Hi Everyone,

Thanks for the feedback to folks who sent them in.

Here's some further patches. I've broken them out for your convenience:

i) atf(7) tests for the new consolidated "API". These are with the
caveat that they will change along with the implementation code, when
the actual unplug API hits the road. Santhosh (Cc:ed) collaborated
closely with me for these.

ftp://ftp.netbsd.org/pub/NetBSD/misc/cherry/uvm_physmem/cvs.tests.sys.uvm.diff

ii) uvm(9) changes. The #ifdef _KERNEL_OPT is required for the rump(9)
testing code (see (ii) below:

ftp://ftp.netbsd.org/pub/NetBSD/misc/cherry/uvm_physmem/cvs.sys.uvm.diff

iii) port specific changes. I have only tested i386 and amd64. I have
compiled all ports in these diffs.

*Portmasters*, it would be immensely helpfull if you could test them on
your respective ports please.

ftp://ftp.netbsd.org/pub/NetBSD/misc/cherry/uvm_physmem/cvs.sys.arch.diff

Please, no KNF comments yet - I will clean up in a final pass - I'm
really looking for testing and reporting on function (or breakage!)

I will aim to cut a branch in CVS RSN.

Many Thanks,
