This re-introduces the set_bits() function\nfrom ppc64, which I removed because I thought it was unused (it exists\non no other arch). In fact it is used in the powermac interrupt code\n(but not on pSeries).\n\n- We use LARXL/STCXL macros to generate the right (32 or 64 bit)\n instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S\n\n- ppc32 previously used a full \"sync\" barrier at the end of\n test_and_*_bit(), whereas ppc64 used an \"isync\". The merged version\n uses \"isync\", since I believe that\u0027s sufficient.\n\n- The ppc64 versions of then minix_*() bitmap functions have changed\n semantics. Previously on ppc64, these functions were big-endian\n (that is bit 0 was the LSB in the first 64-bit, big-endian word).\n On ppc32 (and x86, for that matter, they were little-endian. As far\n as I can tell, the big-endian usage was simply wrong - I guess\n no-one ever tried to use minixfs on ppc64.\n\n- On ppc32 find_next_bit() and find_next_zero_bit() are no longer\n inline (they were already out-of-line on ppc64).\n\n- For ppc64, sched_find_first_bit() has moved from mmu_context.h to\n the merged bitops. What it was doing in mmu_context.h in the first\n place, I have no idea.\n\n- The fls() function is now implemented using the cntlzw instruction\n on ppc64, instead of generic_fls(), as it already was on ppc32.\n\n- For ARCH\u003dppc, this patch requires adding arch/powerpc/lib to the\n arch/ppc/Makefile.
