Pull s390 updates from Vasily Gorbik: - Improve stop_machine wait logic: replace cpu_relax_yield call in generic stop_machine function with a weak stop_machine_yield function. This is overridden on s390, which yields the current cpu to the neighbouring cpu after a couple of retries, instead of blindly giving up the cpu to the hipervisor. This significantly improves stop_machine performance on s390 in overcommitted scenarios. This includes common code changes which have been Acked by Peter Zijlstra and Thomas Gleixner. - Improve jump label transformation speed: transform jump labels without using stop_machine. - Refactoring of the vfio-ccw cp handling, simplifying the code and avoiding unneeded allocating/copying. - Various vfio-ccw fixes (ccw translation, state machine). - Add support for vfio-ap queue interrupt control in the guest. This includes s390 kvm changes which have been Acked by Christian Borntraeger. - Add protected virtualization support for virtio-ccw. - Enforce both CONFIG_SMP and CONFIG_HOTPLUG_CPU, which allows to remove some code which most likely isn't working at all, besides that s390 didn't even compile for !CONFIG_SMP. - Support for special flagged EP11 CPRBs for zcrypt. - Handle PCI devices with no support for new MIO instructions. - Avoid KASAN false positives in reworked stack unwinder. - Couple of fixes for the QDIO layer. - Convert s390 specific documentation to ReST format. - Let s390 crypto modules return -ENODEV instead of -EOPNOTSUPP if hardware is missing. This way our modules behave like most other modules and which is also what systemd's systemd-modules-load.service expects. - Replace defconfig with performance_defconfig, so there is one config file less to maintain. - Remove the SCLP call home device driver, which was never useful. - Cleanups all over the place. * tag 's390-5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (83 commits) docs: s390: s390dbf: typos and formatting, update crash command docs: s390: unify and update s390dbf kdocs at debug.c docs: s390: restore important non-kdoc parts of s390dbf.rst vfio-ccw: Fix the conversion of Format-0 CCWs to Format-1 s390/pci: correctly handle MIO opt-out s390/pci: deal with devices that have no support for MIO instructions s390: ap: kvm: Enable PQAP/AQIC facility for the guest s390: ap: implement PAPQ AQIC interception in kernel vfio: ap: register IOMMU VFIO notifier s390: ap: kvm: add PQAP interception for AQIC s390/unwind: cleanup unused READ_ONCE_TASK_STACK s390/kasan: avoid false positives during stack unwind s390/qdio: don't touch the dsci in tiqdio_add_input_queues() s390/qdio: (re-)initialize tiqdio list entries s390/dasd: Fix a precision vs width bug in dasd_feature_list() s390/cio: introduce driver_override on the css bus vfio-ccw: make convert_ccw0_to_ccw1 static vfio-ccw: Remove copy_ccw_from_iova() vfio-ccw: Factor out the ccw0-to-ccw1 transition vfio-ccw: Copy CCW data outside length calculation ...

When the blk-mq debugfs file creation logic was "cleaned up" it was cleaned up too much, causing the queue file to not be created in the correct location. Turns out the check for the directory being present is needed as if that has not happened yet, the files should not be created, and the function will be called later on in the initialization code so that the files can be created in the correct location.

For non-static-inlines, debug.c already had non-compliant function header docs. So move the pure prototype kdocs of ("s390: include/asm/debug.h add kerneldoc markups") from debug.h to debug.c and merge them with the old function docs. Also, I had the impression that kdoc typically is at the implementation in the compile unit rather than at the prototype in the header file. While at it, update the short kdoc description to distinguish the different functions. And a few more consistency cleanups. Added a new kdoc for debug_set_critical() since debug.h comments it as part of the API.

由 Zhang Lei 提交于
The original implementation of vq_present() relied on aggressive inlining in order for the compiler to know that the code is correct, due to some const-casting issues. This was causing sparse and clang to complain, while GCC compiled cleanly. Commit 0c529ff7 addressed this problem, but since vq_present() is no longer a function, there is now no implicit casting of the returned value to the return type (bool). In set_sve_vls(), this uncast bit value is compared against a bool, and so may spuriously compare as unequal when both are nonzero. As a result, KVM may reject valid SVE vector length configurations as invalid, and vice versa. Fix it by forcing the returned value to a bool.

One space is left unused in circular FIFO to differentiate 'full' and 'empty' cases. So take that in to account while counting for the descriptors completed.

It is possible for an irq triggered by channel0 to be received later after clks are disabled once firmware loaded during sdma probe. If that happens then clearing them by writing to SDMA_H_INTR won't work and the kernel will hang processing infinite interrupts. Actually, don't need interrupt triggered on channel0 since it's pollling SDMA_H_STATSTOP to know channel0 done rather than interrupt in current code, just clear BD_INTR to disable channel0 interrupt to avoid the above case. This issue was brought by commit 1d069bfa ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") which didn't take care the above case.

If probe() fails anywhere beyond the point where sdma_get_firmware() is called, then a kernel oops may occur. Problematic sequence of events: 1. probe() calls sdma_get_firmware(), which schedules the firmware callback to run when firmware becomes available, using the sdma instance structure as the context 2. probe() encounters an error, which deallocates the sdma instance structure 3. firmware becomes available, firmware callback is called with deallocated sdma instance structure 4. use after free - kernel oops ! Solution: only attempt to load firmware when we're certain that probe() will succeed. This guarantees that the firmware callback's context will remain valid. Note that the remove() path is unaffected by this issue: the firmware loader will increment the driver module's use count, ensuring that the module cannot be unloaded while the firmware callback is pending or running.

The "pending" variable was a u32 but we cast it to an unsigned long pointer when we do the for_each_set_bit() loop. The problem is that on big endian 64bit systems that results in an out of bounds read.

When processing Format-0 CCWs, we use the "len" variable as the number of CCWs to convert to Format-1. But that variable contains zero here, and is not a meaningful CCW count until ccwchain_calc_length() returns. Since that routine requires and expects Format-1 CCWs to identify the chaining behavior, the format conversion must be done first. Convert the 2KB we copied even if it's more than we need.

drm/imx: fix stale vblank timestamp after a modeset This series fixes stale vblank timestamps in the first event sent after a crtc was disabled. The core now is notified via drm_crtc_vblank_off before sending the last pending event in atomic_disable. If the crtc is reenabled right away during to a modeset, the event is not sent at all, as the next vblank will take care of it.
