users to re-enable the old behavior in case it's needed for some systems.
We never disable in the power-off path.

machine.c. The traditional condition was (pctcpu > 0 || SRUN), but the
negation of the condition logic (from select to skip) made this come
out as (pctcpu > 0 && SRUN), leading to a very erratic display, except
for purely CPU bound processes.
This has been discussed in the mail lists some time ago and I have used

the page daemon would only have been awakened the first time that the
number of pv entries went above the high water mark, not each time.
S_IFDIR when making a directory
S_IFLNK when making a symbolic link
S_IFIFO when making a pipe
xfs_ialloc() checks this field for these flags when figuring
out whether to make a directory, make a symbolic link or make a pipe.
firmware_get() will not work while resuming. Note that we can't
simply drop the FIRMWARE_UNLOAD flag, because that will result in
a firmware image that can never be unloaded by the user since the
firmware subsystem will hold a linker reference to it (it's not
clear that firmware_put() without FIRMWARE_UNLOAD ever does quite
what you'd want).
with firmware_unregister(). Previously when the last driver reference
had been dropped we would clear the list entry under the assumption
that the firmware module was about to be unloaded, but this was not
true if the firmware image had been loaded manually with kldload.
This makes it possible to manually kldload firmware images as a
workaround for drivers such as ipw that attempt to load firmware
while resuming after a suspend.

- Move sonewconn(), which creates new sockets for incoming connections on
listen sockets, so that all socket allocate code is together in
uipc_socket.c.
- Move 'maxsockets' and associated sysctls to uipc_socket.c with the
socket allocation code.
- Move kern.ipc sysctl node to uipc_socket.c, add a SYSCTL_DECL() for it
to sysctl.h and remove lots of scattered implementations in various
IPC modules.
- Sort sodealloc() after soalloc() in uipc_socket.c for dependency order
reasons. Statisticize soalloc() and sodealloc() as they are now
required only in uipc_socket.c, and are internal to the socket
implementation.
After this change, socket allocation and deallocation is entirely
centralized in one file, and uipc_socket2.c consists entirely of socket
buffer manipulation and default protocol switch functions.

* Add an assert to detect if the wakecode ever grows too big. We include
1 KB for stack, which should be more than enough also.
* Remove unnecessary initialization of static variables.
* Add comments and a bootverbose print giving the page phys address.

the code anyway to a private page.
* Clear the direction flag and eflags. Probably not necessary but it won't
hurt to be safe.
* Add prefixes to all instructions to prevent any assembler mistakes.
* Remove zeroing of eax - edi. We use those registers immediately after
to transfer values to protected mode so this was pointless.
* Update comments to reflect info found during code review.
