contrary to what the comments say, the code does not account for the
overhead of a page structure per page of physical memory. This revision
changes the code to match the comments.

The case for which this was added, r274807, causes this warning to
always show. LOCAL_DIRS=foo LOCAL_LIB_DIRS=foo/lib. The only case in
which r274807 is a problem is if foo/Makefile does not contain
SUBDIR+=lib, which is a normal convention. LOCAL_LIB_DIRS is a special
hack only to get a library into the _generic_libs list for the
'make libraries' bootstrapping phase. The old behavior changed in
r274807 was only in head during the 10.0 cycle, so the warning was
only ever needed until release anyhow.

As of r313097, the HotPlug code requires the link to support

Also, warn about LOCAL_CREDS effective uid/gid fields, since the write could
be from a setuid or setgid program (with the explicit SCM_CREDS and
LOCAL_PEERCRED, the credentials are read at such a time that it can be
assumed that the process intends for them to be used in this context).

This means that FPU is always initialized and handled when available,
and SSE+ register file and exception are handled when available. This
makes the kernel FPU code much easier to maintain by the cost of
slight bloat for CPUs older than 25 years.
CPU_DISABLE_CMPXCHG outlived its usefulness, see the removed comment
explaining the original purpose.

MAXPHYS bytes of data, the I/O would require MAXPHYS + PAGE_SIZE worth
of pages to do the I/O and we'd hit an assertion in
vm_fault_quick_hold_pages unless MAXPHYS was larger than 1M +
PAGE_SIZE.
There is one capability explicitly documented in gettytab(5) as stupid: he.
And it is indeed. It was meant to facilitate system hostname modification,
but is hardly usable in practice because it allows very limited editing
(e.g., it depends on a particular hostname length, making it non-generic).
Replace it with simple implementation that treats ``he'' as POSIX extended
regular expression which is matched against the hostname. If there are no
parenthesized subexpressions in the pattern, entire matched string is used
as the final hostname. Otherwise, use the first matched subexpression.
If the pattern does not match, the original hostname is not modified.
Using regex(3) gives more freedom, does not complicate the code very much,
and makes a lot more sense, in turn making ``he'' less stupid and actually
useful (e.g., it is now possible to obtain node or domain names from the
original hostname string, without knowing it in advance).

Some PCI-e bridges report that they support HotPlug in the slot
capabilities but do not report support for Data Layer Active events
in the link capabilities register. These bridges do not work correctly
when HotPlug is used. Further, while the description of HotPlug in
the spec does not mention that DL active events are required, the
description of the link capabilities register says that DL active is
required for HotPlug. Thanks to Dave Baukus for finding that language
in the spec.

* flesh out a "get default DFS parameters" routine

This allows the radar pulse reporting code to function, but it doesn't yet

- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
By this, any SMP kernel can be compiled with SMP_ON_UP support.
- Enable runtime detection of CPU multiprocessor extensions only
if SMP_ON_UP option is used. In other cases (pure SMP or UP),
statically compile only required variant.
- Don't leak multiprocessor instructions to UP kernel.
- Correctly handle data cache write back to point of unification.
DCCMVAU is supported on all armv7 cpus.
- For SMP_ON_UP kernels, detect proper TTB flags on runtime.
