These days, the NACA only exists on iSeries. 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).

asm-ppc64/dart.h is included in exactly one place - arch/powerpc/sysdev/u3_iommu.c. This patch, therefore, moves it into arch/powerpc/sysdev. While we're at it, update the #ifndef/#define protecting the include, and the filename in the comments of u3_iommu.c. Built and booted on pSeries and G5, built for ppc32 powermac.

We were getting powerbook sleep code included, and giving compile errors, with CONFIG_PM=y on a 64-bit build. This excludes that code so the kernel will compile. One day BenH will implement on sleep on the G5... Signed-off-by: NPaul Mackerras <paulus@samba.org>

The nvram driver imported from the ppc code uses call_rtas, but rtas_call is the name we are using in merged code (since ppc64 used that name, and it uses far more RTAS calls than ppc32). Signed-off-by: NPaul Mackerras <paulus@samba.org>

Here's a revised version. 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.

We had a static memory_limit in prom.c, and then another one defined in setup_64.c and used in numa.c, which resulted in the kernel crashing when mem=xxx was given on the command line. This puts the declaration in system.h and the definition in mem.c. This also moves the definition of tce_alloc_start/end out of setup_64.c. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This fixes a bug where settimeofday would set the wrong parameters in do_gtod, resulting in gettimeofday returning a value about 4 hours after the correct time. The bug was that we divided a negative 64-bit value with do_div, which treated it as unsigned and gave us a result that was approximately 1.8e10 too large (since the divisor was 1e9).

Currently when we first select memory model (FLAT, DISCONTIG, SPARSE) then select whether the machine is NUMA. However NUMA systems may not be FLAT. This constraint it not honoured and we may configure a NUMA/FLAT system. Reorder the configuration such that we choose NUMA first which allows us to only list the memory models which are valid. We now default NUMA for known NUMA systems. Note that this new order also matches that used in x86.

Change the phys_mem_access_prot() function to take a pfn instead of an address. This allows mmap64() to work on /dev/mem for addresses above 4G on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no need to convert to an address; in fact, it's actively bad, since the conversion can overflow when the address is above 4G. Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an address by directly comparing to max_pfn. Working with max_pfn instead of high_memory fixes page_is_ram() to give the right answer for highmem pages.

The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

This patch moves the XICS interrupt controller code into the platforms/pseries directory, since it only appears on pSeries machines. If it ever appears on some other machine we can move it to sysdev, although xics.c itself will need a bunch of changes in that case to remove pSeries specific assumptions.
