I guess this may be the only patch needed so far. x86_64 doesn't use a RWSEM_XCHGADD_ALGORITHM, and as for the other archs: alpha and ia64 - doesn't have PREEPMT_RT yet. arm, cris, frv, h8300, m32r, parsic don't seem to implement the XCHGADD. But I see that powerpc will need a fix, but I'll let others who actually have the boards to fix them. ;-) As for what I own: x86_64 and i386, the patches I sent are sufficient. If anyone would like to give me a special board (to keep), I'll gladly make sure that Ingo's -RT kernel runs on it. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
