to avoid lock order problems when manipulating the sockets associated
with the fifo.
Minor optimization of a couple of calls to fifo_cleanup() from
fifo_open().
. forward declare all static functions
. add a couple of redundant parens in return statements where they've
been missing
. remove the space after exit since it's a function
reimplementations of enodev() (for the smbread() and smbwrite()
functions), as well as fixing various errno values to conform to
errno(3).
Bruce also points out that a number of the pointer == NULL tests
are probably nonsense because the respective checks are already
done at upper layers.

remove the empty line between the fdc and sio devices. The empty
line suggests that the comment applies to fdc only while it applies
to all following devices and options.

Correct my previous commit and add a comment to the manpage
indicating that the user must set errno to 0 if they wish to
distinguish "no such user" from "error".

used for IA32 based systems.

This is much faster -- about twice as fast in some crude benchmarks.

same value as the local variable did...
repocopied. Soon there will be additional bus attachments and
specialization for isa, acpi and pccard (and maybe pc98's cbus).
This was approved by nate, joerg and myself. bde dissented on the new
location, but appeared to be OK after some discussion.
constants the wrong way on the VAX. Instead, use C99 hexadecimal
floating-point constants, which are guaranteed to be exact on binary
IEEE machines. (The correct hexadecimal values were already provided
in the source, but not used.) Also, convert the constants to
lowercase to work around a gcc bug that wasn't fixed until gcc 3.4.0.

different context support for 32 vs 64 bit processes. This simply omits
the save/restore of the segment selector registers for non 32 bit
processes. This avoids the rdmsr/rwmsr juggling when restoring %gs
clobbers the kernel msr that holds the gsbase.
However, I suspect it might be better to conditionally do this at
user<->kernel transition where we wouldn't need to do the juggling in the
first place. Or have per-thread extended context save/restore hooks.
hal_raise_irql(void) doesn't take an argument, but it is called with one.
eg: irql = FASTCALL1(hal_raise_irql, DISPATCH_LEVEL);
This is hidden by the macros on i386, but becomes a compile error on amd64
since the arguments are actually checked.

off to see what the 64 bit Intel cpus did, but it doesn't seem to help
much there either. Oh well, store it in the Attic.

been removed. Please coordinate future quirk issues with sanpei@
