variables. These are intended to allow bypassing the
'svn co /usr/{src,doc,ports}' step in the chroot when the
tree exists from external means.
The use case here is that /usr/src, /usr/doc, and /usr/ports
in the chroot exist as result of zfs dataset clones, so it
is possible (and happens quite often) that the included
distributions may not be consistent. (This is not the case
for -RELEASE builds, but does happen for snapshot builds.)

This code was heavily broken few months ago during CAM locking changes.
Fixing it would require almost complete rewrite. Since there are no
known devices on market using this interface younger then ~15 years, and
they are CD, not even DVD, I don't see much reason to rewrite it.
This change does not mean those devices won't work. They will just work
slower due to inefficient disks load/unload schedule if several LUNs
accessed same time.

other modes supported by the FTDI serial adapter chips.
In addition to adding the new ioctls, this change removes all the code
that reset the chip at attach and open/close time, and also the code
that turned on RTS/CTS flow control on open without any permission to do
so (that was just always a bug in the driver).
When FTDI chips are configured as GPIO or MPSSE or other special-purpose
uses by an attached serial eeprom, the chip will power on with certain
pins driven or floating, and it's important that the driver not do
anything to the chip to perturb that unless it receives a specific
command to do so. When used for "plain old serial comms" the chip
powers on into the right mode and never needs to be reset while it's
running to operate properly, so this change is transparent to most users.

When set to a non-empty value, the installation medium is
compressed with gzip(1) as part of the 'install' target in
the release/ directory.
With gzip(1) compression, downloadable image are reduced in
size quite significantly. Build test against head@263927
shows the following:
bootonly.iso: 64% smaller
disc1.iso: 44% smaller
memstick.img: 47% smaller
mini-memstick.img: 65% smaller
dvd1.iso: untested
This option is off by default, I would eventually like to
turn it on by default, and remove the '-k' flag to gzip(1)
so only compressed images are published on FTP.

being defined. The system works fine without it (because GNUCXX isn't
built when WITHOUT_CXX is defined), and it is one of the few places we
test WITHOUT_FOO instead of MK_FOO in the base system. Simply
eliminate it to solve both problems. Also, minor tweak to make it
clearer that the default is always NO for GNUGCC on i386.
introduced, the meaning of WITH_FDT changed from 'do FDT in boot
loader and build dtc compiler' to be simply 'do FDT things in the boot
loader'. Now that we test for FDT in the architecture specific files,
this test here is now redunant and encourages bad behavior, so just
eliminate it and make it always yes. Those architectures whose boot
loaders don't support FDT already omit it when it is set to yes
anyway.
guess wrong for buildkernel when CC=gcc49, say. Eliminate all the
guessing. COMPILER_TYPE propigates properly on its own, if specified,
and we guess it correctly otherwise lower in the build. Also, fix
conditionals for armv6hf when using an external compiler chain. They
were broken before, but unused. Also, prefer checking the compiler
type over CLANG_IS_CC since the latter is only supposed to be used to
determine what symlinks to install (more fixes to follow).
when both WITH_FOO and WITHOUT_FOO are set. Use this where
possible. Only disallow setting of MK_FOO on the command line. This
was preferable to inventing a new mechanism or fixing the undef bug
(bin/183762) which precludes users from turning off anything we turn
off for parts of the build with WITHOUT_FOO prior to this.
all the SUBDIR entries in parallel, instead of serially. Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with
buildworld!

This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.
armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
* WITH_ARM_EABI
* WITHOUT_GCC
* WITHOUT_GNUCXX
In addition, without an external toolchain, the following need to be left
as their default:
* WITH_CLANG
* WITH_CLANG_IS_CC
As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.
To reduce the diff struct pcu.cnt field was not renamed, so
PCPU_OP(cnt.field) is still used. pc_cnt and pcpu are also used in

Bump __FreeBSD_version_ in case some out-of-tree module/code relies on the

As a prerequisite for multiple queues, the guest must have MSIX enabled.
Unfortunately, to work around device passthrough bugs, FreeBSD disables
MSIX when running as a VMWare guest due to the hw.pci.honor_msi_blacklist
