Add XXX comments to mark places which need to be taken care of
if we want to remove this part of the kernel from Giant.
Add a comment on a potential performance problem with ip_forward()
file descriptors in programs linked with libc_r with flags
other than the default ones. This kept, inter alia, freopen()
from working correctly when reopening standard streams.

- sshd fails to set TERM correctly.
- privilege separation may break PAM and is currently turned off.
- man pages have not yet been updated
I will have these issues resolved, and privilege separation turned on by
default, in time for DP2.

easier loading of modules that might refer to these interfaces. None
of the code that implements them is standard, just the glue. This
bloats the kernel a whopping 8k.

o ToPIC is happy with two cards now, even when the two cards are
modems.
o Fix (all?) hangs on boot when power is applied to the card. I
suspect that this will make the Ricoh bridges happier and also
make a lot of VAIO owners happy (confirm to me in private email
please :-).
o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards,
to the extent that the underlying hardware supports such cards.
(X.X and Y.Y haven't been assigned values yet :-).
o Better 3.3V support for Ricoh ISA bridges.
How:
o Don't mess with the power register when scanning the cards. It
is unnecessary and causes BADVcc conditions on many chipsets. These
in turn can cause an interrupt storm.
o Make pcic_disable reset the slot's voltage.
o Move initializing voltage for the slot until after it has been
disabled.
o Fix a lot of issues with the pcic_cardbus_power routine. We
now properly enable the card and take it out of reset after
a power change.
o When detecting the card's voltage, if we're in a BadVcc state,
direct the bridge to rescan the card for what it supports.
(we might need to in the future set the power register to 0
before doing this).
o Don't preserve CLKSTOP. need to revisit this.
o Better support for Ricoh ISA bridges for 3.3V cards.
o Don't write to PCIC_POWER directly as offten, but instead go
through the pcic_power interface.
o All cardbus bridges now default to use cardbus power control.
o Add misc register definitions.
o remove some (now) bogus comments.

checksumming. These bugs could possibly cause bad code to be
generated at elevated optimization levels.
First, eliminate the use of preprocessor magic to form the address
fields of asm instructions. It hid the actual addresses being
referenced from the compiler. Without knowledge of all the data
dependencies, the compiler might possibly use optimizations which
would result in incorrect code.
Use "__asm __volatile" rather than "__asm" for instruction sequences
that pass information through the condition codes (the carry bit, in
this case). Without __volatile, the compiler might add unrelated
code between consecutive __asm instructions, modifying the condition
codes. I have seen GCC insert stack pointer adjustments in this
way, for example. Unfortunately, GCC doesn't provide a way to
specify dependencies on the condition codes. You can specify that
they are clobbered, but not that you are going to use them as input.
Finally, simplify the LOAD macro. This macro is used as a poor
man's prefetch. The simpler version gives the compiler more leeway
about just how it performs the prefetch.
