These quirks are intended for optimizing CPU performance, not for
applying errata workarounds. Nobody can expect that CPU with unfixed
errata is stable enough to execute the kernel until quirks are applied.

This change is a portion of LLD rev 305212 which accidentally ended
up in my svn tree. We do want to backport the change to LLD 4.0, but
it needs additional work and was not supposed to be included in
r319887.
It appears that the same arches that lack GENERIC kernel configs also lack
LINT. But enough different arches get built to ensure a kernel change
should build everywhere (32 and 64 bit, clang and old gcc, little and big
endian).
Right now the driver only supports port VLANs, so make sure
etherswitch_getinfo() return the proper switch capabilities.
Handle the cases where not all ports are in use (that will also require
etherswitch cooperation).

If two sections contained relocations to absolute symbols with the same
value we would crash when trying to access their sections. Add a check that
both symbols point to sections before accessing their sections, and treat
absolute symbols as equal if their values are equal.

struct thread.
For all architectures, the syscall trap handlers have to allocate the
structure on the stack. The structure takes 88 bytes on 64bit arches
which is not negligible. Also, it cannot be easily found by other
code, which e.g. caused duplication of some members of the structure
to struct thread already. The change removes td_dbg_sc_code and
td_dbg_sc_nargs which were directly copied from syscall_args.
The structure is put into the copied on fork part of the struct thread
to make the syscall arguments information correct in the child after
fork.
This move will also allow several more uses shortly.

Based on feedback from OpenZFS developers Matt Ahrens and George Wilson,
the calculation of the ratio no longer takes in to account overhead.
The old formula could result in reporting a negative compression ratio
This could confuse the user or give a false impression that there would be
an advantage to disabling the compressed ARC feature.
The new formula will more closely match an average of the on-disk
compression ratio, as reported by the ZFS property 'compressratio'

Use a similar approach to r318957 (which was for ptrace dependencies):
grep the .depend file for the old source file and delete the stale
dependency if found.

This uses a hack to get the CMD from the meta file rather than

just the GENERIC kernels for each arch (including variations such as
GENERIC-NODEBUG, GENERIC64, etc).
This helps with quickly doing a test build for all[*] arches without
building dozens of variant kernels for the arches that have lots of
hardware/board/system variations.
[*] Not all arches have a generic kernel (but they probably should for
test-building purposes, even if it can't boot on any real hardware).
The testcase fails today, so mark it with atf_expect_fail: in
particular, the target (B) isn't being unlinked and the documentation
doesn't suggest special handling for directories. Thus, there's either
a doc or an implementation bug in ln(1) that needs to be resolved.

After r319369, the RPC code validates caller supplied buffer length in
taddr2uaddr. When no -h is specified, the sizeof(ai_addr) is used,
which is always smaller than the required size and therefore uaddr
would be NULL, causing the kernel to copyin() from userland NULL
and fail with EFAULT.

A previous iteration of the tests I added in r319844 involved free(3), but
that attempt didn't pan out, so I switched to stack allocated buffers instead

Testcases for -H, -L, and -f haven't been implemented yet, in part due
to additional complexity needed to validate the features:
* -H and -f will require an external "helper" program to display/modify

* -L is being covered partially via the -n testcase today.
