3f224f4e05 sh: provide generic arch_debugfs_dir. 
While sh previously had its own debugfs root, there now exists a
common arch_debugfs_dir prototype, so we switch everything over to
that.  Presumably once more architectures start making use of this
we'll be able to just kill off the stub kdebugfs wrapper.

35724a0aed sh: Fix up the cpu_asid() return value on nommu. 
This ought to be unsigned long, rather than defaulting to int.

a99d6fde69 sh: Convert sh64 /proc/asids to debugfs and generic sh. 
This converts the sh64 /proc/asids entry to debugfs and enables it for
all SH parts that have debugfs enabled.

On MMU systems this can be used to determine which processes are using
which ASIDs which in turn can be used for finer grained cache tag
analysis.
