lib/checksum.c: make do_csum optional Mike Frysinger suggested that do_csum should be optional so that an architecture can use the generic checksum code but still provide an optimized fast-path for the most critical function. This can mean an implementation using inline assembly, or in case of Alpha one using 64-bit arithmetic in C. Cc: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
