Some IBM machines supply a "logical" PVR (processor version register) value in the device tree in the cpu nodes rather than the real PVR. This is used for instance to indicate that the processors in a POWER6 partition have been configured by the hypervisor to run in POWER5+ mode rather than POWER6 mode. To cope with this, we call identify_cpu a second time with the logical PVR value (the first call is with the real PVR value in the very early setup code). However, POWER5+ machines can also supply a logical PVR value, and use the same value (the value that indicates a v2.04 architecture compliant processor). This causes problems for code that uses the performance monitor (such as oprofile), because the PMU registers are different in POWER6 (even in POWER5+ mode) from the real POWER5+. This change works around this problem by taking out the PMU information from the cputable entries for the logical PVR values, and changing identify_cpu so that the second call to it won't overwrite the PMU information that was established by the first call (the one with the real PVR), but does update the other fields. Specifically, if the cputable entry for the logical PVR value has num_pmcs == 0, none of the PMU-related fields get used. So that we can create a mixed cputable entry, we now make cur_cpu_spec point to a single static struct cpu_spec, and copy stuff from cpu_specs[i] into it. This has the side-effect that we can now make cpu_specs[] be initdata. Ultimately it would be good to move the PMU-related fields out to a separate structure, pointed to by the cputable entries, and change identify_cpu so that it saves the PMU info pointer, copies the whole structure, and restores the PMU info pointer, rather than identify_cpu having to list all the fields that are *not* PMU-related.

Don't allow cpu hotplug on systems lacking XICS interrupt controller (i.e. with an MPIC interrupt controller), since the current pSeries platform code is hardcoded for XICS. This works around the bug reported by Paul Mackerras where the disable_nonboot_cpus() call recently added to the shutdown path will cause an oops on older pSeries machines. Signed-off-by:

Our _GLOBAL macro does a ".align 2" so the alignment is fine for 32 bit, but on 64 bit it is possible for it to end up only 4 byte aligned. I don't know if it matters, but it can't hurt to 8 byte align it. It also means that when we build with --emit_relocs, none of our 64 bit relocations are to misaligned places. Signed-off-by:

Add support for a simple tagged database in the PS3 flash rom os-area. The database allows the flash rom os-area to be shared between a bootloader and installed operating systems. The application ps3-flash-util or the library libps3-utils from the ps3-utils package can be used for userspace database operations.

Since bootdevice never gets initialized, it's always NULL, and hence a whole pile of code in arch/powerpc/platforms/setup.c never gets used. (This was the code that originally was there so that the automatic root partition selection mechanism would prefer a rootish-looking partition on the device that OF loaded the kernel from over a similar partition on other devices.) This removes the unused code. Signed-off-by:

Discussions with firmware architects have confirmed that the bit in the ibm,pa-features property that indicates support for cache-inhibited large (>= 64kB) page mappings does in fact mean that the hypervisor allows 64kB mappings to I/O devices. Thus we can now enable the code that tests that bit and sets our CPU_FTR_CI_LARGE_PAGE feature bit. Signed-off-by: -

The name field of of_platform_driver is just copied into the included device_driver. By not overriding an already initialised device_driver name, we can convert the drivers over time to stop using the of_platform_driver name. Also we were not copying the owner field from of_platform_driver, so do the same with it. Signed-off-by:

set_irq_chained_handler overwrites MPIC's handle_irq function (handle_fasteoi_irq) thus MPIC never gets eoi event from the cascaded IRQ. This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.

On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete bridges (mpc10x, tsi108) use the new for_each_compatible_node() or for_each_node_by_type() to provide more exact matching when looking for PHBs in the device tree. With the previous code it was possible to match on pci bridges since we were only matching on device_type. Signed-off-by:
