sure that i686_mem was only used when
1. CPUID had MTRR set (this was there before)
2. the CPU was GenuineIntel (not there)
3. the CPU is a 686 (also not there)
This should prevent any problems with CPUs that set MTRR but aren't
compatibile with Intel's interface (none that I know of yet.)
uni-directional parallel port should use olpt driver instead of lpt
driver.
Files ppc.c and ppcreg.h are copied form i386/isa directory with PC98
change.

automatically hacks on the active copy of the IDT if f00f_hack()
has changed it. This also allows simplifications in setidt().
This fixes breakage of FP exception handling by rev.1.55 of
sys/kernel.h. FP exceptions were sent to npx.c's probe handlers
because npx.c "restored" the old handlers to the wrong copy of the
IDT. The SYSINIT for f00f_hack() was purposely run quite late to
avoid problems like this, but it is bogusly associated with the
SYSINIT for proc0 so it was moved with the latter.

"nowin95" as arguments to the "-o" flag, as alternatives to "-G", "-s",
"-l", and "-9"; when running "mount_msdos" by hand, that doesn't let you
do anything you couldn't already do, but if you're letting "mount" run
it, it lets you specify those options, which is especially useful if,
for example, you have an entry in "/etc/fstab" for some file system,
with "noauto" set, so you can conveniently mount a DOS partition from a
removable drive and force it to treat the file system as VFAT rather
than boring old FAT.

This is the change to struct sockets that gets rid of so_uid and replaces
it with a much more useful struct pcred *so_cred. This is here to be able
to do socket-level credential checks (i.e. IPFW uid/gid support, to be added
to HEAD soon). Along with this comes an update to pidentd which greatly
simplifies the code necessary to get a uid from a socket. Soon to come:
a sysctl() interface to finding individual sockets' credentials.
1) Handle forking and non-forking internal services correctly.
Turn on wrapping for internal services because it works now.
2) Preserve server names for each service on HUP.
3) Honour hosts_options(5) severity option.
4) Add IMPLEMENTATION NOTES section to clarify TCP Wrappers
usage and limitations.
This change may cause previously allowed builtin services (e.g. daytime)
to be denied in existing configurations.

creating a new entry. vm_map_stack and vm_map_growstack can panic when
a new entry isn't created. Fixed vm_map_stack and vm_map_growstack.
Also, when extending the stack, always set the protection to VM_PROT_ALL.
like the original PNIC and the MX98715A (from which the PNIC II is derived).
This requires special handling. Save the card type, and in mx_calchash(),
if we see that the card is a PNIC, return only the low 7 bits of the
hash instead of the low 9 bits.
would occur when clustering them - caused by running out of buffers
and taking a degenerate code path as a result. It appears that waiting
instead for buffers to become available is okay.
