The unknown reason was that my PPC64 failed to compile without
it ;-) It was unknown because I forgot to mention that in the change
log (my bad).
Are you sure you were building a ppc64 kernel? This makes no sense in
that the -mno-spe flag should not be relevant at all to such a kernel
build. (No ppc64 chip has SPE support and thus the compiler doesnt
support generation of the instructions in that mode).
Were you building some ppc32 targeted kernel?
