This re-introduces the set_bits() function from ppc64, which I removed because I thought it was unused (it exists on no other arch). In fact it is used in the powermac interrupt code (but not on pSeries). - We use LARXL/STCXL macros to generate the right (32 or 64 bit) instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S - ppc32 previously used a full "sync" barrier at the end of test_and_*_bit(), whereas ppc64 used an "isync". The merged version uses "isync", since I believe that's sufficient. - The ppc64 versions of then minix_*() bitmap functions have changed semantics. Previously on ppc64, these functions were big-endian (that is bit 0 was the LSB in the first 64-bit, big-endian word). On ppc32 (and x86, for that matter, they were little-endian. As far as I can tell, the big-endian usage was simply wrong - I guess no-one ever tried to use minixfs on ppc64. - On ppc32 find_next_bit() and find_next_zero_bit() are no longer inline (they were already out-of-line on ppc64). - For ppc64, sched_find_first_bit() has moved from mmu_context.h to the merged bitops. What it was doing in mmu_context.h in the first place, I have no idea. - The fls() function is now implemented using the cntlzw instruction on ppc64, instead of generic_fls(), as it already was on ppc32. - For ARCH=ppc, this patch requires adding arch/powerpc/lib to the arch/ppc/Makefile. This in turn requires some changes to arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc. Built and running on G5.

Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

But we've already got in the linker script, so we can just use KERNELBASE directly. That means if we ever change KERNELBASE there's one less place to change it. And we can set the entry point with ENTRY(). There are zero differences from "readelf -a vmlinux" with or without this patch.

Also gets rid of some dynamic executable cruft that we had for 32-bit. With -Ttext=$(KERNELBASE) this didn't cause any problem, but when we changed to putting . = KERNELBASE in the vmlinux.lds.S this cruft caused the text to get linked at 0xa0 instead of 0xc0000000.
