      [PATCH] Fix 2.6.0's broken documentation references · 56d7e6f4
      Andrew Morton authored
      From: Hans Ulrich Niedermann <linux-kernel@n-dimensional.de>
      
      I've noted that 2.6.0 contains broken references to documentation.
      
      I got sufficiently annoyed chasing doc files in the wrong place
      that I wrote a script to check the references to documentation
      files.
      
      Some documentation files have moved (e.g.  Documentation/modules.txt to
      Documentation/kbuild/modules.txt).  I adapted the references with a script.

      [PATCH] reiserfs_rename ctime update · 4e2e30bb
      Andrew Morton authored
      From: Nikita Danilov <Nikita@Namesys.COM>
      
      This patches reiserfs_rename.  It adds ctime update of renamed object.  It
      also fixes calculation of maximal possible transaction size during rename.
      
      Thanks to Alex Adriaanse <alex_a@caltech.edu> for finding this.

      [PATCH] shrink_slab acounts for seeks incorrectly · c3f46561
      Andrew Morton authored
      wli points out that shrink_slab inverts the sense of shrinker->seeks: those
      caches which require more seeks to reestablish an object are shrunk harder.
      That's wrong - they should be shrunk less.
      
      So fix that up, but scaling the result so that the patch is actually a no-op
      at this time, because all caches use DEFAULT_SEEKS (2).

      [PATCH] fix pci_update_resource() / IORESOURCE_UNSET on PPC · e6b1fdb7
      Andrew Morton authored
      From: Harald Welte <laforge@gnumonks.org>
      
      [disclaimer:  This was posted on the linuxppc list before, BenH asked me=20
       to re-post it to lkml]
      
      The prism54 (http://prism54.org) driver for my cardbus adapter works
      with 2.4.x, but not 2.6.x on a Titanium G4 Powerbook IV.
      
      On 2.6.x the error message was
      PCI:0001:02:00.0 Resource 0 [00000000-00001fff] is unassigned
      
      After investigating differences in the PCI code of 2.4.x and 2.6.x, i
      noticed that 2.4.x/arc/ppc/kernel/pci.c:pcibios_update_resource()
      contained a couple of lines that unset the IORESOURCE_UNSET bitflag.
      
      In 2.6.x, this is handled by the generic PCI core in
      drivers/pci/setup-res.c:pci_update_resource() code.  However, the code
      is missing the 'res->flags &=3D ~IORESOURCE_UNSET' part.
      
      The below fix re-adds that section from 2.4.x.=20
      
      I'm not sure wether this belongs into the arch-independent PCI api.
      Anyway, on PPC it seems to be needed for certain cardbus devices.
      
      Any comments welcome.

      [PATCH] (workaround): avoid raid1 crash during resync with qlogic controllers · 61179b28
      Andrew Morton authored
      qlogic's 16k maximum I/O size bites again.  Neil says:
      
       The problems we fixed were all to do with normal IO.  This one is resync
       IO.
      
       The problem here is that raid1 always does resync in RESYNC_BLOCK_SIZE
       (=64k) IOs and if the device doesn't cope - tough.
      
       The simple fix is to #define RESYNC_BLOCK_SIZE to PAGE_SIZE in md/raid1.c
      
       The better fix is to rewrite the raid1 resync code to use bio_add_page.
      
       This means we have to build the read request and the write requests at the
       same time, and then when a bio_add_page fails, we back-out the last page
       from the bios that have one too many, and then do the read followed by the
       writes.
      
       I have some code the nearly does this, but I haven't got it actually
       working yet and I am on leave until mid January.
      
       I would recommend doing
      
       fs/drivers/md/raid1.c:
       -#define RESYNC_BLOCK_SIZE (64*1024)
       +#define RESYNC_BLOCK_SIZE PAGE_SIZE
      
       for now.

      [PATCH] Remove iso9660 check for sbsector < 660Mb · 88351d38
      Andrew Morton authored
      From: Jon Burgess <mplayer@jburgess.uklinux.net>
      
      The iso9660 filesystem code checks that the "sbsector" option is
      positioned within the first 660Mb of the disk.
      
      Today the iso9660 filesystem is used on DVD's which are much bigger than
      660Mb and this check prevents the sbsector option being used to specify 
      the location of the superblock of multisession DVD's.
      
      With this check removed I can mount the second session on a DVD-R by 
      specifying the sbsector, even though the  firmware on that drive returns
      bogus data for the TOC.
      
      If an invalid large sector number is entered then a "request beyond end 
      of device" error is reported elsewhere in the block code, but appears to
      do no damage.

