      printk: Correctly handle preemption in console_unlock() · 257ab443
      Petr Mladek authored
      Some console drivers code calls console_conditional_schedule()
      that looks at @console_may_schedule. The value must be cleared
      when the drivers are called from console_unlock() with
      interrupts disabled. But rescheduling is fine when the same
      code is called, for example, from tty operations where the
      console semaphore is taken via console_lock().
      
      This is why @console_may_schedule is cleared before calling console
      drivers. The original value is stored to decide if we could sleep
      between lines.
      
      Now, @console_may_schedule is not cleared when we call
      console_trylock() and jump back to the "again" goto label.
      This has become a problem, since the commit 6b97a20d
      ("printk: set may_schedule for some of console_trylock() callers").
      @console_may_schedule might get enabled now.
      
      There is also the opposite problem. console_lock() can be called
      only from preemptive context. It can always enable scheduling in
      the console code. But console_trylock() is not able to detect it
      when CONFIG_PREEMPT_COUNT is disabled. Therefore we should use the
      original @console_may_schedule value after re-acquiring
      the console semaphore in console_unlock().
      
      This patch solves both problems by moving the "again" goto label.
      
      Alternative solution was to clear and restore the value around
      call_console_drivers(). Then console_conditional_schedule() could
      be used also inside console_unlock(). But there was a potential race
      with console_flush_on_panic() as reported by Sergey Senozhatsky.
      That function should be called only where there is only one CPU
      and with interrupts disabled. But better be on the safe side
      because stopping CPUs might fail.
      
      Fixes: 6b97a20d ("printk: set may_schedule for some of console_trylock() callers")

      printk: use console_trylock() in console_cpu_notify() · 64ca752d
      Sergey Senozhatsky authored
      There is no need to always call blocking console_lock() in
      console_cpu_notify(), it's quite possible that console_sem can
      be locked by other CPU on the system, either already printing
      or soon to begin printing the messages. console_lock() in this
      case can simply block CPU hotplug for unknown period of time
      (console_unlock() is time unbound). Not that hotplug is very
      fast, but still, with other CPUs being online and doing
      printk() console_cpu_notify() can stuck.
      
      Use console_trylock() instead and opt-out if console_sem is
      already acquired from another CPU, since that CPU will do
      the printing for us.

       "Highlights include:
      
         - Support for direct mapped LPC on POWER9, giving Linux direct access

         - Memory hotplug support for the Power9 Radix MMU.
      
         - Add new AUX vectors describing the processor's cache geometry, to
           be used by glibc.
      
         - The ability for a guest to ask the hypervisor to resize the guest's
           hash table, and in addition support for doing so automatically when
           memory is hotplugged into/out-of the guest. This allows the hash
           table to be sized based on the current memory usage of the guest,
           rather than the maximum possible memory usage.
      
         - Implementation of optprobes (kprobe optimisation) for powerpc.
      
        In addition there's the topic branch shared with the KVM tree, which
        includes support for guests to use the Radix MMU on Power9.

      Linus Torvalds authored
      Pull pin control updates from Linus Walleij:
       "Pin control bulk changes for the v4.11 kernel cycle.
      
        Core changes:
      
         - Switch the generic pin config argument from 16 to 24 bits, only use
           8 bits for the configuration type. We might need to encode more
           information about a certain setting than we need to encode
           different generic settings.
      
         - Add a cross-talk API to the pin control GPIO back-end, utilizing
           pinctrl_gpio_set_config() from GPIO drivers that want to set up a
           certain pin configuration in the back-end.
      
           This also includes the .set_config() refactoring of the GPIO chips,
           so that they pass a generic configuration for things like
           debouncing and single ended (typically open drain). This change has
           also been merged in an immutable branch to the GPIO tree.
      
         - Take hogs with a delayed work, so that we finalize probing a pin
           controller before trying to get any hogs.
      
         - For pin controllers putting all group and function definitions into
           the device tree, we now have generic code to deal with this and it
           is used in two drivers so far.
      
         - Simplifications of the pin request conflict check.
      
         - Make dt_free_map() optional.
      
        Updates to drivers:
      
         - pinctrl-single now use the generic helpers to generate dynamic
           group and function tables from the device tree.
      
         - Texas Instruments IOdelay configuration driver add-on to
           pinctrl-single.
      
