2008-02-01PCI: Remove users of pci_enable_device_bars()Benjamin Herrenschmidt
This patch converts users of pci_enable_device_bars() to the new pci_enable_device_{io,mem} interface. The new API fits nicely, except maybe for the QLA case where a bit of code re-organization might be a good idea but I prefer sticking to the simple patch as I don't have hardware to test on. I'll also need some feedback on the cs5520 change. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-02-01sata_nv: fix for completion handlingRobert Hancock
This patch is based on an original patch from Kuan Luo of NVIDIA, posted under subject "fixed a bug of adma in rhel4u5 with HDS7250SASUN500G". His description follows. I've reworked it a bit to avoid some unnecessary repeated checks but it should be functionally identical. "The patch is to solve the error message "ata1: CPB flags CMD err, flags=0x11" when testing HDS7250SASUN500G in rhel4u5. I tested this hd in 2.6.24-rc7 which needed to remove the mask in blacklist to run the ncq and the same error also showed up. I traced the bug and found that the interrupt finished a command (for example, tag=0) when the driver got that adma status is NV_ADMA_STAT_DONE and cpb->resp_flags is NV_CPB_RESP_DONE. However, For this hd, the drive maybe didn't clear bit 0 at this moment. It meaned the hardware had not completely finished the command. If at the same time the driver freed the command(tag 0) and sended another command (tag 0), the error happened. The notifier register is 32-bit register containing notifier value. Value is bit vector containing one bit per tag number (0-31) in corresponding bit positions (bit 0 is for tag 0, etc). When bit is set then ADMA indicates that command with corresponding tag number completed execution. So i added the check notifier code. Sometimes i saw that the notifier reg set some bits , but the adma status set NV_ADMA_STAT_CMD_COMPLETE ,not NV_ADMA_STAT_DONE. So i added the NV_ADMA_STAT_CMD_COMPLETE check code."

2008-01-23[SCSI] libata: fix corruption induced by relaxed DMA alignment in SCSIJames Bottomley
Hugh Dickens noticed that SMART commands issued from user space can end up corupting memory. The problem occurs if the buffer used to read data spans two pages. The reason is that the PIO sector routines in libata are expecting physically contiguous pages when they do sector operations, so the left overs on the second page go into the next physically adjacent page rather than the next page in the sg mapping. Fix this by enforcing strict 512 byte alignment on all buffers from userspace.

ATA_ECAT_DUBIOUS_BASE was too high by one and thus all DUBIOUS error categorizations were wrong.

2008-01-23ata_piix: implement SIDPR SCR accessTejun Heo
For ICH8, SCRs can be accessed using index and data register pair located at BAR 5. This patch implements support for it such that PHY status, errors and hardreset are available for those controllers. This is the only case where two devices on a PATA channel have access to SCRs and creates a unique problem of mapping two SCRs to one link. Note that this is different from PMP case in that they aren't quite separate links - e.g. softreset resets both devices. This problem is worked around by merging the SCR values. To upper layer, it looks like there is a single link with one set of SCRs but with two devices. This works well enough for PHY event, error reporting and hardreset. Supporting hardreset is important because in rare cases SATA devices fail to recover without it after PHY errors.

2008-01-23ata_piix: convert to prepare - activate initializationTejun Heo
ata_piix requires more configuration during initialization than most other SFF compliant controllers and one-go initialzation with ata_pci_one() is too rigid. This patch converts ata_piix to use two step prepare - activate initialization used by other more advanced controllers. This conversion brings the happy side effect of enabling PCI device before accessing PCI configuration registers. Other than that, there shouldn't be any behavior change.

Update the legacy driver so it can handle VLB ports nicely, and has an internal structure for nailing new ISA/VLB forms in. Anyone got an ALI14xx and a spare day ;) Also adds an "all" parameter so you can load this driver after all the PCI ones in a boot time kernel and tell it to grab anything ST412 compatible even if it is an unknown PCI device.
