      [PATCH] 3c59x: support for ATI Radeon 9100 IGP · 78d601f9
      Bogdan Costescu authored
      The following patch adds support for the 3Com networking core found in the
      ATI Radeon 9100 IGP southbridge used on boards like Asus P4R800-VM.
      
      The main point of this patch is using HAS_MII instead of HAS_NWAY for the
      definition of the board.  All the previous trials since the end of last
      year used HAS_NWAY which disables the Tx part of the transceiver; using
      HAS_NWAY was the way all 3Com Cyclone and Tornado chips worked, as they had
      the transceiver integrated.  The ATI solution has an external transceiver
      and I had to physically see the different chip on the board (the board was
      provided by ATI) to finally understand that it needs the HAS_MII
      definition...  I'm still waiting for some docs from ATI to clarify if this
      is the correct way of handling this chip and if there are any differences
      w.r.t EEPROM handling, but as it appears to work and was also confirmed by
      other testers, I don't want to keep owners of such boards away from their
      networks :-)
      
      The textual identification was a bit hard to decide; it's called
      "3c920B-EMB-WNM" in the Windows .INF file that Asus provides for their
      boards.  As this name was already used for PCI ID 9210, I added the
      paranthesis which specifies where this chip is found.
      
      The Scyld driver defines FEATURE_TORNADO to include HAS_NWAY.  This board
      would then probably need to not be defined with FEATURE_TORNADO, but the
      same as in this patch.
      
      I would like to publicly thank Tyson Vickers for both ideas and patience
      during the last few weeks.  He managed to get the driver working by
      randomly setting driver parameters :-) But then he contacted me and worked
      with me towards the solution.

      [PATCH] sisfb update 1.7.10 · 3d178e97
      Thomas Winischhofer authored
      attached is an update for the sisfb driver to version 1.7.10.
      
      This update includes
      
      - fixes for pure 64bit and 32/64bit mixed systems (add ioctl conversion;
        fix variable sizes, etc; REQUIRED for current X.org/XFree86 on 64bit
        systems, even if pure 64bit),
      
      - fixes for 301C video bridge, (scales TV output correctly now)
      
      - fixes for 1600x1200 and 1400x1050 LCD panels,
      
      - many fixes for 661/741/760 (amongst others, proper LFB support for the
        760 and corrections for SiS' new BIOS data layout; would lead to display
        corruption with old driver)
      
      - add support for many modes for LCD which were unsupported previously,
      
      - add support for HiVision and YPbPr HDTV
      
      - "vga=" statement now honoured properly (sisfb will set the same mode as
        the kernel did by default)
      
      - use LCD native resolution mode if no mode is given
      
      - a major clean up of main driver code,
      
      - radical removal of duplicate (or nearly duplicate) code,
      
      - switched to 2.6 module_param macros,
      
      - enhanced communication with the X driver,
      
      - added eventual POSTing of SiS300/305 card for non-x86 archs,
      
      - added ability to relocate the image on the TV screen using a userland
        tool,
      
      - added Documentation/fb/sisfb.txt (why the heck was this missing?!)
      
      - small fix for SiS DRM driver (match 32/64bit fixes mentioned above)
        (cast the data passed to sis_free as u32)
      
      - make driver re-entrant by avoiding static structures and variables.
      
      As usual, heavily tested.  The mode switching code is even lab-tested by
      SiS (although 100% written by me).  Please apply asap (especially since
      64bit systems were not properly supported previously; as mentioned, current
      X.org/XFree86 needs this update for proper communication with the
      framebuffer driver on 64bit systems.  X crashes on such systems with the
      old driver).

      [PATCH] iso9660: fix handling of inodes beyond 4GB · 9210c204
      Paul Serice authored
      This is my fourth attempt to patch the isofs code.  It is similar to the last
      posting except this one implements the NFS get_parent() method which has
      always been missing.
      
      The original problem I set out to addresses is that the current iso9660 file
      system cannot reach inodes located beyond the 4GB barrier.  This is caused by
      using the inode number as the byte offset of the inode data.  Being 32-bits
      wide, the inode number is unable to reach inode data that does not reside on
      the first 4GB of the file system.
      
      This causes real problems with "growisofs"
      
            http://fy.chalmers.se/~appro/linux/DVD+RW/#isofs4gb
      
      and my pet project "shunt"
      
            http://www.serice.net/shunt/
      
      This patch switches the isofs code from iget() to iget5_locked() which allows
      extra data to be passed into isofs_read_inode() so that inode data anywhere on
      the disk can be reached.
      
      The inode number scheme was also changed.  Continuing to use the byte offset
      would have resulted in non-unique inodes in many common situations, but
      because the inode number no longer plays any role in reading the meta-data off
      the disk, I was free to set the inode number to some unique characteristic of
      the file.  I have chosen to use the block offset which is also 32-bits wide.
      
