Hi all...

Long time ago noticed this, but did not remember to report till this night:
x86 seems to build altivec source files for md checksums:

  CC      drivers/md/raid6recov.o
  CC      fs/partitions/ldm.o
  CC      fs/proc/task_mmu.o
  HOSTCC  drivers/md/mktables
  CC      net/core/dev_mcast.o
  UNROLL  drivers/md/raid6int1.c
  UNROLL  drivers/md/raid6int2.c
  UNROLL  drivers/md/raid6int4.c
  UNROLL  drivers/md/raid6int8.c
  UNROLL  drivers/md/raid6int16.c
  CC      fs/proc/inode.o
  UNROLL  drivers/md/raid6int32.c
  UNROLL  drivers/md/raid6altivec1.c
  UNROLL  drivers/md/raid6altivec2.c
  UNROLL  drivers/md/raid6altivec4.c
  UNROLL  drivers/md/raid6altivec8.c
  CC      fs/partitions/msdos.o
  CC      drivers/md/raid6mmx.o
  CC      fs/proc/root.o
  CC      net/core/dst.o
  LD      fs/partitions/built-in.o
  CC      net/core/neighbour.o
  CC      drivers/md/raid6sse1.o
 =20
(buld lines are out of order due to a make -j4)

Kernel is 2.6.14-mm2.
This is an x86 box, why does it compile raid6altivec*.c ? I suppose it
does not generate any code, because of some #ifdef magic, but why does
it build them anyways ? Looks a bit strange.

Thanks.