         - i.MX: use radix trees to store groups and functions, use the new
           generic group and function helpers to manage them.
      
         - Intel: add support for hardware debouncing and 1K pull-down. New
           subdriver for the Gemini Lake SoC.
      
         - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
           MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
      
         - Aspeed: use syscon cross-dependencies to set up related bits in the
           LPC host controller and display controller.
      
         - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
           Add banks Y, Z, AA, AB and AC.
      
         - AMD: support additional GPIO.
      
         - STM32: set this controller to strict muxing mode. STM32H743 MCU
           support.
      
         - Allwinner sunxi: deep simplifications on how to support subvariants
           of SoCs without adding to much SoC-specific data for each
           subvariant, especially for sun5i variants. New driver for V3s SoCs.
           New driver for the H5 SoC. Support A31/A31s variants with the new
           variant framework.
      
         - Mvebu: simplifications to use a MMIO and regmap abstraction. New
           subdrivers for the 98DX3236, 98DX5241 SoCs.
      
         - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC

      HID: rmi: fallback to generic/multitouch if hid-rmi is not built · 2fa299a9
      Jiri Kosina authored
      Commit 279967a6 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
      unconditionally switches over handling of all Synaptics touchpads to hid-rmi
      (to make use of extended features of the HW); in case CONFIG_HID_RMI is
      disabled though this renders the touchpad unusable, as the
      
      	HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)
      
      match doesn't exist and generic/multitouch doesn't bind to it either (due
      to hid group mismatch).
      
      Fix this by switching over to hid-rmi only if it has been actually built.

      Pull exception table module split from Paul Gortmaker:
       "Final extable.h related changes.
      
        This completes the separation of exception table content from the
        module.h header file. This is achieved with the final commit that
        removes the one line back compatible change that sourced extable.h
        into the module.h file.
      
        The commits are unchanged since January, with the exception of a
        couple Acks that came in for the last two commits a bit later. The
        changes have been in linux-next for quite some time[1] and have got
        widespread arch coverage via toolchains I have and also from
        additional ones the kbuild bot has.
      
        Maintaners of the various arch were Cc'd during the postings to
        lkml[2] and informed that the intention was to take the remaining arch
        specific changes and lump them together with the final two non-arch
        specific changes and submit for this merge window.
      
        The ia64 diffstat stands out and probably warrants a mention. In an
        earlier review, Al Viro made a valid comment that the original header
        separation of content left something to be desired, and that it get
        fixed as a part of this change, hence the larger diffstat"

      module: fix memory leak on early load_module() failures · a5544880
      Luis R. Rodriguez authored
      While looking for early possible module loading failures I was
      able to reproduce a memory leak possible with kmemleak. There
      are a few rare ways to trigger a failure:
      
        o we've run into a failure while processing kernel parameters
          (parse_args() returns an error)
        o mod_sysfs_setup() fails
        o we're a live patch module and copy_module_elf() fails
      
      Chances of running into this issue is really low.

      Linus Torvalds authored
      Pull device mapper updates from Mike Snitzer:
      
       - Fix dm-raid transient device failure processing and other smaller
         tweaks.
      
       - Add journal support to the DM raid target to close the 'write hole'
         on raid 4/5/6.
      
       - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB.
      
       - Add 'metadata2' feature to dm-cache to separate the dirty bitset out
         from other cache metadata. This improves speed of shutting down a
         large cache device (which implies writing out dirty bits).
      
       - Fix a memory leak during dm-stats data structure destruction.
      
       - Fix a DM multipath round-robin path selector performance regression
         that was caused by less precise balancing across all paths.
      
       - Lastly, introduce a DM core fix for a long-standing DM snapshot
         deadlock that is rooted in the complexity of the device stack used in
         conjunction with block core maintaining bios on current->bio_list to
         manage recursion in generic_make_request(). A more comprehensive fix
         to block core (and its hook in the cpu scheduler) would be wonderful
         but this DM-specific fix is pragmatic considering how difficult it
         has been to make progress on a generic fix.

      usercopy: Add tests for all get_user() sizes · 4c5d7bc6
      Kees Cook authored
      
      
      The existing test was only exercising native unsigned long size
      get_user(). For completeness, we should check all sizes. But we
      must skip some 32-bit architectures that don't implement a 64-bit
      get_user().
      
      These new tests actually uncovered a bug in ARM's 64-bit get_user()
      zeroing.
