Merge git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6: (24 commits) ide: use only ->set_pio_mode method for programming PIO modes (take 2) sis5513: don't change UDMA settings when programming PIO it8213/piix/slc90e66: don't change DMA settings when programming PIO alim15x3: PIO mode setup fixes siimage: fix ->set_pio_mode method to select PIO data transfer cs5520: don't enable VDMA in ->speedproc sc1200: remove redundant warning message from sc1200_tune_chipset() ide-pmac: PIO mode setup fixes (take 3) icside: fix ->speedproc to return on unsupported modes (take 5) sgiioc4: use ide_tune_dma() amd74xx/via82cxxx: use ide_tune_dma() ide: add ide_set{_max}_pio() (take 4) ide: Kconfig face-lift ide: move ide_rate_filter() calls to the upper layer (take 2) sis5513: add ->udma_filter method for chipset_family >= ATA_133 ide: mode limiting fixes for user requested speed changes ide: add missing ide_rate_filter() calls to ->speedproc()-s ide: call udma_filter() before resorting to the UltraDMA mask ide: make jmicron match vendor and device class pdc202xx_new: switch to using pci_get_slot() (take 2) ...
