Hi,

As discussed at [1] the __nocache_fix() macro in sparc's SRMMU can be made
type safe and so the compiler will yell anout misuse of pXd pointers for
which the __nocache_fix() is primarily used.

The first patch is an fix of such misuse that I've discovered after adding
type cast to __nocache_fix(), but to avoid breaking bisection I've made it
the first commit.

v2: rebased on v5.8-rc2+

Sincerely yours,
Mike.
