      drm/nouveau: have non-core mmio accesses go through device object · 586c55f6

      Adds an extra layer of indirection to each register access, but it's not
      too bad, and will also go away as pieces are ported.

      drm/nouveau: implement module init functions in nouveau_drm.c · 94580299
      Ben Skeggs authored
      
      
      These currently just call the existing ones in nouveau_drv.c, but will be
      extended in upcoming commits.  This needed to be separated from the current
      code as there will be some header clashes until things are ported.

      drm/nouveau/core: pull in most of the new core infrastructure · 9274f4a9
      Ben Skeggs authored
      
      
      This commit provides most of the infrastructure to support a major overhaul
      of Nouveau's internals coming in the following commits.  This work aims to
      take all the things we've learned over the last several years, and turn that
      into a cleaner architecture that's more maintainable going forward.
      
      RAMHT and MM bits of the new core have been left out for the moment, and
      will be pulled in as I go through the process of porting the code to
      become either subdev or engine modules.
      
      There are several main goals I wanted to achieve through this work:
      
      -- Reduce complexity
      
      The goal here was to make each component of the driver as independent as
      possible, which will ease maintainability and readability, and provide a
      good base for resetting locked up GPU units in the future.
      
      -- Better tracking of GPU units that are required at any given time
      
      This is for future PM work, we'll be able to tell exactly what parts of the
      GPU we need powered at any given point (etc).
      
      -- Expose all available NVIDIA GPUs to the client
      
      In order to support things such as multi-GPU channels, we want to be able
      to expose all the NVIDIA GPUs to the client over a single file descriptor
      so it can send a single push buffer to multiple GPUs.
      
      -- Untangle the core hardware support code from the DRM implementation
      
      This happened initially as an unexpected side-effect of developing the
      initial core infrastructure in userspace, but it turned into a goal of
      the whole project.  Initial benefits will be the availablility of a
      number of userspace tools and tests using the same code as the driver
      itself, but will also be important as I look into some virtualisation
      ideas.
      
      v2: Ben Skeggs <bskeggs@redhat.com>
      - fix duplicate assignments noticed by clang
      - implement some forgotten yelling in error path
      - ensure 64-bit engine mask is used everywhere
      
      v3: Marcin Slusarz <marcin.slusarz@gmail.com>
      - sparse fixes
      - inline nv_printk into nv_assert to prevent recursive inlining issues

      drm/nouveau: restructure source tree, split core from drm implementation · 02a841d4
      Ben Skeggs authored
      
      
      Future work will be headed in the way of separating the policy supplied by
      the nouveau drm module from the mechanisms provided by the driver core.
      
      There will be a couple of major classes (subdev, engine) of driver modules
      that have clearly defined tasks, and the further directory structure change
      is to reflect this.
      
      No code changes here whatsoever, aside from fixing up a couple of include
      file pathnames.

      drm/nouveau/gem: use bo.offset rather than mm_node.start · 3a92d37e

      Won't necessarily be a drm_mm_node in the future, and I can't think of any
      good reason to not use the offset from the bo struct.  There may have been

      drm/nvc0/fence: restore pre-suspend fence buffer context on resume · d6ba6d21
      Ben Skeggs authored
      
      
      Fixes some unfortunate races on resume.  The G84 version of the code doesn't
      need this as "gpuobj"s are automagically suspended/resumed by the core code
      whereas pinned buffer objects are not.

      vfs: dcache: fix deadlock in tree traversal · 8110e16d
      Miklos Szeredi authored
      
      
      IBM reported a deadlock in select_parent().  This was found to be caused
      by taking rename_lock when already locked when restarting the tree
      traversal.
      
      There are two cases when the traversal needs to be restarted:
      
       1) concurrent d_move(); this can only happen when not already locked,
          since taking rename_lock protects against concurrent d_move().
      
       2) racing with final d_put() on child just at the moment of ascending
          to parent; rename_lock doesn't protect against this rare race, so it
          can happen when already locked.
      
      Because of case 2, we need to be able to handle restarting the traversal
      when rename_lock is already held.  This patch fixes all three callers of
      try_to_ascend().
      
      IBM reported that the deadlock is gone with this patch.
      
      [ I rewrote the patch to be smaller and just do the "goto again" if the
        lock was already held, but credit goes to Miklos for the real work.

      qlcnic: Fix scheduling while atomic bug · 68b3f28c

      In the device close path, 'qlcnic_fw_destroy_ctx' and

      'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock
      held resulting in scheduling while atomic bug causing the following
      trace.
      
      I observed that the commit 012dc19a
      
      
      from John Fastabend addresses a similar issue in ixgbevf driver.
      Adopting the same approach used in the commit, this patch uses mdelay

      commit c0357e97
      
       modified bnx2 to switch from
      using ioremap/iounmap to pci_iomap/pci_iounmap.  They missed a spot in the error
      path of bnx2_init_one though.  This patch just cleans that up.

      The LAN8710/LAN8720 chips do have broken the "FlexPWR" smart power-saving
      capability. Enabling it leads to the PHY not being able to detect Link when
      cold-started without cable connected. Thus, make sure this is disabled.

      this patch fixes it by running the usbnet_resume handler.

      um: Preinclude include/linux/kern_levels.h · 9429ec96
      Geert Uytterhoeven authored
      The userspace part of UML uses the asm-offsets.h generator mechanism to
      create definitions for UM_KERN_<LEVEL> that match the in-kernel
      KERN_<LEVEL> constant definitions.
      
      As of commit 04d2c8c8
      
       ("printk: convert
      the format for KERN_<LEVEL> to a 2 byte pattern"), KERN_<LEVEL> is no
      longer expanded to the literal '"<LEVEL>"', but to '"\001" "LEVEL"', i.e.
      it contains two parts.
      
      However, the combo of DEFINE_STR() in
      arch/x86/um/shared/sysdep/kernel-offsets.h and sed-y in Kbuild doesn't
      support string literals consisting of multiple parts. Hence for all
      UM_KERN_<LEVEL> definitions, only the SOH character is retained in the actual
      definition, while the remainder ends up in the comment. E.g. in
      include/generated/asm-offsets.h we get
      
          #define UM_KERN_INFO "\001" /* "6" KERN_INFO */
      
      instead of
      
          #define UM_KERN_INFO "\001" "6" /* KERN_INFO */
      
      This causes spurious '^A' output in some kernel messages:
      
          Calibrating delay loop... 4640.76 BogoMIPS (lpj=23203840)
          pid_max: default: 32768 minimum: 301
          Mount-cache hash table entries: 256
          ^AChecking that host ptys support output SIGIO...Yes
          ^AChecking that host ptys support SIGIO on close...No, enabling workaround
          ^AUsing 2.6 host AIO
          NET: Registered protocol family 16
          bio: create slab <bio-0> at 0
          Switching to clocksource itimer
      
      To fix this:
        - Move the mapping from UM_KERN_<LEVEL> to KERN_<LEVEL> from
          arch/um/include/shared/common-offsets.h to
          arch/um/include/shared/user.h, which is preincluded for all userspace
          parts,
        - Preinclude include/linux/kern_levels.h for all userspace parts, to
          obtain the in-kernel KERN_<LEVEL> constant definitions. This doesn't
          violate the kernel/userspace separation, as include/linux/kern_levels.h
          is self-contained and doesn't expose any other kernel internals.
        - Remove the now unused STR() and DEFINE_STR() macros.
