Previously elfcopy used elf_getdata to obtain data from ELF sections
being copied to binary output, but elf_getdata returns data that has
been translated - that is, data is in host byte order. When the host and
target differ in endianness (e.g., converting a big-endian MIPS ELF
object to binary on an x86 host) this resulted in byte-swapped data in
certain sections such as .dynamic.
Instead use elf_rawdata to keep data in the original, target endianness.

foundation for invoking efibootmgr as part of new-style EFI booting on
x86. On PS3 and PowerNV, which are booted using Linux kexec from petitboot
rather than by loader(8), install the kernel and the rest of /boot to a
FAT partition and set up the appropriate petitboot configuration file
there.
The new bootconfig installer stage can do platform-dependent modifications
more complex than partition layout and installation of boot blocks and can
be used to (as here) set up some special configuration files, run efibootmgr,
or boot0cfg.

This removes the direct WME info access in the ieee80211com struct and instead
provides a method of fetching the data. Right now it's a no-op but eventually
it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm,
upcoming ath10k work) as things like p2p support require this kind of behaviour.
Tested:
* ath(4), STA and AP mode
TODO:
* yes, this is slightly stack size-y, but it is an important first step
to get drivers migrated over to a sensible WME API. A lot of per-phy things
need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up.
The original bug describes it best:
When an absolute time is specified to shutdown, the program's
behavior depends on whether that time has passed during the
current calendar day. POLA would suggest that for shutdown,
whose time argument is always supposed to be in the future,
absolute times specified without a specific date should refer
to the next occurrence of that time, rather than erroring out
if that time has already passed during the current day.

On a load where single anonymous object consumes almost all memory on
the large system, swapout code executes the iteration over the
corresponding object page queue for long time, owning the map and
object locks. This blocks pagedaemon which tries to lock the object,
and blocks other threads in the process in vm_fault() waiting for the
map lock.
Handle the issue by terminating the deactivation loop if we executed
too long and by yielding at the top level in vm_daemon.

is responsible for a very large number of them. In addition, there's a
lot of code that reimplements base FreeBSD functionality, diminishing
the chances it still works. Without hardware to teset it on, or
prospects of obtaining such hardware and without vendor support, it's
time to move on.

it's at least 5 years out of production. I couldn't find a used one on
ebay and other secondary markets just now, nor when I tried 4 years
ago. It dates from the initial project/mips2 merge 8 years ago, and
hasn't been updated since.
Discussed on: mips@ (with some dissent)
It came into the tree with the project/mips merge 8 years ago. At the
time, it was hard to find a board with enough RAM to run. Now FreeBSD
requires at least 2x the RAM it did then. No changes have happened to
this port apart from API churn and license tagging since then. It ran
OK at the time it was committed, but no sightings in the wild have
happened since shortly after it was committed.
https://www.linux-mips.org/wiki/Adm5120_devices lists a bunch of
boards that were available 5 years ago (but are no longer
available). The beefiest one had only 64MB of RAM which is too
small. The Mirktik RB1xx never had more than 32MB.

never got better. It never worked on real hardware and is still mostly
stubs after 8 years when I added it. It has had no real update in that
time apart from API churn. It was added just so it didn't get lost in
the project/mips merge, but maybe it should have been lost as nothing
has come of it. It is time to give up the ghost on this one.

bool indicating whether the input value represents a valid BCD byte.
The existing bcd2bin() routine will KASSERT if asked to convert a bad value,
but sometimes the kernel has to handle BCD data from untrusted sources, so
this will provide a mechanism to validate data before attempting conversion.
This would be have easier/cleaner if the bcd2bin_data[] array contained an
out-of-range value (such as 0xff) in the infill locations that aren't valid,
but it's a global symbol that might be referenced by out-of-tree code
relying on the current scheme, so I'm leaving that alone.
Newer Allwinner SoCs have nearly identical SID controllers with efuse space
starting at 0x200 into their register space and thermal data available at

The h3 will be added at a later time after some testing, due to a silicon

read via the control register.
