and MPU IRQs to reflect more common/default settings.

at device attach time, instead of allocating and freeing buffers as
necessary. But he or she forgot to remove the line that invalidated
the buffer when the device is closed. Therefore, after using the
device for the first time, the buffer was incorrectly invalidated and
that caused a page fault on the second, and subsequent uses.

also implies VM_PROT_EXEC. We support it that way for now,
since the break system call by default gives VM_PROT_ALL. Now
we have a better chance of coalesing map entries when mixing
mmap/break type operations. This was contributing to excessive
numbers of map entries on the modula-3 runtime system. The
problem is still not "solved", but the situation makes more
sense.
Eventually, when we work on architectures where VM_PROT_READ
is orthogonal to VM_PROT_EXEC, we will have to visit this
issue carefully (esp. regarding security issues.)

2.2-BETA users should disable it using npx0 flags 0x04 the same as
2.2-ALPHA users should have.

workings of #error in particular. He also broke the 2.2 build with this
change, leading me to wonder whether or not the changes were ever even
tested. Folks, I'm happy to see people work directly on 2.2 like
this and will continue to encourage Nate to make direct commits, but
please TEST before committing! I think that's a more than reasonable
prerequisite, and this code could never have worked at all, leading me to
believe that Nate skipped this most basic of steps.
Don't allow people to use the 'dedicated' drivers at the same time as
the generic support code, as it can cause all sorts of problems
including kernel crashes.

Broke locking on named pipes in the same way as locking on non-vnodes
(wrong errno). This will be fixed later.
The fix involves negative logic. Named pipes are now distinguished from
other types of files with vnodes, and there is additional code to handle
vnodes and named pipes in the same way only where that makes sense (not
for lseek, locking or TIOCSCTTY).
This makes unexpected faults (in an interrupt handler) more likely
to crash properly. It could be done even better (more robustly and
more efficiently) using lazy fault handling.
They were garbage that happened to be 0 in many cases. (real_to_prot()
happens to leave the value of the real-mode %cr0 in %eax and the
memory-size BIOS calls usually don't touch the upper bits of %eax.
The upper 16 bits of %cr0 are usually 0 at boot time, at least on
486's.
Should be in 2.2.
configure() where it always belonged. It was originally slightly
misplaced after configure(). Rev.138 left it completely misplaced
before the DEVFS, DRIVERS and CONFIGURE sysinits by not moving it
together with configure().
Restored the printing of bootinfo.bi_n_bios_used now that it can

EISA slots to probe. This is mainly intended to allow installing the
system on an HP Netserver with an on-board AIC7xxx EISA SCSI
controller, that is sitting on EISA slot # 11.
Documentation updates explaining this hack will follow shortly.
Note that this can go away again as soon as the EISA device probing
is more intelligent about the address space clash with the PCI address
space.

again; they are still questionable).

Makefile.i386:
Align functions to 16-byte boundaries if profiling is enabled. This
will allow a fourfold reduction in the size of the profiling buffers.
I've added an installation from optical disk drive facility.
This enables FreeBSD to be installed from an optical disk, which
may be formatted in "super floppy" style or sliced into MSDOS-FS
and UFS partitions.
Note: ncr.c should be reviewed by Stefan Esser <se@freebsd.org>
and cd.c by Joerg Wunsch <joerg@freebsd.org> before bringing this
into 2.2.