      [PATCH] hugepage pagetable freeing fix · eb372d22
      Andrew Morton authored
      From: "Seth, Rohit" <rohit.seth@intel.com>
      
      We recently covered a bug in mm/mmap.c on IA-64.  While unmapping a address
      space, unmap_region calls free_pgtables to possibly free the pages that are
      used for page tables.  Currently no distinction is made between freeing a
      region that is mapped by normal pages vs the pages that are mapped by
      hugepages.  Architecture specific code needs to handle cases where PTEs
      corresponding to a region that is mapped by hugepages is properly getting
      unmapped.  Attached please find a patch that makes the required changes in
      generic part of kernel.  We will need to send a separate IA-64 patch to use
      this new semantics.  Currently, so not to disturb the PPC (as that is the
      only arch that had ARCH_HAS_HUGEPAGE_ONLY_RANGE defined) we are mapping back
      the definition of new function hugetlb_free_pgtables to free_pgtables.

      [PATCH] Fix another dm and bio problem · 655da9eb
      Andrew Morton authored
      From: Mark Haverkamp <markh@osdl.org>
      
      This fixes a problem similar to the patch I submitted on 11/20
      
      http://marc.theaimsgroup.com/?l=linux-kernel&m=106936439707962&w=2
      
      In this case, though, the result is an:
      
      "Incorrect number of segments after building list" message.
      
      The macro __BVEC_START assumes a bi_idx of zero when the dm code can
      submit a bio with a non-zero bi_idx.
      The code has been tested on an 8 way / 8gb OSDL STP machine with a 197G
      lvm volume running dbt2 test.

      [PATCH] change two annoying messages from framebuffer drivers · 0f821f9d
      Andrew Morton authored
      From: Michael Hunold <hunold@convergence.de>
      
      the Linux-on-a-CD system Knoppix has nearly all framebuffer drivers for
      2.4.23 compiled in. Additionally, it surpresses most kernel messages by
      lowering the kernel log level.
      
      Two framebuffer drivers (clgenfb.c and hgafb.c), however, use KERN_ERR
      to say that their particular card has *not* been found which is very
      annoying.
      
      Especially the clgenfb.c driver simply says on bootup:
        >  Couldn't find PCI device
      which can really confuse newbie users.
      
      I've already send a patch that fixes this for 2.4 -- Marcelo and Geert
      Uytterhoeven have already ack'ed it.
      
      The same change should be done for 2.6, too IMHO.
      
      The appended patch replaces two KERN_ERR with KERN_INFO and additionally
      makes the cirrusfb.c message more descriptive.

      [PATCH] Fix memleak on execve failure · 7764b6de
      Andrew Morton authored
      From: IWAMOTO Toshihiro <iwamoto@valinux.co.jp>
      
      I found linux-2.6.0-test11 leaks memory when execve fails.  I've also
      checked the bitkeeper tree and the problem seems to be unchanged.
      
      The attached patch is a partial backout of bitkeeper rev.  1.87 of
      fs/exec.c.  I guess the original change was a simple mistake.
      (free_arg_pages() is a NOP when CONFIG_MMU is defined).

      [PATCH] lib/inflate.c fix · ab49402d
      Andrew Morton authored
      From: "H. Peter Anvin" <hpa@zytor.com>
      
      This patch fixes the "non-terminating inflate" problem that Russell King
      complained about on LKML earlier today.
      
      I chose to use "goto" much like zlib does, in order to not require
      setjmp/longjmp inside the kernel.  It's a bit ugly, but it also lets each
      function chose how it needs to be terminated on error, which is a good
      thing.

      The problem is: even if vfat_striptail_len() counts len of name without

      [PATCH] Put fixmaps into /proc/pid/maps via a pseudo-vma · f9a7b4ad
      Andrew Morton authored
      From: David Mosberger <davidm@napali.hpl.hp.com>
      
      This patch makes /proc/PID/maps report the range from FIXADDR_USER_START to
      FIXADDR_USER_END as a final pseudo-vma.  This is consistent with the notion
      that reading /proc/PID/maps tells you about every page containing data that
      the process can in fact access, and with things such as ptrace allowing
      access to this memory.  Without this, userland tools that want to look at all
      of a process's accessible pages need special-case knowledge about things such
      as the vsyscall DSO page.  With this change, existing code that iterates over
      the /proc/PID/maps lines will cover those pages like any other.  For example,
      this lets gdb's "gcore" command synthesize a core file from a live process
      that contains the vsyscall DSO page as a real core dump would, using its
      existing generic iterator code and no new special cases.

      alltogether under heavy load.  (Specifically Abit KA7/KA7-100).
