It gets called by dmu_buf_init_user, which is inline but not static. So it

If the user configures a states_hashsize or source_nodes_hashsize value we may
not have enough memory to allocate this. This used to lock up pf, because these
allocations used M_WAITOK.
Cope with this by attempting the allocation with M_NOWAIT and falling back to
the default sizes (with M_WAITOK) if these fail.

cli_execute is likely the only exception that we should make, due to it
being a global. We don't really need other globals, so this won't really end
up an epidemic.
There's no reason for autoboot handling to be mixed in with menu processing.
It is a distinct process that should only be done once when entering the
menu system.
menu.process has been modified to take an initial keypress to process and to
only draw the screen initially if it's been invalidated. The keypress is
kind of a kludge, although it could be argued to be a potentially useful
kludge if there are other processes that may need to feed a keypress into
the menu system.
In general, every menu redraw is going to require a screen clear and cursor
reset. Each redraw also has the potential to invalidate the alias table, so
we move the alias table being used out into a module variable. This allows
third party consumers to also inspect or update the alias table if they need
to.
While here, stop searching the alias table once we've found a match.
This is driven by an urge to separate out the bits that really only need to
happen when the menu system starts up. Key points:
- menu.process now does the bulk of menu handling. It retains autoboot
handling for dubious reasons, and it no longer accepts a 'nil' menu to
process as 'the default'. Its return value is insignificant.
- The MENU_SUBMENU handler now returns nothing. If menu.process has exited,
then we continue processing menu items on the parent menu as expected.
- menu.run is now the entry point of the menu system. It checks whether the
menu should be skipped, processes the default menu, then returns.
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]
