[patch] libata: ata_piix.c PIO fix "[libata] transfer mode cleanup" introduced bug in ata_piix.c: previously PIO number (not mode) was passed to piix_set_piomode(). Fortunately this function is only used for (disabled) PATA support. I bet that this is the reason why MWDMA didn't work for PATA. Signed-off-by:Bartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl>

This patch fixes a problem introduced when CK804 support was added. mmio_base can only be set in the CK804 case, else libata will attempt to iounmap mmio_base, which isn't iomapped for the non-CK804 case. Still need the bar 5 address, so steal from host_set->ports[0]->ioaddr.scr_addr. Jeff, let me know if this is a bad thing to do.

We seem to have found an overflow problem in libata-core.c. We were trying to DMA to the address range 0xffff8000-0xffffbfff. In the original version of the code, given that address and count (0xffff8000 and 0x4000), the variable "boundary" would be set to 0, causing len to be set to 0x8000 (which is greater than sg_len). Then at the bottom of the loop, sg_len would be set to 0xffffc000 (0x4000 - 0x8000), which would then cause the loop never to terminate (until much of memory was scribbled over or the kernel died). The code below should be functionally identical, but not be subject to the same overflow problem (boundary needs to be a u33).

From: Alan Cox <alan@redhat.com> Some interfaces (notably PCMCIA ones) don't decode the master/slave select so you get two copies of a device appearing and bad things happening if a user accidentally uses both. This checks for the model/serial matching but also knows about non ATA drives ide=noprobe and a Maxtor problem that was found in Andrew's testing of an earlier patch. Although M00000.. drives should be RMA'd to Maxtor (and with info on where they were obtained...) we don't want to break anyone who has them. Signed-off-by:

From: Alan Cox <alan@redhat.com> If you get invalid geometry (eg a failed drive) the box hangs on boot because we try and unregister the registered driver and end up in a locking mess. We change the behaviour to simply leave the device unattached which avoids the mess. Signed-off-by:

From: Alan Cox <alan@redhat.com> This was put in for PPC specifically and defined in the 2.4 tree to be paranoid about breaking stuff. The actual wait for hwif spin up is however perfectly correct for all drives. In the normal PC case the PC BIOS has done this but with other embedded boxes and with things like LinuxBIOS it may not have done. Thus it should always be done. Signed-off-by:

As noticed by Alan Cox: "It doesn't work now so it clearly isnt being used 8). We hold the lock because its a proc function and we then replace the proc functions in the attach method -> deadlock. It is also incredibly hard to fix without a major rewrite." The same is true for HDIO_SET_IDE_SCSI ioctl. Both were broken 18 months ago in 2.5.63 as a side-effect of locking fixes. Signed-off-by:

Let's leave the code for a while yet, and see if somebody screams. But both Red Hat and SuSE claim it is unused, so it probably is. The driver hasn't gotten updated in years, and google doesn't seem to show any usage either.

* long constant in a.out.h * missing cast to pointer in pgtable.h * removed useless __chk_user_ptr() in get_user() and put_user() - with fixed typeof handling in sparse we are getting the check from __typeof__(*(ptr)) __user *__pu_addr = (ptr); \ anyway, so __chk_user_ptr() is redundant there.

It used to create totally impossible resource trees in some circumstances where it was asked to insert a conflicting resource. We never noticed, because it wasn't used that much. Make it return the proper error instead.
