      We need to use "memset_io()" when accessing PCI · ed40244e
      Linus Torvalds authored
      mapped memory.
      
      A regular "memset()" may be using cache control
      instructions etc, which is not appropriate for
      memory-mapped IO.
      
      This also fixes a warning.

      [ARM PATCH] 1879/1: fix a few xscale "drain write & fill buffer" instructions · cd594a3b
      Robin Farine authored
      Patch from Robin Farine
      
      Fix the xscale cache handling routines that were invalidating a D 
      cache line instead of draining the write & fill buffer as intended.

      [ARM PATCH] 1883/1: Bit 4 in pmd should be 0 for the ARMv6 architecture · 6ef8f0dc
      Catalin Marinas authored
      Patch from Catalin Marinas
      
      Unlike the v5 architecture, the ARM1136 requires that BIT4 is 0 in
      the first level page descriptor (ARM1136 TRM, page 6-39). It works
      at the moment but it might break future v6 cores.

      [ARM PATCH] 1882/1: Fixes in the v6_dma_(invalidate|flush)_range functions · dc1b0aa3
      Catalin Marinas authored
      Patch from Catalin Marinas
      
      The v6_dma_invalidate_range - the "mcr" instruction for draining
      
      the write buffer requires r0 == 0. A "cmp" instruction for
      
      testing the end address is missing in the v6_dma_flush_range
      
      function.

      [ARM PATCH] 1881/1: Illegal strex instruction generated by gcc · 2b01a2d3
      Catalin Marinas authored
      Patch from Catalin Marinas
      
      The _raw_write_(try)lock functions in include/asm-arm/spinlock.h
      
      should use the early clobber modifier (&) for the "tmp" register.
      
      A newer compiler (gcc-3.4.0) generates an "strexeq %0, %1, [%2]"
      
      instruction where %0 is the same as %2, which is illegal.

      Catalin Marinas authored
      Patch from Catalin Marinas
      
      In the blockops_check() function, cache_type is uninitialised

      [libata] internal cleanups · 50112a63
      Jeff Garzik authored
      Remove unused 'done_late' arg to ata_qc_complete(), which was never
      useful in 2.4, and never used at all in 2.6.
      
      This allows us to eliminate the same arg from ata_dma_complete(),
      and also make it more correct by passing the command rather than
      the ATA port structure as arg0.

      [PATCH] ide-disk.c: more write cache fixes · 7e33820d
      Bartlomiej Zolnierkiewicz authored
      - many Maxtor disks incorrectly claim CACHE FLUSH EXT command support,
        fix it by checking both CACHE FLUSH EXT command and LBA48 support
        (thanks to Eric D. Mudama for help in fixing this)
      
      - write_cache() was called with 'drive->id->cfs_enable_2 & 0x3000' as 'int arg'
        argument which was always truncated to zero due to 'u8 drive->wcache = arg'
        assignment so write cache was indeed enabled but drive->wcache was zero
        (thanks to Rene Herman for help in debugging this)
      
      - flush cache in idedisk_start_power_step() only if ATA-6 CACHE FLUSH (EXT)
        bits are present in disk's identify data (prevents sending unknown commands)
      
      - set drive->wcache in idedisk_setup() not idedisk_attach() (no need to check
        id->command_set_2 - we check id->cfs_enable_2 instead in write_cache() call)
      
      - use ide_cacheflush_p() in idedisk_setup()
      
      - minor cleanups

      [PATCH] Handle empty nodes in sysfs on x86-64 · ab9e69a3
      Andi Kleen authored
      This code is shared between i386 and x86-64, and x86-64 needs to check
      for empty nodes here.  Otherwise you can get oopses at boot in some
      circumstances. 
      
      This handles empty nodes != 0; empty node zero are still broken in other
      ways.

      [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)

      which seems to clobber memory past the end of what it allocated.

      [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.
