Now that the source appears to have stabilized, local changes will
happen on HEAD and will therefore cause affected files to be pulled
from the vendor branch.

all the fixes locally applied and submitted to the author. Not
included in BETA 5, but part of this import are:
o FreeBSD specific ifdefs to make this compile within a kernel.
These are limited to include directives and defines.
o Removal of unused variables, proper casts and initializations
to allow building with -Werror. This happens in code so has a
higher chance of causing future import conflicts but not enough
to worry about it.
I'm especially thankful that the author accepted the change to
replace DISABLE_TRACE with UWX_TRACE_ENABLE so that we can use it
in kernel config files without nasty mappings or indirections as
that would make the integration less perfect. Thanks Cary!

default. There were 2 cases where the trace code was in the else-
part of an if-statement without any compound construct to protect
against nullification. The result was that 2 unconditional statements
turned into conditional statements and wrecked havoc.
This fix has been returned to the vendor and in anticipation of a
future import committed onto the vendor branch.

compilation accordingly. The net effect is that tracing is not by
default present and that it can easily be compiled-in.
The tracer uses getenv() and printf(), which cannot be used in all
cases (ie from the debugger) and with this change we improved the
applicability of the unwinder.
This change is made on the vendor branch and given back to the
vendor for possible inclusion in future versions.

available by Hewlett-Packard under the MIT license. The unwinder is
small, clean and fast and needed little adaptation for use in the
kernel.
This import has embedded in it the changes needed to make it build
in a kernel environment.
To optimize the common case, the kernel will minimize the number
of registers saved by not saving the preserved registers. In case
access to preserved registers is needed (signal handling, ptrace)
the kernel will unwind to the context of the syscall or exception.
For this we need an unwinder.
