Brings in various bug fixes from 3.6-rcX
2012-09-05powerpc: Rename 64-bit PVR constants to PVR_fooMichael Ellerman1-9/+9
We have an old FIXME in reg.h which points out that we should standardise on PVR_foo for our PVR #defines. Currently we use PVR_ on 32-bit and PV_ on 64-bit. So do that rename and remove the FIXME. Seeing as we're touching all but one usage of __is_processor(), rename it to something less ugly and more indicative of what it does, which is simply to check the PVR version.

2012-09-05hvc_vio: Improve registration of udbg backendBenjamin Herrenschmidt1-53/+70
The pseries hvterm driver only registers a udbg backend (for xmon and other low level debugging mechanisms) when hvc0 is recognized as the firmware console at boot time, not if it's detected later on, for example because the firmware is using a graphics card. This can make debugging challenging especially under X11, and there's really no good reason for that limitation, so let's hookup udbg whenever hvc0 is detected instead.

2012-09-05hvc_console: Better kernel console supportBenjamin Herrenschmidt1-7/+26
hvc_console has two methods to instanciate the consoles. hvc_instanciate is meant to be called at early boot, while hvc_alloc is called for more dynamically probed objects. Currently, it only deals with adding kernel consoles in the former case, which means for example that if a console only uses dynamic probing, it will never be usable as a kernel console even when specifying console=hvc0 explicitly, which could be considered annoying... More specifically, on pseries, we only do the early instanciate for the console currently used by the firmware, so if you have your firmware configured to go to a video card, for example, you cannot get your kernel console, oops messages, etc... on your serial port or hypervisor console, which would be handy to deal with oopses. This fixes it by checking if hvc_console.flags & CON_ENABLED is set when registering a new dynamic console, and if not, redo the index check and re-register the console if the index matches, allowing console=hvcN to work.

2012-08-30e1000e: DoS while TSO enabled caused by link partner with small MSSBruce Allan2-25/+24
With a low enough MSS on the link partner and TSO enabled locally, the networking stack can periodically send a very large (e.g. 64KB) TCP message for which the driver will attempt to use more Tx descriptors than are available by default in the Tx ring. This is due to a workaround in the code that imposes a limit of only 4 MSS-sized segments per descriptor which appears to be a carry-over from the older e1000 driver and may be applicable only to some older PCI or PCIx parts which are not supported in e1000e. When the driver gets a message that is too large to fit across the configured number of Tx descriptors, it stops the upper stack from queueing any more and gets stuck in this state. After a timeout, the upper stack assumes the adapter is hung and calls the driver to reset it. Remove the unnecessary limitation of using up to only 4 MSS-sized segments per Tx descriptor, and put in a hard failure test to catch when attempting to check for message sizes larger than would fit in the whole Tx ring. Refactor the remaining logic that limits the size of data per Tx descriptor from a seemingly arbitrary 8KB to a limit based on the dynamic size of the Tx packet buffer as described in the hardware specification. Also, fix the logic in the check for space in the Tx ring for the next largest possible packet after the current one has been successfully queued for transmit, and use the appropriate defines for default ring sizes in e1000_probe instead of magic values. This issue goes back to the introduction of e1000e in 2.6.24 when it was split off from e1000.

2012-08-29drm/radeon/atom: powergating fixes for DCE6Alex Deucher1-20/+2
Power gating is per crtc pair, but the powergating registers should be called individually. The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.

On some Fermi chipsets (NVCE particularly) PCOPY1 doesn't exist. And if what I've seen on Kepler is true of Fermi too, chipsets of the same type can have different PCOPY units available. This should fix a v3.5 regression reported by a number of people effecting suspend/resume on NVC8/NVCE chipsets. Cc: stable@vger.kernel.org [3.5] Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
