While races there are not fatal, they cause result underestimation, that
cause unneeded ARC reclaims.

ba29f2ddfb MIPS rtld: report missing symbol rather than segfaulting
This is only an interim fix; MIPS should be using the MI code instead,
which does not have this issue.

f6e6460dfc Add support for the MIPS74K SoC family performance counters events.
These are similar to the mips24k performance counters - some are
available on perfcnt0/3, some are available on perfcnt1/4.
However, the events aren't all the same.

* Add the events, named the same as from Linux oprofile.
* Verify they're the same as  "MIPS32(R) 74KTM Processor Core Family
  Software User's Manual"; Document Number: MD00519; Revision 01.05.
* Rename INSTRUCTIONS to something else, so it doesn't clash with
  the alias INSTRUCTIONS.  I'll try to tidy this up later; there
  are a few other aliases to add and shuffle around.

Tested:

* QCA9558 SoC (AP135 board) - MIPS74Kc core (no FPU.)
* make universe; where it didn't fail for other reasons.

TODO:

* It'd be nice to support the four performance counters
  in at least this hardware, rather than just two.

28cbb9b173 Unify Book-E and AIM trap.c
Summary:
Book-E and AIM trap.c are almost identical, except for a few bits.  This is step
1 in unifying them.

This also renumbers EXC_DEBUG, to not conflict with AIM vector numbers.  Since
this is the only one thus far that is used in the switch statement in trap(),
it's the only one renumbered.  If others get added to the switch, which conflict
with AIM numbers, they should also be renumbered.

d30c6f8edf fts: Don't return FTS_SLNONE if it's not a symlink (if race).
When following symlinks, fts returned FTS_SLNONE when fstatat(flag=0)
failed, but a subsequent fstatat(flag=AT_SYMLINK_NOFOLLOW) succeeded. This
incorrectly triggered if a filename existed to be read from the directory,
was deleted before the fstatat(flag=0) and created again after the
fstatat(flag=0).

Fix this by only returning FTS_SLNONE if the result from
fstatat(flag=AT_SYMLINK_NOFOLLOW) is actually a symlink. If it is not a
symlink, treat it as if fstatat(flag=0) succeeded.

a8b0f1009d Replace vm_fault()'s heuristic for automatic cache behind with a heuristic
that performs the equivalent of an automatic madvise(..., MADV_DONTNEED).
The current heuristic, even with the improvements that I made a few years
ago, is a good example of making the wrong trade-off, or optimizing for
the infrequent case.  The infrequent case being reading a single file that
is much larger than memory using mmap(2).  And, in this case, the page
daemon isn't the bottleneck; it's the I/O.

In all other cases, the current heuristic has too many false positives,
i.e., it caches too many pages that are later reused.  To give one
example, thousands of pages are cached by the current heuristic during a
buildworld and all of them are reactivated before the buildworld
completes.  In particular, clang reads source files using mmap(2) and
there are some relatively large source files in our source tree, e.g.,
sqlite, that are read multiple times.  With the new heuristic, I see fewer
false positives and they have a much lower cost.

I actually tried something like this more than two years ago and it
didn't perform as well as the cache behind heuristic.  However, that was
before the changes to the page daemon in late summer of 2013 and the
existence of pmap_advise().  In particular, with the page daemon doing
its work more frequently and in smaller batches, it now completes its
work while the application accessing the file is blocked on I/O.
Whereas previously, the page daemon appeared to hog the CPU for so long
that it caused "hiccups" in the application's execution.

Finally, I'll add that the elimination of cache pages is a prerequisite
for NUMA support.

3d8e91f9ce urtwn: blink the LED when scanning.
Previously, the driver was trying to blink the LED in the newstate
function, but that only gets called once (unlike OpenBSD's net80211
stack).  Move the LED blinking to set_channel().

While there, don't try to set the channel when we switch to the SCAN
state.  This is already accomplished by the set_channel() function.

11d48637a1 boot1 EFI: reset the screen and select the best mode.
It's necessary to reset the screen to make sure any vendor pixels are
gone when we start boot1.  In the Lenovo X1 (3rd gen), this is the
only way to clear the screen.  Previously, the Lenovo logo would only
disappear after the kernel started scrolling the display.

After resetting the screen, EFI could put us in the worst LCD mode
(oversized characters), so we now find the largest mode we can use and
hope it's the most appropriate one (it's not trivial to tell what's
the correct LCD resolution at this point).  It's worth noting that the
final stage loader has a 'mode' command that can be used to switch
text modes.

While there, enable the software cursor, just like in the legacy boot
mode.

to include the Unaligned Access and Floating-point Half-precision

unaligned data, the latter that the binary uses the VFPv3/Advanced SIMD
half-precision extension.

These may be emmitted by clang so it's best to print a warning when the
linker hits one of them.
