      Adds a better audit for floppy_init().  Fixes one real bug (in calling
      blk_queue_max_sectors()).

      [PATCH] Remove old sh-sci driver · ff60dd36
      Andrew Morton authored
      From: Paul Mundt <lethal@linux-sh.org>
      
      The old drivers/char sh-sci driver is no long used by anyone, both sh and
      h8300 are using the drivers/serial version at this point, so we can get rid
      of the old one entirely.

      *** Warning: "memcmp" [drivers/atm/zatm.ko] undefined!
      
      gcc 3.4 specific problem.  This patch should fix it.  Actually it would be
      better to move all these EXPORT_SYMBOLs into lib/string.c, it is silly that
      each arch has to duplicate all that.

      [PATCH] remove driver model code in mwave driver · 63ad39dc
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      Someone blindly added sysfs support to the driver long time ago without
      understanding the implications (and if they were understood the driver
      would need half a rewrite for it).  Herber Xu recently noticed the problems
      this causes on unload, so let's if 0 out all that code and get the driver
      working again.

      [PATCH] Make /proc/sysrq-trigger ignore sysrq_enabled · dd3871ec
      Andrew Morton authored
      It's silly that writing to /proc/sysrq-trigger does nothing if you haven't
      enabled /proc/sys/kernel/sysrq.  So provide a new __handle_sysrq() which
      ignores the sysrq_enabled check.
      
      The patch also withdraws __handle_sysrq_nolock() from the kernel API.  It had
      no callers.

      [PATCH] Fix endianess in modpost when cross-compiling for sparc on i386 · 42f0e8f2
      Andrew Morton authored
      From: Mathieu Chouquet-Stringer <mchouque@online.fr>
      
      This patch makes the following code work again:
      
      #ifdef STT_REGISTER
                      if (info->hdr->e_machine == EM_SPARC ||
                          info->hdr->e_machine == EM_SPARCV9) {
                              /* Ignore register directives. */
                              if (ELF_ST_TYPE(sym->st_info) == STT_REGISTER)
                                      break;
                      }
      #endif
      
      This portion of code is sparc specific and nothing else in modpost.c uses
      e_machine meaning cross-compiling for sparc on i386 (or any little endian
      machine) is the only way to experience the bug.
      
      Without it, e_machine has the wrong value and modpost then generates a lot
      of "*** Warning: \"symbol\" [filename.ko] undefined" messages.

      [PATCH] implement print_modules() · 22e1c5c4
      Andrew Morton authored
      From: Arjan van de Ven <arjanv@redhat.com>,
            Rusty Russell <rusty@rustcorp.com.au>
      
      The patch below resolves the "Not Yet Implemented" print_modules() thing.
      This is a really useful feature for distros; it allows us to do statistical
      analysis on which modules are present how often in oopses compared to how
      often they are used normally.  In addition it helps to spot candidates for
      certain bugs without having to go back to the customer asking for this
      information.

      [PATCH] fix block layer ioctl bug · deb2ae4a
      Andrew Morton authored
      From: Alan Cox <alan@redhat.com>
      
      The block layer checks for -EINVAL from block layer driver ioctls.  This is
      wrong - ENOTTY is unknown and some drivers correctly use this.  I suspect
      for an internal ioctl 2.7 should change to -ENOIOCTLCMD and bitch about old
      style returns
      
      This is conservative fix for the 2.6 case, it keeps the bogus -EINVAL to
      avoid breaking stuff

      [PATCH] calculate NGROUPS_PER_BLOCK from PAGE_SIZE · 7dd692fc
      Andrew Morton authored
      From: Greg Edwards <edwardsg@sgi.com>
      
      On ia64, EXEC_PAGESIZE (max page size) is 65536, but the default page size is
      16k.  This results in NGROUPS_PER_BLOCK in include/linux/sched.h being
      calculated incorrectly when the page size is anything other than 64k.  For
      example, on a 16k page size kernel, a setgroups() call with a gidsetsize of
      65536 will end up walking over memory since only 1/4 of the needed pages were
      allocated for the blocks[] array in the group_info struct.
      
      Patch below calculates NGROUPS_PER_BLOCK from PAGE_SIZE instead.

      [PATCH] Update laptop mode control script with XFS_HZ=100 · 19bee149
      Andrew Morton authored
      From: Bart Samwel <bart@samwel.tk>
      
      The laptop mode control script incorrectly guesses XFS_HZ=1000.  This is
      incorrect, since the patches that made XFS use USER_HZ went into 2.6.6 as
      well.  This changes XFS_HZ to 100 and removes the warning from the doc about
      checking XFS_HZ.

      [PATCH] expose backing dev max read-ahead · a50376bd
      Andrew Morton authored
      From: Jens Axboe <axboe@suse.de>
      
      Expose the blockdev's VM readahead in /sys/block/hda/queue/read_ahead_kbytes
      
      This duplicates `blockdev --setra', but we're trying to get away from
      ioctls.
      
      It would be nice to have a readahead-setting mechanism which also allows,
      say, NFS to be tuned.  But there is no common exposure point for
      backing_dev_infos.  One option might be per-superblock:
      
      	mount -o remount,read_ahead_kbytes=64
      
      but the generic remount code also has no visibility of the backing_dev, so it
      would need a new super_block operation.  One which doesn't accidentally modify
      default_backing_dev_info.

      From: Arjan van de Ven <arjanv@redhat.com>
      
      the patch below adds a "make buildcheck" target which checks for the "uses
      exit in init" bug using Keith Owen's script.  In the future other similar
      sanity checks can be added to this target, but even just this one has been
      quite useful already.  I use it in the kernel rpm build process for
      example, and I'm sure the OSDL build testers can/want to use it too.

      [PATCH] show last kernel-image symbol in /proc/kallsyms · bfb288f1
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      The current code doesn't show the last symbol (usually _einittext) in
      /proc/kallsyms.  The reason for this is subtle: s_start() returns an empty
      string for position 0 (ignored by s_show()), and s_next() returns the first
      symbol for position 1.
      
      What should happen is that update_iter() for position 0 should fill in the
      first symbol.  Unfortunately, the get_ksymbol_core() fills in the symbol
      information, *and* updates the iterator: we have to split these functions,
      which we do by making it return the length of the name offset.
      
      Then we can call get_ksymbol_core() without moving the iterator, meaning
      that we can call it at position 0 (ie.  s_start()).
