Added a new dr_mode property to describe what mode the DR controller is being used in (host, device, OTG). Updated the MPC8349E MDS dts with this new property. Signed-off-by:

H_BULK_REMOVE lets us remove 4 entries from the MMU hash table with one hypervisor call. This uses it in pSeries_lpar_hpte_invalidate so we can tear down mappings with fewer hypervisor calls. Signed-off-by:Paul Mackerras <paulus@samba.org>

Some instruction tracing tools use the RI (recoverable interrupt) bit in the MSR to indicate when it's safe to single-step. Currently we clear RI after restoring r13 when returning to userspace. However, if we single-step past the point where r13 is restored, we'll corrupt r13 in the exception entry code and not restore it. This moves the clearing of RI to just before r13 is restored so this doesn't happen. Signed-off-by: -

To the issue: some point during 2.6.20 development, Paul Mackerras introduced the "lazy IRQ disabling" patch (very cool work, BTW). In that patch, the performance monitor unit exception was marked as "maskable", in the sense that if interrupts were soft-disabled, that exception could be ignored. This broke my PowerPC profiling code. The symptom that I see is that a varying number of interrupts (from 0 to $n$, typically closer to 0) get delivered, when, in reality, it should always be very close to $n$. The issue stems from the way masking is being done. Masking in this fashion seems to work well with the decrementer and external interrupts, because they are raised again until "really" handled. For the PMU, however, this does not apply (at least on my Xserver machine with a 970FX processor). If the PMU exception is not handled, it will _not_ be re-raised (at least on my machine). The documentation states that the PMXE bit in MMCR0 is set to 0 when the PMU exception is raised. However, software must re-set the bit to re-enable PMU exceptions. If the exception is ignored (as currently) not only is that interrupt lost, but because software does not re-set PMXE, the PMU registers are "frozen" forever. [This patch means that performance monitor exceptions are taken and handled even if irqs are off, as long as some other interrupt hasn't come along and caused interrupts to be hard-disabled. In this sense the PMU exception becomes like an NMI. The oprofile code for most powerpc processors does nothing that is unsafe in an NMI context, but the Cell oprofile code does a spin_lock_irqsave. However, that turns out to be OK because Cell doesn't actually use the performance monitor exception; performance monitor interrupts come in as a regular interrupt on Cell, so will be disabled when irqs are off. -- paulus.] Signed-off-by: -

Some systems supported by the maple platform (e.g. JS2x blades running SLOF) are able to use the mmio_nvram backend for reading and writing nvram. This is an improvement over the current situation -- no nvram access from userspace at all. Select MMIO_NVRAM for the maple platform. Initialize the mmio_nvram backend from maple setup code.

The DMA controller on PWRficient is somewhat special -- has a PCI header so it looks like it's on the root PCI (-Express) root bus, but it uses more than the default number of interrupts (and they are hardwired). We need to wire up all interrupts for the DMA controller. The generic IRQ code will only map the primary interrupt from the PCI header (128), so add 129->211 by hand. Signed-off-by:

G3 Blue & White is misconfigured by default so that CardBus controllers in PCI slots don't work. The PCI bridge is programmed to only allow access to bus 1 but not higher busses. The patch forces the PCI busses to be reassigned if a Grackle controller is found and the machine identifies itself as "PowerMac1,1" Signed-off-by:

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

This contains important fixes for the CPM2 PIC code. Eliminated CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt mapping. Updated devicetree files to reflect that. Changed direct IC-related IO accesses to the IO accessors. Fixed all the sense values to keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs and hence could be hardly usable.
