f550a707bd Added a new version of trap_pfault() that disallows kernel page faults 
to the user address space unless pcb_onfault is set. The code is currently
commented out because iBCS2 and process debugging parts of the kernel
need to be changed/fixed first.

9eefa8bfc4 Add a dummy ___bb_init_func for BB profiling of the kernel. 
To use this: recompile src/gnu/usr.bin/cc, compile your kernel.  The
files you want to profile should be compiled with '-a -g'.  "strip -x"
the kernel and run.  You don't need to profile all files in the kernel.
My next commit is the program to extract the data from the running kernel.

bf3e3428b6 Changed the printf()s in npxattach a bit so you don't end up with 
messages like this:

wdc0 at 0x1f0-0x1f7 irq 14 on isa
wdc0: unit 0 (wd0): <ST506>
wd0: size unknown, using BIOS values: 615 cyl, 4 head, 17 sec, bytes/sec 512
npx0 at 0xf0-0xff irq 13 on motherboard
npx0: changing root device to wd0a
^^^^^^

The spurious 'npx0: ' pops up if you have a 386 with a 387 FPU.

fde2cdc48a Various changes from John and myself that do the following: 
New functions create - vm_object_pip_wakeup and pagedaemon_wakeup that
are used to reduce the actual number of wakeups.
New function vm_page_protect which is used in conjuction with some new
page flags to reduce the number of calls to pmap_page_protect.
Minor changes to reduce unnecessary spl nesting.
Rewrote vm_page_alloc() to improve readability.
Various other mostly cosmetic changes.

188291d20f Do away with 'options SWAP_GENERIC' once and for all: I get ill 
just thinking about it.

Two changes need to be made to allow 'config kernel swap generic' to
work properly without requiring any compile-time flags:

/usr/src/usr.sbin/config/mkswapconf.c: we need to define a dummy stub
for the setconf() function to replace the one in swapgeneric.c that
isn't available in non-generic configurations.

/usr/src/sys/i386/i386/autoconf.c: the -a boot flag causes setroot()
to be skipped and lets setconf() prompt the user for a root device.
If you skip setroot() in a non-generic kernel, you could get severely
hosed. To avoid this, we silently ignore the -a flag if rootdev != NODEV.
(rootdev is always initialized to NODEV in swapgeneric.c, so if
we find that rootdev is something other than NODEV, we know we're
not using a generic configuration.)

648c711bb4 This is the latest version of the APM stuff from HOSOKAWA, I have looked 
briefly over it, and see some serious architectural issues in this stuff.

On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.

Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.