      Lastly, the pre-patch code uses the default export_operations to handle
      accessing the file system through NFS.  The problem with this is that the
      default NFS operations assume that iget() works which is no longer the case
      because of the necessity of switching to iget5_locked().  So, I had to
      implement the NFS operations too.  As a bonus, I went ahead and implemented
      the NFS get_parent() method which has always been missing.

      [PATCH] BSD accounting format rework · f38928f4
      Tim Schmielau authored
      BSD accounting format rework:
      
      Use all explicit and implicit padding in struct acct to
      
       - correctly report 32 bit uid/gid,
       - correctly report jobs (e.g., daemons) running longer than 497 days,
       - increase the precision of ac_etime from 2^-13 to 2^-20
         (i.e., from ~6 hours to ~1 min. after a year)
       - store the current AHZ value.
       - allow cross-platform processing of the accounting file
         (limited for m68k which has a different size struct acct).
       - introduce versioning for smooth transition to incompatible formats in
         the future. Currently the following version numbers are defined:
           0: old format (until 2.6.7) with 16 bit uid/gid
           1: extended variant (binary compatible to v0 on M68K)
           2: extended variant (binary compatible to v0 on everything except M68K)
           3: a new binary incompatible format (64 bytes)
           4: new binary incompatible format (128 bytes).
              layout of its first 64 bytes is the same as for v3.
           5: marks second half of new binary incompatible format (128 bytes)
              (layout is not yet defined)
      
      All this is accomplished without breaking binary compatibility.  32 bit
      uid/gid support is compatible with the patch previously floating around and
      used e.g.  by Red Hat.
      
      This patch also introduces a config option for a new, binary incompatible
      "version 3" format that
      
       - is uniform across and properly aligned on all platforms
       - stores pid and ppid
       - uses AHZ==100 on all platforms (allows to report longer times)
      
      Much of the compatibility glue goes away when v1/v2 support is removed from
      the kernel.  Such a patch is at
      
        http://www.physik3.uni-rostock.de/tim/kernel/2.7/acct-cleanup-04.patch
      
      and might be applied in the 2.7 timeframe.
      
      The new v3 format is source compatible with current GNU acct tools (6.3.5).
      However, current GNU acct tools can be compiled for only one format.  As there
      is no way to pass the kernel configuration to userspace, with my patch it will
      still only support the old v2 format.  Only if v1/v2 support is removed from
      the kernel, recompiling GNU acct tools will yield v3 support.
      
      A preliminary take at the corresponding work on cross-platform userspace tools
      (GNU acct package) is at
      
        http://www.physik3.uni-rostock.de/tim/kernel/utils/acct/
      
      This version of the package is able to read any of the v0/v2/v3 formats,
      regardless of byte-order (untested), even within the same file.
      Cross-platform compatibility with m68k (v1 format) is not yet implemented, but
      native use on m68k should work (untested).  pid and ppid are currently only
      shown by the dump-acct utility.
      
      Thanks to Arthur Corliss, Albert Cahalan and Ragnar Kjørstad for their
      comments, and to Albert Cahalan for the u64->IEEE float conversion code.

      [PATCH] Validate PM-Timer rate at boot time · 6d58b128
      Joris van Rantwijk authored
      Add a check to the PM-Timer initialization code.  It validates the PM-Timer
      rate against PIT channel 2 and rejects the PM-Timer if its rate is not
      withing 5% of the expected number.
      
      Rationale:
      
      The PMTMR timers of certain (older) mainboards are running at invalid
      rates, often much faster than the rate expected by the PM-Timer code.  This
      causes the system clock to run much too fast.  See also
      http://bugme.osdl.org/show_bug.cgi?id=2375
      
      Possible workarounds are disabling the PM-Timer in the kernel config or
      disabling the PM-Timer at boot time through the "clock=tsc" parameter.
      However, we believe it is more user friendly to automatically validate the
      PM-Timer rate at boot time before using it as the system time source.
      
      Tested by me (with broken timer) and John Stultz (with good timer) and
      believed to be ok.

      [PATCH] x86: remove io_apic_sync · 2765df29
      Ingo Molnar authored
      The patch below gets rid of io_apic_sync().
      
      io_apic_sync() was introduced in 2.1.104 and it was originally done for
      masking and unmasking as well.  Later the unmasking use got removed but the
      masking use lingered around.  I dont think it was ever justified to do it
      and clearly since the lack of io_apic_sync() didnt break some of the other
      writes we do to the IO-APIC registers, it must be unnecessary in the
      masking case too.

      [PATCH] x86: remove APIC_LOCKUP_DEBUG · ecab0503
      Ingo Molnar authored
      the patch below gets rid of APIC_LOCKUP_DEBUG.  It has been in the kernel
      for more than 3 years and the message was only reported once during that
      period of time - and even in that case it was a side-effect of a really bad
      crash.  The lockup workaround works, the debugging code can be moved out.

