      [PATCH] md: Move the test in preferred_minor to where it is used. · 70bb57ee
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      A RAID superblock can indicate which minor number the array should be
      assembled under.  As this is only meaningful when doing auto-start, we move
      the test for it being in the valid range to the place where auto-start
      happens.  When an array is started any other way, it doesn't matter what
      value is here.

      [PATCH] remove_suid() fix · 588d6141
      Andrew Morton authored
      From: viro@parcelfarce.linux.theplanet.co.uk
      
      bernhard_heibler@gmx.de has discovered that NFS is very slow when writing to
      a file which has execute permissions.  See
      
      	http://bugme.osdl.org/show_bug.cgi?id=1936
      
      This patch fixes remove_suid() to not try to modify the inode mode on every
      write to such a file.

      [PATCH] Fix deep stack usage in ncpfs · fea7cfba
      Andrew Morton authored
      From: Petr Vandrovec <vandrove@vc.cvut.cz>
      
      
      Arjan van de Ven pointed out to me there are no checks on name component
      lengths in ncpfs, so potentially 4KB regions could be allocated on stack,
      leading to the user controlled stack overflow.
      
      It was using variable-sized arrays, so this snuck past the static
      stack-usage checking tools.
      
      As NCP is limited to 255 bytes on components, we can simple limit these
      local variables to 256 bytes, and after this stack usage looks more
      acceptable.  Length checking occurs inside ncp_vol2io, during
      iocharset->codepage conversion.
      
      As a side effect support for multibyte codepages now works as it should,
      instead of returning -EINVAL whenever filename in 'codepage' encoding was
      longer than in 'iocharset'.
      
      Other part fixes typo where atime change updated ctime and not atime field.

      [PATCH] initialise cpu_vm_mask in init_mm · 32a0251f
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      Some architectures use cpu_vm_mask to optimise TLB flushes.  On ppc64 we
      are now using a common flush infrastructure that handles both userspace and
      kernelspace (vmalloc) pages.  In order to avoid triggering this
      optimisation we need to mark the init mm as having scheduled on all cpus.
      
      Things currently work by luck (we check for the cpu only having run on the
      local cpu, and the field is initialised to 0), but it would be safer to
      initialise it CPU_MASK_ALL.

      [PATCH] remove valid_addr_bitmap · 73027d99
      Andrew Morton authored
      From: William Lee Irwin III <wli@holomorphy.com>
      
      ->valid_addr_bitmap is initialized nowhere.  Any kern_addr_valid() testing
      it returns 0 unconditionally.
      
      This patch converts kern_addr_valid() implementations using it to return 0
      as per the above and removes it from structures and zone initialization.
      Untested (not even compiletested), though a similar patch also nuking
      d_validate() was in use in -wli for several months.

      [PATCH] fix blockdev --getro for sr, sd, ide-floppy · 2b0bcc8b
      Andrew Morton authored
      From: John McKell <mckellj@iomega.com>
      
      This 2.6.1 patch works by setting gendisk->policy to the correct value
      during initialization as the various drivers decide whether or not the disk
      is writeable.  This patch persuades "blockdev --getro ..." to correctly
      report the read-only state of a newly inserted disk.  This patch applies to
      sr.c, sd.c and ide-floppy.c.  ide-cd.c already has this functionality built
      into it.
      
      Using an Iomega Zip drive as the test case...
      
      Without the patch, I always see:
      
      $ sudo blockdev --getro /dev/sda
      0
      $
      
      That's only correct for writeable disks though.  Only when the patch
      is applied do I see a write-protected disk described correctly:
      
      $ sudo blockdev --getro /dev/sda
      1
      $

      [PATCH] Make naming of parititions in sysfs match /proc/partitions. · 2ae2199f
      Andrew Morton authored
      From: Neil Brown <neilb@cse.unsw.edu.au>
      
      In fs/partitions/check.c  there are two pieces of code that add a
      partition number to a block-device name:
      
        - the 'disk_name' function
        - a snprintf in add_partitions.
      
      'disk_name' inserts a 'p' before the partition number if the device
      name ends with a digit.  The snprintf in add_partitions doesn't.
      
      This patch rectifies this anomoly so that names in sysfs can be
      parsed more reliably.
      
      
      This has been extensively discussed.  It will probably break the external
      `iostat' tool.  But only for disks whose name ends in a digit, which appears
      to be only DAC960.

