aic7xxx_pci.c:
When performing our register test, be careful
to avoid resetting the chip when pausing the
controller. The test reads the HCNTRL register
and then writes it back with the PAUSE bit
explicitly set. If the last write to the controller
before our probe is to reset it, the CHIPRST
bit will still be set, so we must mask it off
before the PAUSE operation. On some chip versions,
we cannot access registers for a few 100us after
a reset, so this inadvertant reset was causing PCI
errors to occur on the read to check for paused
status.

Reimplement pmap_release() such that it uses the page table rather than
the pte object to locate the page table directory pages. (Temporarily,
retain an assertion on the emptiness of the pte object.)
systems where the data/stack/etc limits are too big for a 32 bit process.
Move the 5 or so identical instances of ELF_RTLD_ADDR() into imgact_elf.c.
Supply an ia32_fixlimits function. Export the clip/default values to
sysctl under the compat.ia32 heirarchy.
Have mmap(0, ...) respect the current p->p_limits[RLIMIT_DATA].rlim_max
value rather than the sysctl tweakable variable. This allows mmap to
place mappings at sensible locations when limits have been reduced.
Have the imgact_elf.c ld-elf.so.1 placement algorithm use the same
method as mmap(0, ...) now does.
Note that we cannot remove all references to the sysctl tweakable
maxdsiz etc variables because /etc/login.conf specifies a datasize
of 'unlimited'. And that causes exec etc to fail since it can no
longer find space to mmap things.
Instead, use EXCA_MEMREG_WIN_SHIFT which is the amount we shift the
bus address by to write into upper memory (eg above 24MB). Use the
latter in this case.

Skinny is the protocol used by Cisco IP phones to talk to Cisco Call
Managers. With this code, one can use a Cisco IP phone behind a FreeBSD
NAT gateway.
Currently, having the Call Manager behind the NAT gateway is not supported.
More information on enabling Skinny support in libalias, natd, and ppp
can be found in those applications' manpages.

32 bit binary stuff. 32 bit binaries do not like it much when the kernel
tries hard to put things above the 8GB mark.
I have a work-in-progress to fix this properly, but I didn't want to burn
anybody with this yet.
initialize a TSC timecounter until we know if it is broke or not.
XXX I think there is a bug in the i386 code here. init_TSC_tc() comes
after:
if (statclock_disable)
return;
ie: if you turn off the statclock interrupt, you dont get the TSC either.
