Current way, hardcoded value plus heuristic is not conform to the PCI(e)
specification and it fails on systems where MSI-X bar is not initialized by
BIOS/ACPI (many arm or arm64 systems for example).
Instead, use the standard PCI(e) capability for determining of
MSIX table bar address.

One of the disadvantages of our current busdma code is the fact that
we process the bounced buffer in a page-by-page manner. This means that
the short (subpage) buffer allocated across page boundaries is bounced
to 2 separate pages.
This suboptimal behavior is consistent across all platforms and can be
related to (probably unimplementable or incompatible with bouncing)
BUS_DMA_KEEP_PG_OFFSET flag.
Therefore, allocate one additional page to be fully comply with this
requirement.

- Use a uintptr_t cast to get the virtual address of a pointer in
USB_P2U() instead of a ptrdiff_t.
- Add offsets to a char * pointer directly without roundtripping the

The sense_ptr thing is quite broken. As near as I can tell, the
driver tries to copyout to a physical address rather than whatever
user address the sense buffer should be copied to. It is not
immediately obvious what user address the sense buffer should be
copied to.

GDB 6.1.1 was released in June 2004 and is long obsolete. It does not
support all of the architectures that FreeBSD does, and imposes
limitations on the FreeBSD kernel build, such as the continued use of
DWARF2 debugging information.
It was kept (in /usr/libexec/) only for use by crashinfo(8), which
extracts some basic information from a kernel core dump after a crash.
Crashinfo already prefers gdb from port/package if installed.
Future work may add kernel debug support to LLDB or find another path
for crashinfo's needs, but in any case we do not want to ship the
excessively outdated GDB in FreeBSD 13.

When r362031 moved local TLB invalidation after shootdown IPI send, it
moved too much. In particular, PCID-mode clearing of the pm_gen
generation counters must occur before IPIs are send, which is in fact
described by the comment before seq_cst fence in the invalidation
functions.
Fix it by extracting pm_gen clearing into new helper
pmap_invalidate_preipi(), which is executed before a call to
smp_masked_tlb_shootdown().
Rest of the local invalidation callbacks is simplified as result, and
become very similar to the remote shootdown handlers (to be merged in
some future).
Move pin of the thread to pmap_invalidate_preipi(), and do unpin in
smp_masked_tlb_shootdown().

Ability to load-balance traffic over multiple path is a must-have thing for routers.
It may be used by the servers to balance outgoing traffic over multiple default gateways.
The previous implementation, RADIX_MPATH stayed in the shadow for too long.
It was not well maintained, which lead us to a vicious circle - people were using
non-contiguous mask or firewalls to achieve similar goals. As a result, some routing
daemons implementation still don't have multipath support enabled for FreeBSD.
Turning on ROUTE_MPATH by default would fix it. It will allow to reduce networking
feature gap to other operating systems. Linux and OpenBSD enabled similar support
at least 5 years ago.
ROUTE_MPATH does not consume memory unless actually used. It enables around ~1k LOC.
It does not bring any behaviour changes for userland.
Additionally, feature is (temporarily) turned off by the net.route.multipath sysctl
defaulting to 0.

The ARM PMU may use single per-core interrupt or may use multiple generic
interrupts, one per core. In this case, special attention must be paid to
the correct identification of the physical location of the core, its order
in the external database (FDT) and the associated cpuid.
Also keep in mind that a SoC can have multiple different PMUs
(usually one per cluster)
Some older PSCI implementations corrupt (or do not pass) the context_id
argument to newly started secondary cores. Although the ideal solution to this
problem is u-boot update, we can find the correct value for the argument (cpuid)
by comparing of real core mpidr register with the value stored in pcu->mpidr.

Without this we risk having the .interp section be placed earlier in the
file and mess with section offsets; in particular it has been seen to be
placed at the start of the file and cause the PE/COFF header to not be
at address 0. This is the same fix as was done for arm64 in r365578.
