e54caebe4d Stop using _SUBDIR internally for non-SUBDIR_PARALLEL builds.
This is unifying more of the logic.  Rather than create targets such
as 'all: all_subdir_foo' when using SUBDIR_PARALLEL and using
'all: _SUBDIR' when not using SUBDIR_PARALLEL, always use the
expanded out <target>_subdir_<directory> pattern.  When not using
SUBDIR_PARALLEL, have each directory-target depend on the previously
defined targets as to respect the *order* of SUBDIR.

Using 'make -N' now prints all directory traversals individually rather
than using a loop, since a loop is no longer used to traverse.

This is part of an effort to cleanup handling of some edge cases
involving 'make <directory>' and making it simpler in the sense
that the pattern used to build is the same for all modes.

6ea8e4de48 Fix building on read-only source trees.
This partially reverts r296702 and reworks the original check to only
look in .CURDIR.  This avoids ever trying to rebuild a .src file that is
already in the source tree as an override.

8b0a83cce2 Make CloudABI work on i386.
Copy over amd64's cloudabi64_sysvec.c into i386 and tailor it to work.
Again, we use a system call convention similar to FreeBSD, except that
there is no support for indirect system calls (%eax == 0).

Where i386 differs from amd64 is that we have to store thread/process
entry arguments on the stack instead of using registers. We also have to
put an extra pointer on the stack for TLS (for GSBASE). Place that
pointer in the empty slot that is normally used to hold return
addresses. That seems to keep the code simple.

ded67349a3 Further fixes for translation of PrintScreen/SysRq.
The previous fix was tested mainly on 3 AT keyboards with USB adaptors where
it works.  1 USB keyboard doesn't translate Alt-PrintScreen, so the software
has to do it.

Reorganize a little to share some code and to not translate the unusual usb
scan code0x8a unless an Alt modified is set.  Remove redundant check of Alt
modifiers.  Translation now more clearly filters out Alt-PrintScreen before
the check.

The table of errors fixed in the previous commit had many bugs.  Correct
table:

K_RAW  Ctl-PrintScreen:                                 E0-2A-E0-37 -> E0-37
K_RAW  Alt-PrintScreen (with 4 comb. of Ctl/Shift):     79 -> 54
K_RAW  Pause/Break (with 4 comb. of Alt/Shift):         E0-46 -> E1-1D-45
K_CODE PrintScreen (with 4 comb. of Ctl/Shift):         54 -> 5c
K_CODE Alt-PrintScreen (with 4 comb. of Ctl/Shift):     7e -> 54
K_CODE Pause/Break (with 8 comb. of Ctl/Alt/Shift):     6c -> 68

That is 25 of 32 shift combinations for 2 keys fixed.  All 16 combinations
were broken for K_CODE and thus also for K_XLATE.

23424a2021 Temporarily disable the optimization from r304436
r304436 attempted to optimize the handling of incoming UDP packet by only
making an expensive call to in_broadcast() if the mbuf was marked as an
broadcast packet.  Unfortunately, this cannot work in the case of point-to-
point L2 protocols like PPP, which have no notion of "broadcast".

Discussions on how to properly fix r304436 are ongoing, but in the meantime
disable the optimization to ensure that no existing network setups are broken.

c114e74120 ioat(4): Allow callouts to be scheduled after hw reset
is_completion_pending governs whether or not a callout will be scheduled
when new work is queued on the IOAT device.  If true, a callout is
already scheduled, so we do not need a new one.  If false, we schedule
one and set it true.  Because resetting the hardware completed all
outstanding work but failed to clear is_completion_pending, no new
callout could be scheduled after a reset with pending work.

This resulted in a driver hang for polled-only work.

3f7880e23a Fix translation of the PrintScreen/SysRq and Pause/Break keys. Almost
everything was broken.  The cases that I noticed were Ctrl-PrintScreen
not being mapped to the virtual scancode 0x5c (debug) and Pause not being
mapped to the physical/virtual scancode 0x46 (slock).

These keys are the most complicated ones due to kludges to give some
compatibility back to before AT keyboards.

Alt-PrintScreen must pretend to be a separate key from PrintScreen
even at the "raw" level.  The (unique) usb code for it is 0x8a and we
just have to map this to our unique virtual scancode 0x54, but we
mapped it first to the internal code 0x7e and then to 0x79 which is a
key on the Japanese 106/109 keyboard.  This fix is under the
UKBD_EMULATE_ATASCANCODE option which shouldn't be used for non-AT
keyboards.  If it is, then the syscons Japanese keymaps have nothing
of importance for code 0x79 and can easily be changed.  0x54 is also
unimportant in Japanese and US keymaps.

NonAlt-PrintScreen and NonCtl-Pause/Break had many much larger bugs with
smaller compatibility problems from fixing them.  The details are too
ugly to give here.  Summary of the changed (hex) codes:

K_RAW  PrintScreen (Ctl, Shift, Ctl-Shift):             E0-2A-E0-37 -> E0-37
K_RAW  Alt-PrintScreen (all shift states):              79 -> 54
K_RAW  Pause/Break (unshifted, Shift, Alt, Alt-Shift)): E0-46 -> E1-1D-45
K_CODE ALT-PrintScreen (all shift states):              79 -> 54

That is 15 of 32 shift combinations for 2 keys fixed, with 8 easy cases
from the 79 -> 54 remapping.

The difference is only large and with no workaround using a keymap for
for K_RAW, but this affects other modes when ukbd is layered under kbmux
because kbmux keeps all subdevices in K_RAW mode and translates.  Oops.
I used kbdmux to generate the above table of changes.
