the parentheses around the location for simple fail points into the
location string. This makes the print on fail point set more
consistent between the two versions.
Also fix up fail.h a little for style(9): only use one of sys/param.h
and sys/types.h, and use the existing __XSTRING() macro instead of
rolling our own. Also fix up a few tabs on changed and nearby lines.
Lastly, since KFAIL_POINT_{BEGIN,END} are not meant for use outside
this file, just eliminate the macros entirely.

and in many respects can be thought of as a more generic superset of pfil.
Hhook provides a way for kernel subsystems to export hook points that Khelp
modules can hook to provide enhanced or new functionality to the kernel. The
KPI has been designed to ensure hook points pose no noticeable overhead when
no hook functions are registered.
- Introduce the Khelp (Kernel Helpers) KPI. Khelp provides a framework for
managing Khelp modules, which indirectly use the Hhook KPI to register their
hook functions with hook points of interest within the kernel. Khelp modules
aim to provide a structured way to dynamically extend the kernel at runtime in
an ABI preserving manner. Depending on the subsystem providing hook points, a
Khelp module may be able to associate per-object data for maintaining relevant
state between hook calls.
- pjd's Object Specific Data (OSD) KPI is used to manage the per-object data
allocated to Khelp modules. Create a new "OSD_KHELP" OSD type for use by the
Khelp framework.
- Bump __FreeBSD_version to 900028 to mark the introduction of the new KPIs.

The #define for warnx now behaves much like the libc function (except that
it uses sh command name and output).
Also, it now uses C99 __VA_ARGS__ so there is no need for three different
macros for 0, 1 or 2 parameters.

the requested read or write could fail because the targeted page could be
reclaimed between the calls to vm_fault() and vm_page_hold().

This is done to speed up extraction significantly (both for portsnap
extract and update) in the case of slow NSS modules (like nss_ldap) as
it avoids having to look up uid and gid for root / wheel.
The reason this is a bigger problem for portsnap than for many other
system operations, is that portsnap executes tar(1) once for each port
so the internal uid/gid caching in tar(1) only helps a bit, resulting
in many user lookup calls.
