1. Add a reference to a good 3rd party list of compatible cables, but
provide suggestions for 'known good' vendors.
2. Change IP-based USB host-host example to a modern Ethernet one which
works 'out of box' with current Linux systems.
3. Explain that USB 3.0 is host-host, even though point-to-point soft
Ethernet can be achieved.

VBAD type.
FFS ffs_write() VOP catches such vnodes and panics, other VOPs do not
check for the type and their behaviour is really undefined. The
comment claims that this support was done for 'badsect' to flag bad
sectors, we do not have such facility in kernel anyway.

AArch64: account for possible frame index operand in compares.
If the address of a local is used in a comparison, AArch64 can fold
the address-calculation into the comparison via "adds".
Unfortunately, a couple of places (both hit in this one test) are not
ready to deal with that yet and just assume the first source operand
is a register.
This should fix an assertion failure while building the test suite of
www/firefox for AArch64.

This catches some rare mysterious failures at the source. The check
is only performed on architectures which implement direct map, and
only enabled with option DIAGNOSTIC, similar to other costly
consistency checks.

- Teach elf aux vector functions about newly added AT_HWCAP and AT_HWCAP2
vectors.
- Export _elf_aux_info() as new public libc function elf_aux_info(3)
The elf_aux_info(3) should be considered as FreeBSD counterpart of glibc
getauxval() with more robust interface.
Note:
We cannot name this new function as getauxval(), with glibc compatible
interface. Some ports autodetect its existence and then expects that all
Linux specific AT_<*> vectors are defined and implemented.

HEAD. Enable VIMAGE in GENERIC kernels and some others (where GENERIC does
not exist) on HEAD.
Disable building LINT-VIMAGE with VIMAGE being default.
This should give it a lot more exposure in the run-up to 12 to help
us evaluate whether to keep it on by default or not.
We are also hoping to get better performance testing.
The feature can be disabled using nooptions.

The end of the loop must re-lookup the next buf since the bufobj lock
is dropped in the loop body. If the lookup fails, the loop is restarted.
This mechanism non-obviously also terminates the loop when the end of
the buf list is reached. Split up the two loops termination cases to
make the code a bit less fragile. No functional change intended.

If filesystem block size is less than the page size, it is possible
that the page-out run contains partially clean pages. E.g., the chunk
of the page might be bdwrite()-ed, or some thread performed bwrite()
on a buffer which references a chunk of the paged out page. As
result, the assertion added in r319975, which checked that all pages
in the run are dirty, does not hold on such filesystems.
One solution is to remove the assert, but it is undesirable, because
we do overwrite the valid on-disk content. I cannot provide a scenario
where such write would corrupt the file data, but I do not like it on
principle. Another, in my opinion proper, solution is to only write
parts of the pages still marked dirty. The patch implements this, it
skips clean blocks and only writes the dirty block runs.
Note that due to clustering, write one page might clean other pages in
the run, so the next write range must be calculated only after the
current range is written out.
More, due to a possible invalidation, and the fact that the object
lock is dropped and reacquired before the checks, it is possible that
the whole page-out pages run appears to consist of only clean pages.
For this reason, it is impossible to assert that there is some work
for the pageout method to do (i.e. assert that there is at least one
dirty page in the run). But such clearing can only occur due to
invalidation, and not due to a parallel write, because we own the
vnode lock exclusive.
