Currently we pass the raw pointer to the on-stack auxargs. This can
legitimately have fewer than AT_COUNT entries, so the use of
__min_size(AT_COUNT), i.e. static AT_COUNT, is inaccurate, and also
needlessly forces the callee to iterate over the elements to find the
entry for a given type. Instead we can just pass aux_info like we use
for everything else.
Note that the argument has been left unused by every callee since its
introduction in 4352999e0e ("Pass CPUID[1] %edx (cpu_feature), %ecx
(cpu_feature2) and CPUID[7].%ebx (cpu_stdext_feature), %ecx
(cpu_stdext_feature2) to the ifunc resolvers on x86.")

Don't provide default linkage for jemalloc 3.0 compatability symbols.
We stopped declaring these interfaces with the introduction of jemalloc
4.0 prior to FreeBSD 11.0. Any code using them would have had to
declare them manually so stop declaring them and export the symbols
directly for compatability. Arguably they should be x86 only as they
were never declared on other Tier-1 architectures.

While this won't be noticed by most users the time to zero the bss
while using instruction tracing in the Arm FVP models (simulators) is
noticeable.
Reduce this time by using a store-pair instruction to double the size
of memory we zero on each iteration of the loop.

* We can build the non-VHE code with branch protection, it is already
build as such in the module.
* Use the correct file name for the non-VHE exception .o file.
When FEAT_VHE is present the HCR_EL2 E2H field will be implemented. Try
setting this and checking if it's still set to decide if we can boot
into VHE mode or not.
When it is implemented the kernel will boot into EL2 rather than EL1
it currently boots to. The parts of the kernel that need to know if
they are in EL1 or EL2 have been updated other than the CoreSight
driver as there doesn't appear to be any way to currently use it and
it will be updated soon with the new HWT framework.

RFC8275 defines a new attribute as an extension to NFSv4.2
called MODE_UMASK. This patch adds support for this attribute
to the NFSv4.2 client and server.
Since FreeBSD applies the umask above the VFS/VOP layer,
this attribute does not actually have any effect on the
handling of ACL inheritance, which is what it is designed for.
However, future changes to NFSv4.2 require support of it,
so this patch does that, resulting in behaviour identcal to
the mode attribute already supported.

A number of people have reported panics with it enabled by default,
possibly due to broken ACPI tables, which we do not handle well. D46382
is a potential fix for this issue.
Additionally DMAR is currently not compatible with bhyve passthrough
(see comment #10 in PR280817), with a draft patch to address that in
D25672.
Revert to disabling DMAR by default pending the resolution of those two
issues.
