I get the build failure below with AUDIT=y on ARM. The problem is
that lib/audit.c includes asm-generic/audit_dir_write.h which lists a
number of syscalls that are not defined on ARM (and some other platforms).
What's the right fix for this? I don't think I saw this problem with
2.6.18-rc7 but on the other hand I cannot see any relevant changes
since then.
The failure is:

And somebody (I forget who) was complaining that some debugging tool was only available
on the x86/sparc/ppc families of CPUs, and didn't like Alan Cox's suggestion
that they go add it.
Given that missing an entire class of syscall (the *at flavors) on an
architecture isn't a deterrent to inclusion, Alan's response was totally
on-target....
(I'm presuming the usual reason for such missing syscalls is that nobody
has bothered trying to run software that uses a *at call on an ARM, so
nobody's bothered wiring them up and thereby increasing the kernel image
size on a platform where it's likely to be *very* important?)

They probably should be wired up, but TBH I _always_ miss the addition
of such things. I don't remember there being any notification to arch
maintainers that something was due to be done.
