2011-03-31Input: uinput - allow for 0/0 min/max on absolute axes.Peter Hutterer
Some devices provide absolute axes with min/max of 0/0 (e.g. wacom's ABS_MISC axis). Current uinput restrictions do not allow duplication of these devices and require hacks in userspace to work around this. If the kernel accepts physical devices with a min/max of 0/0, uinput shouldn't disallow the same range.

2011-03-30gpio/pca953x: fix error handling path in probe() callBen Dooks
If the device fails to respond, then the error path tries to remove an interrupt that never got registered, which causes an backtrace from the interrupt handling code. Fix this by ensuring that the cleanup path has two labels and use the correct path as needed. fixes the following error: WARNING: at kernel/irq/manage.c:908 __free_irq+0x80/0x160() Trying to free already-free IRQ 0 Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-03-30connector: convert to synchronous netlink message processingPatrick McHardy
Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms) and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct netlink_skb_parms) removed some members from struct netlink_skb_parms that depend on the current context, all netlink users are now required to do synchronous message processing. connector however queues received messages and processes them in a work queue, which is not valid anymore. This patch converts connector to do synchronous message processing by invoking the registered callback handler directly from the netlink receive function. In order to avoid invoking the callback with connector locks held, a reference count is added to struct cn_callback_entry, the reference is taken when finding a matching callback entry on the device's queue_list and released after the callback handler has been invoked.

2011-03-30atm/solos-pci: Don't flap VCs when carrier state changesPhilip A. Prindeville
Don't flap VCs when carrier state changes; higher-level protocols can detect loss of connectivity and act accordingly. This is more consistent with how other network interfaces work. We no longer use release_vccs() so we can delete it. release_vccs() was duplicated from net/atm/common.c; make the corresponding function exported, since other code duplicates it and could leverage it if it were public.

2011-03-30atm/solos-pci: Don't include frame pseudo-header on transmit hex-dumpPhilip A. Prindeville
Omit pkt_hdr preamble when dumping transmitted packet as hex-dump; we can pull this up because the frame has already been sent, and dumping it is the last thing we do with it before freeing it. Also include the size, vpi, and vci in the debug as is done on receive. Use "port" consistently instead of "device" intermittently.

According to Thomas, the former is the correct direct conversion, but it does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c seems to initialize both to the same thing), and the chip data in some ways is the more logical. Somebody should really decide on one of the other. This merge picks irq_desc_get_handler_data() as the straightforward pure conversion to new names, as per Thomas.

The UARTs may be located on different APB buses, thus have different UART clock frequency.

2011-03-30net/usb: Ethernet quirks for the LG-VL600 4G modemAndrzej Zaborowski
This adds a driver for the CDC Ethernet part of this modem. The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps. Userspace scripts are required to talk to the CDC ACM port. Signed-off-by: Andrzej Zaborowski <balrogg@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-29watchdog: softdog.c: enhancement to optionally invoke panic instead of ↵Anithra P Janakiraman
reboot on timer expiry This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

Stefano found SP5100 TCO watchdog driver using wrong address. [ 9.148536] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01 [ 9.148628] DEBUG __ioremap_caller WARNING address=b8fe00 size=8 valid=1 reserved=1 and e820 said that range is RAM. We should check if we can use that reading out. BIOS could just program wrong address there.

2011-03-29watchdog: Convert release_resource to release_region/release_mem_regionJulia Lawall
Request_mem_region should be used with release_mem_region, not release_resource. In pnx4008_wdt.c, a missing clk_put is added as well. The semantic match that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,E; @@ *x = request_mem_region(...) ... when != release_mem_region(x) when != x = E * release_resource(x); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Cc: stable <stable@kernel.org>

2011-03-29x86: Stop including <linux/delay.h> in two asm header filesJean Delvare
Stop including <linux/delay.h> in x86 header files which don't need it. This will let the compiler complain when this header is not included by source files when it should, so that contributors can fix the problem before building on other architectures starts to fail. Credits go to Geert for the idea. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: James E.J.
