parisc: Provide an extru_safe() macro to extract unsigned bits The extru instruction leaves the most significant 32 bits of the target register in an undefined state on PA 2.0 systems. Provide a macro to safely use extru on 32- and 64-bit machines. Suggested-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>
