    udf: Avoid IO in udf_clear_inode

    jankara committed Dec 3, 2009
    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

    jankara committed Nov 30, 2009
    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

    David Howells committed with torvalds Dec 14, 2009
    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.

    Further updates await somebody else with more expertise.
    
    Changes:

    x86, mce: Thermal monitoring depends on APIC being enabled

    cyrillos committed with Ingo Molnar Dec 14, 2009
    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.

  21. x86: Gart: fix breakage due to IOMMU initialization cleanup

    Yinghai Lu committed with Ingo Molnar Dec 14, 2009
    This fixes the following breakage of the commit
    75f1cdf:
    
    - 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().

    fujita committed with Ingo Molnar Dec 14, 2009
    The commit 75f1cdf 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

    fujita committed with Ingo Molnar Dec 14, 2009
    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

    mitake committed with Ingo Molnar Dec 13, 2009
    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]
    |
    |       10.999317 usecs/op
    |           90914 ops/sec
    |
    | % ./perf bench all                            # Test all suites of all subsystems
    | # Running sched/messaging benchmark...
    | # 20 sender and receiver processes per group
    | # 10 groups == 400 processes run
    |
    |      Total time: 0.420 [sec]
    |
    | # Running sched/pipe benchmark...
    | # Extecuted 1000000 pipe operations between two tasks
    |
    |      Total time: 11.741 [sec]
    |
    |       11.741346 usecs/op
    |           85169 ops/sec

    The noMMU syscall trap has a bug that causes R11 to be zero on return to
    userland. Remove the extra "save" of R11 responsible for the bug.
    
    Remove reloading of mode indicator because r11 already contains it.

    microblaze: Support for WB cache

    michalsimek committed Dec 10, 2009
    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.

    We need to continue with next microblaze PVR version that's why
    I have to remove that ancient version. These version strings not match
    any versions. From Microblaze v5.00.a is possible to use this style.
    I believe that none use ancients versions. If yes they will be just
    labeled as unknown version.
