mtd: improve parameter parsing for block2mtd
Expand the parameter parsing for block2mtd. It now accepts:
Ki, Mi, Gi - the official prefixes for binary multiples,

ki - mistake on my side and analog to "k" for decimal multiples,
KiB, MiB, GiB - for people that prefer to add a "B" for byte,
kiB - combination of the above.
There were complaints about not accepting "k" for 1024. This has long
been common practice, but is known to lead to confusion. Hence the new

[JFFS2] Fix race in post-mount node checking
For a while now, we've postponed CRC-checking of data nodes to be done
by the GC thread, instead of being done while the user is waiting for
mount to finish. The GC thread would iterate through all the inodes on
the system and check each of their data nodes. It would skip over inodes
which had already been used or were already being read in by
read_inode(), because their data nodes would have been examined anyway.
However, we could sometimes reach the end of the for-each-inode loop and
still have some unchecked space left, if an inode we'd skipped was
_still_ in the process of being read. This fixes that race by actually
waiting for read_inode() to finish rather than just moving on.

[PATCH] dma doc updates

- The dma_map_sg() call results are used like pci_map_sg() results:
using sg_dma_address() and sg_dma_len(). That's not wholly obvious
to folk reading _only_ the "new" DMA-API.txt writeup.
- Buffers allocated by dma_alloc_coherent() may not be completely
free of coherency concerns ... some CPUs also have write buffers
that may need to be flushed.
- Cacheline coherence issues are now mentioned as being among issues
which affect dma buffers, and complicate/prevent using of static and
(especially) stack based buffers with the DMA calls.
I don't think many drivers currently need to worry about flushing write
buffers, but I did hit it with one SOC using external SDRAM for DMA
descriptors: without explicit writebuffer flushing, the on-chip DMA
controller accessed descriptors before the CPU completed the writes.

[PATCH] arch/i386/pci/irq.c - new VIA chipsets (fwd)
I use 2.6.15.6 Linux kernel and found some problems. I have about 100
Linux boxes (all with the same (binary the same) kernel). Last time I have
upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2,
.4 and .6) and I have found some problems on VIA based PC's. Probably the
reason of this is that some VIA chipsets are unrecognized by IRQ router.
In line 586 there is: /* FIXME: add new ones for 8233/5 */
There were only a few of chipsets ID's there, some of my VIA chipsets were
not present and kernel used default IRQ router.
I have added three entries, so that the code looks like:
case PCI_DEVICE_ID_VIA_82C596:
case PCI_DEVICE_ID_VIA_82C686:
case PCI_DEVICE_ID_VIA_8231:
case PCI_DEVICE_ID_VIA_8233A:
case PCI_DEVICE_ID_VIA_8235:
case PCI_DEVICE_ID_VIA_8237:
case PCI_DEVICE_ID_VIA_8237_SATA:
/* FIXME: add new ones for 8233/5 */
r->name = "VIA";
r->get = pirq_via_get;
r->set = pirq_via_set;
return 1;
}
The kernel goes fine but I haven't testes it for weeks, I'm just a moment
after reboot :)
One thing is different (better?):
Using previus kernel I had:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0
now I have:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11
Maybe it is good idea to add there some more VIA chipsets?
The ones I have added seem to be OK.

The manual driver <-> device binding attribute in sysfs doesn't return

driver_probe_device returns 1 on success (the driver accepted the
device) or 0 on probe failure (when the driver didn't accept the
device but no real error occured). However, the attribute can't just
return 0 or 1, it must return the number of bytes consumed from buf
or an error value. Returning 0 indicates to userspace that nothing
was written (even though the kernel has tried to do the bind/probe and
failed). Returning 1 indicates that only one character was accepted in
which case userspace will re-try the write with a partial string.
A more correct version of driver_bind would return count (to indicate
the entire string was consumed) when driver_probe_device returns 1
and -ENODEV when driver_probe_device returns 0. This patch makes that

[PATCH] USB: Rename ax8817x_func() to asix_func() and add utility functions to reduce bloat
Now that the ASIX code is supporting more than just the AX88172 devices,
make the utility function names more generic: ax8817x_func -> asix_func.
Functions that are chip specific now indicate as such: ax88772_func.
Additionally, pull some common routines used in initialization and such
into simple functions to reduce the verbosity of certain functions such
as
the bind() routines and to make the error handling consistent across the
board.

Be sure to record the peripheral's ep0 maxpacket size BEFORE using

[PATCH] USB: usbtest: scatterlist OUT data pattern testing
Previously, scatterlist tests didn't write patterned data. Given how many
corner cases are addresed by them, this was a significant gap in Linux-USB
test coverage. Moreover, when peripherals checked for correct data patterns,
false error reports would drown out the true ones.
This adds the pattern on the way OUT from the host, so scatterlist tests can
now be used to uncover bugs like host TX or peripheral RX paths failing for
back-to-back short packets. It's easy enough to get an error there with at
least one of the {DMA,PIO}{RX,TX} code paths, or run into hardware races
that need to be defended against.
Note this patch doesn't add checking for correct data patterns on the way
IN from peripherals, just a FIXME for later.

This catches up to a change in the Kconfig support for highspeed modes;
the change predated 2.6.10, and anyone using gadgetfs on a highspeed

This patch (as664) adds a comment to file_storage.c, noting that the
driver is slightly non-portable because it assumes that a buffer

[PATCH] USB: g_file_storage: Set short_not_ok for bulk-out transfers
I'm told that some UDC hardware may work better if it knows that
receiving a short packet should always cause an error. Accordingly,
this patch (as663) sets the short_not_ok flag for bulk-out transfers in
g_file_storage. Oddly enough, there are no circumstances where that
driver can legally receive a shorter-than-expected bulk-out packet.

Below is a patch to gadgets/net2280.[ch] which adds support for the
net2282 controller. The original code was kindly provided by PLX
Technology, I just merged it with the current net2280 driver in the
kernel. Tested on 2.6.15.6, but only with 2282. I did the merge, so
that the behaviour for the 2280 is unaffected (except for short delays
for extra checks).
