2714021937 USB: Let some USB host controllers get IRQ flags from resource
[This version fixes a thinko in the r8a66597 driver]

This patch let a few discrete USB host controllers drivers (isp116x-hcd,
r8a66597-hcd and sl811-hcd) obtain IRQ flags from their IORESOURCE_IRQ
resource if configured as such, much like it's been done for the smc91x
driver.

It spares people writing support for specific boards the burden to
configure the interrupt controller independantly, and keeps all IRQ
related information in a single resource.

HCD that are integrally part of a SoC have been left aside, as there
is probably no "wiring" options...

Tested on an Xscale PXA-255 based platform with isp116x-hcd.

55b447bf79 USB: kill URBs permanently
looking at usb_kill_urb() it seems to me that it is unnecessarily lenient.
In the use case of disconnect() you never want to use the URB again
(for the same device) But leaving urb->reject elevated will make it easier
to avoid races between read/write and disconnect.

49b707b90c drivers/usb/class/usblp.c: adjust error handling code
In this code, it is possible to tell statically whether usblp will be NULL
in the error handling code.

Oliver Neukum suggested to make a goto to the final return rather than 
return directly.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>

identifier f,err,l,l1;

4b40893918 drm/i915: fix ioremap of a user address for non-root (CVE-2008-3831)
Olaf Kirch noticed that the i915_set_status_page() function of the i915
kernel driver calls ioremap with an address offset that is supplied by
userspace via ioctl. The function zeroes the mapped memory via memset
and tells the hardware about the address. Turns out that access to that
ioctl is not restricted to root so users could probably exploit that to
do nasty things. We haven't tried to write actual exploit code though.

It only affects the Intel G33 series and newer.

673a394b1e drm: Add GEM ("graphics execution manager") to i915 driver.
GEM allows the creation of persistent buffer objects accessible by the
graphics device through new ioctls for managing execution of commands on the
device.  The userland API is almost entirely driver-specific to ensure that
any driver building on this model can easily map the interface to individual
driver requirements.

GEM is used by the 2d driver for managing its internal state allocations and
will be used for pixmap storage to reduce memory consumption and enable
zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

0a3e67a4ca drm: Rework vblank-wait handling to allow interrupt reduction.
Previously, drivers supporting vblank interrupt waits would run the interrupt
all the time, or all the time that any 3d client was running, preventing the
CPU from sleeping for long when the system was otherwise idle.  Now, interrupts
are disabled any time that no client is waiting on a vblank event. The new
method uses vblank counters on the chipsets when the interrupts are turned
off, rather than counting interrupts, so that we can continue to present
accurate vblank numbers.
