file so that we have a chance of using gcore on non-i386 platforms. Use
linker sets to reduce the registration glue. Remove md-sparc.c, we do not
have an a.out sparc32 port. aoutcore.c was repocopied from gcore.c.
When it is called directly, gcc is smart enough to generate inline
code for it, which is why it wasn't noticed before that it was missing.
fabs() would probably better fit into libm, but it has traditionally been
in libc on FreeBSD, so there is probably software around that makes
assumptions about this by now.
If somebody wanted to, this could for the beginning of a "libkernel"
which could be used to run kernel code in userland.

Introduce biowait() function. Currently there is a race condition and the
mitigation is a timeout/retry. It is not obvious what kind of locking (if any)
is suitable for BIO_DONE, since the majority of users take are of this
themselves, and only a few places actually rely on the wakeup.

them visible from userland, if need be.
I wish that the C language contained this as part of struct definintions,
but failing that, I would settle for an agreed upon set of functions for
packing/unpacking integers in various sizes from byte-streams which may
have unfriendly alignment.
This really belongs in <sys/endian.h> I guess.
Modified release notes: newsyslog(8) now uses bzip2(1) by default.
Move two TCP-related release notes from the general kernel section to
the networking protocols section. Minor wording adjustment in one
item, note MFC of the other.
code will know not to try to use `long long'.
Unfortunately the GCC spec parser will not allow us to properly detect the
"iso9899:1990" and "iso9899:199409" forms of the acceptable -std= arguments,
because of the ':' in the -std argument. :-( I have left them in the spec
as a place holder in hopes someone knows a way to make the detection of
them work.

(what we want to mask is the ATA interrupts, which run at level splbio),
and add interrupt masking around the statement that modifies the
request queue for a SIM.
This resolves problems reported by users under heavy ATAPI load.

to be dropped, 2) attempting to lock acct_mtx while already holding it.
Sorry to those who experienced pain.
- Added two comments referring to two areas in which acct_mtx is held over
vnode operations that might sleep. Patch in the works for this.
I should have committed this ages ago.
The MFC for if_ethersubr.c could be done in the usual few days (only
ipfw2 uses it), the one for bridge.c should probably wait until
after 4.7 because it changes an existing though mostly undocumented
behaviour (on which i hope nobody relies). All in all, i'll wait for
both things unless there is demand.
MFC after: 35 days
