is that some cards built around fm801 chip have the same device ID, only
have radio tuner onboard, but no sound capabilities. Therefore, with such
card inserted and `device pcm' in kernel the user has a big problem, as
the fm801 driver effectively hangs the machine when trying to initialise
nonexistent ac97 codecs (it does 500 retries with 1 second interval!).
It would be better if MediaForte's engeneers were smart enough to put
different device ID into such cards, but it isn't an option.

be swapped out. Do not put such the thread directly back to the run
queue.

While I am here, s/PS_TIMEOUT/TDF_TIMEOUT/.
the PAM_ECHO_PASS option on-the-fly is a NOP (though it wasn't with the
old pam_get_pass(3) code). Instead, call pam_prompt(3) directly. This
actually simplifies the code a bit.

vm_page_sleep_busy() with vm_page_sleep_if_busy(). At the same time,
increase the scope of the page queues lock. (This should significantly
reduce the locking overhead in vm_object_page_remove().)
o Apply some style fixes.
swapped in, we do not have to ask for the scheduler thread to do
that.
- Assert that a process is not swapped out in runq functions and
swapout().
- Introduce thread_safetoswapout() for readability.
- In swapout_procs(), perform a test that may block (check of a
thread working on its vm map) first. This lets us call swapout()
with the sched_lock held, providing a better atomicity.
conventions for _mcount and __cyg_profile_func_enter are different, so
statistical profiling kernels build and link but don't actually work.
IWBNI one could tell gcc to only generate calls to the former.
Define uintfptr_t properly for userland, but not for the kernel (I hope).
except for the fact tha they are presently swapped out. Also add a process
flag to indicate that the process has started the struggle to swap
back in. This will be needed for the case where multiple threads
start the swapin action top a collision. Also add code to stop
a process fropm being swapped out if one of the threads in this
process is actually off running on another CPU.. that might hurt...

<stdint.h>. Previously, parts were defined in <machine/ansi.h> and
<machine/limits.h>. This resulted in two problems:
(1) Defining macros in <machine/ansi.h> gets in the way of that
header only defining types.
(2) Defining C99 limits in <machine/limits.h> adds pollution to
<limits.h>.
problems with the firmware and will result in a) poor performance and
b) the inability to associate certain types of cards (most notibly
cisco).
Idea obtained from OpenBSD, but I implemented it by clearing the
IFF_PROMISC flag rather than the refusing to honor it downstream.
