2018-10-29um: Make line/tty semantics use true write IRQAnton Ivanov
This fixes a long standing bug where large amounts of output could freeze the tty (most commonly seen on stdio console). While the bug has always been there it became more pronounced after moving to the new interrupt controller. The line semantics are now changed to have true IRQ write semantics which should further improve the tty/line subsystem stability and performance Signed-off-by: Anton Ivanov <anton.ivanov@cambridgegreys.com> Signed-off-by: Richard Weinberger <richard@nod.at>

2018-10-29um: Drop own definition of PTRACE_SYSEMU/_SINGLESTEPRichard Weinberger
32bit UML used to define PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP own its own because many years ago not all libcs had these request codes in their UAPI. These days PTRACE_SYSEMU/_SINGLESTEP is well known and part of glibc and our own define becomes problematic. With change c48831d0eebf ("linux/x86: sync sys/ptrace.h with Linux 4.14 [BZ #22433]") glibc turned PTRACE_SYSEMU/_SINGLESTEP into a enum and UML failed to build. Let's drop our define and rely on the fact that every libc has PTRACE_SYSEMU/_SINGLESTEP.

2018-10-29i2c: uniphier-f: fix race condition when IRQ is clearedMasahiro Yamada
The current IRQ handler clears all the IRQ status bits when it bails out. This is dangerous because it might clear away the status bits that have just been set while processing the current handler. If this happens, the IRQ event for the latest transfer is lost forever. The IRQ status bits must be cleared *before* the next transfer is kicked.

2018-10-29i2c: uniphier-f: fix occasional timeout errorMasahiro Yamada
Currently, a timeout error could happen at a repeated START condition. For a (non-repeated) START condition, the controller starts sending data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated START condition, the hardware starts running when the slave address is written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is actually unneeded. Because the hardware is already running before the IRQ is enabled for a repeated START, the driver may miss the IRQ event. In most cases, this problem does not show up since modern CPUs are much faster than the I2C transfer. However, it is still possible that a context switch happens after the controller starts, but before the IRQ register is set up. To fix this, - Do not write UNIPHIER_FI2C_CR for repeated START conditions. - Enable IRQ *before* writing the slave address to the TX FIFO. - Disable IRQ for the current CPU while queuing up the TX FIFO; If the CPU is interrupted by some task, the interrupt handler might be invoked due to the empty TX FIFO before completing the setup.

2018-10-29i2c: uniphier-f: make driver robust against concurrencyMasahiro Yamada
This is unlikely to happen, but it is possible for a CPU to enter the interrupt handler just after wait_for_completion_timeout() has expired. If this happens, the hardware is accessed from multiple contexts concurrently. Disable the IRQ after wait_for_completion_timeout(), and do nothing from the handler when the IRQ is disabled.

2018-10-29HID: input: simplify/fix high-res scroll event handlingLinus Torvalds
Commit 1ff2e1a44e02 ("HID: input: Create a utility class for counting scroll events") created the helper function hid_scroll_counter_handle_scroll() to handle high-res scroll events and also expose them as regular wheel events. But the resulting algorithm was unstable, and causes scrolling to be very unreliable. When you hit the half-way mark of the highres multiplier, small highres movements will incorrectly translate into big traditional wheel movements, causing odd jitters. Simplify the code and make the output stable. NOTE! I'm pretty sure this will need further tweaking. But this at least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into a usable one.

The WARN_ON_ONCE(__read_cr3() != build_cr3()) in switch_mm_irqs_off() triggers every once in a while during a snapshotted system upgrade. The warning triggers since commit decab0888e6e ("x86/mm: Remove preempt_disable/enable() from __native_flush_tlb()"). The callchain is: get_page_from_freelist() -> post_alloc_hook() -> __kernel_map_pages() with CONFIG_DEBUG_PAGEALLOC enabled. Disable preemption during CR3 reset / __flush_tlb_all() and add a comment why preemption has to be disabled so it won't be removed accidentaly. Add another preemptible() check in __flush_tlb_all() to catch callers with enabled preemption when PGE is enabled, because PGE enabled does not trigger the warning in __native_flush_tlb().

Pull 9p updates from Dominique Martinet: "Highlights this time around are the end of Matthew's work to remove the custom 9p request cache and use a slab directly for requests, with some extra patches on my end to not degrade performance, but it's a very good cleanup. Tomas and I fixed a few more syzkaller bugs (refcount is the big one), and I had a go at the coverity bugs and at some of the bugzilla reports we had open for a while. I'm a bit disappointed that I couldn't get much reviews for a few of my own patches, but the big ones got some and it's all been soaking in linux-next for quite a while so I think it should be OK. Summary: - Finish removing the custom 9p request cache mechanism - Embed part of the fcall in the request to have better slab performance (msize usually is power of two aligned) - syzkaller fixes: * add a refcount to 9p requests to avoid use after free * a few double free issues - A few coverity fixes - Some old patches that were in the bugzilla: * do not trust pdu content for size header * mount option for lock retry interval" * tag '9p-for-4.20' of git://github.com/martinetd/linux: (21 commits) 9p/trans_fd: put worker reqs on destroy 9p/trans_fd: abort p9_read_work if req status changed 9p: potential NULL dereference 9p locks: fix glock.client_id leak in do_lock 9p: p9dirent_read: check network-provided name length 9p/rdma: remove useless check in cm_event_handler 9p: acl: fix uninitialized iattr access 9p locks: add mount option for lock retry interval 9p: do not trust pdu content for stat item size 9p: Rename req to rreq in trans_fd 9p: fix spelling mistake in fall-through annotation 9p/rdma: do not disconnect on down_interruptible EAGAIN 9p: Add refcount to p9_req_t 9p: rename p9_free_req() function 9p: add a per-client fcall kmem_cache 9p: embed fcall in req to round down buffer allocs 9p: Remove p9_idpool 9p: Use a slab for allocating requests 9p: clear dangling pointers in p9stat_free v9fs_dir_readdir: fix double-free on p9stat_read error ...
