  • Slab destructors were no longer supported after Christoph's
    c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
    BUGs for both slab and slub, and slob never supported them
    either.

    This rips out support for the dtor pointer from kmem_cache_create()
    completely and fixes up every single callsite in the kernel (there were
    about 224, not including the slab allocator definitions themselves,
    or the documentation references).

  • a) switch by loff_t == __cmpdi2 use. Replaced with a couple
    of obvious ifs; update of ->f_pos in the first one makes sure that we
    do the right thing in all cases.
    b) block_signals() and unblock_signals() are globals on UML.
    Renamed coda ones; in principle UML probably ought to do rename as
    well, but that's another story.

  • Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
    (except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
    ones - we can add them later iff really needed).

    While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
    generic_ide_ioctl():

    - This prevents ide-{disk,tape,scsi} device drivers from obtaining
    REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
    these drivers and which are potentially harmful (as reported by Andrew).

    - There is no functionality loss since aforementioned ioctls will now be
    handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
    ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
    (for devices using ide-cd driver).

    and teach ide_get_best_pio_mode() about them. Also remove needless
    !drive->id check while at it (drive->id is always present).

    * Convert amd74xx, via82cxxx and ide-timing.h to use ide_get_best_pio_mode()

    from sc1200_resume().

  • The driver used to depend on BIOS settings for deciding whether it is OK
    to use DMA. However it seems that BIOS doesn't always handle all cases
    correctly so just let IDE core to decide about this. It should be a safe
    thing to do now, after the driver went through heavy bugfixing.

    Thanks for bugreport and testing the patch goes out to Sven Niedner.

  • * Always set ->autotune so PIO gets correctly auto-tuned (previously
    ->autotune was only set when ->dma_base wasn't available, however
    ->ide_dma_check()/->speedproc() was always trying to tune PIO when
    tuning DMA).

    * Move code responsible for programming chipset for PIO mode from
    svwks_tune_chipset() to svwks_tune_pio(). Don't tune PIO when tuning
    DMA (this is no longer needed since ->autotune is always set now).

    * Handle PIO modes early in svwks_tune_chipset() so DMA configuration
    registers don't get cleared when programming PIO mode.

  • * Add sil_tuneproc() wrapper for siimage_tuneproc() which also sets
    PIO mode on the device.

    * Add missing ide_get_best_pio_mode() call to sil_tuneproc() so
    "pio" == 255 (autotune) is handled correctly (previously PIO0 was used)
    and "pio" values > 4 && < 255 are filtered to PIO4 (instead of PIO0).

    * Add code limiting maximum PIO mode according to the pair device capabilities
    to sil_tuneproc().

    * Convert users of config_siimage_chipset_for_pio() to use sil_tune_pio() and
    sil_tuneproc(). This fixes PIO fallback in siimage_config_drive_for_dma() to
    use max PIO mode available instead of PIO4 (config_siimage_chipset_for_pio()
    used wrong arguments for ide_get_best_pio_mode() and as a results always
    tried to set PIO4).

    * Remove no longer needed siimage_taskfile_timing()
    and config_siimage_chipset_for_pio().

    * Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
    from siimage_speedproc()

    * Bump driver version.

    v2:
    * Fix issues noticed by Sergei:
    - correct pair device check
    - trim only taskfile PIO to the slowest of the master/slave
    - enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
    from siimage_speedproc()
    - add TODO item for IORDY bugs

    and then add setting device PIO mode to atiixp_tuneproc().

    * Add missing ide_get_best_pio_mode() call to atiixp_tuneproc() so
    "pio" == 255 (autotune) is handled correctly and "pio" values > 4 && < 255
    are filtered to PIO4 (previously "pio" == 5 could result in wrong timings
    being used and "pio" values > 4 && < 255 in an OOPS).

    * Handle PIO modes early in atiixp_speedproc() so save_mdma_mode[]
    doesn't get cleared.

    * In atiixp_dma_check():
    - fix max_mode argument for ide_get_best_pio_mode()
    - don't call atiixp_dma_2_pio() so PIO1 doesn't get remapped to PIO0
    - use atiixp_tuneproc() instead of atiixp_speedproc()

  • Various old IDE drivers go mapping ROM devices for no apparent reason and
    without using the ROM mapping API we now have. They don't actually use
    the ROM they map and the new libata drivers are happy without it being
    mapped so rather than port them lets just junk it for the next -rc1.

  • Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
    the cmpxchg64b feature and enables compilation of the set_64bit() family.
    Since the option is dependent on PAE, and since KVM depends on set_64bit(),
    this effectively disables KVM on i386 nopae.

    Simplify by removing the config option altogether: the boot check is made
    dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
    without constraints. It is up to users to check for the feature flag (KVM
    does not as virtualiation extensions imply its existence).

  • When a CONFIG_USER_NS=n and a user tries to unshare some namespace other
    than the user namespace, the dummy copy_user_ns returns NULL rather than
    the old_ns.

    This value then gets assigned to task->nsproxy->user_ns, so that a
    subsequent setuid, which uses task->nsproxy->user_ns, causes a NULL
    pointer deref.

    Fix this by returning old_ns.
