7023544aec Workaround Spectre Variant 2 on arm64.
We need to handle two cases:

1. One process attacking another process.
2. A process attacking the kernel.

For the first case we clear the branch predictor state on context switch
between different processes. For the second we do this when taking an
instruction abort on a non-userspace address.

To clear the branch predictor state a per-CPU function pointer has been
added. This is set by the new cpu errata code based on if the CPU is
known to be affected.

On Cortex-A57, A72, A73, and A75 we call into the PSCI firmware as newer
versions of this will clear the branch predictor state for us.

It has been reported the ThunderX is unaffected, however the ThunderX2 is
vulnerable. The Qualcomm Falkor core is also affected. As FreeBSD doesn't
yet run on the ThunderX2 or Falkor no workaround is included for these CPUs.

2e07e232a2 Add a hack to disable AUTO_OBJ for 'old style' kernel builds.
Another solution would be to extend the Makefile.sys.inc idea, or a .no_obj
file, to more places but I would rather keep that limited to the top-level
build for now to not impact performance (statting a file in every make call)
or to bring unintended side-effects.

ce076a1f58 Ensure that the vnet is set when calling pru_sockaddr() and
pru_peeraddr().

This is already true when called via kern_getsockname() and
kern_getpeername(). This patch sets it also, when they arecalled
via soo_fill_kinfo(). This is necessary, since the corresponding
functions for SCTP require the vnet to be set. Without this,
if a process having an wildcard bound SCTP socket is
terminated and a core is written, the kernel panics.

21ab148d78 patch(1): Don't check for NUL bytes in Plan A
Plan A mmap()'s the entire input file and operates on it in memory. The
map(2) call succeeded, so we shouldn't need to bother checking for the NUL
byte as long as we're within our buffer space.

This was clearly intentional to match "the behavior of the original code",
but it creates a discrepancy between Plan A and Plan B that doesn't seem
sensible and it's not inherently wrong to allow a NUL byte.

This change was motivated by the gemspec in net/rubygem-grpc failing to
patch, despite the patch being generated with diff, because a NUL byte was
used as a delimiter in the header briefly in an otherwise text file.

An alternative was considered: to fallback to plan B if plan A won't process
the entire file due to a NUL byte, but I deemed this to be the better option
since plan A isn't failing due to memory limitations and will fail later on
if it's really dealing with a file it shouldn't be.

767754e5ab if_awg: Support new emac bindings
Highlights of the new bindings:
- ahb clock is specified as 'stmmaceth'
- The PHY to be used is now specified as phy-handle
- We must now check the parent of the node phy-handle points to in order to
discover if we're using internal PHY.
- The ephy clk/reset will be specified on the PHY node, not the emac node.

Care has been taken to ensure that we remain compatible with the older
bindings that we were previously using.

973c4efb9d Enable ld.lld as bootstrap linker by default on i386
Akin to r327783 for amd64.  lld has been usable for amd64 for quite some
time, but a couple of issues remained that affected i386.  These were
recently addressed upstream in lld and merged into FreeBSD (r326831,
r326879, r326897, r326957), so we can now use ld.lld on i386 as well.

Similarly to amd64 this change enables lld only as the bootstrap linker
(used to link the kernel and userland libraries and executables), while
GNU ld.bfd is still installed as /usr/bin/ld and used for ports builds.

The ports collection is essentially ready to use lld as the system
linker for amd64, but many ports still have trouble with lld on i386,
because lld defaults to -ztext, disallowing relocations against readonly
segments.  Thus switching the system linker (WITH_LLD_IS_LD) will happen
later on a per-arch basis.
