This option was not tested when WARNS was globally lifted in the src tree up
to 6. Drop WARNS back down to unbreak the build; note that this is still
enabling more warnings than it had before the WARNS change, so the gcc build
may need to be independently evaluated at this level.

All page zeroing is using temporal stores with rep movs*, the routine is
unused for several years.
Should a need arise for zeroing using non-temporal stores, a more
optimized variant can be implemented with a more descriptive name.
The previous code neglected to use primitives which can find the end
of the string without having to branch on every character.
While here augment the somewhat misleading commentary -- strlen as
implemented here leaves performance on the table, especially so for
userspace. Every arch should get a dedicated variant instead.
In the meantime this commit lessens the problem.
Tested with glibc test suite.

The initial plan was to remove rib_lookup_info() before
FreeBSD 13. As several customers are still remaining,
fix rib_lookup_info() for the multipath use case.
D26436 introduced support for stacked vlans that changed the way vlans
are configured. In particular, this change broke setups that have
same-number vlans as subinterfaces.
Vlan support was initially created assuming "vlanX" semantics. In this paradigm,
automatic number assignment supported by cloning (ifconfig vlan create) was a
natural fit.
When "ifaceX.Y" support was added, allowing to have the same vlan number on
multiple devices, cloning code became more complex, as the is no
unified "vlan" namespace anymore. Such interfaces got the first spare
index from "vlan" cloner. This, in turn, led to the following problem:
ifconfig ix0.333 create -> index 1
ifconfig ix0.444 create -> index 2
ifconfig vlan2 create -> allocation failure
This change fixes such allocations by using cloning indexes only for
"vlanX" interfaces.

Originally IFCAP_NOMAP meant that the mbuf has external storage pointer
that points to unmapped address. Then, this was extended to array of
such pointers. Then, such mbufs were augmented with header/trailer.
Basically, extended mbufs are extended, and set of features is subject
to change. The new name should be generic enough to avoid further
renaming.
- Use libelf to parse ELF data structures and remove code duplication
for ELF32.
- Don't require the OSABI field to be set to the FreeBSD OSABI for
shared libraries. Both AArch64 and RISC-V leave it set to "none"
and instead depend on the ABI tag note. For ldd, this means falling
back to walking the notes in PT_NOTE segments to find the ABI tag
note to determine if an ELF shared library without OSABI set in the
header file is a FreeBSD shared library.

This reverts commit fcb4797c90.
With `CIRRUS_CLONE_DEPTH` unspecified (using the default of 50) the
time to clone the repo increased from a little under 2 minutes to over
6 minutes, possibly due to additional processing required by GitHub.
We will want to watch out for occasional `Failed to force reset to
SHA: object not found!` errors.
Previously Cirrus was skipped on svn_head to avoid running CI on two
different branches with identical content. With the transition to git
this serves no purpose.

There's a currently ad-hoc protocol to hand off the FreeBSD kernel
payload between the loader and the kernel itself when Xen is in the
middle of the picture. Such protocol wasn't very resilient to changes
to the loader itself, because it relied on moving metadata around to
package it using a certain layout. This has proven to be fragile, so
replace it with a more robust version.
The new protocol requires using a xen_header structure that will be
used to pass data between the FreeBSD loader and the FreeBSD kernel
when booting in dom0 mode. At the moment the only data conveyed is the
offset of the start of the module metadata relative to the start of the
module itself.
This is a slightly disruptive change since it also requires a change
to the kernel which is contained in this patch. In order to update
with this change the kernel must be updated before updating the
loader, as described in the handbook. Note this is only required when
booting a FreeBSD/Xen dom0. This change doesn't affect the normal
FreeBSD boot protocol.
This fixes booting FreeBSD/Xen in dom0 mode after
3630506b9d.

This follows select by eleminating the use of filedesc lock.
This is a win for single-threaded processes and a mixed bag for others
as at small concurrency it is faster to take the lock instead of
refing/unrefing each file descriptor.
Nonetheless, removal of shared lock usage is a step towards a
mtx-protected fd table.
Since most select users are single-threaded this avoid a lot of work
in the common case.
For example select of 16 fds (ops/s):
before: 2114536
after: 2991010
This can be used by single-threaded processes which don't share a file
descriptor table to access their file objects without having to
reference them.
For example select consumers tend to match the requirement and have
several file descriptors to inspect.
This tests fork()s, so if there is still data in the stdout buffer on fork
it will print it again in the child process. This was happening in the
CheriBSD CI and caused the test to complain about malformed TAP output.

vfs_cache_lookup() has already done the appropriate VEXEC check, therefore
we must not re-check in VOP_CACHEDLOOKUP.

Three changes to make uname more useful.
1. Move from using git rev-list --count to git rev-lis --count --first-parent
since that gives a better, incrementing number.
2. Report this count as 'nXXXXX' rather than 'cXXXXX' because c is part of
a hash and we've changed the sematnics of XXXXX
3. Remove g to make HASH cut and pastable.

When reading the PCI config. space behind the VMD controller,
the offset of the starting bus needs to be subtracted from
the bus being read.
Fixed a bug in which in which not all of the devices
directly attached to the VMD controller would be probed.
On my initial test HW, a switch was found at bus 0, slot 0
and function 0. All of the NVME drives were behind that
switch. Now scan for all slots and functions attached to
bus 0. If a something was found then run attach after the
