that is #if 0'd and (still) has never been compiled (most likely
never will be.)
While here, in the same uncompiled code, deal with line number
counting. Whether this is correct depends upon how this code
is used, and as it never is (and never has been since line numbers
first started being counted), this is somewhat speculative, but
it seems likely to be the correct way to handle things.
NFC (this code is still all #if 0).
should be looked up as a potential following alias - if the first
expands to a string that ends with a space (any space, quoted or
not) then the next word is to be treated as an alias candidate.
(POSIX was to specify only unquoted spaces, but is now going to
leave that unspecified, and the "any space" version turns out to
be more useful.
And besides, the quoteflag test didn't work properly, and would
have been very messy to fix ... if in a word (as if we have a
quoted space) it means that the word has been quoted, which meant
that quoted spaces were correctly detected, but it outside a word,
it just means that the previous word was quoted, so it would sometimes
reject alias lookup on the next word in cases where it is unquestioned
it should be done.
so the fake char returned by the latter when an alias ends (which
is there so we can correctly avoid alias recursion) is correctly
ignored where it is not wanted.
line that needed wrapping so it no longer does, and is (IMO) clearer.
WHile here, note that this was created in 2019, not 2018, for the

- local IPL_NONE mutex for general pmap locking operations, not
kernel lock.
- for pmap_activate()/pmap_deactivate(), switch to using the
existing ctx_lock, and push handling of it into ctx_alloc() the
ctx_free() callers.
fixes easy to trigger deadlocks on systems with >2 cpus. without
this patch i usually hang during boot. with it, i was able to
push the machine hard for over 12 hours.
XXX: pullup-8, and maybe -7.
expected failure referencing PR kern/53865, and force failure to avoid
reports of unexpected success as it does not realiably fail under
qemu. This makes the treatment of udf_renamerace_dirs the same as
that of udf_renamerace, only with a different PR. Also, make
whitespace consistent between the two.
means that the guest pages that are WC+ become CD, and this degrades
performance of the guests.
Explicitly enable WC+.
While here clarify the AMD identification code.
when it is executing as part of the lib/libc/sys/t_ptrace_waitid test,
because that particular combination is not failing, at least not on amd64.
It is failing as part of other tests, so PR lib/53343 still applies.
off chance it failed, there's still the possibility that whatever
processes the result will be able to deal with the %m that would
(presumably) be left in the format string.
And as a frill, don't call strerror() until we know we are
going to use its result (still call it only once, no matter
how many %m's are in the format string).
