1abc77f86d if kmem_malloc() fails while trying to allocate an mbuf cluster, try 
and free some space by calling m_reclaim().  Also, log the "mb_map full"
error message (at most) every 60-seconds.  The old code would log it
once over the lifetime of the system, but that's not a useful diagnostic.
(More useful is the new behaviour, which roughly indicates how often
periods of heavy load occur, without spamming the console and system
logs with messages.)

06c209646e handle the case where kmem_malloc() returns NULL in the 'can wait' case. 
Right now, this code just panic()s (same as kmem_malloc() used to do
before, but different message), but in the future it should be modified
to try to reclaim wasted memory.

1e2b610d5a #ifdef __alpha__, call a machine-dependent function with new device 
structure and 'aux', right before ca_attach is called for the
newly-attached device.  This allows the alpha port to do root device
autodetection without modifying every bus and device driver which could
be in the 'boot path.'  In the long run, it may make sense to make
this machine-independent.

e7ef034c05 Add NTP kernel precision timekeeping from Dave Mill's xntp distribution 
and the "kernel.tar.Z" distribution on louie.udel.edu, which is older than
xntp 3.4y or 3.5a, but contains newer kernel source fragments.

This commit adds support for a new kernel configuration option, NTP.
If NTP is selected, then the system clock should be run at "HZ", which
must be defined at compile time to be one value from:
  60, 64, 100, 128, 256, 512, 1024.

Powers of 2 are ideal; 60 and 100 are supported but are marginally less
accurate.

If NTP is not configured, there should be no change in behavior relative
to pre-NTP kernels.

These changes have been tested extensively with xntpd 3.4y on a decstation;
almost identical kernel mods work on an i386.  No pulse-per-second (PPS)
line discipline support is included, due to unavailability of hardware
to test it.

With this in-kernel PLL support for NetBSD, both xntp 3.4y and xntp
3.5a user-level code need minor changes. xntp's prototype for
syscall() is  correct for FreeBSD, but not for NetBSD.

c0cdc0cf04 when printing data modified on the free list: 
(1) do not cast it to (void *), and
	(2) print it as 0x%x, rather than %p.
This is not perfect (because the data being printed is "int32_t"-sized), but
is more correct than printing it as a pointer because the data is _not_ a
pointer, it is data to be printed in hex, and on some systems, pointers are
wider than the data items being printed, which leads to excess and misleading
output.  The only 'right' solution to this is to have a printf specifier
that prints the fixed-sized types the right way, and that's not really
practical.

5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

a2ce90f34c change definition of profil() to make it 64-bit friendly. This has 
no practical consequence on 32-bit systems.  old prototype was
int profil(char *, int, int, int), and new one is int profile(char *,
size_t, u_long, u_int).  the size_t is the size of the buffer,
and the u_long is the 'starting offset'.  (I changed the last int
to u_int, because it's treated as a u_int everywhere, and isn't
logically a signed value.)

da93322976 define lkm_nofunc, to be used instead of nosys (blech!) for unused load, 
unload, and stat functions.  arguably could (should?) use NULL instead,
but this is a bit more descriptive.  also, unconditionally call the
load/unload/stat functions, as now they're known to work (because, at
worst, they're lkm_nofunc).
