per-process value, and therefpore turns the VM_PSSTRINGS sysctl into a
per-process one as well. This gets rid of a pointer to the bottom of the
stack at a fixed location. Also clears the road for unmapping the stackgap.

This should catch all the same bad cases, but be a little less aggravating
in circumstances where a prototype isn't necessary

- protect pv lists with splvm.
- try to return as soon as possible from pmap_rmproc().
- correctly maintain wired pages statistics.
- invoke pmap_remove_pcb() at splsched to avoid racing the scheduler.

PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h.
PROT_MASK is introduced as the one true way of extracting those bits.
Remove UVM_ADV_* wrapper, using the standard names.

This makes it easier to remove components not required to do an install,
and subsequently add other desireable components ...
In snapshots (in various forks) for about a week.
Do some upgrades and installs, please.

CIRCLEQ_* is deprecated and not called in the tree. The other queue types
have *_END macros which were added for symmetry with CIRCLEQ_END. They are
defined as NULL. There's no reason to keep the other *_END macro calls.

While the index variables were correct the arrays of
dma handles they indexed were swapped for rx and tx.
As there are a mismatched number of rx and tx descriptors
we'd walk off the end of the rx handle array by 30 items.

- Always use either: ((x & RB_XXX) != 0) or ((x & RB_XXX) == 0) in boolean
context (mostly if (x), or x ? y : z)
- prom_halt() in alpha is confirmed to take int as boolean

* you can #include <sys/endian.h> instead of <machine/endian.h>,
and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first)
* those will always export the symbols that POSIX specified for
<endian.h>, including the new {be,le}{16,32,64}toh() set. c.f.
http://austingroupbugs.net/view.php?id=162
if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h>
currently exports (ntohs, NTOHS, dlg's bemtoh*, etc)
* when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and
<arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER
and betoh*

built-ins which aren't available on vax. (A similar diff for m88k is in the

The new CPU_BUSY_CYCLE() may be put in a busy loop body so that CPU can reduce
power consumption, as Linux's cpu_relax() and FreeBSD's cpu_spinwait(). To
start minimally, use PAUSE on i386/amd64 and empty on others. The name is
chosen following the existing cpu_idle_*() functions. Naming and API may be
polished later.

rebooting a machine, like it is done in the hibernate case.
At least some USB host controller drivers rely on this to busy way instead
of sleeping. Avoid a panic on macppc with an uhci(4) cardbus plugged in.

Again remove slightly different comments to reduce diffs. These will be
re-added once boot() become MI and its specification is clearly re-defined.

RB_TIMEBAD is documented well enough that the comment is not needed. sparc64
does slightly different and its comment is left with XXX.

checks, causing the rx ring pointer to stall as soon as an irrelevant
frame is received when the intergace is in bpf+promiscuous or `all multicast'
mode.
Problem spotted and tracked down to the use of bpf by sebastia@. Hair pulling
by me.

with softraid(4) disks.
softraid(4) is the last real consumer of the doshutdownhooks(9) API and it is
not trivial to convert its hook to a DVACT_POWERDOWN handler since the latter
does not allow to sleep.
