The cgroup device whitelist code gets confused when trying to grant
permission to a disk partition that is not currently open. Part of
blkdev_open() includes __blkdev_get() on the whole disk.
Basically, the only ways to reliably allow a cgroup access to a partition
on a block device when using the whitelist are to 1) also give it access
to the whole block device or 2) make sure the partition is already open in
a different context.
The patch avoids the cgroup check for the whole disk case when opening a
partition.

If iga_init() fails, code releases resources and continues to use it. It
seems that after releasing resources 'return' should be.

When we setup up the VMA flags for the mmap flag and we end up using the
fallback mmap functionality we set the vma->vm_flags |= VM_IO. However we
neglect to propagate the flag to the vma->vm_page_prot.
This bug was found when Linux kernel was running under Xen. In that
scenario, any page that has VM_IO flag to it, means that it MUST be a
MMIO/VRAM backend memory , _not_ System RAM. That is what the fbmem.c
does: sets VM_IO, ioremaps the region - everything is peachy.
Well, not exactly. The vm_page_prot does not get the relevant PTE flags
set (_PAGE_IOMAP) which under Xen is a death-kneel to pages that are
referencing real physical devices but don't have that flag set.
This patch fixes this.

Supports all bpp modes.
The PRTCON register is used to disable in-hardware updates of registers
that store start and end addresses of framebuffer memory. This prevents
display corruption in case we do not make it before VSYNC with updating
them atomically. With this feature there is no need to wait for a VSYNC
interrupt before each such update.
