      udf: Avoid IO in udf_clear_inode · 2c948b3f
      Jan Kara authored
      It is not very good to do IO in udf_clear_inode. First, VFS does not really
      expect inode to become dirty there and thus we have to write it ourselves,
      second, memory reclaim gets blocked waiting for IO when it does not really
      expect it, third, the IO pattern (e.g. on umount) resulting from writes in
      udf_clear_inode is bad and it slows down writing a lot.
      
      The reason why UDF needed to do IO in udf_clear_inode is that UDF standard
      mandates extent length to exactly match inode size. But when we allocate
      extents to a file or directory, we don't really know what exactly the final
      file size will be and thus temporarily set it to block boundary and later
      truncate it to exact length in udf_clear_inode. Now, this is changed to
      truncate to final file size in udf_release_file for regular files. For
      directories and symlinks, we do the truncation at the moment when learn
      what the final file size will be.

      udf: Try harder when looking for VAT inode · e971b0b9
      Jan Kara authored
      Some disks do not contain VAT inode in the last recorded block as required
      by the standard but a few blocks earlier (or the number of recorded blocks
      is wrong). So look for the VAT inode a bit before the end of the media.

      PCI: Global variable decls must match the defs in section attributes · 491424c0
      David Howells authored
      Global variable declarations must match the definitions in section attributes
      as the compiler is at liberty to vary the method it uses to access a variable,
      depending on the section it is in.
      
      When building the FRV arch, I now see:
      
        drivers/built-in.o: In function `pci_apply_final_quirks':
        drivers/pci/quirks.c:2606: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.o

      because the declaration of pci_dfl_cache_line_size in linux/pci.h does not
      match the definition in drivers/pci/pci.c.

      x86, mce: Thermal monitoring depends on APIC being enabled · 485a2e19
      Cyrill Gorcunov authored
      Add check if APIC is not disabled since thermal
      monitoring depends on it. As only apic gets disabled
      we should not try to install "thermal monitor" vector,
      print out that thermal monitoring is enabled and etc...
      
      Note that "Intel Correct Machine Check Interrupts" already
      has such a check.
      
      Also I decided to not add cpu_has_apic check into
      mcheck_intel_therm_init since even if it'll call apic_read on
      disabled apic -- it's safe here and allow us to save a few code
      bytes.

      Here, tvec->tv_usec is "unsigned int" not "unsigned long".
      
      Since the type is different on every platform, it's probably
      best to just use long printf formats and cast.

      x86: Gart: fix breakage due to IOMMU initialization cleanup · f3eee542
      Yinghai Lu authored
      This fixes the following breakage of the commit
      75f1cdf1:
      
      - GART systems that don't AGP with broken BIOS and more than 4GB
        memory are forced to use swiotlb. They can allocate aperture by
        hand and use GART.
      
      - GART systems without GAP must disable GART on shutdown.
      
      - swiotlb usage is forced by the boot option,
        gart_iommu_hole_init() is not called, so we disable GART
        early_gart_iommu_check().

      x86: Move swiotlb initialization before dma32_free_bootmem · f4780ca0
      FUJITA Tomonori authored
      The commit 75f1cdf1 introduced a
      bug that we initialize SWIOTLB right after dma32_free_bootmem so
      we wrongly steal memory area allocated for GART with broken BIOS
      earlier.
      
      This moves swiotlb initialization before dma32_free_bootmem().

      x86: Remove usedac in feature-removal-schedule.txt · 06f8bda8
      FUJITA Tomonori authored
      The reason of removal, "replaced by allowdac and no dac
      combination" is incorrect. There is no way to do the same thing
      with "allowdac" and "nodac" combination.
      
      The usedac option enables us to stop via_no_dac() setting
      forbid_dac to 1. That is, someone who uses VIA bridges can use
      DAC with this option even if some of VIA bridges seem to be
      broken about DAC.

      perf bench: Add "all" pseudo subsystem and "all" pseudo suite · 2044279d
      Hitoshi Mitake authored
      This patch adds a new "all" pseudo subsystem and an "all" pseudo
      suite. These are for testing all subsystem and its all suite, or
      all suite of one subsystem.
      
      (This patch also contains a few trivial comment fixes for
      bench/* and output style fixes. I judged that there are no
      necessity to make them into individual patch.)
      
      Example of use:
      
      | % ./perf bench sched all                      # Test all suites of sched subsystem
      | # Running sched/messaging benchmark...
      | # 20 sender and receiver processes per group
      | # 10 groups == 400 processes run
      |
      |      Total time: 0.414 [sec]
      |
      | # Running sched/pipe benchmark...
      | # Extecuted 1000000 pipe operations between two tasks
      |
      |      Total time: 10.999 [sec]

      | % ./perf bench all                            # Test all suites of all subsystems
      | # Running sched/messaging benchmark...

      Microblaze version 7.20.d is the first MB version which can be run
      on MMU linux. Please do not used previous version because they contain
      HW bug.
      Based on WB support was necessary to redesign whole cache design.
      Microblaze versions from 7.20.a don't need to disable IRQ and cache
      before working with them that's why there are special structures for it.
