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.
1.131 is slightly broken, and I would commit the fix to that here, but it
has been reported that any deviation from the original code is causing
problems with some 82557 chips, causing them to lock hard.
Until those issues have been figured out, going back to the original
code is the best plan.
Frustrated: Silby
so that the data is less likely to be inconsistent if SYSCTL_OUT() blocks.
If the data is large, wire the output buffer instead.
This is somewhat less than optimal, since the handler could skip the copy
if it knew that the data was static.
If the data is dynamic, we are still not guaranteed to get a consistent
copy since another processor could change the data while the copy is in
progress because the data is not locked. This problem could be solved if
the generic handlers had the ability to grab the proper lock before the
copy and release it afterwards.
This may duplicate work done in other sysctl handlers in the kernel which
also copy the data, possibly while a lock is held, before calling they call
a generic handler to output the data. These handlers should probably call
SYSCTL_OUT() directly.
SYSCTL_OUT() from blocking while locks are held. This should
only be done when it would be inconvenient to make a temporary copy of
the data and defer calling SYSCTL_OUT() until after the locks are
released.
1) Define _KERNEL while including sys/time.h to get some function prototypes.
2) Add prototypes and ANSIify definitions.
3) Constness changes.
4) Remove register keyword.
5) Actually return a sensible value from main.
6) Make fread_tail take a void * instead of a char *.
7) Avoid a signedness warning by casting to a size_t. Should be safe
enough 'cos we also check for nonnegativity.
8) Be extra chummy with sigset_t rather than passing a struct to printf
and pretending it is an int.
userland for libc/gmon to compile, so the typedef in <machine/types.h>
isn't good enough. This is really ugly since we end up with the
actual value which uintfptr_t is typedef'd from, in multiple places.
This is bug for bug compatible with the other FreeBSD architectures.
