      Documentation: remove references to /etc/modprobe.conf · 970e2486
      Lucas De Marchi authored
      Usage of /etc/modprobe.conf file was deprecated by module-init-tools and
      is no longer parsed by new kmod tool. References to this file are
      replaced in Documentation, comments and Kconfig according to the
      context.
      
      There are also some references to the old /etc/modules.conf from 2.4
      kernels that are being removed.

      Documentation: mention scripts/diffconfig tool · 673d29f9
      Javi Merino authored
      The kconfig documentation suggests using plain 'diff' to compare config
      files and then adds "Yes, we need something better here".  Commit
      a717417e ("kconfig: add diffconfig utility") added what that comment
      was looking for.

      Pull urgent cgroup fix from Tejun Heo:
       "Commit 61d1d219 ('cgroup: remove extra calls to
        find_existing_css_set') which was part of the rc1 cgroup pull request
        made writes to the cgroup "tasks" file return an uninitialized retval
        on success which can cause boot failures with systemd.
      
        The change stayed in linux-next for quite some time but gcc
        interestingly failed to emit warning about using uninitialized
        variable and the problem seems to materialize only for certain build
        combinations (probably depends on register allocation).
      
        It's just missing local variable initialization and the fix is trivial
        & safe.  As the problem is critical when it materializes, I'm
        fast-tracking it.  Also included is Li's email address change in
        MAINTAINERS."

      cgroup: cgroup_attach_task() could return -errno after success · 8f121918
      Tejun Heo authored
      61d1d219 "cgroup: remove extra calls to find_existing_css_set" made
      cgroup_task_migrate() return void.  An unfortunate side effect was
      that cgroup_attach_task() was depending on that function's return
      value to clear its @retval on the success path.  On cgroup mounts
      without any subsystem with ->can_attach() callback,
      cgroup_attach_task() ended up returning @retval without initializing
      it on success.
      
      For some reason, gcc failed to warn about it and it didn't cause
      cgroup_attach_task() to return non-zero value in many cases, probably
      due to difference in register allocation.  When the problem
      materializes, systemd fails to populate /systemd cgroup mount and
      fails to boot.
      
      Fix it by initializing @retval to zero on declaration.

        The only *functional* change and the reason for the x86/x32 dependency
        is the move of is_ia32_task() into <asm/thread_info.h> so that it can
        be used in other code that needs to understand if a system call comes
        from the compat entry point (and therefore uses i386 system call
        numbers) or not.  One intended user for that is the BPF system call
        filter.  Moving it out of <asm/compat.h> means we can define it

      caused this file to break, since it was still relying on the
      device field to be present.  Map it onto dev_name appropriately
      
      Since there are two consumers with the name "reg-userspace-consumer",
      we have to supply the ID as a suffix in the REGULATOR_CONSUMER calls.

      Linus Torvalds authored
      This reverts commit b43d17f3.
      
      Dave Jones reports that it causes lockups on his laptop, and his debug
      output showed a lot of processes hung waiting for page_writeback (or
      more commonly - processes hung waiting for a lock that was held during
      that writeback wait).
      
      The page_writeback hint made Ted suggest that Dave look at this commit,
      and Dave verified that reverting it makes his problems go away.
      
      Ted says:
       "That commit fixes a race which is seen when you write into fallocated
        (and hence uninitialized) disk blocks under *very* heavy memory
        pressure.  Furthermore, although theoretically it could trigger under
        normal direct I/O writes, it only seems to trigger if you are issuing
        a huge number of AIO writes, such that a just-written page can get
        evicted from memory, and then read back into memory, before the
        workqueue has a chance to update the extent tree.
      
        This race has been around for a little over a year, and no one noticed
        until two months ago; it only happens under fairly exotic conditions,
        and in fact even after trying very hard to create a simple repro under
        lab conditions, we could only reproduce the problem and confirm the
        fix on production servers running MySQL on very fast PCIe-attached
        flash devices.
      
        Given that Dave was able to hit this problem pretty quickly, if we

      This got a fair number of conflicts with the <asm/system.h> split, but
      also with some other sparse-irq and header file include cleanups.  They
      all looked pretty trivial, though.

      Merge branch 'for-3.4' of git://linux-nfs.org/~bfields/linux · 71db34fc
      Linus Torvalds authored
      Pull nfsd changes from Bruce Fields:
      
      Highlights:
       - Benny Halevy and Tigran Mkrtchyan implemented some more 4.1 features,
         moving us closer to a complete 4.1 implementation.
       - Bernd Schubert fixed a long-standing problem with readdir cookies on
         ext2/3/4.
       - Jeff Layton performed a long-overdue overhaul of the server reboot
         recovery code which will allow us to deprecate the current code (a
         rather unusual user of the vfs), and give us some needed flexibility
         for further improvements.
       - Like the client, we now support numeric uid's and gid's in the
         auth_sys case, allowing easier upgrades from NFSv2/v3 to v4.x.
      
      Plus miscellaneous bugfixes and cleanup.
      
      Thanks to everyone!
      
      There are also some delegation fixes waiting on vfs review that I
      suppose will have to wait for 3.5.  With that done I think we'll finally
      turn off the "EXPERIMENTAL" dependency for v4 (though that's mostly
      symbolic as it's been on by default in distro's for a while).
      
      And the list of 4.1 todo's should be achievable for 3.5 as well:
      
         http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues
      
      though we may still want a bit more experience with it before turning it
      on by default.
      
      * 'for-3.4' of git://linux-nfs.org/~bfields/linux: (55 commits)

      Right now we don't seem to need any actual contents for the

      xchg() and cmpxchg() to this new header file for a future patch.
