31fc9817bb Split the local disk availability step into two phases to allow scripts 
that pre-populate parts of the system (e.g. a tmpfs based /var) an
easy place to plug in like:

# REQUIRE: mountcritlocal
# BEFORE: MOUNTCRITLOCAL

This also cleans up the existing special handling a bit by separating it
into new scripts. All later scripts now depend on MOUNTCRITLOCAL.
Discussed on tech-userlevel some time ago.

e6ac0f80fe Skip interfaces that are already UP before the test starts. We can 
not change state of the test host this way, it breaks e.g. test systems
with the root filesystem on NFS.

a218bd8f70 make(1): remove parameter from ModifyWordCallback 
Most modifiers don't need a variable context, and those that do already
get all their parameters in a custom Args struct.

d5de9f10d7 make(1): add test for :S,,sep 
The empty string does not match anywhere.  In other implementations of
string replacement, an empty string matches at every position of the
source string.

This only works for the :S modifier.  The :C modifier does not allow an
empty search pattern.

011db151f6 make(1): only ask for newline if :Q actually needs it 
This simple change reduces the binary size of var.o by 96 bytes (Clang,

order, this is a bit surprising.

95ed12b952 wpa_supplicant: Matching unspecified interfaces should not log driver fails 
If there is no matching interface given, but interface matching is enabled
then all interfaces on the system will try to be initialized.

Non wireless interfaces will fail and the loopback device will be one
of these, so just log a diagnostic rather than an error.

dad129c1ca wpa_supplicant: don't log SIOCG80211 errors during interface setup

wpa_supplicant will log it failed to initialized the driver for the

87dfc27289 Align tmpstk to 4-byte boundary in the same manner as mac68k. 
However, unfortunately, this does not fix strange crashes of GCC8-compiled
kernel, for which I cannot even enter DDB nor obtain crash dump.

We need further investigation...

f0f5c33535 For GCC8, do not omit frame pointer for intr_dispatch() and via1_intr() 
(-fomit-frame-pointer is enabled for -O and higher for GCC8).

This is required by rtclock_intr() which unwinds stack frame of caller!

XXXXXX
We need to get rid of this hackest hack for rtclock_intr(). This problem
was discussed back in 2014:

http://mail-index.netbsd.org/port-mac68k/2014/08/15/msg000595.html
http://mail-index.netbsd.org/port-mac68k/2014/08/17/msg000600.html
http://mail-index.netbsd.org/port-mac68k/2014/08/17/msg000601.html

However, unfortunately, the problem has been left untouched until today.

The patch attached in the third message works around the problem. But,
it adds hard-coded magic numbers to intr_dispatch() and via1_intr().
For real fix, we should probably reconsider whole interrupt handling.

Anyway, now kernel compiled by GCC8 works fine as far as I can see.

e7adb96342 make(1): fix edge cases with $ at the end of the :@ modifier 
In both parts of the :@ modifier, by passing &pflags to
ParseModifierPart, a final $ was interpreted as an anchor, which only
makes sense in the :S and :C modifiers.

This edge case is neither used by src nor by pkgsrc, except for the unit
tests that have been adjusted.

bfa35b9119 Make DEBUG_HASH less of a fire-hose. 
Reporting keys on every lookup is overkill unless
playing with a new HASH, so wrap in #ifdef DEBUG_HASH_LOOKUP

final size and max chain length - maxchain is a better
variable name than maxlen.

60dedb5904 Fix fpu_kern_enter in a softint that interrupted a softint. 
We need to find the lwp that was originally interrupted to save its
fpu state.

With this, fpu-heavy programs (like firefox) are once again stable,
at least under modest stress testing, on systems configured to use
wifi with WPA2 and CCMP.

33ee64ee91 Save fpu state at IPL_VM to exclude fpu_kern_enter/leave. 
This way fpu_kern_enter/leave cannot interrupt the transition, so the
transition from state-on-CPU to state-in-memory (with TS set) is
atomic whether in an interrupt or not.

(I am not 100% convinced that this is necessary, but it makes
reasoning about the transition simpler.)

42b2e9dc0b Revert 1.67 "Restore the lwp's fpu state, not zeros, and leave with fpu enabled." 
This didn't actually avoid double-restore, and it doesn't solve the
problem anyway, and made it harder to detect in-kernel fpu abuse.
