* [POWERPC] powermac: Support G5 CPU hotplugJohannes Berg2007-05-073-4/+81
| | | | | | | | | | | | This allows "hotplugging" of CPUs on G5 machines. CPUs that are disabled are put into an idle loop with the decrementer frequency set to minimum. To wake them up again we kick them just like when bringing them up. To stop those CPUs from messing with any global state we stop them from entering the timer interrupt.

* [POWERPC] Add smp_call_function_map and smp_call_function_singlewill schmidt2007-05-071-21/+52
| | | | | | | | | | | | | | | Add a new function named smp_call_function_single(). This matches a generic prototype from include/linux/smp.h. Add a function smp_call_function_map(). This is, for the most part, a rename of smp_call_function, with some added cpumask support. smp_call_function and smp_call_function_single call into smp_call_function_map.

* [POWERPC] 64K page support for kexecLuke Browning2007-05-071-22/+62
| | | | | | | | | | | | | | This fixes a couple of kexec problems related to 64K page support in the kernel. kexec issues a tlbie for each pte. The parameters for the tlbie are the page size and the virtual address. Support was missing for the computation of these two parameters for 64K pages. This adds that support.

* [POWERPC] Small cleanups to the cuboot bootwrapper codeDavid Gibson2007-05-023-25/+20
| | | | | | | | | | | | | | This patch makes a few small cleanups to the cuboot code. - It removes the double layered selection of images, via cuboot-plat-y, instead having the cuboot platforms directly select a suitable image-y (this changes the name of the final cuboot image from plain cuImage to cuImage.<platform>). - Factors out some code in the wrapper that's potentially useful to platforms other than uboot.

* [POWERPC] Fix suspend states againJohannes Berg2007-05-023-65/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 0fba3a1f39f8b0a50b56c8b068fa52131cbc84c2 (a very long time ago, May 2006), I fixed a bug that caused powermacs to crash when you tried entering standby/mem suspend states. As I'm now getting more familiar with the suspend code I notice a few more things: 1. we previously misunderstood what pm_ops is for, it isn't supposed to be for doing platform dependent suspend/resume stuff that needs to be done for suspend to disk (as we currently try to use it!), it is instead for entering platform dependent suspend states ("standby", "mem"). 2. due to the first point, we never properly save FPU and altivec states when suspending to disk. It probably hasn't hurt yet because the process that writes the "disk" to /sys/power/state uses neither and its context is used. This patch addresses these points as follows: 1. remove all pm_ops from powermac, powermac suspend to ram isn't currently usable via /sys/power/state but is done via the PMU instead. 2. move the code responsible for storing FPU/altivec state into save_processor_state and the set_context() call to restore_processor_state. 3. add a call to kernel_enable_spe() It may look like there is some code removal missing but that is actually because the new suspend.h file overrides the ppc/suspend.h one which was previously used.

* [POWERPC] Fix STRICT_MM_TYPECHECKSDavid Gibson2007-05-023-3/+4
| | | | | | | | | | | | | | Since we don't have it active by default, the STRICT_MM_TYPECHECKS option has bitrotted again. This patch fixes a couple of simple build fixes if the option is selected. First, pud_t mustn't be defined in page.h on 32-bit systems, because it conflicts with the version in the generic pud-folding code. Second, pci_32.c is missing a __pgprot() wrapper call. Third, a couple of PS3 files use constants of type pgprot_t when they need the raw values, we add pgprot_val() calls to fix this.

It also substantially simplifies arch/powerpc/mm/44x_mmu.c and makes a couple of small fixes necessary for the 44x MMU code to build and work properly in arch/powerpc.

* [POWERPC] pseries: Handle null iommu dma-window property correctlyLinas Vepstas2007-05-021-0/+6
| | | | | | | | | | | | | | | | Some versions of pSeries firmware fail to set up a dma-window property for PCI slots that are unoccupied. As a result, the loop searching for this propery, in pci_dma_dev_setup_pSeriesLP(), can run to the end, resulting in a NULL pointer dereference later in the routine. This patch prevents the crash, and prints a warning message. This is theoretically a rare error, as it occurs on what is hopefully just beta levels of firmware. But just in case this firmware escapes into the wild, this patch will avoid the crash. Signed-off-by: Linas Vepstas <linas@austin.ibm.com>
