Places that will wait for curproc->p_singlethr to become zero (in the
next commit, the counter of number of external single-threading is
to be introduced), must wait for it interruptible, otherwise we
deadlock. On the other hand, a signal delivered during this window,
if directed to the waiting thread, would cause the wait loop to become
a busy loop.
Since we are exiting, it is safe to ignore the signals.

Addition to D31491 in order to actually resolve the top root cause.
Currently rpcbind gets contact address from connectionless xprt->xp_p2
member of a transport and will fail to get it when working over
connection oriented transport, leading to a guess game in terms of
contact address on rpcinfo requests like RPCBPROC_GETVERSADDR or
RPCBPROC_GETADDRLIST and poor returns which may influence a user
of a call and specifically reported on OSX clients, which tend to
not provide address hint from rpcinfo request to a server.

Install the i386 md_var.h under /usr/include/i386 on amd64 and include

Install the i386 pcpu.h under /usr/include/i386 on amd64 and include

This is a kernel-only header and should not be required, but
procstat's zfs support includes this with _KERNEL defined.
Reviewed by: jhb, imp
The contents of the amd64 version are kernel-only and incompatible with
other headers when compiled for i386 userspace with _KERNEL defined.
Just ifdef the whole file out in that case rather than giving this file
the full x86 treatment since it's not needed for current use cases
(procstat zfs support).

By creating an i386 symlink, this allows code compiled with -m32 to
build (32-bit vdso and linux bits) when -m32 support requires files
in the i386 hierarchy.
Reviewed by: jhb, imp
This directory will hold i386-specific headers that are needed for
-m32 support on amd64 and where the amd64 and i386 cases have too
little in common for combining them to make sense. Files to be
installed will come in later commits.
With the currently required set of files, this could be done with
another INCGROUP in include/Makefile, but at least one file that
might want -m32 support (ieeefp.h) conflicts with a files installed
in /usr/include.

In lacp_select_tx_port_by_hash(), we assert that the selected port is
DISTRIBUTING. However, the port state is protected by the LACP_LOCK(),
which is not held around lacp_select_tx_port_by_hash(). So this
assertion is racy, and can result in a spurious panic when links
are flapping.
It is certainly possible to fix it by acquiring LACP_LOCK(),
but this seems like an early development assert, and it seems best
to just remove it, rather than add complexity inside an ifdef
INVARIANTS.

Split the driver up into two modules (if_rtw88_pci.ko and rtw88_core.ko).
This is in preparation for the hopefully eventually upcoming USB support
using the same driver core.
Note: this changes the module name to load to if_rtw88_pci.ko instead of
if_rtw88.ko. If using devmatch(8) everything should stay the same as
the driver name (used for net.wlan.devices) stays rtw88. If using
kld_list in rc.conf or loader.conf you will need to adjust the name.

One of the checks was that the cylinder group size (fs_cgsize)
matched that calculated by CGSIZE(). The value calculated by CGSIZE()
has changed over time as the filesystem has evolved. Thus comparing
the value of CGSIZE() of the current generation filesystem may not
match the size as computed by CGSIZE() that was in effect at the
time an older filesystem was created. Therefore the check for
fs_cgsize is changed to simply ensure that it is not larger than
the filesystem blocksize (fs_bsize).

A problem which showed up on 13.1 between BETA3 and RC1 was that on older
chipsets the fw would crash. While some 0x18 ADD_STA problems were seen
before, d9f59799fc was the actual trigger for this problem
(in 0x28 MAC_CONTEXT command) in a squashed merge to the releng branch.
Strangely there were no changes to assoc_to_run in that revision so other
circumstances may be the actual cause but swapping the bss_info update and
the sta_state in that function seem to make my 8265 happy while AX200 and
AX210 stay good.
Thanks to everyone who helped debug this.

This update does not contain any functional change, but fixes two
minor build issues:
- Temporary files were created in the source directory, causing build
failures if the sources were not writable at build time.
- A message catalogue contained extra characters that were ignored but
made gencat print warning messages.
This version adds support for command line editing and history using
the editline or readline libraries in addition to the line editing
features available in previous versions.
In RB_NEXT, when there is no RB_RIGHT node, the search must proceed
through the parent node.
There is code written to handle the case when the parent is non-NULL
and the current element is the left child of that parent. If you
assume that the current element is either the left child of its
parent, or the right child of its parent, but not both, then this test
is not necessary. Instead of assigning RB_PARENT(elm, field) to elm
when elm == RB_LEFT, removing the test has the code assign
RB_PARENT(elm, field) to elm when elm != RB_RIGHT. There's no need to
examine the RB_LEFT field at all.
This change removes that needless RB_LEFT test, and makes a similar
change to the RB_PREV implementation.

Rework the way we are dealing with the last queue. If the driver
opts in to STA_MMPDU_TXQ then preferably send all non-data frames
via the last (IEEE80211_NUM_TIDS) queue which otherwise is not used
in station mode.
If we do not have that queue we do individual tx() calls for non-data
frames now.
Everything else goes via the selected queue if possible for as long as
we have a ni (sta) and otherwise resorts to direct tx.
