9b009b5d4a Make fxp(4) INTR_MPSAFE (but do not enable MPSAFE just yet):
- 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.
  Remove MTX_RECURSE flag from sc_mtx. [gallatin]
- 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]
- You don't need to bzero softc.

93ce6848ad - Relax the Giant required in vm_page_remove().
- Remove the Giant required from vm_page_free_toq().  (Any locking
   errors will be caught by vm_page_remove().)

This remedies a panic that occurred when kmem_malloc(NOWAIT) performed
without Giant failed to allocate the necessary pages.

081b5fb1f6 Import latest changes from the vendor. This also is reported to fix the
driver at long last!
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.

3d51b3a280 Add an argument to get_mcontext() which specified whether the
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.

88151c4f8c Fix a bug with df on large (>1TB) nfsv3 file servers on 32 bit client
machines where the 'long' number of blocks in struct statfs wont fit.
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.

4e35cc9041 It seems that 1 was not a magic value as I thought, but a coincidence.
Instead of applying the adjustment to processes with a start time of 1,
apply it to all processes with a start time of less than 3600.

None of this would be necessary if the start times were recorded in ticks
instead of seconds and microseconds.

89c52cff2e - Reorganize osigstack() to do the copyin first, grab the proc lock once,
