edac/85xx: Add PCIe error interrupt edac support

Add pcie error interrupt edac support for mpc85xx, p3041, p4080, and
p5020. The mpc85xx uses the legacy interrupt report mechanism - the
error interrupts are reported directly to mpic. While the p3041/
p4080/p5020 attaches the most of error interrupts to interrupt zero. And
report error interrupts to mpic via interrupt 0.

This patch can handle both of them.

metag: dma: remove dead code in dma_alloc_init()

Meta has 2 levels of page table so the pmd folds into the pud which
folds into the pgd. Therefore the !pmd check in dma_alloc_init() is dead
code since it essentially checks whether:
  (init_mm->pgd + 0x770) == 0

Remove the check.

m68k/sun3: Dynamically allocate the table to track IOMMU use

As Sun 3 kernels cannot be multi-platform due to the different Sun 3 MMU
type, it made sense to statically allocate the table to track IOMMU use.

However, Sun 3x kernels can be multi-platform. Furthermore, Sun 3x uses
a larger table than Sun 3 (8192 bytes instead of 512 bytes).

Hence switch to dynamic allocation of this table using the bootmem
allocator to avoid wasting 8192 bytes when not running on a Sun 3x.
As this allocator returns zeroed memory, there's no need to explicitly
initialize the table to zeroes.

zorro: Do not allocate zorro_autocon[] statically

Currently the array of Zorro devices is allocated statically, wasting
up to 4.5 KiB when running an Amiga or multi-platform kernel on a machine
with no or a handful of Zorro expansion cards. Convert it to conditional
dynamic memory allocation to fix this.

amiga_parse_bootinfo() still needs to store some information about the
detected Zorro devices, at a time even the bootmem allocator is not yet
available.  This is now handled using a much smaller array (typically less
than 0.5 KiB), which is __initdata and thus freed later.

zorro: Don't fill in dummy names in zorro_name_device()

If the device is not found in the database, it's not needed to fill in
a dummy name. The caller of zorro_name_device() has already taken care
of that to support CONFIG_ZORRO_NAMES=n.

zorro: Let the driver core handle device enumeration

Filling in dev_name of the Zorro bus type and dev.id of each device allows
the driver core to enumerate devices, so we don't have to do that
ourselves.

This changes the names of devices in sysfs from "%02x" to "zorro%u".

Note that filling in dev.id is also needed to support MFD Zorro devices.

zorro: ZTWO_VADDR() should return "void __iomem *"

ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should
return "void __iomem *" instead of "unsigned long".

This allows to drop several casts, but requires adding a few casts to
accomodate legacy driver frameworks that store "unsigned long" I/O
addresses.

zorro/UAPI: Disintegrate include/linux/zorro*.h

The Zorro definitions and device IDs are used by bootstraps, hence they
should be exported through UAPI.

Unfortunately zorro.h was never marked for export when headers_install
was introduced, so it was forgotten during the big UAPI disintegration.
In addition, the removal of zorro_ids.h had been sneaked into commit
7e7a43c32a8970ea2bfc3d1af353dcb1a9237769 ("PCI: don't export device IDs to
userspace") before, so it was also forgotten.

Split off and export the Zorro definitions used by bootstraps.
