      Linus Torvalds authored
      This reverts commit bd52276f ("x86-64/efi: Use EFI to deal with
      platform wall clock (again)"), and the two supporting commits:
      
        da5a108d: "x86/kernel: remove tboot 1:1 page table creation code"
      
        185034e7: "x86, efi: 1:1 pagetable mapping for virtual EFI calls")
      
      as they all depend semantically on commit 53b87cf0 ("x86, mm:
      Include the entire kernel memory map in trampoline_pgd") that got
      reverted earlier due to the problems it caused.
      
      This was pointed out by Yinghai Lu, and verified by me on my Macbook Air
      that uses EFI.

      Pull target updates from Nicholas Bellinger:
       "It has been a very busy development cycle this time around in target
        land, with the highlights including:
      
         - Kill struct se_subsystem_dev, in favor of direct se_device usage
           (hch)
         - Simplify reservations code by combining SPC-3 + SCSI-2 support for
           virtual backends only (hch)
         - Simplify ALUA code for virtual only backends, and remove left over
           abstractions (hch)
         - Pass sense_reason_t as return value for I/O submission path (hch)
         - Refactor MODE_SENSE emulation to allow for easier addition of new
           mode pages.  (roland)
         - Add emulation of MODE_SELECT (roland)
         - Fix bug in handling of ExpStatSN wrap-around (steve)
         - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve)
         - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab)
         - Convert ib_srpt to use modern target_submit_cmd caller + drop
           legacy ioctx->kref usage (nab)
         - Convert ib_srpt to use modern target_submit_tmr caller (nab)
         - Add link_magic for fabric allow_link destination target_items for
           symlinks within target_core_fabric_configfs.c code (nab)
         - Allocate pointers in instead of full structs for
           config_group->default_groups (sebastian)
         - Fix 32-bit highmem breakage for FILEIO (sebastian)
      
        All told, hch was able to shave off another ~1K LOC by killing the
        se_subsystem_dev abstraction, along with a number of PR + ALUA
        simplifications.  Also, a nice patch by Roland is the refactoring of
        MODE_SENSE handling, along with the addition of initial MODE_SELECT
        emulation support for virtual backends.
      
        Sebastian found a long-standing issue wrt to allocation of full
        config_group instead of pointers for config_group->default_group[]
        setup in a number of areas, which ends up saving memory with big
        configurations.  He also managed to fix another long-standing BUG wrt
        to broken 32-bit highmem support within the FILEIO backend driver.
      
        Thank you again to everyone who contributed this round!"

      This reverts commit 53b87cf0.
      
      It causes odd bootup problems on x86-64.  Markus Trippelsdorf gets a
      repeatable oops, and I see a non-repeatable oops (or constant stream of
      messages that scroll off too quickly to read) that seems to go away with
      this commit reverted.
      
      So we don't know exactly what is wrong with the commit, but it's
      definitely problematic, and worth reverting sooner rather than later.

      This reverts commit f269ae04.
      
      It turns out it causes a very noticeable interactivity regression with
      CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
      terminal window, while scrolling in a browser - the autogrouping means
      that the two end up in separate cgroups, and the browser should be
      smooth as silk despite the high load).
      
      Says Paul Turner:
       "It seems that the update-throttling on the wake-side is reducing the
        interactive tasks' ability to preempt.  While I suspect the right
        longer term answer here is force these updates only in the
        cross-cgroup case; this is less trivial.  For this release I believe
        the right answer is either going to be a revert or restore the updates
        on the enqueue-side."

        A NACK is probably the right thing. I was mostly converting a few
        other drivers which used some simple, common patterns to use my new
        common code, but this driver was missing it altogether. It looks like
        there may be bigger issues, though, as you point out.

        As noted earlier, I don't have much interest in this driver. I agree
        that there are some other issues with the driver; I think it leaks
        memory if it is ever allowed to unload, for one. Feel free to submit
        an alternative patch to prevent this driver from being built as a
        module.

       "This patch set includes two large new drivers: mpt3sas (for the next
        gen fusion SAS hardware) and csiostor a FCoE offload driver for the
        Chelsio converged network cards (this includes some net changes which
        I've OK'd with DaveM).
      
        The rest of the patch is driver updates (qla2xxx, lpfc, hptiop,
        be2iscsi) plus a few assorted updates and bug fixes.
      
        We also have a Power Management rework in the Upper Layer Drivers

        enabler is still being worked on.

      Merge emailed autofs cleanup/fix patches from Ian Kent

      autofs4 - use simple_empty() for empty directory check · 0259cb02
      Ian Kent authored
      For direct (and offset) mounts, if an automounted mount is manually
      umounted the trigger mount dentry can appear non-empty causing it to
      not trigger mounts. This can also happen if there is a file handle
      leak in a user space automounting application.
      
      This happens because, when a ioctl control file handle is opened
      on the mount, a cursor dentry is created which causes list_empty()
      to see the dentry as non-empty. Since there is a case where listing
      the directory of these dentrys is needed, the use of dcache_dir_*()
      functions for .open() and .release() is needed.
      
      Consequently simple_empty() must be used instead of list_empty()
      when checking for an empty directory.

      autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount · f55fb0c2
      Ian Kent authored
      The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire
      for autofs rootless multi-mount dentrys to prevent unnecessary calls
      to ->d_automount().
      
      Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed()
      is always called so the check can be done in ->d_manage() without the
      need to change the flag. This still avoids unnecessary calls to
      ->d_automount(), adds negligible overhead and eliminates a seriously
      ugly check in the expire code.
