2015-09-23Update inteldrm to the code from Linux 3.14.52 (which corresponds tokettenis88-15114/+36258
commit 48f8f36a6c8018c2b36ea207aaf68ef5326c5075 on the linux-3.14.y branch of the linux-stable tree). This brings preliminary support for the GPU on Intel's Broadwell CPUs. Don't expect these to work perfectly yet. There are some remaining issues with older hardware as well, but no significant regressions have been uncovered. This also updates some of drm core code. The radeondrm code remains based on Linux 3.8 with some minimal canges to adjust to changes in the core drm APIs. Joint effort with jsg@, who did the initial update of the relevant drm core bits. Committing this early to make sure it gets more testing and make it possible for others to help getting the remaining wrinkles straightened out.

intr_barrier(9) to avoid having the interrupt handler touch the rx data structures while we're brining down the interface. This actually reverts many of the changes in rev. 1.300. ok mikeb@

2015-09-18More ifmedia64 fallout.miod2-8/+5
2015-09-18make vmx(4) interrupts mpsafe.dlg1-63/+97
the vmx rx path is only touched in the interrupt handler, so it is already guaranteed to be accessed by only one cpu at a time. the tx path has been massaged so the the producer is only touched by the start routine, and the consumer is only touched by the interrupt path, and can therefore be run concurrently. the only interlock is a count of the free descriptors. if txintr clears IFF_OACTIVE, it takes the kernel lock before running the start routine. other interrupts, eg, link state handling, take the kernel lock.

2015-09-11Make room for media types of the future. Extend the ifmedia word to 64 bits.stsp33-102/+104
This changes numbers of the SIOCSIFMEDIA and SIOCGIFMEDIA ioctls and grows struct ifmediareq. Old ifconfig and dhclient binaries can still assign addresses, however the 'media' subcommand stops working. Recompiling ifconfig and dhclient with new headers before a reboot should not be necessary unless in very special circumstances where non-default media settings must be used to get link and console access is not available. There may be some MD fallout but that will be cleared up later. ok deraadt miod with help and suggestions from several sharks attending l2k15
