In the commit 03de1921 ("mmc: dw_mmc: introduce timer for broken command transfer over scheme") we tried to calculate the expected hardware command timeout value. Unfortunately that calculation isn't quite correct in all cases. It used "bus_hz" but, as far as I can tell, it's supposed to use the card clock. Let's account for the div value, which is documented as 2x the value stored in the register, or 1 if the register is 0. NOTE: It's not expected that this will actually fix anything important since the 10 ms margin added by the function will pretty much dwarf any calculations. The card clock should be 100 kHz at minimum and: 1000 ms/s * (255 * 2) / 100000 Hz. Gives us 5.1 ms. ...so really the point of this patch is just to make the code more "correct" in case anyone ever tries to remove the 10 ms buffer.

When running with the commit 03de1921 ("mmc: dw_mmc: introduce timer for broken command transfer over scheme") I found this message in the log: Unexpected command timeout, state 7 It turns out that we weren't properly cancelling the new CTO timer in the case that a voltage switch was done. Let's promote the cancel into the dw_mci_cmd_interrupt() function to fix this. Fixes: 03de1921 ("mmc: dw_mmc: introduce timer for broken command transfer over scheme") Tested-by:

Since this driver checks if the return value of dma_map_sg() is minus or not and keeps to enable the DMAC, it may cause kernel panic when the dma_map_sg() returns 0. So, this patch fixes the issue. Reported-by:

Since the commit de3ee99b ("mmc: Delete bounce buffer handling") deletes the bounce buffer handling, a request data size will be referred to max_{req,seg}_size instead of MMC_QUEUE_BOUNCESZ (64k bytes). In other hand, renesas_sdhi_internal_dmac.c will set very big value of max_{req,seg}_size because the max_blk_count is set to 0xffffffff. And then, "swiotlb buffer is full" happens because swiotlb can handle a memory size up to 256k bytes only (IO_TLB_SEGSIZE = 128 and IO_TLB_SHIFT = 11). So, as a workaround, this patch avoids the issue by setting the max_{req,seg}_size up to 256k bytes if swiotlb is running. Reported-by:

Pull watchddog clean-up and fixes from Thomas Gleixner: "The watchdog (hard/softlockup detector) code is pretty much broken in its current state. The patch series addresses this by removing all duct tape and refactoring it into a workable state. The reasons why I ask for inclusion that late in the cycle are: 1) The code causes lockdep splats vs. hotplug locking which get reported over and over. Unfortunately there is no easy fix. 2) The risk of breakage is minimal because it's already broken 3) As 4.14 is a long term stable kernel, I prefer to have working watchdog code in that and the lockdep issues resolved. I wouldn't ask you to pull if 4.14 wouldn't be a LTS kernel or if the solution would be easy to backport. 4) The series was around before the merge window opened, but then got delayed due to the UP failure caused by the for_each_cpu() surprise which we discussed recently. Changes vs. V1: - Addressed your review points - Addressed the warning in the powerpc code which was discovered late - Changed two function names which made sense up to a certain point in the series. Now they match what they do in the end. - Fixed a 'unused variable' warning, which got not detected by the intel robot. I triggered it when trying all possible related config combinations manually.

We trap and emulate some instructions (e.g, mrs, deprecated instructions) for the userspace. However the handlers for these are registered as late_initcalls and the userspace could be up and running from the initramfs by that time (with populate_rootfs, which is a rootfs_initcall()). This could cause problems for the early applications ending up in failure like : [ 11.152061] modprobe[93]: undefined instruction: pc=0000ffff8ca48ff4 This patch promotes the specific calls to core_initcalls, which are guaranteed to be completed before we hit userspace.

There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress(). Signed-off-by:

Pull NVMe fixes from Christoph: "A trivial one-liner from Martin to fix the visible of the uuid attr, and another one (originally from Abhishek Shah, rewritten by me) to fix the CMB addresses passed back to the controller in case of a system that remaps BAR addresses between host and device."

Enforcing exclusive ownership on upper/work dirs caused a docker regression: https://github.com/moby/moby/issues/34672. Euan spotted the regression and pointed to the offending commit. Vivek has brought the regression to my attention and provided this reproducer: Terminal 1: mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none merged/ Terminal 2: unshare -m Terminal 1: umount merged mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none merged/ mount: /root/overlay-testing/merged: none already mounted or mount point busy To fix the regression, I replaced the error with an alarming warning. With index feature enabled, mount does fail, but logs a suggestion to override exclusive dir protection by disabling index. Note that index=off mount does take the inuse locks, so a concurrent index=off will issue the warning and a concurrent index=on mount will fail. Documentation was updated to reflect this change.
