Linus Torvalds 1a3f7d98e5 Revert "UFS: add const to parser token table"
This reverts commit f9247273cb (and
fb2e405fc1 - "fix fs/nfs/nfsroot.c
compilation" - that fixed a missed conversion).

The changes cause problems for at least the sparc build.  Let's re-do
them when the exact issues are resolved.
