By the way, I think it would be nice if the memory size detection (or,
rather retrieval of the size) could be moved to one of the
ARM-architecture-dependent files.
While I'm at it, is it true that current->tss.memmap should always be
equal to __virt_to_phys((unsigned long) &swapper_pg_dir) ? If yes, it
would be nice if this could be set in the general ARM code. Right now,
7110 and RPC set current->tss.memmap at run time, while all other
architectures use the compile-time default.
I've appended the patch I currently have in my 7110 tree for the latter
change. (Note: it doesn't touch the RPC code or the compile-time
default.)
