ba9be04c72 Fixed the commit botch that was causing crashes soon after system 
startup.  Due to the error, the initialization of the zone for
pv_entries was missing.  The system should be usable again.

b79933ebfa Fix some bugs, document vm_zone better. Add copyright to vm_zone.h. Use 
the new zone code in pmap.c so that we can get rid of the ugly ad-hoc
allocations in pmap.c.

3075778b63 Get rid of the ad-hoc memory allocator for vm_map_entries, in lieu of 
a simple, clean zone type allocator.  This new allocator will also be
used for machine dependent pmap PV entries.

570dbb53e0 Eliminate frequent silo overflows by restoring the TEST_LOPRIO code. 
This code was eliminated when the PEND_INTS algorithm was added.  But it was
discovered that PEND_INTS only worsen latency for FAST_INTR() routines,
which can't be marked pending.

23be6be853 Fix a problem with the vfs vnode caching that it doesn't grow quickly 
enough and can cause some strange performance problems.  Specifically, at
or near startup time is when the problem is worst.  To reproduce
the problem, run "lat_syscall stat" from the alpha lmbench code right
after bootup.  A positive side effect of this mod is that the name
cache can be set to grow again by sysctl.  A noticable positive
performance impact is realized due to a larger namecache being available
as needed (or tuned.)

3758b280f2 We got a couple of "map mismatch" panics from the following 
code.  According to the crash dump, bpref is set to 445
and cgp->cg_nclusterblks is 444.  Hence in the for loop,
the test fails immediately but the following failure check
(got == cgp->cg_nclusterblks) doesn't trigger because got >
cgp->cg_nclusterblks.  This wreaks havoc in the code after that.

Fix: Move one source bit to the left  :-)

a78e8d2a83 Fixed security hole with sharing the file descriptor table (via rfork) 
when execing a setuid/setgid binary. Code submitted by Sean Eric Fagan

8ee6f26a8c Make the WD code work on my P6DNF running on the SMP code. It appears 
that there was an "early" interrupt, and this checks for it.

5fd549b62e Fix a problem with ext2fs so that filesystems mounted at reboot don't 
keep ahold of buffers, and therefore leave filesystems dirty.  I haven't
been able to test, but the code compiles.  Those who run -current, please
test and report back!!!  (Sorry :-)).
