2018-03-21ARM: OMAP: Fix SRAM W+X mappingTony Lindgren
We are still using custom SRAM code for some SoCs and are not marking the PM code mapped to SRAM as read-only and executable after we're done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping at address" warning. Let's fix this issue the same way as commit 728bbe75c82f ("misc: sram: Introduce support code for protect-exec sram type") is doing for drivers/misc/sram-exec.c. On omap3, we need to restore SRAM when returning from off mode after idle, so init time configuration is not enough. And as we no longer have users for omap_sram_push_address() we can make it static while at it. Note that eventually we should be using sram-exec.c for all SoCs.

2018-03-21drm/vmwgfx: Fix a destoy-while-held mutex problem.Thomas Hellstrom
When validating legacy surfaces, the backup bo might be destroyed at surface validate time. However, the kms resource validation code may have the bo reserved, so we will destroy a locked mutex. While there shouldn't be any other users of that mutex when it is destroyed, it causes a lock leak and thus throws a lockdep error. Fix this by having the kms resource validation code hold a reference to the bo while we have it reserved. We do this by introducing a validation context which might come in handy when the kms code is extended to validate multiple resources or buffers.

2018-03-21drm/vmwgfx: Fix black screen and device errors when running without fbdevThomas Hellstrom
When we are running without fbdev, transitioning from the login screen to X or gnome-shell/wayland will cause a vt switch and the driver will disable svga mode, losing all modesetting resources. However, the kms atomic state does not reflect that and may think that a crtc is still turned on, which will cause device errors when we try to bind an fb to the crtc, and the screen will remain black. Fix this by turning off all kms resources before disabling svga mode. Cc: <stable@vger.kernel.org> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>

2018-03-21ALSA: hda - Force polling mode on CFL for fixing codec communicationTakashi Iwai
We've observed too long probe time with Coffee Lake (CFL) machines, and the likely cause is some communication problem between the HD-audio controller and the codec chips. While the controller expects an IRQ wakeup for each codec response, it seems sometimes missing, and it takes one second for the controller driver to time out and read the response in the polling mode. Although we aren't sure about the real culprit yet, in this patch, we put a workaround by forcing the polling mode as default for CFL machines; the polling mode itself isn't too heavy, and much better than other workarounds initially suggested (e.g. disabling power-save), at least.

When that happens, the object file doesn't get rebuilt as it should. This is especially the case on filesystems that don't have sub-second time precision, such as ext3 or Ext4 with 128B inodes.
