Subject: [PATCH mips-next 0/3] MIPS: fix the two most annoying sparse floods

This set addresses the two most annoying sparse floods when building the
tree with C={1,2}: one in asm/io.h (in several mangle-port.h actually),
and one in asm/checksum.h.
Both of these comes from lack of forced typecasting and hence harmless,
but complicates real bug hunting, as asm/io.h is included in almost
every driver, while asm/checksum.h is included in lots of networking
code.

I also fixed two wrong __mem_ioswabq() macros while was nearby.
Tested on Generic MIPS platform -- no more flooding in console (there's
one more source in mips-cm.h, but it's included in just a few files, so
not a real problem. It can be issued separately anyway), while objdump
doesn't see any difference at all.

Alexander Lobakin (3):
  MIPS: generic/ip32: io: fix __mem_ioswabq()
  MIPS: io: fix sparse flood on asm/io.h
  MIPS: checksum: fix sparse flooding on asm/checksum.h
