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.

In commit 0fba3a1f (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.

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.

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: NLinas Vepstas <linas@austin.ibm.com>

The original code here is wrong, it applies "previous" knowledge. The way the cpufreq core is designed is that the policy for the secondary CPU that comes online says that it must in fact not use this policy but use the same as the other CPUs that are listed, which in fact is CPU#0.

Now that we always take a device tree in arch/powerpc, there's no good reason not to allow a single kernel to support multiple embedded 4xx boards - the correct platform code can be selected based on the device tree information. Therefore, this patch re-arranges the 4xx Kconfig code to allow this. In addition we: - use "select" instead of depends to configure the correct config options for specific 4xx CPUs and workarounds, which makes the information about specific boards and CPUs less scattered. - Some old, unused (in arch/powerpc) config options are removed: WANT_EARLY_SERIAL, IBM_OCP, etc. Signed-off-by: NDavid Gibson <dwg@au1.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>
