2011-03-30powerpc/pseries/smp: query-cpu-stopped-state support won't changeMilton Miller
If a given firmware doesn't have a token to support query-cpu-stopped-state, its not likely to change during the lifetime of the kernel. Only print this information once, not once per secondary thread. While here, make the line wrap grep friendly.

2011-03-30powerpc/xics: Use hwirq for xics domain irq numberMilton Miller

2011-03-30powerpc/xics: Fix numberspace mismatch from irq_desc conversionMilton Miller
commit 79f26c268ebad29bd75d078cfc09d3d82b30ccbd (powerpc: platforms/pseries irq_data conversion) pushed irq_desc down into many functions, dererencing the descriptor irq field as late as possible. But it incorrectly passed a linix virtural irq number to RTAS, resulting in the interrupt not being disabled and possibly other bad things, such as another interrupt being disabled and/or a checkstop. In addition this missed the point of xics_mask_unknown_vec and the seperation of xics_mask_real_irq from xics_mask_irq. When xics_mask_unknown_vec is called it's because the hardware delivered an irq source for which we have no linux irq allocated, and thefore we can not have an irq_desc allocated. Revert xics_mask_real_irq to its prior version, naming the argument hwirq to highlight the difference.

2011-03-29powerpc: cell: Fix the irq_desc accessThomas Gleixner
The core irq_set_type() function updates the flow type when the chip callback returns 0. It also updates irq_data, so this can be used in irq_ack() to check for the level bit. That avoids a redundant sparse irq lookup. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

If the spin table is located in the linear mapping (which can happen if we have 4G or more of memory) we need to access the spin table via a cacheable coherent mapping like we do on ppc32 (and do explicit cache flush).

2011-03-11powerpc/pseries: Disable MSI using new interface if possibleNishanth Aravamudan
On upcoming hardware, we have a PCI adapter with two functions, one of which uses MSI and the other uses MSI-X. This adapter, when MSI is disabled using the "old" firmware interface (RTAS_CHANGE_FN), still signals an MSI-X interrupt and triggers an EEH. We are working with the vendor to ensure that the hardware is not at fault, but if we use the "new" interface (RTAS_CHANGE_MSI_FN) to disable MSI, we also automatically disable MSI-X and the adapter does not appear to signal any stray MSI-X interrupt.

2011-03-10powerpc/iseries: Fix early init access to lppacaBenjamin Herrenschmidt
The combination of commit 8154c5d22d91cd16bd9985b0638c8957e4688d0e and 93c22703efa72c7527dbd586d1951c1f4a85fd70 Broke boot on iSeries. The problem is that iSeries very early boot code, which generates the device-tree and runs before our normal early initializations does need access the lppaca's very early, before the PACA array is initialized, and in fact even before the boot PACA has been initialized (it contains all 0's at this stage). However, the first patch above makes that code use the new llpaca_of(cpu) accessor, which itself is changed by the second patch to use the PACA array. We fix that by reverting iSeries to directly dereferencing the array. In addition, we fix all iterators in the iSeries code to always skip CPU whose number is above 63 which is the maximum size of that array and the maximum number of supported CPUs on these machines. Additionally, we make sure the boot_paca is properly initialized in our early startup code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Currently, ppc32 uses sysdata for the pci_controller pointer, and ppc64 uses it to hold the device_node pointer.
