Residency count track the number of pte entries installed into the
current pmap, which does not reflect the consumption of the physical
memory by the address map. Due to several mechanisms like pv entries
reclamation, copy on write etc. the resident pte entries count may be
much less than the amount of physical memory kept by the process.
Provide the OOM-specific vm_pageout_oom_pagecount() function which
estimates the amount of reclamaible memory which could be stolen if
the process is killed.

other actions, swaps out kernel stacks of the processes. On the other
hand, currentl OOM logic which selects a process to kill in the
critical condition, skips process with swapped-out thread. Under some
loads, this results in the big(gest) process being ignored by OOM.
Do not skip a process which has inhibited thread due to the swap-out,
in the OOM selection loop. Note that killing such process requires
the thread stack page-in, but sometimes this is the only way to
recover.

- Fix style(9) bugs
- Fix compiler warnings
- Use `nitems(x)` instead of `sizeof(x) / sizeof(*x)` pattern
The testcases will be converted over to ATF eventually, but for now will be
integrated in as plain C tests

The QCA953x SoC is an integrated 2x2 2GHz 11n + MIPS24k core, with
a 5 port FE switch, gige WAN port, and all the same stuff you'd find on
its predecessor - the AR9331.
However, buried deep in here somewhere is also a PCIe EP/RC for various
applications and some other weird bits I don't yet know about.
This is enough to get the reference board up and booting. I haven't yet
had it pass lots of packets - I need to finalise the ethernet switch
bits and the GMAC configuration (ie, how the ethernet ports and switch
are wired up) and I'll bring that in when I commit the base configuration
files to use the thing.
The wifi stuff will come much later. I have to port that support from
Linux ath9k and extend our vendor HAL to support it.
The reference board (AP143) comes with 32MB RAM and 4MB flash, so in order
to use it I need to get USB working fully so I can run root from there.
Thankyou to Qualcomm Atheros for access to the reference design board.
Details:
* Add register definitions from openwrt;
* It looks like a QCA955x but shrunk down to a QCA933x footprint, so
use the QCA955x bits and fix up the clock detection code to do the
QCA953x bits (they're very subtly different);
* Teach GPIO about it;
* Teach EHCI about it;
* Teach if_arge about it;
* Teach the CPU detection code about it.
Tested:
* AP143, QCA9533v2 SoC

- Split up the testcases into C locale and ja_JP.eucJP testcases.
- Avoid a segfault in the event that setlocale fails, similar to r290843

Provide more meaningful diagnostic messages if LC_CTYPE can't be set properly
instead of segfaulting, because setlocale returns NULL and strcmp(NULL, b) will
always segfault
Split up the testcases so one failing (in this case en_US.ISO8859-15) won't
cause the rest of the testcases to be skipped
