      [SERIAL] Remove base_baud default from 8250_pci · abec7137
      Russell King authored
      Since all boards specify base_baud, the code to default base_baud to
      the architecture-defined BASE_BAUD is redundant.  Also, defaulting
      to the architecture-defined BASE_BAUD is wrong since the UARTs on a
      serial PCI card will be clocked at the same rate no matter what the
      architecture of the host machine.

      [PATCH] alpha: fix GP-load symbol linkage · 054852c4
      Richard Henderson authored
      From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>
      
      This skips the GP-loading function prologue (two instructions: 8 bytes)
      on BRSGP linkage correctly, fixing an oops on alpha while loading the
      aic7xxx driver.

      A regular "memset()" may be using cache control

      This also fixes a warning.

      [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.

      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

      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.

      [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.

      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.

      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.
