      [PATCH] pdc202xx_old.c: sanitize 66MHz clock use · f154cb92
      Bartlomiej Zolnierkiewicz authored
      Sanitize 66MHz clock use: "enable" 66MHz clock before starting UDMA3/4/5
      read/write transfer and "disable" it after finishing transfer.
      
      - fixes timings for non-UDMA3/4/5 operations (correct 33MHz timings are used)
      
      - allows using UDMA3/4/5 modes on a capable drive even if non-UDMA3/4/5 drive
        is present on the same channel
      
      - fixes corner case when one drive on the channel was using UDMA66/100 + LBA48
        (so clock was enabled/disabled for each read/write) and other one was using
        UDMA66/100 + LBA28, it could happen that request on LBA48 drive disabled
        66MHz clock and it was not enabled for the next transfer on LBA28 drive

      drive->id is now always present even if no device is attached,
      therefore check for drive->present instead.

      [PATCH] pdc202xx_old.c: fix PIO autotuning · 4a59db4e
      Bartlomiej Zolnierkiewicz authored
      This fixes bugzilla bug #1431.
      
      Always tune controller PIO timings.  This fixes lockup during PIO access
      (ie. 'cat /proc/ide/hda/identify') when Promise BIOS is disabled.

      [PATCH] reiserfs v3 should throttle writers · f69c2d56
      Andrew Morton authored
      From: Chris Mason <mason@suse.com>
      
      The v3 reiserfs_file_write func doesn't do any write throttling, which
      leads to a variety of problems.  Here's a patch that makes
      reiserfs_file_write call balance_dirty_pages_ratelimited, and exports that
      func for module usage.

      [PATCH] ALI M1533 audio hang fix · 22d73219
      Andrew Morton authored
      From: risto.sandvik@helsinki.fi
      
      Everything freezes when trying to play sounds using the alsa driver opl3sa2
      (kernel supplied or 1.0.0rc2) on an Acer Extensa series laptop with the Ali
      M1533 PCI to ISA bridge.  Problem exists both in the 2.6 and 2.4 series of
      kernels.
      
      Adding AL_M1533 to drivers/pci/quirks.c fixes the problem for both.  This has
      been a known problem since 2.2.x (see
      http://www.mfn.unipmn.it/~sitta/linux503.html)

      Here's a patch to improve the AFS linux support. It:
      
       (1) Includes Pete's patch to skip the colon in the volume name, compile
           directly into the kernel, and not try to access non-existent caching
           routines.
      
       (2) Changes if (...) BUG() to BUG_ON()
      
       (3) Gets rid of typedefs.
      
       (4) Changes list_for_each() into list_for_each_entry().
      
       (5) Adds more whitespace and wraps lines to please the CodingStyle sticklers.

      Andrew Morton authored

      Within the body of this macro we are accessing rq->bio, but `bio' is an arg
      to the macro.  If someone uses this macro with some variable which is not
      named `bio' it won't compile.
      
      So use a more-likely-to-be-unique identifier for the macro.

      [PATCH] ppc cond_syscall fix · efe067fa
      Andrew Morton authored
      From: Matt Mackall <mpm@selenic.com>
      
      Experimenting with trying to use cond_syscall for a few arch-specific
      syscalls, I discovered that it can't actually be used outside the file
      in which sys_ni_syscall is declared because the assembler doesn't feel
      obliged to output the symbol in that case:
      
      weak.c:
      
      #define cond_syscall(x) asm(".weak\t" #x "\n\t.set\t" #x ",sys_ni_syscall");
      cond_syscall(sys_foo);
      
      $ nm weak.o
               U sys_ni_syscall
      
      One arch (PPC) is apparently trying to use cond_syscall this way
      anyway, though it's probably never been actually tested as the above
      test was done on a PPC.
      
      After trying a bunch of tricks to get it to work nicely, I decided
      there are basically two alternatives: make weak versions of
      sys_ni_syscall wherever they're wanted or put the arch-specific
      cond_syscalls in kernel/sys.c where sys_ni_syscall is defined.
      
      The former approach is a bit crufty and doesn't actually do the right
      thing in practice as you'll get multiple copies of sys_ni_syscall in
      your final image.
      
