USB: oti6858 usb-serial driver (in Nokia CA-42 cable)
Last week I've been searching for a driver for the CA-42 cable (see usb
below) that fitted my kernel 2.6.20. I only found an abandoned version for a
driver on your website that indeed worked on 2.6.18 but wouldn't even
compile with a more recent 2.6.20 kernel.
I fiddled 2 evenings with the kernel code and have patched it up now to work
with the modifications in the 2.6.20 kernel. The patch is attached hereafter
and it works fine (at least for me :-) ).
Bus 2 Device 13: ID 0ea0:6858 Ours Technology, Inc.
I had to fiddle a little with the settings in .gnokiirc but that also
occurred with the older 2.6.18 kernel. Nevertheless, on one system with this
cable and my Nokia 6070 I had best results with :
model = 6510
connection = dku5
while on an other system with the same kernel, cable and phone it only worked
with :
model = AT
connection = serial
serial_write_usleep = 1

USB: make hub driver's release more robust
This revised patch (as893c) improves the method used by the hub driver

USB: move bus_suspend and bus_resume method calls
This patch (as885) moves the root-hub bus_suspend() and bus_resume()
method calls from the hub driver's suspend and resume methods into the
usb_generic driver methods, where they make just as much sense.
Their old locations were not fully correct. For example, in a kernel
compiled without CONFIG_USB_SUSPEND, if one were to do:
echo -n 1-0:1.0 >/sys/bus/usb/drivers/hub/unbind
to unbind the hub driver from a root hub, there would then be no way
to suspend that root hub. Attempts to put the system to sleep would
fail; the USB controller driver would refuse to suspend because the
root hub was still active.
The patch also makes a very slight change in the way devices with no
driver are handled during suspend. Rather than doing a standard USB
port-suspend directly, now the suspend routine in usb_generic is
called. In practice this should never affect anyone.

This patch implements supports for EHCI controllers whose in-memory
data structures are represented in big-endian format. This is needed
(unfortunately) for the AMCC PPC440EPx SoC EHCI controller; the EHCI
spec doesn't specify little-endian format, although that's what most
other implementations use.
The guts of the patch are to introduce the hc32 type and change all
references from le32 to hc32. All access routines are converted from
cpu_to_le32(...) to cpu_to_hc32(ehci, ...) and similar for the other
"direction". (This is the same approach used with OHCI.)
David fixed:
Whitespace fixes; refresh against ehci cpufreq patch; move glue
for that PPC driver to the patch adding it; fix free symbol
capture bugs in modified "constant" macros; and make "hc32" etc

dm raid1: handle resync failures
Device-mapper mirroring currently takes a best effort approach to
recovery - failures during mirror synchronization are completely ignored.
This means that regions are marked 'in-sync' and 'clean' and removed
from the hash list. Future reads and writes that query the region
will incorrectly interpret the region as in-sync.
This patch handles failures during the recovery process. If a failure
occurs, the region is marked as 'not-in-sync' (aka RH_NOSYNC) and added
to a new list 'failed_recovered_regions'.
Regions on the 'failed_recovered_regions' list are not marked as 'clean'
upon removal from the list. Furthermore, if the DM_RAID1_HANDLE_ERRORS
flag is set, the region is marked as 'not-in-sync'. This action prevents
any future read-balancing from choosing an invalid device because of the
'not-in-sync' status.
If "handle_errors" is not specified when creating a mirror (leaving the
DM_RAID1_HANDLE_ERRORS flag unset), failures will be ignored exactly as they
would be without this patch. This is to preserve backwards compatibility with
user-space tools, such as 'pvmove'. However, since future read-balancing
policies will rely on the correct sync status of a region, a user must choose
"handle_errors" when using read-balancing.

A clear_region function is permitted to block (in practice, rare) but gets

The bits being marked and cleared by the above functions are used

perform these operations outside the spinlock since the

- mark_region in rh_inc()
- clear_region in rh_update_states().
So, we grab the clean_regions list items via list_splice() within the
spinlock and defer clear_region() until we iterate over the list for
deletion - similar to how the recovered_regions list is already handled.
We then move the flush() call down to ensure it encapsulates the changes

The relocatable kernel code needs a scratch field for the decompressor
to determine its own location. It was using a location inside
struct screen_info; reserve a free location and document it as scratch
instead.

Use a new CPU feature word to cover features that are spread around
Some Intel features are spread around in different CPUID leafs like 0x5,
0x6 and 0xA. Make this feature detection code common across i386 and
x86_64.
Display Intel Dynamic Acceleration feature in /proc/cpuinfo. This feature
will be enabled automatically by current acpi-cpufreq driver.
Refer to Intel Software Developer's Manual for more details about the feature.
Thanks to hpa (H Peter Anvin) for the making the actual code detecting the
scattered features data-driven.

hd.c: remove BIOS/CMOS queries
An ST-506 disk these days is pretty much someone trying to pull ancient
data using an auxilliary controller. Pulling data from the BIOS or CMOS
is just plain wrong, since it's likely to be the primary OS disk... and
would be user-entered data anyway. Instead, require the user enters it
on the command line.

[MIPS] SMTC: Interrupt mask backstop hack
To support multiple TC microthreads acting as "CPUs" within a VPE,
VPE-wide interrupt mask bits must be specially manipulated during
interrupt handling. To support legacy drivers and interrupt controller
management code, SMTC has a "backstop" to track and if necessary restore
the interrupt mask. This has some performance impact on interrupt service
overhead. Disable it only if you know what you are doing.
