      [PATCH] x86-64: fix /dev/mem caching behaviour · f1eda416
      Andi Kleen authored
      This changes the /dev/mem caching behaviour on x86-64 to be compatible
      with i386.
      
      By default everything is set cached.
      
      This actually makes WC MTRRs on AMD systems work, which would get
      overriden by the UC PAT bits that were set earlier.  This can make DVD
      decoding with hardware support a lot faster. 
      
      It also supports O_SYNC now, like i386, although that is not really
      safe, because it allows the user to create undefined cache attribute
      conflicts that can corrupt caches in some circumstances.  I kept it for
      now.  Better would to disallow it, until Terrence Ripperda's PAT
      framework is getting merged, that can avoid these problems. 
      
      Actually it would be probably a good idea to add a printk here to catch
      broken programs for i386 and x86-64, but that is for another patch.

      [PATCH] x86-64 updates · fb75a3d4
      Andi Kleen authored
      Various accumulated x86-64 patches and bug fixes.
      
      It fixes one nasty bug that has been there since NX is used by 
      default in the kernel. With heavy AGP memory allocation it would
      set NX on parts of the kernel mapping in some corner cases, which gave
      endless crash loops. Thanks goes to some wizards in AMD debug labs
      for getting a trace out of this.
      
      Also various other fixes. This patches only changes x86-64 specific
      files, i have some changes outside too that I am sending separately.
      
       - Fix help test for CONFIG_NUMA
       - Don't enable SMT nice on CMP
       - Move HT and MWAIT checks up to generic code
       - Update defconfig
       - Remove duplicated includes (Arthur Othieno)
       - Set up GSI entry for ACPI SCI correctly (from i386)
       - Fix some comments
       - Fix threadinfo printing in oopses
       - Set task alignment to 16 bytes
       - Handle NX bit for code pages correctly in change_page_attr()
       - Use generic nops for non amd specific kernel
       - Add __KERNEL__ checks in unistd.h (David Lee)

      [PATCH] groups_alloc(0) clobbers memory past end of block · a2c47912
      Andrew Morton authored
      From: Olaf Kirch <okir@suse.de>
      
      Authentication code in net/sunrpc makes frequent use of groups_alloc(0),
      which seems to clobber memory past the end of what it allocated.
      
      If called with gidsetsize == 0, groups_alloc will set nblocks = 0,
      but still does a
      
      	group_info->blocks[0] = group_info->small_block;

      [PATCH] Increase xfsbufd_centisecs when in laptop mode · 03e6a21b
      Andrew Morton authored
      From: Bart Samwel <bart@samwel.tk>
      
      The attached patch is the outcome of a discussion with Nathan.
      
      When laptop mode is active, there is no need for XFS to wake up xfsbufd (the
      daemon that flushes buffers that are too old) too often.  The default is once
      every second, this patch makes laptop mode do it once every 30 seconds.

      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.

            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.
