[PATCH] added typechecking ot sparc64 ioremap()

ioremap() made inlined function on sparc64; that had caught one bogosity in
drivers, actually - cpwatchdog.c passed sizeof(structure that was never
declared) as the second argument to ioremap().  It went unnoticed since
that argument was never used in the body of macro, so it disappeared without
a trace...
