So we made the quirk generic and fixed both the graphic and audio drivers properly to use it. Without that, ppc64 server machines will crash at boot with a radeon adapter.

2014-11-25Merge branch 'ipv6_vxlan_outer_udp_csum'David S. Miller
Alexander Duyck says: ==================== Fix outer UDP checksums for IPv6 VXLAN tunnels In testing against an older kernel I found a couple issues in the IPv6 VXLAN tunnel checksum logic for the outer UDP checksum. First the default transitioned from using an outer checksum to not using one. Second, sometime after that the checksum inputs were changed resulting the checksum not being correct if it were computed. These two issues prevented a ping from the newer kernel to the older one. With these two changes applied I verified I was able to send traffic over the VXLAN tunnel to a link partner on an older kernel. The boolean flip fix can be submitted for 3.17 stable as well since the patch that introduced the issue was included in that kernel. ==================== Signed-off-by: David S.

2014-11-24spi: spi-mxs: Fix mapping from vmalloc-ed buffer to scatter listCharles Keepax
We can only use page_address on memory that has been mapped using kmap, when the buffer passed to the SPI has been allocated by vmalloc the page has not necessarily been mapped through kmap. This means sometimes page_address will return NULL causing the pointer we pass to sg_init_one to be invalid. Currently, this issue doesn't show up on the MXS architecture as the defconfig defines CONFIG_HIGHMEM=n which means all pages are mapped. For the sake of robustness though it is best to correct the issue. As we only call page_address so that we can pass a virtual address to sg_init_one which will eventually call virt_to_page on it, fix this by calling sg_set_page directly rather then relying on the sg_init_one helper. Note this patch is only build tested as I don't have an MXS system to test on. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>

This is a driver for the Amlogic Meson SPIFC (SPI flash controller), which is one of the two SPI controllers available on the SoC. It doesn't support DMA and has a 64-byte unified transmit/receive buffer. The device is optimized for interfacing with SPI NOR memories and allows the execution of standard operations such as read, page program, sector erase, etc. in a simplified way, toggling a bit in a dedicated register.

2014-11-24drm/i915: Ignore SURFLIVE and flip counter when the GPU gets resetVille Syrjälä
During a GPU reset we need to get pending page flip cleared out since the ring contents are gone and flip will never complete on its own. This used to work until the mmio vs. CS flip race detection came about. That piece of code is looking for a specific surface address in the SURFLIVE register, but as a flip to that address may never happen the check may never pass. So we should just skip the SURFLIVE and flip counter checks when the GPU gets reset. intel_display_handle_reset() tries to effectively complete the flip anyway by calling .update_primary_plane(). But that may not satisfy the conditions of the mmio vs. CS race detection since there's no guarantee that a modeset didn't sneak in between the GPU reset and intel_display_handle_reset(). Such a modeset will not wait for pending flips due to the ongoing GPU reset, and then the primary plane updates performed by intel_display_handle_reset() will already use the new surface address, and thus the surface address the flip is waiting for might never appear in SURFLIVE. The result is that the flip will never complete and attempts to perform further page flips will fail with -EBUSY. During the GPU reset intel_crtc_has_pending_flip() will return false regardless, so the deadlock with a modeset vs. the error work acquiring crtc->mutex was avoided. And the reset_counter check in intel_crtc_has_pending_flip() actually made this bug even less severe since it allowed normal modesets to go through even though there's a pending flip. This is a regression introduced by me here: commit 75f7f3ec600524c9544cc31695155f1a9ddbe1d9 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Tue Apr 15 21:41:34 2014 +0300 drm/i915: Fix mmio vs. CS flip race on ILK+ Testcase: igt/kms_flip/flip-vs-panning-vs-hang Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: stable@vger.kernel.org Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2014-11-24MIPS: cpu-probe: Set the FTLB probability bit on supported coresMarkos Chandras
Make use of the Config6/FLTBP bit to set the probability of a TLBWR instruction to hit the FTLB or the VTLB. A value of 0 (which may be the default value on certain cores, such as proAptiv or P5600) means that a TLBWR instruction will never hit the VTLB which leads to performance limitations since it effectively decreases the number of available TLB slots.

Commit 078a55fc824c1 ("Delete __cpuinit/__CPUINIT usage from MIPS code") removed our __CPUINIT directives, so now the ".previous" directives are superfluous. Remove them.

2014-11-24MIPS: r4kcache: Add EVA case for protected_writeback_dcache_lineMarkos Chandras
Commit de8974e3f76c0 ("MIPS: asm: r4kcache: Add EVA cache flushing functions") added cache function for EVA using the cachee instruction. However, it didn't add a case for the protected_writeback_dcache_line. mips_dsemul() calls r4k_flush_cache_sigtramp() which in turn uses the protected_writeback_dcache_line() to flush the trampoline code back to memory. This used the wrong "cache" instruction leading to random userland crashes on non-FPU cores.
