LEROY Christophe 501c8de7b0 powerpc: add support for csum_add() ... The C version of csum_add() as defined in include/net/checksum.h gives the following assembly in ppc32: 0: 7c 04 1a 14 add r0,r4,r3 4: 7c 64 00 10 subfc r3,r4,r0 8: 7c 63 19 10 subfe r3,r3,r3 c: 7c 63 00 50 subf r3,r3,r0 and the following in ppc64: 0xc000000000001af8 <+0>: add r3,r3,r4 0xc000000000001afc <+4>: cmplw cr7,r3,r4 0xc000000000001b00 <+8>: mfcr r4 0xc000000000001b04 <+12>: rlwinm r4,r4,29,31,31 0xc000000000001b08 <+16>: add r3,r4,r3 0xc000000000001b0c <+20>: clrldi r3,r3,32 0xc000000000001b10 <+24>: blr include/net/checksum.h also offers the possibility to define an arch specific function. This patch provides a specific csum_add() inline function. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>		2015-08-07 22:59:19 -05:00
