8fa8ae3d0d 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.

10b9d7be19 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.

4811e46aa5 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.)

14e530a9e3 remove unused MAXVNODEUSE macro. 1997-08-04 07:31:36 +00:00

b3f221cd7a 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  :-)

b8ed1d9a7f 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.

ec0474c458 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 :-)).

6422ff5313 fix a few problems with pty. warn about how if you only have 1 pty 
defined, your really getting 32.  Also warn about how you can't have
more than 256 pty's when your using DEVFS (non DEVFS can use more, just
the makedev script doesn't know how to make >256).  it also doesn't
allocate more memory than needed in this case.

Make sure that the signal passed in TIOCSIG isn't 0 as it might cause
a panic.  I personally haven't seen this happen, but after a similar
bug in syscons crashed my machine, I'm acutely aware of this one. :)