      [PATCH] io_apic.c code consolidation · 6be35b97
      Pavel Machek authored
      This cleans up io_apic.c a bit -- I do not really like 4 copies of same
      code.
      
      Ingo said:
      
         yeah, agreed - i checked & test it, it's ok.  I made a small
         modification (see the patch below) to uninline the __modify_IO_APIC_irq()
         function - shaving 0.5K off the kernel's size.

      [PATCH] Fix read() vs truncate race · 4bd9607e
      Nick Piggin authored
      do_generic_mapping_read()
      {
      	isize1 = i_size_read();
      	...
      	readpage
      	copy_to_user up to isize1;
      }
      
      readpage()
      {
      	isize2 = i_size_read();
      	...
      	read blocks
      	...
      	zero-fill all blocks past isize2
      }
      
      If a second thread runs truncate and shrinks i_size, so isize1 and isize2 are
      different, the read can return up to a page of zero-fill that shouldn't really
      exist.
      
      The trick is to read isize1 after doing the readpage.  I realised this is the
      right way to do it without having to change the readpage API.
      
      The patch should not cost any cycles when reading from pagecache.

      [PATCH] invalidate_inodes2(): mark pages not uptodate · 3cf8b87b
      Andrew Morton authored
      Andrea Arcangeli <andrea@suse.de> points out that invalidate_inode_pages2() is
      supposed to mark mapped-into-pagetable pages as not uptodate so that next time
      someone faults the page in we will go get a new version from backing store.
      
      The callers are the direct-io code and the NFS "something changed on the
      server" code.  In both these cases we do need to go and re-read the page.

      [PATCH] Check return status of register calls in i82365 · 8d6d3943
      Herbert Xu authored
      i82365 calls driver_register and platform_device_register without checking
      their return values.  This patch fixes that.
      
      It also runs platform_device_register() prior to isa_probe() so we don't have
      to undo ise_probe()'s effects if platform_device_register() ends up failing.

      [PATCH] small tweaks to standard resource stuff · bc3e9bd2
      Rene Herman authored
      Various small tweaks. Compiled and booted.
      
      1. add IORESOURCE_BUSY | IORESOURCE_MEM also for the kernel code and
           data resources. I don't believe this actually matters one bit, but
           they're hooked into a BUSY/MEM parent ("System RAM") and marking
           them busy seems to make sense.
      
      2. delete the .start = 1M default for the kernel code resource. This
           isn't actually a change; it's set to virt_to_phys(_text) in
           setup_arch() overriding any default anyways.
      
      3. s/vram_resource/video_ram_resource/. Lines up much nicer with
           video_rom_resource...
      
      4. s/checksum/romchecksum/. setup.c is a fairly large file, and
           "checksum" pollutes the namespace.

      H. Peter Anvin authored
      (With Andrew Morton).
      
      The current dynamic pty allocation scheme has a few problems:
      
      - pty numbers grow to be very large, causing wtmp file bloat.
      
      - Seems to break libc5 and some old applications
      
      So change it to do first-fit.  An IDR tree is used to provide a
      logarithmic-time search.

      [PATCH] Ext3: Retry allocation after transaction commit (v2) · 5c4ad014
      Theodore Y. Ts'o authored
      Here is a reworked version of my patch to ext3 to retry certain filesystem
      operations after an ENOSPC error.  The ext3_should_retry_alloc() function will
      not wait on the currently running transaction if there is a currently active
      handle; hence this should avoid deadlocks in the Lustre use case.  The patch
      is versus BK-recent.
      
      I've also included a simple, reliable test case which demonstrates the problem
      this patch is intended to fix.  (Note that BK-recent is not sufficient to
      address this test case, and waiting on the commiting transaction in
      ext3_new_block is also not sufficient.  Been there, tried that, didn't work.
      We need to do the full-bore retry from the top level.  The
      ext3_should_retry_alloc() will only wait on the committing transaction if
      there is an active handle; hence Lustre will probably also need to use
      ext3_should_retry_alloc() if it wants to reliably avoid this particular
      problem.)

      [PATCH] pc9800: merge std_resources.c back into setup.c · 248af7e2
      Rene Herman authored
      std_resources.{c,h} was only split off due to pc9800 wanting to override it.
      With it gone, it might as well be merged back in.  Doesn't change any code.
      It was compiled and booted.
      
      This time this also actually doesn't break compilation of any of the
      subarches.  That's to say, any further.  I guess it might have been my .config
      (my regular PC config, with just the subarch switched through menuconfig) or
      O=, but only ELAN actually compiled.  Voyager and VISWS bombed out at the
      final link and NUMAQ much sooner (with "physnode_map undeclared" during
      compilation of numaq.c).
