Currently the type isn't set in the fbtype struct so any userland

No app that I found find checks the type but at least now it's correct.

Set the bucket size to be SBT_1US/50000 + 1 to be the first number >
20us. I had this uncommitted in my three when I pushed 2283206935
since kern.cam.iosched.bucket_base_us was reporting 19us.
Fixes: 2283206935
Sponsored by: Netflix
Add sysctls to publish the latency bucket size, number, and stride. Move
to putting all the iosched stuff under kern.cam.iosched as well and move
kern.cam.do_dynamic_iosched to kern.cam.iosched.dynamic. In addition, move
kern.cam.io_sched_alpha_bits to kern.cam.iosched.alpha_bits. Publish
kern.cam.iosched.bucket_base (the smallest bucket time), .bucket_ratio
(the geometric progression factor * 100), and .buckets (the total number
of buckets).
Move to publishing 20 buckets, starting at 20us. This allows us to get
better resolution on the short end and detect preformance degredation of
the NVMe drives I've tested on, even with the uncertainty of bucketing.

When a superpage mapping is destroyed and the original page table page
containing 4KB mappings that was being held in reserve is deallocated,
the recently introduced user page table page count was not being
decremented. Consequentially, the count was wrong and would grow over
time. For example, after multiple iterations of "buildworld", I was
seeing implausible counts, like the following:
vm.pmap.kernel_pt_page_count: 2184
vm.pmap.user_pt_page_count: 2280849
vm.pmap.pv_page_count: 106
With this change, I now see:
vm.pmap.kernel_pt_page_count: 2183
vm.pmap.user_pt_page_count: 344
vm.pmap.pv_page_count: 105

Add two underscore characters "__" to names of BIT_* and BITSET_*
macros to move them to the implementation name space and to prevent
a name space pollution due to BIT_* macros in 3rd party programs with
conflicting parameter signatures.
These prefixed macro names are used in kernel header files to define
macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h.
If C programs are built with either -D_KERNEL (automatically passed
when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET
(or this macros is defined in the source code before including the
bitset macros), then all macros are made visible with their previous
names, too. E.g., both __BIT_SET() and BIT_SET() are visible with
either of _KERNEL or _WANT_FREEBSD_BITSET defined.
The main reason for this change is that some 3rd party sources
including sched.h have been found to contain conflicting BIT_*
macros.
As a work-around, parts of shed.h have been made conditional and
depend on _WITH_CPU_SET_T being set when sched.h is included.
Ports that expect the full functionality provided by sched.h need
to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if
BIT_* macros are defined in that program, too.
This patch set makes all of sched.h visible again without this
parameter being passed and without any name space pollution due
to BIT_* macros becoming visible when sched.h is included.
This patch set will be backported to the STABLE branches, but ports
will need to use -D_WITH_CPU_SET_T as long as there are supported
releases that do not contain these patches.

Merge commit df08b2fe8b35 from llvm git (by Dimitry Andric):
[AArch64] Avoid crashing on invalid -Wa,-march= values
As reported in https://bugs.freebsd.org/260078, the gnutls Makefiles
pass -Wa,-march=all to compile a number of assembly files. Clang does
not support this -march value, but because of a mistake in handling
the arguments, an unitialized Arg pointer is dereferenced, which can
cause a segfault.
Work around this by adding a check if the local WaMArch variable is
initialized, and if so, using its value in the diagnostic message.

generic ng_ubt attach causes them to lock up until a power cycle.
However, their firmware interface for querying version info and loading
operational firmware is different from that implemented by ng_ubt_intel
and iwmbtfw, so they are not usable yet. Just disable attach for now to
avoid stalls during USB device enumeration.

When the Verify operation calls nfsv4_loadattr(), it provides
the "struct statfs" information that can be used for doing a
compare for FilesAvail, FilesFree, FilesTotal, SpaceAvail,
SpaceFree and SpaceTotal. However, the code erroneously
used the "struct nfsstatfs *" argument that is NULL.
This patch fixes these cases to use the correct argument
structure. For the case of FilesAvail, the code in
nfsv4_fillattr() was factored out into a separate function
called nfsv4_filesavail(), so that it can be called from
nfsv4_loadattr() as well as nfsv4_fillattr().
In fact, most of the code in nfsv4_filesavail() is old
OpenBSD code that does not build/run on FreeBSD, but I
left it in place, in case it is of some use someday.
I am not aware of any extant NFSv4 client that does Verify
on these attributes.

relocates ifnet between vnets and changes if_index. Since if_index
changes, nhop hash values also changes, unlink_nhop() isn't able to

the latter is also leaked. As result running network tests leaks
