The apm module were renamed to apm_32 during the merge of 32 and 64 bit

x86: fix ioremap RAM check
this check was too strict and caused an ioremap() failure.
the problem is due to the somewhat unclean way of how the GART code
reserves a memory range for its aperture, and how it utilizes it
later on.
Allow RAM pages to be ioremap()-ed too, as long as they are reserved.

Currently, the atags used by kexec are fixed to the ones originally used
to boot the kernel. This is less than ideal as changing the commandline,
initrd and other options would be a useful feature.
This patch exports the atags used for the current kernel to userspace
through an "atags" file in procfs. The presence of the file is
controlled by its own Kconfig option and cleans up several ifdef blocks
into a separate file. The tags for the new kernel are assumed to be at
a fixed location before the kernel image itself. The location of the
tags used to boot the original kernel is unimportant and no longer
saved.

Currently early kernel messages, i.e., those from uncompression, go to the
debugging UART. And if it is enabled in the platform configuration, but
not initialized by the bootloader, the machine hangs, waiting for UART
status change. Besides, having those messages on another UART - typically
the console UART - may be preferrable. This patch allows selecting the
UART in kernel configuration.

On the at91sam9263, IRQs for GPIO banks C and D don't currently work.
This is because banks C, D, and E share one clock and toplevel IRQ, but
the AT91 code setting up and handling GPIO IRQs expects no sharing.
This patch:
- Fixes GPIO IRQ setup and handling to cope with GPIO banks that are
shared like on sam9263 chips, by setting up a list of those banks
and making the IRQ dispatching logic scan that list.
- Precomputes the address of each bank's registers, saving it with
other per-bank data so that it no longer needs to be constantly
recomputed during IRQs and other GPIO operations. That shrinks
hot-path code, while helping the GPIO bank irq updates.
- Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just
means "use the default", which is "both edges" here).

After discussions with Anthony Liguori, it seems that the virtio
balloon can be made even simpler. Here's my attempt.
The device configuration tells the driver how much memory it should
take from the guest (ie. balloon size). The guest feeds the page
numbers it has taken via one virtqueue.
A second virtqueue feeds the page numbers the driver wants back: if
the device has the VIRTIO_BALLOON_F_MUST_TELL_HOST bit, then this
queue is compulsory, otherwise it's advisory (and the guest can simply
fault the pages back in).
This driver can be enhanced later to deflate the balloon via a
shrinker, oom callback or we could even go for a complete set of
in-guest regulators.

As Avi pointed out, as we continue to massage the virtio PCI ABI, we can make
things a little more friendly to users by utilizing the PCI revision field to
indicate which version of the ABI we're using. This is a hard ABI version
and incrementing it will cause the guest driver to break.
This is the necessary changes to virtio_pci to support this.

This patch goes on top of the minor number patch. Please let me know if
you want a merged patch:
Currently virtio_blk creates the disk name combinging "vd" with 'a'++.
This will give strange names after vdz. I have implemented names up to
vdzzz - inspired by the sd.c code. That should be sufficient for now.
There is one driver in the kernel (driver/s390/block/dasd_genhd.c) that
implements names from dasda-dasdzzzz allowing even more disks. Maybe
a janitor can come up with a common implementation usable for all kind
of block device drivers.

Rusty,
currently virtio_blk uses one major number per device. While this works
quite well on most systems it is wasteful and will exhaust major numbers
on larger installations.
This patch allocates a major number on init and will use 16 minor numbers
for each disk. That will allow ~64k virtio_blk disks.

Rusty,
I currently try to make my guest boot from an virtio root device
without having an external kernel. Some of the tools that I tried
expect HDIO_GETGEO to work. The most interesting value is likely
the geo.start value to get the offset of a partition. This value
is filled by block/ioctl.c if fops->getgeo is set. This patch also
fills in some standard values for heads, sectors and cylinders.
