Vineet Gupta 64e69073c3 asm-generic headers: Allow yet more arch overrides in checksum.h 
arches can have more efficient implementation of these routines

Linas Vepstas 4e29198e1c Add extra arch overrides to asm-generic/checksum.h 
There are plausible reasons for architectures to provide their own
versions of csum_partial_copy_nocheck and csum_tcpudp_magic.
By protecting these, the architecture can still re-use the
asm-generic checksum.h, instead of copying it.

Arnd Bergmann 26a28fa4fe add generic lib/checksum.c 
Add a generic (unoptimized) implementation of checksum.c in pure C
for use by all architectures that cannot be bother with implementing
their own version.