      [PATCH] vmalloc address offset fix · e5868a37
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      Paul wrote a patch to use some of the rmap infrastructure to flush TLB
      entries on ppc64.  When testing it we found a problem in vmalloc where it
      sets up the pte -> address mapping incorrectly.  We clear the top bits of
      the address but then forget to pass in the full address to
      pte_alloc_kernel.  The end result is the address in page->index is
      truncated.
      
      I fixed it in a similar way to how zeromap_pmd_range etc does it.  I'm
      guessing no one uses the rmap hooks on vmalloc pages yet, so havent seen
      this problem.

      [PATCH] Allow software_suspend to fail · 0c2d1195
      Andrew Morton authored
      From: Pavel Machek <pavel@ucw.cz>
      
      software_suspend() can fail for quite a lot of reasons (for example not
      enough swapspace).  However current interface returned void, so you could
      not propagate error back to userland.  This fixes it.  Plus
      __read_suspend_image() is only done during init time, so we might as well
      mark it __init.

      [PATCH] Trivial cleanups for swsusp · 9db89cf7
      Andrew Morton authored
      From: Pavel Machek <pavel@ucw.cz>
      
      This kills unused part of struct and fixes spelling.
      
      It also fixes codingstyle a bit, converts "can not happen" panic into BUG_ON
      (fill_suspend_header() allocates no memory so panic is meaningless) and adds
      check for sizeof (struct link) [if that is not PAGE_SIZE, we have *bad*
      problem, better check early].

      [PATCH] EDD: read disk80 MBR signature, export through edd module · e100952f
      Andrew Morton authored
      From: Matt Domsch <Matt_Domsch@dell.com>
      
      
      There are 4 bytes in the MSDOS master boot record, at offset 0x1b8,
      which may contain a per-system-unique signature.  By first writing a unique
      signature to each disk in the system, then rebooting, and then reading the
      MBR to get the signature for the boot disk (int13 dev 80h), userspace may
      use it to compare against disks it knows as named /dev/[hs]d[a-z], and thus
      determine which disk is the BIOS boot disk, thus where the /boot, / and
      boot loaders should be placed.
      
      This is useful in the case where the BIOS is not EDD3.0 compliant, thus
      doesn't provide the PCI bus/dev/fn and IDE/SCSI location of the boot disk,
      yet you need to know which disk is the boot disk.  It's most useful in OS
      installers.
      
      This patch retrieves the signature from the disk in setup.S, stores it in a
      space reserved in the empty_zero_page, copies it somewhere safe in setup.c,
      and exports it via /sys/firmware/edd/int13_disk80/mbr_signature in edd.c.
      Code is covered under CONFIG_EDD=[ym].

      [PATCH] add readX_relaxed() interface · 50f33737
      Andrew Morton authored
      From: jbarnes@sgi.com (Jesse Barnes)
      
      Here's the patch to add the new _relaxed variants for PIO read accesses.
      It's been ack'd by gregkh and Grant Grundler, and I think it's ready to
      go.
      
      PCI ordering rules also guarantee that PIO read responses arrive after any
      outstanding DMA writes on that bus, since for some devices the result of a
      readb() call may signal to the driver that a DMA transaction is complete.  In
      many cases, however, the driver may want to indicate that the next readb()
      call has no relation to any previous DMA writes performed by the device.  The
      driver can use the readb_relaxed() for these cases, although only some
      platforms will honor the relaxed semantics.

      [PATCH] bitmap parsing/printing routines, version 4 · 29d82b14
      Andrew Morton authored
      From: Joe Korty <joe.korty@ccur.com>
      
      1) the version in 2.6.1 is broken, doesn't work on 64bit big endian
         machines at all.  This needed fixing.  I thought it best to fix by
         rewriting the printer/parser with an algorithm that is naturally endian &
         sizeof(long) resistant.
      
      2) I wanted all digits to print, eg, 0000ffff,00000004 not ffff,4.
      
      3) I wanted exactly NR_CPUS bits to print (or whatever the bitmap size is
         in bits, and not have what is displayed rounded up to the nearest full
         byte, as the current version did.
      
      4) The bitmap printer and parser should be part of bitmap.[ch] with syntax
         and semantics to match.  The original lib/mask.c versions did not
         recognize this commonality.
