When the spi_mpc83xx driver receives a tx_buf pointer which is NULL, it
only writes one zero filled word to the transmit register. If the driver
expects to receive more than one word it will wait forever for a second
receive interrupt. With this patch the controller will shift out zeroes
until all words have been received.

The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
to account for this in the udma_filter() method. In order to achieve that, do
the following changes:
- install the method for all chips, not only HPT36x/370 and improve the code
formatting by killing the extra tabs while at it;
- add to the end of the 'switch' statement in the method cases for HPT372[AN]
and HPT374 chips upon which the known SATA cards are based;
- use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
behave correctly;
- move the HPT370[A] cases below the HPT36x case for consistency.
While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
all over the driver...

The IDE core never marked the PCI IDE devices as being in use after succesfull
driver probe call (the devices were marked in use only while being probed), and
so was susceptible to issues caused by unsolicited PCI hotplug device removal.
So, add pci_dev_get() call to ide_scan_pcidev() and convert this function to
the kernel style, also dropping a bunch of useless curly braces from its caller,
ide_scan_pcibus() and somewhat beautifying printk() call there, while at it...

In ocfs2_alloc_write_write_ctxt, the written clusters length is calculated
by the byte length only. This may cause some problems if we start to write
at some position in the end of one cluster and last to a second cluster
while the "len" is smaller than a cluster size. In that case, we have to
write 2 clusters actually.
So we have to take the start position into consideration also.

For some mount option types, ocfs2_parse_options() will try to access
sb->s_fs_info to get at the ocfs2 private superblock. Unfortunately, that
hasn't been allocated yet and will cause a kernel crash.
Fix this by storing options in a struct which can then get pushed into the
ocfs2_super once it's been allocated later. If we need more options which
store to the ocfs2_super in the future, we can just fields to this struct.

I would like have the attached patch added to Linux kernel. The three
usb flash memories listed in the patch are being used in Intel's
ClassmatePC and need USB_QUIRK_RESET_RESUME to work reliably when
resuming from ram.
The MP3/MP4/AVI player "Rockchip ROCK MP3" is seen as a USB disk, but fails
if more than 128 sectors (64kB) are sent or requested in a single read or write
command, and disconnects from the USB bus.
Typical kernel log showing the problem is:
usb 3-1: reset high speed USB device using ehci_hcd and address 6
usb 3-1: reset high speed USB device using ehci_hcd and address 6
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
usb 3-1: USB disconnect, address 6
This patch works around the device limitation by adding "Rockchip ROCK MP3"
to unusual USB devices list and limiting data transfers to 64 sectors (32kB)
per command.
Tested on 2.6.23-rc5 (amd64).
