Bugzilla Bug #9457
Add refcounting of user waiters to the DRM hardware lock, so that we can use
DRM_LOCK_CONT flag more conservatively.
Also add a kernel waiter refcount that if nonzero transfers the lock for the
kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager

The overflows could lead to the AGP aperture overlapping the framebuffer are in the card's address space when the latter is located at the very end of th 32 bit address space, which would result in a freeze on X server startup,
probably because the card read commands from the framebuffer instead of from AGP.

The Bluetooth host adapters are attached to the Bluetooth class and the
low-level connections are children of these class devices. Having class
devices as parent of bus devices breaks a lot of reasonable assumptions
about sysfs. The host adapters should be attached to the Bluetooth bus
to simplify the dependency resolving. For compatibility an additional
symlink from the Bluetooth class will be used.

The L2CAP and HCI setsockopt() implementations have a small information
leak that makes it possible to leak kernel stack memory to userspace.
If the optlen parameter is 0, no data will be copied by copy_from_user(),
but the uninitialized stack buffer will be read and stored later. A call
to getsockopt() can now retrieve the leaked information.
To fix this problem the stack buffer given to copy_from_user() must be
initialized with the current settings.

Spurious interrupts are often encountered especially on systems
using the 8259 PIC mode. This is because the I/O write to deassert
the interrupt is posted and won't get to the chip immediately. As
a result, the IRQ may remain asserted after the IRQ handler exits,
causing spurious interrupts.
Flush the interrupt mailbox in non-MSI handlers to de-assert the
IRQ immediately. This seems to be the most straight forward approach
after discussion with Jeff Garzik and David Miller.

Some minor refactoring in the generic code was necessary for
this:
1) This controller requires 8-byte access to the interrupt map
and clear register. They are 64-bits on all the other
SBUS and PCI controllers anyways, so this was easy to cure.
2) The IMAP register has a different layout and some bits that we
need to preserve, so use a read/modify/write when making
changes to the IMAP register in generic code.
3) Flushing the entire IOMMU TLB is best done with a single write
to a register on this PCI controller, add a iommu->iommu_flushinv
for this.
Still lacks MSI support, that will come later.
