- The proc lock is enough to cover reading p_state, so push down sched_lock
into the PRS_NORMAL case of the switch on p_state.
- Mark the ktrace() and utrace() syscalls as being MP safe.
- Validate the facs argument to ktrace() prior to doing any vnode
operations or acquiring any locks.
- Share lock the proctree lock over the entire section that calls
ktrsetchildren() and ktrops(). We already did this for process groups.
Doing it for the process case closes a small race where a process might
go away after we look it up. As a result of this, ktrstchildren() now
just asserts that the proctree lock is locked rather than acquiring the
lock itself.
- Add some missing comments to #else and #endif.
FreeBSD flags instead of just adding one to the Linux flags. This should
be identical to the previous version except that I have at least one report
of this patch fixing problems people were having with Linux apps after my
last commit to this file. It is safer to use the switch then to make
assumptions about the flag values anyways, esp. since we currently use
MD defines for the values of the flags and this is MI code.

following changes have been done:
- stylify. The original code was too hard to read.
- get rid of a number of compilation options (Adaptec-only, Eni-only, no-DMA).
- more debugging features.
- locking. This is not correct yet in the absence of interface layer locking,
but is correct enough to not to cause lock order reversals.
- remove RAW mode. There are no users of this in the tree and I doubt that
there are any.
- remove NetBSD compatibility code. There was no way to keep NetBSD non-busdma
and FreeBSD busdma code together.
- if_en now buildable as a module.
This has been actively tested on sparc64 and i386 with ENI server and
client cards and an Adaptec card (thanks to kjc).

I hate search and replace sweeps like this as much as anyone else, but
in each case I used both alternatives within a single document, so I'm
trying to enforce some internal consistency.

fs_sblockloc is a byte offset, not a fragment number. This change makes

- Add fxp_start_body() and change fxp_start() to just acquire locks and
then call fxp_start_body(). Places that would call fxp_start() with
locks held (mutex recursion) now call fxp_start_body() directly.

- Change fxp_attach() to work without the softc lock, saving interrupt
hooking until the head of fxp_attach().
- Call ether_ifattach() before overriding ifp parameters. This reverts
part of 1.155.
- Remove multiple error paths in fxp_attach().
- Teardown interrupt in fxp_detach() before unlocking the softc.
- Make sure mutex is not held in fxp_release()
- Delete the miibus instance and/or self in fxp_release(), not in
fxp_detach(). This can happen if attach fails partway through.
- Move ifmedia_removeall to fxp_release() since attach may fail after
media have been allocated.
- Add locking to fxp_suspend, fxp_resume, fxp_start, fxp_intr,
fxp_poll, fxp_tick, fxp_ioctl, fxp_watchdog.
- Pass in ifp to fxp_intr_body since its callers sometimes already use
it.
- Add compatibility define for INTR_MPSAFE for 4.x. [gallatin]

Many thanks to vaidas.damosevicius@if.lt for keeping this issue alive
and pursuing Intel for a fix, Intel/ICP for working on the driver, and
Sergey Osokin for bringing the original patches up to 5-CURRENT.
Also, put a small work around into devd to prevent a hang on boot this
would cause because select used to return 2 rather than 0 for no
evetnts due to a bug I fixed a few days ago in subr_bus.c. I'll
remove this workaround May 7th. You have until then to upgrade your
kernel if you want to run a new devd with an older kernel.
syscall return values should be cleared. The system calls
getcontext() and swapcontext() want to return 0 on success
but these contexts can be switched to at a later time so
the return values need to be cleared in the saved register
sets. Other callers of get_mcontext() would normally want
the context without clearing the return values.
Remove the i386-specific context saving from the KSE code.
get_mcontext() is not i386-specific any more.
Fix a bad pointer in the alpha get_mcontext() code. The
context was being bcopy()'d from &td->tf_frame, but tf_frame
is itself a pointer, so the thread was being copied instead.

where we want to take the disklabel filesystem type of "4.2BSD" and use
fsck_4.2bsd on those filesystems.
Add a comment about why the code is there, now that we know:
* XXX This is a kludge to make automatic filesystem type guessing
* from the disklabel work for "4.2BSD" filesystems. It does a
* very limited subset of transliteration to a normalised form of
* filesystem name, and we do not seem to enforce a filesystem
* name character set.

Instead of chosing an artificial 512 byte block size, simply scale it up
until we avoid an overflow. NFSv3 reports the sizes in bytes, and the
blocksize is a figment of nfsclient's imagination.
