These indices were assigned the same values as they would've been implicitly
assigned anyways.
While here, throw terminating commas after the last value of tables.
With r329882, in the absence of a free page shortage we would only take
len(PQ_INACTIVE)+len(PQ_LAUNDRY) into account when deciding whether to
aggressively scan PQ_ACTIVE. Previously we would also include the
number of free pages in this computation, ensuring that we wouldn't scan
PQ_ACTIVE with plenty of free memory available. The change in behaviour
was most noticeable immediately after booting, when PQ_INACTIVE and
PQ_LAUNDRY are nearly empty.

It should use the common parser, but it should not be processed like a
standard file. Rewite check_nextboot to read the file in, check whether it
should continue, then parse as needed.
This allows us to throw the recently introduced check_and_halt callback
swiftly out the window.
config.parse is now purely a parser, rather than a whole proccessor. The
standard process for loading a config file has been split out into
config.processFile.
This clears the way for having nextboot read its own config file and decide
there whether it should parse the rest of the file.
This is step 1 towards revoking config.parse of it I/O privileges. Ideally,
all reading would be done before config.parse and config.parse would just
take text and parse it rather than being charged with the entire process.

There are no parts useful for usermode applications in
vm/vm_pageout.h. Even for the specific applications like fstat and
lsof.
In my opinion, this protection is redundant and instead userspace
should not include the header at all. Since there are apparently
broken third party codebases, give them a bit of slack by providing
transitional period.

Functionally, the latter error wouldn't necessarily hurt anything. io.write
will just error out as it's not passed a valid file handle. Still, we can do
better than that.
The functionality was correct, but our style guidelines tend to request that
we shy away from using boolean operations in place of explicit comparisons
to nil.
config.parse now takes an extra callback that is invoked on the full text of
the config file. This callback dictates where we should actually try to
parse this file or not.
For nextboot, we use this to halt parsing if we see 'nextboot_enable="NO"'.
If we don't, parse it and write 'nextboot_enable="NO" ' to it. The same
caveat as with forth still applies- writing is only supported by UFS.
Write support (even if it only works on UFS) will be needed for nextboot
functionality.

These interfaces were put in place to let QorIQ SoCs dictate CPU idling
semantics, in order to support capabilities such as NAP mode and deep sleep.
However, this never stabilized, and the idling support reverted back to
CPU-level rather than SoC level. Move this code back to cpu.c instead. If
at a later date the lower power modes do come to fruition, it should be done
by overriding the cpu_idle_hook instead of this platform hook.
When I wrote the patch, I wanted to remove SYSINIT() usage from amd64 code.
There is no reason to keep the divergence any more because iwasaki merged
most amd64 suspend/resume code to i386 with r235622. Note this also fixed
an enge case reported by royger. [1]

use it to regulate page daemon output.
This provides much smoother and more responsive page daemon output, anticipating
demand and avoiding pageout stalls by increasing the number of pages to match
the workload. This is a reimplementation of work done by myself and mlaier at
Isilon.

No implementation of fpu_kern_enter() can fail, and it was causing needless
error checking boilerplate and confusion. Change the return code to void to
match reality.
(This trivial change took nine days to land because of the commit hook on
sys/dev/random. Please consider removing the hook or otherwise lowering the
bar -- secteam never seems to have free time to review patches.)
