This patch allowed my sparc cross compiler to build beyond mm/memcontrol.o, but
I faced a build issue at
drivers/net/e1000e/netdev.c: In function 'e1000e_update_stats':
drivers/net/e1000e/netdev.c:2583: error: unable to find a register to spill in
class 'FP_REGS'
drivers/net/e1000e/netdev.c:2583: error: this is the insn:

drivers/net/e1000e/netdev.c:2583: confused by earlier errors, bailing out
make[3]: *** [drivers/net/e1000e/netdev.o] Error 1
make[2]: *** [drivers/net/e1000e] Error 2
make[1]: *** [drivers/net] Error 2
So for the problem reported
