the change was merged to stable branches breaking ABI there, too.

In r367327 generic_bs_sr_<n> were derived from mips. Given we are calling
generic_bs_w_<n> and no write directly, we do not have to do the address
calculations ourselves as eneric_bs_w_<n> will do a str val [bsh, offset].
All we actually have to do is increment offset.

There are workloads with very bursty tid allocation and since unr tries very
hard to have small-sized bitmaps it keeps reallocating memory. Just doing
buildkernel gives almost 150k calls to free coming from unr.
This also gets rid of the hack which tried to postpone TID reuse.

The intent is to replace the current id allocation method and a known upper

The HPT is always stored in big-endian, as it is accessed directly by the
hardware as well as the kernel. As such, it is necessary to convert values
to and from native endian when running on LE.
Some unconverted accesses snuck in accidentally with r367417.
Apply the appropriate conversions to fix boot hanging on powerpc64le.

Currently there is no locking done to protect this structure. It is
likely okay due to the low-volume nature of IGMP, but allows for
the possibility of underflow. This appears to be one of the only
holdouts of the conversion to counter(9) which was done for most
protocol stat structures around 2013.
This also updates the visibility of this stats structure so that it can
be consumed from elsewhere in the kernel, consistent with the vast
majority of VNET_PCPUSTAT structures.

The goal of the fib support is to provide multiple independent
routing tables, isolated from each other.
net.add_addr_allfibs default tries to shift gears in the opposite
direction, unconditionally inserting all addresses to all of the fibs.
There are use cases when this is necessary, however this is not a
default expected behaviour, especially compared to other implementations.
Provide WARNING message for the setups with multiple fibs to notify
potential users of the feature.

- map those IPv4 / IPv6 socket options which exist in FreeBSD
+ most of them visually verified to have the same type/layout of arguments
+ not tested with linux programs to behave as intended
- be more human readable for known options which are not handled
- be more verbose for unhandled socket message flags we know about
- print the jail ID in linux_msg if run in a jail
- add possibility to print debug message about known missing parts only once
- add multiple levels of sysctl linux.debug:
1: print debug messages, tell about unimplemented stuff (only once)
2: like 1, but also print messages about implemented but not tested
stuff (only once)
3+: like 2, but no rate limiting of messages
- increase default linux debug level from 1 to 3
We are a lot more verbose in as we need to be (e.g. some of the IP socket
options which are the same, and share the same memory layout, and are
believed to work). The reason is that we have no good testsuite to test those
linux-bits. The LTP or other test suites like the python one, are not fully
up to the task we need. As such the excessive messages about emulated but not
tested socket options.
IMO any MFC (possible, but most probably not by me) should set the default
debug level to 1.

imgact_binmisc matches magic/mask from imgp->image_header, which is only a
single page in size mapped from the first page of an image. One can specify
an interpreter that matches on, e.g., --offset 4096 --size 256 to read up to
256 bytes past the mapped first page.
The limitation is that we cannot specify a magic string that exceeds a
single page, and we can't allow offset + size to exceed a single page
either. A static assert has been added in case someone finds it useful to
try and expand the size, but it does seem a little unlikely.
While this looks kind of exploitable at a sideways squinty-glance, there are
a couple of mitigating factors:
1.) imgact_binmisc is not enabled by default,
2.) entries may only be added by the superuser,
3.) trying to exploit this information to read what's mapped past the end
would be worse than a root canal or some other relatably painful
experience, and
4.) there's no way one could pull this off without it being completely
obvious.
The first page is mapped out of an sf_buf, the implementation of which (or
lack thereof) depends on your platform.

Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected. Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.
The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers. The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens. Other versioning
schemes are possible in future, because the format is unspecified.
