<title>powerpc: Remove more traces of bootmem</title>

<id>e39f223fc93580c86ccf6b3422033e349f57f0dd</id>
<content type='text'>
Although we are now selecting NO_BOOTMEM, we still have some traces of
bootmem lying around. That is because even with NO_BOOTMEM there is
still a shim that converts bootmem calls into memblock calls, but
ultimately we want to remove all traces of bootmem.

Most of the patch is conversions from alloc_bootmem() to
memblock_virt_alloc(). In general a call such as:

  p = (struct foo *)alloc_bootmem(x);

Becomes:

  p = memblock_virt_alloc(x, 0);

We don't need the cast because memblock_virt_alloc() returns a void *.
The alignment value of zero tells memblock to use the default alignment,
which is SMP_CACHE_BYTES, the same value alloc_bootmem() uses.

We remove a number of NULL checks on the result of
memblock_virt_alloc(). That is because memblock_virt_alloc() will panic
if it can't allocate, in exactly the same way as alloc_bootmem(), so the
NULL checks are and always have been redundant.

The memory returned by memblock_virt_alloc() is already zeroed, so we
remove several memsets of the result of memblock_virt_alloc().

Finally we convert a few uses of __alloc_bootmem(x, y, MAX_DMA_ADDRESS)
to just plain memblock_virt_alloc(). We don't use memblock_alloc_base()
because MAX_DMA_ADDRESS is ~0ul on powerpc, so limiting the allocation
to that is pointless, 16XB ought to be enough for anyone.

<title>powerpc/pci: Support per-aperture memory offset</title>
<updated>2013-05-06T03:40:40+00:00</updated>

<id>3fd47f063b17692e843128e2abda3e697df42198</id>
<content type='text'>
The PCI core supports an offset per aperture nowadays but our arch
code still has a single offset per host bridge representing the
difference betwen CPU memory addresses and PCI MMIO addresses.

This is a problem as new machines and hypervisor versions are
coming out where the 64-bit windows will have a different offset
(basically mapped 1:1) from the 32-bit windows.

This fixes it by using separate offsets. In the long run, we probably
want to get rid of that intermediary struct pci_controller and have
those directly stored into the pci_host_bridge as they are parsed
but this will be a more invasive change.

<title>POWERPC: drivers: remove __dev* attributes.</title>

<id>cad5cef62a5a0c525d39118d2e94b6e2034d5e05</id>
<content type='text'>
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

<title>powerpc/PCI: compute I/O space bus-to-resource offset consistently</title>

Make sure we compute CPU addresses (resource start/end) the same way both
when we set up the I/O aperture (hose-&gt;io_resource) and when we use
pcibios_bus_to_resource() to convert BAR values into resources.

This fixes a build failure ("cast from pointer to integer of different
size" in configs where resource_size_t is 64 bits but pointers are 32 bits)
I introduced in 6c5705fec63d.
