drm_atomic_helper_wait_for_vblanks will go away in the future. The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits have completed flipping before the commit_tail returns. This must be ensured by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do a less agressive wait, which is fine for imx-drm.

Commit d178e034 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature to dpi code") replaced usage of platform data version with SoC matching to configure DPI VDDS. The SoC match entries were incorrect, they should have matched on the machine name instead of the SoC family. Fix it. The result was observed on OpenPandora with OMAP3530 where the panel only had the Blue channel and Red&Green were missing. It was not observed on GTA04 with DM3730.

I believe the intention of the commit 2c9fc9bf ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions, like omap4460. By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a same way as it would treat omap4430 ES1.x This breaks HDMI audio on OMAP4460 devices (PandaES for example). Correct the match rule so we are not going to get false positive match.

Support the "cec" optional clock. The documentation already mentions "cec" optional clock and it is used by several boards, but currently the driver doesn't enable it, thus preventing cec from working on those boards. And even worse: a /dev/cecX device will appear for those boards, but it won't be functioning without configuring this clock. Changes: v4: - Change commit message to stress the importance of this patch v3: - Drop useless braces v2: - Separate ENOENT errors from others - Propagate other errors (especially -EPROBE_DEFER) Signed-off-by: NPierre-Hugues Husson <phh@phh.me> Signed-off-by: NArchit Taneja <architt@codeaurora.org> Link: https://patchwork.freedesktop.org/patch/msgid/20171125201844.11353-1-phh@phh.me

If the device tree for a board did not specify a cec clock, then adv7511_cec_init would return an error, which would cause adv7511_probe() to fail and thus there is no HDMI output. There is no need to have adv7511_probe() fail if the CEC initialization fails, so just change adv7511_cec_init() to a void function. In addition, adv7511_cec_init() should just return silently if the cec clock isn't found and show a message for any other errors. An otherwise correct cleanup patch from Dan Carpenter turned this broken failure handling into a kernel Oops, so bisection points to commit 7af35b0a ("drm/kirin: Checking for IS_ERR() instead of NULL") rather than 3b1b9750 ("drm: adv7511/33: add HDMI CEC support").

hugetlfs_fallocate() currently performs put_page() before unlock_page(). This scenario opens a small time window, from the time the page is added to the page cache, until it is unlocked, in which the page might be removed from the page-cache by another core. If the page is removed during this time windows, it might cause a memory corruption, as the wrong page will be unlocked. It is arguable whether this scenario can happen in a real system, and there are several mitigating factors. The issue was found by code inspection (actually grep), and not by actually triggering the flow. Yet, since putting the page before unlocking is incorrect it should be fixed, if only to prevent future breakage or someone copy-pasting this code. Mike said: "I am of the opinion that this does not need to be sent to stable. Although the ordering is current code is incorrect, there is no way for this to be a problem with current locking. In addition, I verified that the perhaps bigger issue with sys_fadvise64(POSIX_FADV_DONTNEED) for hugetlbfs and other filesystems is addressed in 3a77d214 ("mm: fadvise: avoid fadvise for fs without backing device")" Link: http://lkml.kernel.org/r/20170826191124.51642-1-namit@vmware.com Fixes: 70c3547e ("hugetlbfs: add hugetlbfs_fallocate()") Signed-off-by: NNadav Amit <namit@vmware.com> Reviewed-by: NMike Kravetz <mike.kravetz@oracle.com> Acked-by: NMichal Hocko <mhocko@suse.com> Cc: Eric Biggers <ebiggers3@gmail.com> Cc: Mike Kravetz <mike.kravetz@oracle.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

I made a mistake during converting hugetlb code to 5-level paging: in huge_pte_alloc() we have to use p4d_alloc(), not p4d_offset(). Otherwise it leads to crash -- NULL-pointer dereference in pud_alloc() if p4d table is not yet allocated. It only can happen in 5-level paging mode. In 4-level paging mode p4d_offset() always returns pgd, so we are fine.

Commit 42f46148 ("autofs: fix AT_NO_AUTOMOUNT not being honored") allowed the fstatat(2) system call to properly honor the AT_NO_AUTOMOUNT flag but introduced a semantic change. In order to honor AT_NO_AUTOMOUNT a semantic change was made to the negative dentry case for stat family system calls in follow_automount(). This changed the unconditional triggering of an automount in this case to no longer be done and an error returned instead. This has caused more problems than I expected so reverting the change is needed. In a discussion with Neil Brown it was concluded that the automount(8) daemon can implement this change without kernel modifications. So that will be done instead and the autofs module documentation updated with a description of the problem and what needs to be done by module users for this specific case.

While commit 092a5345 ("autofs: take more care to not update last_used on path walk") helped (partially) resolve a problem where automounts were not expiring due to aggressive accesses from user space it has a side effect for very large environments. This change helps with the expire problem by making the expire more aggressive but, for very large environments, that means more mount requests from clients. When there are a lot of clients that can mean fairly significant server load increases. It turns out I put the last_used in this position to solve this very problem and failed to update my own thinking of the autofs expire policy. So the patch being reverted introduces a regression which should be fixed.
