[parisc-linux] Nonexistance of asm/offsets.h

[Jeff Bailey]

In the process of getting the world up, running and debugged with
NPTL, Randolph has provided a patch to make gdb work better.  Building
this on Ubuntu turned out to be a problem because we're using the
exported kernel headers rather than the mashup that Debian has been
using.

The challenge is that the Debian kernel packages used to generate
asm/offsets.h from the 64-bit kernel build's asm-offsets.h and make
that available.  When we created linux-kernel-headers, we just
imported that.

Now, with the sanitised kernel headers being produced from the kernel
source, this no longer seems right.  It means that there's a header
that's not right for both 32-bit and 64-bit userspace, and it's being
generated, so it might change by accident and break the userspace ABI.
 I'd like to propose that we create a hand-crafted offsets.h that is
intended for userspace consuption and then stop generating the
asm-offsets.h file at build time.  I'll put together a patch to do
this over the weekend unless there's objections.
