -> trace_is_enabled(), to match trace_enter() and
  trace_exit().
- trace_is_enabled() becomes a real function.
- Remove unnecessary include files from various files that used to care
  about KTRACE and SYSTRACE, but do no more.

f6f0eee324 Change the way semid_t values are chosen. Instead of using kernel 
addresses, use a uint32_t counter and the machinery to properly use it.
That makes the ksem_* system calls friendly for COMPAT_NETBSD32.

ec5a93183a merge yamt-uio_vmspace branch. 
- use vmspace rather than proc or lwp where appropriate.
  the latter is more natural to specify an address space.
  (and less likely to be abused for random purposes.)
- fix a swdmover race.

70c82cfa56 Medium-sized overhaul of POOL_SUBPAGE support so that: 
1: I can understand it, and
2: It works.
Notable externally-visible changes are that POOL_SUBPAGE now has to be a
compile-time constant, and that trying to initialise a pool whose objects are
larger than POOL_SUBPAGE automatically generates a pool that doesn't use
subpages.

NetBSD/acorn26 now boots multi-user again.
