Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough that we can dispense with the manual force hotplug trigger stuff. This means that hotplug detection is as simple as reading the current hotplug register values. The first time the hotplug detection is activated, the code synchronously waits for a hotplug sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

Tiled buffers have the same alignment requirements regardless of whether the surface is for db, cb, or textures. Previously, the calculations where inconsistent for each buffer type. - Unify the alignment calculations in a common function - Standardize the alignment units (pixels for pitch/height/depth, bytes for base) - properly check the buffer base alignments Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

More recent GCC caused the i8k driver to stop working, on Slackware compiler was upgraded from gcc-4.4.4 to gcc-4.5.1 after which it didn't work anymore, meaning the driver didn't load or gave total nonsensical output. As it turned out the asm(..) statement forgot to mention it modifies the *regs variable. Credits to Andi Kleen and Andreas Schwab for providing the fix.

An old and oft reported bug, is that of the GPU hanging on a MI_WAIT_FOR_EVENT following a mode switch. The cause is that the GPU is waiting on a scanline counter on an inactive pipe, and so waits for a very long time until eventually the user reboots his machine. We can prevent this either by moving the WAIT into the kernel and thereby incurring considerable cost on every swapbuffers, or by waiting for the GPU to retire the last batch that accesses the framebuffer before installing a new one. As mode switches are much rarer than swap buffers, this looks like an easy choice.

Currently, addrconf_ifdown does not delete statically configured IPv6 addresses when the interface is brought down. The intent is that when the interface comes back up the address will be usable again. However, this doesn't actually work, because the system stops listening on the corresponding solicited-node multicast address, so the address cannot respond to neighbor solicitations and thus receive traffic. Also, the code notifies the rest of the system that the address is being deleted (e.g, RTM_DELADDR), even though it is not. Fix it so that none of this state is updated if the address is being kept on the interface. Tested: Added a statically configured IPv6 address to an interface, started ping, brought link down, brought link up again. When link came up ping kept on going and "ip -6 maddr" showed that the host was still subscribed to there Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

Alexey Kuznetsov noticed a regression introduced by commit f1ecd5d9 ("Revert Backoff [v3]: Revert RTO on ICMP destination unreachable") The RTO and timer modification code added to tcp_v4_err() doesn't check sock_owned_by_user(), which if true means we don't have exclusive access to the socket and therefore cannot modify it's critical state. Just skip this new code block if sock_owned_by_user() is true and eliminate the now superfluous sock_owned_by_user() code block contained within.

Now with improved comma support. On parsing malformed X.25 facilities, decrementing the remaining length may cause it to underflow. Since the length is an unsigned integer, this will result in the loop continuing until the kernel crashes.
