We want ->tf_read() to get a complete snapshot of all taskfile
registers, without requiring the callers to manually call
ata_chk_status() and ata_chk_err() themselves.
This also fixes a minor bug in sata_vsc where the lower bits of the
feature register were incorrectly placed in the HOB (high order bits)
portion of struct ata_taskfile.

as-iosched deals with aliased requests differently from other ioscheds.
It links together aliased requests using rq->queuelist instead of
spilling alises to dispatch queue like other ioscheds do. Requests
linked in this way cannot be merged.
Unfortunately, generic q->last_merge handling patch didn't take this
into account and q->last_merge could be set to an aliased request
resulting in Badness, corrupt list and eventually panic.
This explicitly marks aliased requests to be unmergeable.

Change the phys_mem_access_prot() function to take a pfn instead of an
address. This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.
Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn. Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.

Here is an uptodated version of the MPC8xx PCMCIA driver for v2.6,
addressing comments by Jeff and Dominik:
- use IO accessors instead of direct device memory referencing
- avoid usage of non-standard "uint/uchar" data types
- kill struct typedef's
Will submit it for inclusion once v2.6.14 is out.
Testing on 8xx platforms is more than welcome! Works like a charm

This patch (as588) fixes the way endpoint attribute files are registered
and unregistered. Now they will correctly track along with altsetting
changes. This fixes bugzilla entry #5467.
In a separate but related change, when a usb_reset_configuration call
fails, the device state is not changed to USB_STATE_ADDRESS. In the
first place, failure means that we don't know what the state is, not
that we know the device is unconfigured. In the second place, doing
this can potentially lead to a memory leak, since usbcore might not
realize there still is a current configuration that needs to be
destroyed.

This revised patch (as587b) improves the implementation of USB endpoint
sysfs files. Instead of storing a whole bunch of attributes for every
single endpoint, each endpoint now gets its own kobject and they can
share a static list of attributes. The number of extra fields added to
struct usb_host_endpoint has been reduced from 4 to 1.
The bEndpointAddress field is retained even though it is redundant (it
repeats the same information as the attributes' directory name). The
code avoids calling kobject_register, to prevent generating unwanted
hotplug events.

This patch allocates a separate buffer for usb-storage to use when

cache-coherent DMA or (b) have DMA alignment restrictions.

This patch is originally from Alan Stern (as557). It has been re-diffed
against a current tree, and I also corrected a minor merging error.
Some time ago we introduced a delay before device scanning, because many
devices do not like to receive SCSI commands right after enumeration.
Now it turns out there's a device that doesn't like to receive
Get-Max-LUN right after enumeration either. Accordingly this patch
delays the Get-Max-LUN request until the beginning of the scanning
procedure. This fixes Bugzilla entry #5010.
Three things are worth noting. First, I removed the locking code from
usb_stor_acquire_resources. It's not needed, because the locking is to
protect against disconnect events and acquire_resources is only called
during probe (so the disconnect routine can't be called). Second, I
initialized to 0 the buffer used for the Get-Max-LUN response. It's not
really necessary, but it will prevent random values from showing up in
the debugging log when the request fails. Third, I added a test against
the SINGLE_LUN flag. This will allow us to use the flag to indicate
Bulk-only devices that can't handle Get-Max-LUN.

Looks okay to me. Given that the previous entry uses the full 0000 -
9999 range, I guess this one can also. The vendor name is a little odd
