      [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.

            Michal Rokos <m.rokos@sh.cvut.cz>
      
      The problem is: even if vfat_striptail_len() counts len of name without
      trailing dots and sets len to the correct value, utf8_mbstowcs() doesn't
      care about len and takes whole name.  So dirs and files with dots can be
      created on vfat fs.

      [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.

      [PATCH] Fix Summit EBDA parsing · 2dd851e3

      From: Matthew Dobson <colpatch@us.ibm.com>
      
      The code to parse the EBDA (Extended BIOS Data Area) for Summit boxen is
      broken because it does not handle Lookout boxen (external boxes full of
      additional PCI slots).  This patch cleans up some ugliness in
      arch/i386/kernel/summit.c as well as fixing the code to handle Lookout boxen
      and various other configurations of PCI buses.  Without this, Summit PCI bus
      to node mappings are totally hosed with Lookout boxen attatched.  This patch
      depends upon the GENERICARCH fix.

      [PATCH] Add signal state inheritance control to SELinux · 23644641
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch against 2.6.0 adds a control to the SELinux module over the
      inheritance of signal-related state upon security context transitions in
      order to protect the new security context.  If the permission is not
      granted by the policy for a given pair of contexts, then transitions
      between them will clear itimers, flush all pending signals, forcibly
      flush signal handlers, and unblock all signals.  Roland McGrath provided
      input and feedback on the patch. 
      Please apply, or let James Morris and me know if you'd like this to be
      resubmitted later.  Thanks.

      [PATCH] Remove use of nameidata by selinux_inode_permission · e606758e
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch removes the use of nameidata by selinux_inode_permission, as this
      appears to be unsafe in certain cases (e.g.  path_walk call from
      rpc_lookup_parent), leading to an Oops if d_path is subsequently called by
      avc_audit on the (mnt,dentry) pair to generate a pathname for an audit
      message.
      
      The change does not affect the ability of SELinux to perform its permission
      check (which only requires the inode), only the set of information that is
      available for audit messages.  We'll investigate better approaches for the
      SELinux audit generation in the future.

      The dvb-ttpci/av7110 driver needs the firmware_class stuff to work now.
      
      IMHO the appropriate fix is to let the driver automatically select the
