Initialise the ppc_md htab callbacks earlier, in the probe routines. This allows us to call htab_finish_init() from htab_initialize(), and makes it private to hash_utils_64.c. Move htab_finish_init() and make_bl() above htab_initialize() to avoid forward declarations. Signed-off-by:

To support muti-platform binaries the spu hypervisor accessor routines must have runtime binding. I removed the existing statically linked routines in spu.h and spu_priv1_mmio.c and created new accessor routines in spu_priv1.h that operate indirectly through an ops struct spu_priv1_ops. spu_priv1_mmio.c contains the instance of the accessor routines for running on raw hardware.

This is a first version of support for the Cell BE "Reliability, Availability and Serviceability" features. It doesn't yet handle some of the RAS interrupts (the ones described in iic_is/iic_irr), I'm still working on a proper way to expose these. They are essentially a cascaded controller by themselves (sic !) though I may just handle them locally to the iic driver. I need also to sync with David Erb on the way he hooked in the performance monitor interrupt. So that's all for 2.6.17 and I'll do more work on that with my rework of the powerpc interrupt layer that I'm hacking on at the moment. Signed-off-by:

The IBM Cell blade firmware might confuse the kernel to think it's a pSeries machine. This fixes it for now. With a bit of luck, the firmware will be updated to avoid that in the future but currently that patch is needed. Signed-off-by:

Based on an older patch from Mike Kravetz <kravetz@us.ibm.com> We need to have a mem_map for high addresses in order to make fops->no_page work on spufs mem and register files. So far, we have used the memory_present() function during early bootup, but that did not work when CONFIG_NUMA was enabled. We now use the __add_pages() function to add the mem_map when loading the spufs module, which is a lot nicer. Signed-off-by:

This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine. Signed-off-by:

set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted(). This allows more debug checking, and tighter control on how code is allowed to play around with page->_count. Signed-off-by:

Implementing the machine_crash_shutdown which will be called by crash_kexec (called in case of a panic, sysrq etc.). Disable the interrupts, shootdown cpus using debugger IPI and collect regs for all CPUs. elfcorehdr= specifies the location of elf core header stored by the crashed kernel. This command line option will be passed by the kexec-tools to capture kernel. savemaxmem= specifies the actual memory size that the first kernel has and this value will be used for dumping in the capture kernel.

This adds a scheduler for SPUs to make it possible to use more logical SPUs than physical ones are present in the system. Currently, there is no support for preempting a running SPU thread, they have to leave the SPU by either triggering an event on the SPU that causes it to return to the owning thread or by sending a signal to it. This patch also adds operations that enable accessing an SPU in either runnable or saved state. We use an RW semaphore to protect the state of the SPU from changing underneath us, while we are holding it readable. In order to change the state, it is acquired writeable and a context save or restore is executed before downgrading the semaphore to read-only.

This patch merges, to some extent, the PPC32 and PPC64 kexec implementations. We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions. The current PPC64 implementation becomes the "default" implementation for PPC64 which platforms can select if they need no special treatment. I've added these default callbacks to pseries/maple/cell/powermac, this means iSeries no longer supports kexec - but it never worked anyway. I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with PPC64. Judging by the comments it might be better named machine_kexec_non_of, or something, but at the moment it's the only implementation for PPC32 so it's the "default". Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we already have in setup-common.c on powerpc. All this does is call ppc_md.nvram_sync, which only powermac implements, so instead make machine_shutdown a ppc_md member and have it call core99_nvram_sync directly on powermac. I've also stuck relocate_kernel.S into misc_32.S for powerpc. Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on P5 LPAR and successfully kexec'ed. Should apply on top of 493f25ef. Signed-off-by:

Implementation of software load support for the BE iommu. This is very different from other iommu code on ppc64, since we only do a static mapping. The mapping is currently hardcoded but should really be read from the firmware, but they don't set up the device nodes yet. There is a single 512MB DMA window for PCI, USB and ethernet at 0x20000000 for our RAM. The Cell processor can put the I/O page table either in memory like the hashed page table (hardware load) or have the operating system write the entries into memory mapped CPU registers (software load). I use the software load mechanism because I know that all I/O page table entries for the amount of installed physical memory fit into the IO TLB cache. At the point when we get machines with more than 4GB of installed memory, we can either use hardware I/O page table access like the other platforms do or dynamically update the I/O TLB entries when a page fault occurs in the I/O subsystem. The software load can then use the macros that I have implemented for the static mapping in order to do the TLB cache updates. Signed-off-by:

Add support for the integrated interrupt controller on BPA CPUs. There is one of those for each SMT thread. The mapping of interrupt numbers to HW interrupt sources is described in arch/ppc64/kernel/bpa_iic.h. This version hardcodes the 'Spider' chip as the secondary interrupt controller. That is not really generic for the architecture, but at the moment it is the only secondary PIC that exists. A little more work will be needed on this as soon as we have boards with multiple external interrupt controllers. Signed-off-by:
