      [PATCH] v4l: use saa7111 i2c module in V4L MXB driver · 43b6594e
      Andrew Morton authored
      From: Michael Hunold <hunold@convergence.de>
      
      The attached patch changes my "Multimedia eXtension Board" (MXB)
      Video4Linux-driver to use the standard saa7111 video decoder infrastructure
      (to which I recently submitted changes through Ronald Bultje) instead of
      some home-brewn direct-access stuff.
      
      Nothing serious, but it removes code duplication and makes the code use the
      video decoder api.

      [PATCH] initramfs uncpio fix · 385b866c
      Andrew Morton authored
      From: <viro@parcelfarce.linux.theplanet.co.uk>
      
      init/initramfs.c::do_skip() has an off-by-one that leads to unpacking
      failures for some gzipped cpio images.  We have
      
      static int __init do_skip(void)
      {
              if (this_header + count <= next_header) {
                      eat(count);
                      return 1;
              } else {
                      eat(next_header - this_header);
                      state = next_state;
                      return 0;
              }
      }
      
      and that <= should actually be <.  It almost never matters, since if we hit
      the boundary case (header ending exactly on the gunzip window end) the
      current variant will simply end up doing extra call of do_skip() when we
      get to the next window and that will finish the work (assign state).  The
      only exception is when we hit that in the last window.  That is, if there's
      nothing after the final header (trailer).  Then we miss the final state
      transition (Skip -> Reset) and get "junk in archive" panic.  Normally
      cpio(1) pads the image to multiple of 512, so we actually have a bunch of
      zeroes after the trailer.  And that almost always saves our butts - trailer
      is followed by zeroes, so we get to Reset state just fine.
      
      So we never see that on small in-kernel image (it's less than 512 bytes, so
      it gets a lot of padding) and we almost never see that on external ones
      (1:127 odds of hitting the bug).

      swsusp contained rather nasty bug where it killed machine when intel-agp or
      anything else split kernel 4MB mapping.  Herbert Xu diagnosed this.  Fixed by
      switching to "known good" mapping for during suspend/resume.

      [PATCH] matroxfb: Add support for mapping CRTC<->outputs at boot time · d14672aa
      Andrew Morton authored
      Signed-off-by: default avatarPetr Vandrovec <vandrove@vc.cvut.cz>
      
      Some people expressed interest in having possibility to set CRTC <->
      outputs mapping at boot time, without having to use 'matroxset' later after
      kernel boots.
      
      This patch adds option 'video=matroxfb:outputs:XYZ', where X sets which
      CRTC will connect to primary output, Y sets secondary output and Z sets DVI
      output.
      
      In addition to that I also added missing memset() into maven, which was
      broken since i2c was kobjectified.

      [PATCH] Fix race condition with current->group_info · 8e56790b
      Andrew Morton authored
      From: Olaf Kirch <okir@suse.de>
      
      I have been chasing a corruption of current->group_info on PPC during NFS
      stress tests.  The problem seems to be that nfsd is messing with its
      group_info quite a bit, while some monitoring processes look at
      /proc/<pid>/status and do a get_group_info/put_group_info without any locking.
      
      This problem can be reproduced on ppc platforms within a few seconds if you
      generate some NFS load and do a "cat /proc/XXX/status" of an nfsd thread in a
      tight loop.
      
      I therefore think changes to current->group_info, and querying it from a
      different process, needs to be protected using the task_lock.
      
      (akpm: task->group_info here is safe against exit() because the task holds a
      ref on group_info which is released in __put_task_struct, and the /proc file
      has a ref on the task_struct).

      From: Ingo Molnar <mingo@elte.hu>
      
      printk currently does
      
      	if (oops_in_progres)
      		bust_printk_locks();
      
      which means that once we oops, the printk locking is 100% ineffective and
      multiple CPUs make an unreadable mess on a serial console.  It's a significant
      development hassle.
      
      Fix that up by only popping locks once per ten seconds.
      
      akpm@osdl.org did:
      
        - Bump the timeout to 30 seconds - 9600 baud is slow.
      
        - Handle jiffy wraps: change the logic so that we only skip the lockbust
          if the current time is within 30 seconds of the previous lockbusting
          attempt.

      [PATCH] Prevent scary warnings from knfsd · ed8d9961
      Andrew Morton authored
      From: "J. Bruce Fields" <bfields@fieldses.org>
      
      The kernel currently prints:
      
       nfsd: nobody listening for auth.unix.ip upcall; has some daemon not been started?
      
      on every bootup, during initscripts.
      
      Neil Brown <neilb@cse.unsw.edu.au> says:
      
        It was part of the recent set of idmapper patches.  Bruce wanted the admin
        to get a warning when the idmapper daemon wasn't running.  I thought the
        same warning should apply to any daemon that responded to upcalls.
      
        In the case of auth.unix.ip it isn't strictly necessary for a daemon to be
        running (for comparability with 2.4).
      
        You can get rid of the warning by doing:
      
          mount -t nfsd nfsd /proc/fs/nfs
      
        before mountd is started (init scripts should start doing this I hope, but
        distributions don't tend to use the init script from nfs-utils, so it is
        hard to push it).  This will trigger mountd to listen on auth.unix.ip and
        others.
      
      
      That's a hassle, so Bruce's patch limits the warning purely to the new
      idmapper cache.  It provides a callback in the cache_detail that individual
      caches can use to log messages when upcalls fail because a userspace daemon
      not running.  Implement this method for the idmapping caches.

      [PATCH] ppc64: avoid bogus real IRQ numbers · a5d436c4
      Andrew Morton authored
      Signed-off-by: default avatarPaul Mackerras <paulus@samba.org>
      
      Early in the boot process on pSeries machines, we look in the Open Firmware
      device tree for information about the interrupt assignments, and assign
      virtual IRQ numbers for each physical IRQ.  There is currently a couple of
      bugs in this code which result in us assigning virtual IRQs for nonexistent
      physical IRQs.  This causes problems when we call the firmware to enable or
      disable those nonexistent physical IRQs.  Some versions at least of the
      firmware will hit an assertion failure and crash the machine when this
      happens.
      
      This patch fixes the bugs and ensures that we don't try and use nonexistent
      physical IRQ numbers.  One bug was that we were mapping ISA interrupts,
      which is unnecessary since virtual IRQ numbers 0 - 15 are reserved for
      them.  The other was that when we had a PCI interrupt (which is always in
      the range 1 to 4, corresponding to INTA to INTD) which didn't have a
      mapping in the PCI host bridge above it, we were just using the original
      number (usually 1) rather than ignoring it.

      [PATCH] dynamic addition of virtual disks on PPC64 iSeries · b086c8a3
      Andrew Morton authored
      From: Stephen Rothwell <sfr@canb.auug.org.au>
      
      This patch allows us to dynamically add virtual disks to an iSeries partition.
       It works like this: after you have created the virtual disk file on OS/400
      and attached it to the Linux partition, you need to write to
      /sys/bus/vio/drivers/viodasd/probe (it doesn't matter what you write).  This
      will do the probe.  It calls add_disk() for each new disk, so we get hotplug
      events as a side effect.
      
      This was the nicest way I could think of doing this as the interface to the
      hypervisor is polled ...
