2005-11-03[PATCH] ppc: Fix build warnings in arch/ppc/kernel/traps.cBecky Bruce1-4/+4
The latest updates to bug.h generate build warnings in traps.c in arch/ppc. Fix print format specifiers to account for change of line type to long from int. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-03[PATCH] ppc64: Fix add notifier crashesJohn Rose2-3/+4
The extraction of PCI stuff from struct device_node left some false assumptions in notifier code. As a result, dynamic add crashes when non-PCI nodes are added. This patch fixes these assumptions. Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-03powerpc: Merge remaining RTAS codePaul Mackerras11-161/+143
This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-02powerpc: Compile fixes for chrp/nvram.cPaul Mackerras1-2/+5

2005-11-02[PATCH] powerpc: Move naca.h to platforms/iseriesDavid Gibson5-4/+27
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).

2005-11-02[PATCH] powerpc: Move dart.hDavid Gibson2-2/+62
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.

2005-11-02powerpc: exclude powerbook sleep code with CONFIG_PPC64 and CONFIG_PMPaul Mackerras1-4/+4
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: Paul Mackerras <paulus@samba.org>

2005-11-02powerpc: Use rtas_call not call_rtas in CHRP codePaul Mackerras1-2/+4
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: Paul Mackerras <paulus@samba.org>

2005-11-01powerpc: Fix pseries (64-bit) buildPaul Mackerras1-2/+0
A recent commit that removed rtas-fw.h and moved its contents to include/asm-powerpc/rtas.h forgot to also remove the inclusion of it in arch/powerpc/platforms/pseries/setup.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-01[PATCH] powerpc: Merge bitops.hDavid Gibson6-188/+58
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.

2005-11-01[PATCH] powerpc: move mmio_nvram.c over to arch/powerpcArnd Bergmann4-1/+7
The nvram code formally known as bpa_nvram.c is rather generic really, so it is quite likely to be useful to future boards not based on cell. This patch puts it into arch/powerpc/sysdev. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-01[PATCH] powerpc: move rtas_fw.c out of platforms/pseriesArnd Bergmann5-7/+10
Cell uses the same code as pSeries for flashing the firmware through rtas, so the implementation should not be part of platforms/pseries. Put it into arch/powerpc/kernel instead. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

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: Paul Mackerras <paulus@samba.org>

2005-10-30[PATCH] fix missing includesTim Schmielau33-1/+45
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-10-30[PATCH] hpet-RTC: cache the comparator registerClemens Ladisch2-2/+8
Reads from an HPET register require a round trip to the south bridge and are almost as slow as PCI reads. By caching the last value we've written to the comparator register, we can eliminate all HPET reads from the fast path in the emulated RTC interrupt handler.

2005-10-30[PATCH] hpet-RTC: fix timer config register accessesClemens Ladisch2-14/+4
Make sure that the RTC timer is in non-periodic mode; some stupid BIOS might have initialized it to periodic mode. Furthermore, don't set the SETVAL bit in the config register. This wouldn't have any effect unless the timer was in period mode (which it isn't), and then the actual timer frequency would be half that of the desired one because incrementing the comparator in the interrupt handler would be done after the hardware has already incremented it itself.
