client_managed field in syncpoint structure was defined as an
integer. The field holds, however, only a boolean value. This patch
modifies the type to boolean.

This patch fixes a bad memory access in syncpoint request code. If
no syncpoints were available, the code accessed unreserved memory
area causing unexpected behaviour.

The firewall verified gather buffers before copying them. This
allowed a malicious application to rewrite the buffer content by
timing the rewrite carefully.
This patch makes the buffer validation occur after copying the
buffers.

The firewall was reinitialised for each gather. Because the filter
was reinitialised, it did not track the class over gather boundaries.
This allowed the user application to set host1x class to one class
in one gather and use that class in another gather without firewall
having knowledge about that.

The firewall assumed that the user space always delivers a relocation
table when it is accessing address registers. If userspace did not
deliver a relocation table and tried to access the address registers,
the code performed bad memory accesses.
This patch modifies the firewall to check correctly that the firewall
table is available before accessing it. In addition, check_reloc() is
converted to use boolean return value (true when the reloc is valid,
false when invalid).

The firewall code used a wrong loop condition (pointer to a
structure) while checking INCR opcode. This patch fixes the code to
use correct loop condition (number of words remaining).

Since the Tegra DRM driver doesn't use the drm_irq_install() helper, the
irq_enabled flag needs to be set manually in order to make functionality
such as the DRM_IOCTL_WAIT_VBLANK work properly.

Add host1x, the driver for host1x and its client unit 2D. The Tegra
host1x module is the DMA engine for register access to Tegra's
graphics- and multimedia-related modules. The modules served by
host1x are referred to as clients. host1x includes some other
functionality, such as synchronization.
