2007-07-20mm: Remove slab destructors from kmem_cache_create().Paul Mundt
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).

2007-07-20ide: add support for SCSI ioctls to ide-floppyBartlomiej Zolnierkiewicz
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).

2007-07-20serverworks: fix DMABartlomiej Zolnierkiewicz
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. * Bump driver version.

* 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 - minor cleanups Reviewed-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-07-19i386: Allow KVM on i386 nonpaeAvi Kivity
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).
