2013-01-21ttm: on move memory failure don't leave a node danglingDave Airlie
if we have a move notify callback, when moving fails, we call move notify the opposite way around, however this ends up with *mem containing the mm_node from the bo, which means we double free it. This is a follow on to the previous fix. Reviewed-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-01-21ttm: don't destroy old mm_node on memcpy failureDave Airlie
When we are using memcpy to move objects around, and we fail to memcpy due to lack of memory to populate or failure to finish the copy, we don't want to destroy the mm_node that has been copied into old_copy. While working on a new kms driver that uses memcpy, if I overallocated bo's up to the memory limits, and eviction failed, then machine would oops soon after due to having an active bo with an already freed drm_mm embedded in it, freeing it a second time didn't end well.

Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this.

Commit bbb63c514a3464342967237a51a21ea8f61ab951 (drivers:tty:fix up ENOIOCTLCMD error handling) changed the default return value from tty ioctl to be ENOTTY and not EINVAL. This is appropriate. But in case of TIOCGPTN for the old BSD ptys glibc started failing because it expects EINVAL to be returned. Only then it continues to obtain the pts name the other way around. So fix this case by explicit return of EINVAL in this case.

2013-01-17staging: vt6656: Fix inconsistent structure packingBen Hutchings
vt6656 has several headers that use the #pragma pack(1) directive to enable structure packing, but never disable it. The layout of structures defined in other headers can then depend on which order the various headers are included in, breaking the One Definition Rule. In practice this resulted in crashes on x86_64 until the order of header inclusion was changed for some files in commit 11d404cb56ecd ('staging: vt6656: fix headers and add cfg80211.'). But we need a proper fix that won't be affected by future changes to the order of inclusion. This removes the #pragma pack(1) directives and adds __packed to the structure definitions for which packing appears to have been intended.

2013-01-17drm/i915: fix FORCEWAKE posting readsJani Nikula
We stopped reading FORCEWAKE for posting reads in commit 8dee3eea3ccd3b6c00a8d3a08dd715d6adf737dd Author: Ben Widawsky <ben@bwidawsk.net> Date: Sat Sep 1 22:59:50 2012 -0700 drm/i915: Never read FORCEWAKE and started using something from the same cacheline instead. On the bug reporter's machine this broke entering rc6 states after a suspend/resume cycle. It turns out reading ECOBUS as posting read worked fine, while GTFIFODBG did not, preventing RC6 states after suspend/resume per the bug report referenced below. It's not entirely clear why, but clearly GTFIFODBG was nowhere near the same cacheline or address range as FORCEWAKE. Trying out various registers for posting reads showed that all tested registers for which NEEDS_FORCE_WAKE() (in i915_drv.c) returns true work. Conversely, most (but not quite all) registers for which NEEDS_FORCE_WAKE() returns false do not work. Details in the referenced bug. Based on the above, add posting reads on ECOBUS where GTFIFODBG was previously relied on. In true cargo cult spirit, add posting reads for FORCEWAKE_VLV writes as well, but instead of ECOBUS, use FORCEWAKE_ACK_VLV which is in the same address range as FORCEWAKE_VLV. v2: Add more details to the commit message.

2013-01-16s390/chsc: fix SEI usageSebastian Ott
cbc0dd1 "s390/pci: CHSC PCI support for error and availability events" introduced a new SEI notification type as part of pci support. The way SEI was called with nt2 and nt0 consecutive broke the nt0 stuff used for channel subsystem notifications. The reason why this was broken with the mentioned patch is that you cannot selectively disable type 0 notifications (so even when asked for type 2 only, type 0 could be presented). The way to do it is to tell SEI which types of notification you can process and -this is the important part- look at the SEI result which notification type you actually received.

2013-01-16drm/i915: Invalidate the relocation presumed_offsets along the slow pathChris Wilson
In the slow path, we are forced to copy the relocations prior to acquiring the struct mutex in order to handle pagefaults. We forgo copying the new offsets back into the relocation entries in order to prevent a recursive locking bug should we trigger a pagefault whilst holding the mutex for the reservations of the execbuffer. Therefore, we need to reset the presumed_offsets just in case the objects are rebound back into their old locations after relocating for this exexbuffer - if that were to happen we would assume the relocations were valid and leave the actual pointers to the kernels dangling, instant hang.

2013-01-16drm/i915/eDP: do not write power sequence registers for ghost eDPJani Nikula
Some machines detect an eDP port even if it's not really there, and eDP initialization has a fail path for this. Typically such machines have an LVDS display instead. A regression introduced in commit 82ed61fa1a4e08d5f9e86fb1b715b50ed678b6ac Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat Oct 20 20:57:41 2012 +0200 drm/i915: make edp panel power sequence setup more robust updated the power sequence registers PCH_PP_ON_DELAYS, PCH_PP_OFF_DELAYS, and PCH_PP_DIVISOR also in the ghost eDP case, messing up the LVDS display. Split the power sequencer initialization into two, delaying the register updates until after we know the eDP is real. Note: Keep the PP_CONTROL unlocking in the first part, even if it does not update registers, per the commit message of the above mentioned commit.