      The latter introduces some slight arch-pollution in sys.c, but as
      arch-specific cond_syscalls aren't all that frequent, it should be
      pretty minor. So here's a patch to move the current offender to sys.c:

      Andrew Morton authored
      From: Roland McGrath <roland@redhat.com>
      
      Julie DeWandel noticed that in the error case where elf_map has failed,
      load_elf_interp will (at the out_close: label) return the `error' variable,
      but that will contain the result of a prior operation and not the error
      number from elf_map.

      [PATCH] Arrange for EFI-related code to be compiled away · ce65cade
      Andrew Morton authored
      From: David Mosberger <davidm@napali.hpl.hp.com>
      
      There is some EFI-related code which is present in the ia64 build but is not

      The patch fiddles with the efi_enabled definition to arrange for
      `efi_enabled' to be constant zero or constant one in those situations where
      this can be guaranteed.

      Currently xfs has a per-bdev (and XFS filesystem uses up to three underlying

      But for that to happen without rewriting half of XFS (and changing layering
      in a way that we don't really want) we need an additional fs-private variable
      in struct block_device.

      [PATCH] Fix statically declare FIXMAPs · eb4f6fb9
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>, me.
      
      Two uses of the FIXADDR_USER_START/END things are problematic:
      
      a) ppc64 wants the FIXADDR area to be at a different location on 32bit and
         64bit tasks.  On 32bit we want it just below 4GB but that gets in the way
         on 64bit.  By putting both right at -(some small amount) we can also use
         some ppc tricks to get there real quickly (single instruction branches).
      
      b) We assume that FIXADDR_USER_START and FIXADDR_USER_END are constants.
         This breaks the UML build.
      
      Fixes:
      
      - Call it all gate. We currently have half the stuff called fixmap and
        the other gate, lets be consistent.
      
      - Create in_gate_area(), get_gate_vma() and use it in both places
      
      - Provide defaults for in_gate_area/get_gate_vma, allowing an arch to
        override it. (I used CONFIG_* but am open to better suggestions here)
      
      - The /proc/pid/maps vma wasnt marked readable but the get_user
        vma was. That sounds suspicious to me, they are now both the same VMA
        and so have the same (read,exec) permissions

      [PATCH] Alpha: make prefetch_spinlock() a no-op on UP · 3ab88352
      Andrew Morton authored
      From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>
      
      When CONFIG_SMP is not set, spinlock_t is an empty structure, so its
      address has arbitrary alignment.
      
      The prefetch instructions with unaligned address don't have visible side
      effects on alphas with SRM console (except performance degradation) - the
      PALcode handles unaligned traps caused by prefetch instructions internally.
      However, on old AlphaBIOS/MILO boxes unaligned prefetch leads to unhandled
      alignment trap and kernel panic.

      [PATCH] fix up CPU detection in p4-clockmod · 7f6060e8
      Andrew Morton authored
      From: Dominik Brodowski <linux@dominikbrodowski.de>
      
      Too many users use the p4-clockmod cpufreq driver instead of the more
      advanced speedstep-centrino, speedstep-ich or even acpi drivers.  All of
      the latter (usually) provide voltage scaling, while the p4-clockmod driver
      only offers a variant of frequency scaling.  So, warn users if they try out
      this driver instead.
      
      Also, instead of using a local copy, use the speedstep_lib infrastructure
      for detecting the processor speed.  Adding the Pentium-M get_frequency
      function to that module only costs about 200 bytes in object size.

      [PATCH] revert lazy readahead · ded29eb1
      Andrew Morton authored
      From: Trond Myklebust <trond.myklebust@fys.uio.no>
      
      The following reversion is what fixes my regression.  That puts the
      sequential read numbers back to the 2.6.0 values of ~140MB/sec (from the
      current 2.6.1 values of 14MB/second)...
      
      We were triggering I/O of the `ahead' when we hit the last page in the
      `current' window.  That's bad because it gives no pipelining at all.
      
      So go back to full pipelining.
      
      It's not at all clear why this change made a 10x difference in NFS
      throughput.
