* [PATCH] Remove SPAN_OTHER_NODES config definitionMike Kravetz2005-11-181-13/+0
| | | | | | | | | | | | | The config option SPAN_OTHER_NODES was created so that we could make pSeries numa layouts work within the DISCONTIG memory model. Now that DISCONTIG has been replaced by SPARSEMEM, we can eliminate this option. I'll be sending a separate patch to Andrew to remove the arch independent code as pSeries was the only arch that needed this.

* powerpc: Mark PREP and embedded as broken for nowPaul Mackerras2005-11-141-2/+2

* [PATCH] ppc64: Convert NUMA to sparsemem (3)Anton Blanchard2005-11-111-8/+3
| | | | | | | | | | | | | | | | Convert to sparsemem and remove all the discontigmem code in the process. This has a few advantages: - The old numa_memory_lookup_table can go away - All the arch specific discontigmem magic can go away We also remove the triple pass of memory properties and instead create a list of per node extents that we iterate through. A final cleanup would be to change our lmb code to store extents per node, then we can reuse that information in the numa code.

This seems to be done in other parts of the Kconfig file. Using those as an example, this should keep the MAX_ORDER block size at 16MB.

* [PATCH] Move Kprobes and Oprofile to "Instrumentation Support" menuPrasanna S Panchamukhi2005-11-071-0/+13
| | | | | | | | | | | | | | | Andrew Morton suggested to move kprobes from kernel hacking menu, since kernel hacking menu is in-appropriate for the Kprobes. This patch moves Kprobes and Oprofile under instrumentation menu. (akpm: it's not a natural fit, but things like djprobes and the s390 guys' statistics library need a home) Signed-of-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Cc: Philippe Elie <phil.el@wanadoo.fr> Cc: John Levon <levon@movementarian.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] ppc64: support 64k pagesBenjamin Herrenschmidt2005-11-071-0/+9
| | | | | | | | | | | | | | | Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

| | | | | | | | | 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.

* [PATCH] powerpc: move mmio_nvram.c over to arch/powerpcArnd Bergmann2005-11-011-0/+5
| | | | | | | | | | | 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.

* [PATCH] ppc64 memory model depends on NUMAAndy Whitcroft2005-10-291-8/+5
| | | | | | | | | | | | | | | 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.

* powerpc: Merge 32-bit CHRP support.Paul Mackerras2005-10-261-1/+1

* powerpc: Pull out MPC106 (grackle) initialization code into its own filePaul Mackerras2005-10-261-0/+5
| | | | | | | | This is so that the 32-bit CHRP code can use it. The MPC106 initialization code is now in arch/powerpc/sysdev/grackle.c and is controlled by CONFIG_PPC_MPC106. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Merge rtas.c into arch/powerpc/kernelPaul Mackerras2005-10-261-0/+13
| | | | | | | | | | | | | This splits arch/ppc64/kernel/rtas.c into arch/powerpc/kernel/rtas.c, which contains generic RTAS functions useful on any CHRP platform, and arch/powerpc/platforms/pseries/rtas-fw.[ch], which contain some pSeries-specific firmware flashing bits. The parts of rtas.c that are to do with pSeries-specific error logging are protected by a new CONFIG_RTAS_ERROR_LOGGING symbol. The inclusion of rtas.o is controlled by the CONFIG_PPC_RTAS symbol, and the relevant platforms select that. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Merge i8259.c into arch/powerpc/sysdevPaul Mackerras2005-10-261-0/+10
| | | | | | | | | | | | This changes the parameters for i8259_init so that it takes two parameters: a physical address for generating an interrupt acknowledge cycle, and an interrupt number offset. i8259_init now sets the irq_desc[] for its interrupts; all the callers were doing this, and that code is gone now. This also defines a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and makes the platforms that need it select that symbol. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc: Use the indirect_pci.c from arch/powerpc/sysdevPaul Mackerras2005-10-261-0/+10
| | | | | | | | This defines a CONFIG_INDIRECT_PCI symbol to control whether it gets used or not, and fixes the Kconfig to select that symbol for platforms that need it. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Merge in 64-bit powermac support.Paul Mackerras2005-10-221-0/+1
| | | | | | | | | | This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to arch/powerpc/platforms/powermac/*.c and makes various minor tweaks elsewhere. On the powermac we now initialize ppc_md by copying the whole pmac_md structure into it, which required some changes in the ordering of initializations of individual fields of it.

* powerpc: make iSeries boot againStephen Rothwell2005-10-121-1/+1
| | | | | | | | | | | | | | | | On ARCH=ppc64 we were getting htab_hash_mask recalculated to the correct value for our particular machine by accident. In the merge tree, that code was commented out, so htab_hash_mask was being corrupted. We now set ppc64_pft_size instead which gets htab_has_mask calculated correctly for us later. We should put an ibm,pft-size property in the device tree at some point. Also set -mno-minimal-toc in some makefiles. Allow iSeries to configure PROC_DEVICETREE.

| | | | | | | | These days there is no good reason to run a ppc32 kernel on a 64-bit cpu, rather than a ppc64 kernel, so remove the config option and a bunch of code (and ifdefs) from head.S. Signed-off-by: Paul Mackerras <paulus@samba.org>

Merge ppc64 traps.c into powerpc traps.c: use ppc64 versions of exception routine names (as they don't have StudlyCaps) make all the versions if die() have the same prototype Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras2005-09-261-0/+861
This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.
