relative to .CURDIR if not already defined. This makes the makefiles
more readable but also more re-usable and adaptable.

waiting sync pass we need to do a blocking acquire and restart.
Another thread, typically the buf daemon, may have this buf locked and
if we don't wait we can fail to sync the file. This lead to a great
variety of softdep panics because we rely on all dependencies being
flushed before proceeding in several cases.

This could cause dirhash panics since the dirhash state would be
successfully truncated while the directory was not.

After several months of testing and fixing (and breaking)
various parts of release/release.sh changes, it is now
possible to build FreeBSD/arm images as part of the release
process.
When EMBEDDEDBUILD is set in the release.conf file, release.sh
will create the build environment, then run a separate script
in release/${XDEV}/release.sh [1]. Currently, only arm is
supported.
The release/${XDEV}/release.sh configures the build environment
specific for the target image, such as installing gcc(1),
installing additional third-party software from the ports tree,
and fetching external sources.
Once the build environment is set up, release/${XDEV}/release.sh
runs Crochet, written by Tim Kientzle, which builds the userland
and kernel, and creates an image that can be written to an SD
card with dd(1). Many thanks to Tim for his work on Crochet.
Sample configurations for FreeBSD/arm boards are in the
release/arm/ directory, and Crochet configuration files for each
board are located in release/tools/arm/. Supported boards at this
time are: BEAGLEBONE, PANDABOARD, RPI-B, and WANDBOARD-QUAD.
Adding support for additional boards will continue in the
projects/release-embedded/ branch, and incrementally merged back
to head/.
Many thanks to the FreeBSD Foundation for the support and
sponsorship of this project.
[1] XDEV is used in order to keep the various configurations
organized by architecture, but since TARGET and TARGET_ARCH
are used to build the chroot, the values of those variables
cannot be used.

Don't produce an alias between destructors with different calling conventions.
Fixes pr19007.
(Please note that is an LLVM PR identifier, not a FreeBSD one.)
This should fix Firefox and/or libxul crashes (due to problems with
regparm/stdcall calling conventions) on i386.

after r262763 it started to return locked mutexes to UMA. To fix that,
conditionally unlock the mutex in the destructor.

This fixes kernel panic during boot, caused by incompatibility of recent
CAM locking changes and this bus scanner code.

There are a number of reports of userspace application crashes that
are "solved" by setting vm.pmap.pcid_enabled=0, including Java and the
x11/mate-terminal port (PR ports/184362).
I originally planned to disable this only in stable/10 (in r262753), but
it has been pointed out that additional crash reports on HEAD are not
likely to provide new insight into the problem. The feature can easily
be enabled for testing.

This is from commit hash '6a8a2364434763a033781f6b2a605ace9a021013'.
This makes it possible to use CRC64 but for now it's intentionally
not added to build.
- Use counter(9) for rt_pksent (former rt_rmx.rmx_pksent). This
removes another cache trashing ++ from packet forwarding path.
- Create zini/fini methods for the rtentry UMA zone. Via initialize
mutex and counter in them.
- Fix reporting of rmx_pksent to routing socket.
- Fix netstat(1) to report "Use" both in kvm(3) and sysctl(3) mode.
The change is mostly targeted for stable/10 merge. For head,
rt_pksent is expected to just disappear.
