* Filter out "default" transfer mode values (0x00 - default PIO mode, 0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted /proc/ide/hd?/settings:current_speed setting. Allowing "default" transfer mode values is a dangerous thing to do as we don't support programming controller to the "default" transfer mode and devices often use different values for the default and maximum PIO mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay programmed for higher PIO mode while device will use the lower PIO mode. There is no functionality loss as by using special IOCTLs device can still be programmed to "default" transfer modes (it is only useful for debugging/testing purposes anyway). * Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was previously used by few host drivers to program the controller to PIO0 timings for "default" transfer mode == 0x01 (although some host drivers would program invalid PIO timings instead). * Cleanup ide_set_xfer_rate() and add BUG_ON().

Lets remove dead Virtual DMA support for now so it doesn't clutter core IDE code (it can be bring back when there is a need for it): * Remove IDE_HFLAG_VDMA host flag. * Remove ide_drive_t.vdma flag. * cs5520.c: remove stale FIXMEs, cs5520_dma_host_set() and cs5520_dma_ops (also there is no longer a need to set IDE_HFLAG_NO_ATAPI_DMA). There should be no functional changes caused by this patch. Cc: TAKADA Yoshihito <takada@mbf.nifty.com> Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Alan Cox has noticed some time ago that hpt34x is broken (http://lkml.org/lkml/2007/7/3/257): "No the old driver doesn't even do that. It starts up. It spuriously adjusts some non writable PCI BAR registers, prints a message about resources being in use already then exits."

Stephen Rothwell points out that this file got deleted (on purpose) by commit 640c1bce ("USB: delete airprime driver"), but then almost immediately incorrectly resurrected by commit 95da310e ("usb_serial: API all change"). Delete it again. If it comes back, we'll need to drive a stake through its heart.

This patch completely reworks the RX path in order to be more accurate about what is going on with the MAC. We no longer read the error from the MLSR register instead read the descriptor status register which reflects, the error per descriptor. We now allocate skbs on the fly in r6040_rx, and we handle allocation failure instead of simply dropping the packet. Remove the rx_free_desc counter of r6040_private structure since we allocate skbs in the RX path. r6040_rx_buf_alloc is now removed and becomes unuseless.

Joseph Fannin <jfannin@gmail.com> and Takashi Iwai <tiwai@suse.de> noticed that commit 073a345c ("mv643xx_eth: clarify irq masking and unmasking") broke the mv643xx_eth build when NETPOLL is enabled, due to it not renaming one instance of INT_CAUSE_EXT in mv643xx_eth_netpoll().
