device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):
- bwap16() and bswap32(). These have optimized implementations on some
architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
versa, using a naming scheme like le16toh(), htole16().
These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
conversion (while the normal access functions would if the bus endianess
differs from the CPU endianess).
htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.
Make use of the new functions in a few places where local implementations
of the same functionality existed.

2) Don't compile vendor ID.
3) WARNS=4 fixes (constness, make a global local to avoid shadowing, unused
parameters, rename local to avoid shadowing, remove junk after #endif)
4) remove some "register"s.
2) Cast some numbers we know to be positive to size_t before we MIN them
with the result of a sizeof.
3) Compare result of inet_addr to INADDR_NONE, not -1.
There is some unresolved badness that has been eluding me, particularly
affecting uniprocessor kernels. Turning off PG_G helped (which is a bad
sign) but didn't solve it entirely. Userland programs still crashed.
1/ conditionalise (#if 0) function that is not used.
Unused code left in place for netBSD compatibility.
2/ Recode loop to convince gcc that it does initialise a variable
(use do-while instead of for() so gcc knows that we always go through
at least once. Feel free to check my logic.
Both ends of the pipe share a pool_mutex, this makes allocation
and deadlock avoidance easy.
Remove some un-needed FILE_LOCK ops while I'm here.
There are some issues wrt to select and the f{s,g}etown code that
we'll have to deal with, I think we may also need to move the calls
to vfs_timestamp outside of the sections covered by PIPE_LOCK.
work loads. It tapers off after that as gcc's working set generally just fits.

code into cardbus and s/pci/cardbus. This exposes a few pci_*
functions that are now static.
This work is similar to work Justin posted to the mobile list about a
year or two ago, which I have neglected since then.
This is a subset of his current work with the multiple inheritance
newbus architecutre. When completed, that will eliminate the need for
pci/pci_private.h.
Similar work is needed for the cardbus_cis and pccard_cis code as well.
spares (the size of the field was changed from u_short to u_int to
reflect what it really ends up being). Accordingly, change users of
xucred to set and check this field as appropriate. In the kernel,
this is being done inside the new cru2x() routine which takes a
`struct ucred' and fills out a `struct xucred' according to the
former. This also has the pleasant sideaffect of removing some
duplicate code.

shootdowns in a couple of key places. Do the same for i386. This also
hides some physical addresses from higher levels and has it use the
generic vm_page_t's instead. This will help for PAE down the road.
