      [PATCH] SELinux leak fixes · 07c9e4a4
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      I believe that the patch below fixes the legitimate leaks in the SELinux
      code.  In some cases, it rearranges the code (moving the allocation later
      to reduce the need for further cleanup or linking the object into a
      containing structure earlier so that the policydb_destroy will handle it
      upon any subsequent errors).

      [PATCH] asm/softirq.h is dead · b5ec6dea
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      Still three arches keep an unused copy around and quite a few places refer
      to it in comments still.
      
      Two of the two arches also include it in their _ksyms.c file, but given
      that softirq.h only contains macros (which are in hardirq.c as well) that's
      just a leftover as well.

      [PATCH] use "normalized" syntax for lgdt/lidt · a84d3317
      Andrew Morton authored
      From: "Randy.Dunlap" <rddunlap@osdl.org>
      
      Use common (normalized) asm syntax for lidt/lgdt, specifying that the
      operand is an input value instead of output.

      [PATCH] DAC960: remove redundant (and uninitialized) · b7f6576c
      Andrew Morton authored
      From: Dave Olien <dmo@osdl.org>
      
      this patch fixes a bug that appeared only on Alpha hardware with
      DAC960 controllers.  The Command->PciDevice structure member was
      never initialized.  This was passed to the pci scatter/gather functions.
      This didn't cause a problem for x86 platforms because the scatter/gather
      funtions never really used that information.  Alpha platforms do use
      that pointer.
      
      The Command->PciDevice field was also redundant with the Controller->PCIDevice
      field, which IS initialized properly.  So, eliminating the redundant
      structure member and substituting the Controller's member fixes the bug.

      [PATCH] remove CONFIG_SERIAL_21285_OLD · eb73c88b
      Andrew Morton authored
      From: Adrian Bunk <bunk@fs.tum.de>
      
      CONFIG_SERIAL_21285_OLD depends on the non-existent option CONFIG_OBSOLETE,
      IOW it's not selectable, and the help text says "This is obsolete and will
      be removed during later 2.5 development.".

      Yes. Here 2.4 had the terrible code
      
           mode = (inode->i_mode & S_IXGRP)*(S_ISGID/S_IXGRP) | S_ISUID;
      
      while 2.6 does things via notify_change().  However, in 2.6 notify_change()
      does not allow removal of the SUID bit because you are not owner of the
      file :-).  So, we have to convince inode_change_ok() to do it anyway.

      [PATCH] make CONFIG_HUGETLB_PAGE mirror CONFIG_HUGETLBFS · 829d1232
      Andrew Morton authored
      At present you can set CONFIG_HUGETLB_PAGE and not CONFIG_HUGETLBFS, which
      give the kernel low-level hugepage support, but no userspace API with which
      to access it.
      
      And with the recent hugetlbfs-accounting fix, the low-level code needs
      functions which are in hugetlbfs, so CONFIG_HUGETLBFS=n,
      CONFIG_HUGETLB_PAGE=y doesn't even link.
      
      So we flip things around: CONFIG_HUGETLB_PAGE is set if CONFIG_HUGETLBFS is
      set and CONFIG_HUGETLB_PAGE is unset if CONFIG_HUGETLBFS is unset.  The
      CONFIG_HUGETLB_PAGE option hence disappears from the per-arch configuration
      menus.

      [PATCH] Hugetlb FS quota accounting problem · 41cffedc
      Andrew Morton authored
      From: "Chen, Kenneth W" <kenneth.w.chen@intel.com>
      
      We found a problem in hugetlbfs file system quota when using huge page
      via mmap.  The mmap method in hugetlbfs_file_operation always takes
      quota for every mmap even for pages that are already allocated on that
      inode.  This results in taxing the same hugepage multiple times and
      causing mmap to fail on existing file when quota mistakenly runs out.

      [PATCH] switch remaining serial drivers to initcalls · f751e52a
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      All drivers that compile on ppc with CONFIG_ISA set (= all but
      some m68-only drivers), I looked at the compile warnings very
      closely and there are no new warnings or even errors this time :)
      
      drivers/char/Makefile needed to be reordered big time to keep
      the intialization order the same.

      [PATCH] disallow utime{s}() on immutable or append-only files · 905f90fe
      Andrew Morton authored
      From: Ethan Benson <erbenson@alaska.net>
      
      Currently Linux allows the use of the utime() and utimes() syscalls on
      immutable or append-only files, this is incorrect.
      
      utime{s}() is not supposed to work if you lack write access to a file,
      in the case of an immutable file NOBODY has write access.
      
      for an append-only file it only makes sense to be able to update its
      time to present, not the past.
      
      I have checked BSD, and they implement the behavior I propose, for
      immutable files utime() and utimes() fail.  for append-only files they
      fail if the time argument is not NULL.

      [PATCH] add -Wdeclaration-after-statement · 535231e8
      Andrew Morton authored
      From: John Levon <levon@movementarian.org>
      
      Not that many people are going to be using GCC 3.4 currently, but it
      might help a bit to prevent compilation bugs like that just witnessed
      in procfs.
      
      (And it consolidates the check_gcc implementation nicely)

      [PATCH] mark devfs obsolete · 71c53af4
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      Richard hasn't touched it for about a year and since then only bugfixes and
      my changes to the kernel interface went in.  No one has stepped up to
      maintain it and with udev we have a proper replacement now.
      
      I will do some more work before 2.6 (mainly trying to implement Al's
      refcounting scheme to avoid stale entries), but that's it.

      [PATCH] Try harder in IRQ context before falling back to ksoftirqd · e4e9bd23
      Andrew Morton authored
      From: "David S. Miller" <davem@redhat.com>
      
      It's from Ingo Molnar.  ksoftirqd kicks in way too early, so do more work in
      interrupt context before falling back.
      
      We can probably sysctl this thing, that way everyone gets what they want
      probably...
      
      (has been in -mm since 2.5.71 and I haven't heard a peep).
