      [SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.c · 8163904e
      David S. Miller 提交于
      They are handled in a ->compat_ioctl() handler, so it's just noise
      when compat_ioctl.c warns which occurs when they are used on non-SBUS
      framebuffer devices.

      [SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling. · ad7ad57c
      David S. Miller 提交于
      Fully unify all of the DMA ops so that subordinate bus types to
      the DMA operation providers (such as ebus, isa, of_device) can
      work transparently.
      
      Basically, we just make sure that for every system device we
      create, the dev->archdata 'iommu' and 'stc' fields are filled
      in.
      
      Then we have two platform variants of the DMA ops, one for SUN4U which
      actually programs the real hardware, and one for SUN4V which makes
      hypervisor calls.
      
      This also fixes the crashes in parport_pc on sparc64, reported by
      Meelis Roos.

      [VIDEO]: Fix OOPS in all SBUS framebuffer drivers. · c7f439b9
      David S. Miller 提交于
      All of these drivers use a silly:
      
      struct all_info {
      	struct fb_info info;
      	struct foo_par par;
      };
      
      struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL);
      all->info.par = &all->par;
      
      etc. etc. code sequence, basically replicating the provided
      framebuffer_alloc()/framebuffer_release(), and doing it badly.
      
      Not only is this massive code duplication, it also caused a
      bug in that we weren't setting the fb_info->device pointer
      which results in an OOPS when fb_is_primary_device() runs.
      
      Fix all of this by using framebuffer_{alloc,release}() and
      passing in "&of_device->dev" as the device pointer.

      Gabriel C reports lguest doesn't compile with CONFIG_BLOCK=n.  Fix this
      by introducing a config var for the block device, which depends on

      Remove fs.h from mm.h. For this,
       1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
       2) Add back fs.h or less bloated headers (err.h) to files that need it.
      
      As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
      rebuilt down to 3444 (-12.3%).

      Introduce CONFIG_SUSPEND for suspend-to-Ram and standby · 296699de
      Rafael J. Wysocki 提交于
      Introduce CONFIG_SUSPEND representing the ability to enter system sleep
      states, such as the ACPI S3 state, and allow the user to choose SUSPEND
      and HIBERNATION independently of each other.
      
      Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
      been chosen and the kernel is intended for SMP systems.
      
      Also, introduce CONFIG_PM_SLEEP which is automatically selected if
      CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
      code needed for both suspend and hibernation.
      
      The top-level power management headers and the ACPI code related to
      suspend and hibernation are modified to use the new definitions (the
      changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
      the number of ifdefs).
      
      There are many other files in which CONFIG_PM can be replaced with
      CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
      the future.

      [SCSI] aacraid: fix Sunrise Lake reset handling · 9859c1aa
      Salyzyn, Mark 提交于
      The patch is *much* smaller than the description. I am attempting to
      answer to those that want to understand an issue that was reported in
      May this year.
      
      If a Sunrise Lake based card that requires an alternate reset mechanism
      is set up to ignore the commanded IOP_RESET it reports 0x00000010
      (IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism
      to reset all cores), and thus the reset platform function decides to
      switch to IOP_RESET_ALWAYS because the reset platform function
      parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS
      then responds with the 0x3803000F return code, but alas we treat this as
      an error instead of using the alternate reset mechanism (put a 0x03 into
      the register offset 0x38). The reset fails, but the fact that the
      IOP_RESET_ALWAYS command was issued has put the card in a purposeful
      shutdown state in preparation for the alternate hardware reset to be
      applied. Yuck.
      
      IOP_RESET is ignored in internal production cards, typically to ensure
      that we catch all adapter lockup issues without the driver progressing
      further, so this would not appear to be a field issue and thus this
      patch was destined to be only in the internal Adaptec source tree.
      IOP_RESET_ALWAYS is reserved for
      kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as
      expected in any case. Also in the past we have had OEMs specifically
      request that cards not be resetable after a BlinkLED/FirmwareAssert for
      one reason or another and To head off the possibility that the Sunrise
      Lake based cards would suffer a similar fate, we propose the enclosed
      fix.
      
      Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when
      he reported an issue to the linux kernel list back in May regarding a
      kexec problem resulting from this reset being ignore. His fix was to
      update the Firmware to one that did not ignore the IOP_RESET. Previous
      kernels did not attempt to reset the adapter and that is why it surfaced
      as a regression in his hands.

      [SCSI] aacraid: add SCSI SYNCHONIZE_CACHE range checking · b90f90d2
      Salyzyn, Mark 提交于
      Customer running an application that issues SYNCHRONIZE_CACHE calls
      directly noticed the broad stroke of the current implementation in the
      aacraid driver resulting in multiple applications feeding I/O to the
      storage causing the issuing application to stall for long periods of
      time. By only waiting for the current WRITE commands, rather than all
      commands, to complete; and those that are in range of the
      SYNCHRONIZE_CACHE call that would associate more tightly with the
      issuing application before telling the Firmware to flush it's dirty
