2007-10-11[NET]: Fix NAPI completion handling in some drivers.David S. Miller
In order for the list handling in net_rx_action() to be correct, drivers must follow certain rules as stated by this comment in net_rx_action(): /* Drivers must not modify the NAPI state if they * consume the entire weight. In such cases this code * still "owns" the NAPI instance and therefore can * move the instance around on the list at-will. */ A few drivers do not do this because they mix the budget checks with reading hardware state, resulting in crashes like the one reported by takano@axe-inc.co.jp.

2007-10-11icside: fix ->speedproc to return on unsupported modes (take 5)Bartlomiej Zolnierkiewicz
* All other implementations of ->speedproc return zero on success and non-zero on failure. Currently it doesn't matter for icside host driver and isn't a bug per se since: - ide_set_xfer_rate() return value is ignored by all IDE core users - icside doesn't (yet!) use ide_tune_dma() in icside_dma_check() but sooner or later we will need to fix anyway - so lets do it now. * icside_set_speed() happily accepts unsupported transfer modes which results in drive->drive_data being set to the maximum value (480) and drive->current_speed being set to the unsupported transfer mode. Fix it. v2: * The initial version of the patch was broken because it didn't take into the account (the different from usual) return values of icside_set_speed() (Noticed by Russell). v3: * Remove no longer needed initialization/checking of cycle_time (Noticed by Sergei). * No need to set drive->drive_data if DMA is not going to be used (Noticed by Sergei). * Remove incorrect setting of drive->current_speed (Noticed by Sergei). * Move ide_config_drive_speed() at the end of icside_set_speed(). v4: * If DMA mode is not found in icside_dma_check() then just return "-1" and don't call icside_set_speed() (v3 got it wrong and "1" was returned instead). v5: * Return "-1"/"0" in icside_set_speed() instead of icside_dma_check() return value (just like it was before this patch).

2007-10-11sgiioc4: use ide_tune_dma()Bartlomiej Zolnierkiewicz
* Add DRV_NAME define and use it instead of sgiioc4_chipset.name. * Remove no longer needed sgiioc4_chipset. * Remove needless clearing of ->atapi_dma from ide_dma_sgiioc4(). * Fix ide_dma_sgiioc4() to return success/failure. Check return value in sgiioc4_ide_setup_pci_device() and set hwif->autodma accordingly. Also add missing setting of drive->autodma. * Add sgiioc4_speedproc() (implementation of ->speedproc method). * Fix ->mwdma_mask (MWDMA2 mask is 0x04 not 0x02) and remove incorrect ->swdma_mask. Also remove needless initialization of ->ultra_mask. * Use ide_tune_dma() in sgiioc4_ide_dma_check(), this fixes following bugs: - DMA capability bit not being checked on the device - DMA blacklist not being checked - MWDMA2 mode support by device not being checked Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Jeremy Higdon <jeremy@sgi.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-11amd74xx/via82cxxx: use ide_tune_dma()Bartlomiej Zolnierkiewicz
* Use ide_tune_dma() in amd74xx/via82cxxx driver, this fixes following bugs: - DMA capability bit not being checked on the device - DMA blacklist not being checked - DMA mode being programmed even if drive->autodma == 0 (thus possibly destroying PIO timings) * Bump driver version.

2007-10-11ide: add ide_set{_max}_pio() (take 4)Bartlomiej Zolnierkiewicz
* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags and set them in ht6560, cmd640, cmd64x and sc1200 host drivers. * Add set_pio_mode_abuse() for checking if host driver has a non-standard ->tuneproc() implementation and use it in do_special(). * Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find the maximum PIO mode supported by the host), also add ide_set_max_pio() wrapper for ide_set_pio() to use for auto-tuning. Convert users of ->tuneproc to use ide_set{_max}_pio() where possible. This leaves only do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as a direct users of ->tuneproc. * Remove no longer needed ide_get_best_pio_mode() calls and printk-s reporting PIO mode selected from ->tuneproc implementations. * Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const. * Remove stale comment from ide_config_drive_speed(). v2: * Fix "ata_" prefix (Noticed by Jeff). v3: * Minor cleanups/fixups per Sergei's suggestions. v4: * Fix compile problem in drivers/ide/pci/cmd640.c (Noticed by Andrew Morton). * Improve some ->set_pio_mode comments.

2007-10-11ide: Kconfig face-liftBartlomiej Zolnierkiewicz
* Convert config options for PCI host drivers to select BLK_DEV_IDEPCI. * Same for BLK_DEV_IDEDMA_PCI and PCI DMA host drivers, also make this config option select BLK_DEV_IDEPCI. * Remove no longer needed help for BLK_DEV_IDEPCI and BLK_DEV_IDEDMA_PCI. * Remove redundant IDE_CHIPSETS config option. As a result of this patch users have now three less config options to worry about and can just select host drivers that they need (IDE config menu is "flatter").

2007-10-11ide: move ide_rate_filter() calls to the upper layer (take 2)Bartlomiej Zolnierkiewicz
* Move ide_rate_filter() calls from host drivers to IDE core. * Make ide_rate_filter() static. * Make 'speed' argument of ->speedproc const. v2: * Fix it8213_tune_chipset() comment.
