Clean up the code by converting xpmap_ptom(VTOP(...)) to VTOM(...) and
converting xpmap_ptom(VM_PAGE_TO_PHYS(...)) to VM_PAGE_TO_MACH(...). In
a few places we take advantage of the fact that xpmap_ptom can commute with
setting PG_* flags.
This commit should have no net effect save to improve the readability of
this code.

the SIFTR pfil(9) hook functions to or from all network stacks. This patch
allows packets inbound or outbound from a vnet to be "seen" by SIFTR.
Additional work is required to allow SIFTR to actually generate log messages for
all vnet related packets because the siftr_findinpcb() function does not yet
search for inpcbs across all vnets. This issue will be fixed separately.

This way, when there is a dependency between two modules, the handler of the
latter probed runs first.
This is a similar approach as the modules are unloaded in the same
linkerfile.

pages. The pinning of NPGPTD pages is #if 0ed out in pmap_pinit (I'm
not quite sure why...) and this commit adds a corresponding #if 0 in
pmap_release to avoid unpinning those pages.
Some versions of Xen seem to silently ignore requests to unpin pages
which were never pinned in the first place, but some return an error
(causing FreeBSD to panic) prior to this commit.
These MSRs can be used to determine actual (average) performance as
compared to a maximum defined performance.
Availability of these MSRs is indicated by bit0 in CPUID.6.ECX on both
Intel and AMD processors.

It seems that this MSR has been available in a range of AMD processors
families for quite a while now.
Note1: not all AMD MSRs that are found in amd64 specialreg.h are also in
the i386 version.
Note2: perhaps some additional name component is needed to distinguish
AMD-specific MSRs.

This was removed in 2001 but I think it is appropriate to add it back:
* I do not want to encourage people to write fragile and non-portable echo
commands by making printf much slower than echo.
* Recent versions of Autoconf use it a lot.
* Almost no software still wants to support systems that do not have
printf(1) at all.
* In many other shells printf is already a builtin.
Side effect: printf is now always the builtin version (which behaves
identically to /usr/bin/printf) and cannot be overridden via PATH (except
via the undocumented %builtin mechanism).
Code size increases about 5K on i386. Embedded folks might want to replace
/usr/bin/printf with a hard link to /usr/bin/alias.
path id for enumerating the available busses. Previously camcontrol was
implicitly passing 0 as the first path id, which meant that if bus 0 was not
present camcontrol would fail with EINVAL instead of rescanning/resetting any
busses that were present.

backing storage. Such pages might be then reused, racing with the
assert in vm_object_page_collect_flush() that verified that dirty
pages from the run (most likely, pages with VM_PAGER_AGAIN status) are
write-protected still. In fact, the page indexes for the pages that
were removed from the object page list should be ignored by
vm_object_page_clean().
Return the length of successfully written run from vm_pageout_flush(),
that is, the count of pages between requested page and first page
after requested with status VM_PAGER_AGAIN. Supply the requested page
index in the array to vm_pageout_flush(). Use the returned run length
to forward the index of next page to clean in vm_object_page_clean().

on the page addition. Page removals do not affect the dirtiness of the
