Hi Joseph, This is an awesome effort, and greatly appreciated. However in it's current form it's not easily mergeable, because it touches five architectures and has the potential to cause breakage on all of them. It's also too late for 4.2. The merge window for 4.2 is open now, which means arch maintainers have stopped taking intrusive patches 1-2 weeks ago. Is there some way you can imagine of splitting this up into smaller chunks, so that different arches can merge the pieces separately? cheers arch/alpha/include/asm/sfp-machine.h | 3 arch/alpha/math-emu/math.c | 131 - arch/powerpc/include/asm/sfp-machine.h | 39 arch/powerpc/math-emu/fadd.c | 6 arch/powerpc/math-emu/fadds.c | 6 arch/powerpc/math-emu/fcmpo.c | 2 arch/powerpc/math-emu/fcmpu.c | 2 arch/powerpc/math-emu/fctiw.c | 2 arch/powerpc/math-emu/fctiwz.c | 2 arch/powerpc/math-emu/fmadd.c | 8 arch/powerpc/math-emu/fmadds.c | 8 arch/powerpc/math-emu/fmsub.c | 8 arch/powerpc/math-emu/fmsubs.c | 8 arch/powerpc/math-emu/fnmadd.c | 8 arch/powerpc/math-emu/fnmadds.c | 8 arch/powerpc/math-emu/fnmsub.c | 8 arch/powerpc/math-emu/fnmsubs.c | 8 arch/powerpc/math-emu/fsub.c | 6 arch/powerpc/math-emu/fsubs.c | 6 arch/powerpc/math-emu/lfs.c | 11 arch/powerpc/math-emu/math_efp.c | 254 +- arch/powerpc/math-emu/stfs.c | 6 arch/s390/include/asm/sfp-machine.h | 10 arch/s390/kernel/sysinfo.c | 11 arch/sh/include/asm/sfp-machine.h | 10 arch/sh/math-emu/math.c | 51 arch/sparc/include/asm/sfp-machine_32.h | 3 arch/sparc/include/asm/sfp-machine_64.h | 3 arch/sparc/math-emu/math_32.c | 144 - arch/sparc/math-emu/math_64.c | 140 - include/math-emu/double.h | 398 ++-- include/math-emu/op-1.h | 554 +++--- include/math-emu/op-2.h | 1136 ++++++------ include/math-emu/op-4.h | 1457 ++++++++------- include/math-emu/op-8.h | 211 +- include/math-emu/op-common.h | 2927 ++++++++++++++++++++++---------- include/math-emu/quad.h | 434 +++- include/math-emu/single.h | 233 +- include/math-emu/soft-fp.h | 367 ++-- 39 files changed, 5433 insertions(+), 3196 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
