f0188618f2 Fix multiple incorrect SYSCTL arguments in the kernel:
- Wrong integer type was specified.

- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.

- Logical OR where binary OR was expected.

- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.

- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.

- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.

- Updated "EXAMPLES" section in SYSCTL manual page.

a5045426db Fix a race in pmap_emulate_accessed_dirty() that could trigger a EPT
misconfiguration VM-exit.

An EPT misconfiguration is triggered when the processor encounters a PTE
that is writable but not readable (WR=10). On processors that require A/D
bit emulation PG_M and PG_A map to EPT_PG_WRITE and EPT_PG_READ respectively.

If the PTE is updated as in the following code snippet:
	*pte |= PG_M;
	*pte |= PG_A;
then it is possible for another processor to observe the PTE after the PG_M
(aka EPT_PG_WRITE) bit is set but before PG_A (aka EPT_PG_READ) bit is set.

This will trigger an EPT misconfiguration VM-exit on the other processor.

timecounter resolution is available, so ask for a 1 GHz frequency.  It
won't actually get one that fast, but that'll get the fastest available

e011dc962c Merge from projects/bhyve_svm all the changes outside vmm.ko or bhyve utilities:
Add support for AMD's nested page tables in pmap.c:
- Provide the correct bit mask for various bit fields in a PTE (e.g. valid bit)
  for a pmap of type PT_RVI.
- Add a function 'pmap_type_guest(pmap)' that returns TRUE if the pmap is of
  type PT_EPT or PT_RVI.

Add CPU_SET_ATOMIC_ACQ(num, cpuset):
This is used when activating a vcpu in the nested pmap. Using the 'acquire'
variant guarantees that the load of the 'pm_eptgen' will happen only after
the vcpu is activated in 'pm_active'.

Add defines for various AMD-specific MSRs.

0067051fe7 Fully support constructors for the purpose of code coverage analysis.
This involves:
1.  Have the loader pass the start and size of the .ctors section to the
    kernel in 2 new metadata elements.
2.  Have the linker backends look for and record the start and size of
    the .ctors section in dynamically loaded modules.
3.  Have the linker backends call the constructors as part of the final
    work of initializing preloaded or dynamically loaded modules.

Note that LLVM appends the priority of the constructors to the name of
the .ctors section. Not so when compiling with GCC. The code currently
works for GCC and not for LLVM.

007054f070 Add vxlan interface
vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in
a UDP packet. This implementation is based on RFC7348.

Currently, the IPv6 support is not fully compliant with the specification:
we should be able to receive UPDv6 packets with a zero checksum, but we
need to support RFC6935 first. Patches for this should come soon.

Encapsulation protocols such as vxlan emphasize the need for the FreeBSD
network stack to support batching, GRO, and GSO. Each frame has to make
two trips through the network stack, and each frame will be at most MTU
sized. Performance suffers accordingly.

Some latest generation NICs have begun to support vxlan HW offloads that
we should also take advantage of. VIMAGE support should also be added soon.
