2010-02-10HID: remove MODULE_VERSION from new driversJiri Kosina

2010-02-10HID: add a device driver for the Apple Magic Mouse.Michael Poole
The Magic Mouse requires that a driver send an unlock Report(Feature) command, similar to the Wacom wireless tablet and Sixaxis controller quirks. This turns on an Input Report that isn't published in the input Report descriptor that contains touch data (and usually overrides the normal motion and click Report). Because the mouse has only one switch and no scroll wheel, the driver (under control of parameters) emulates a middle button and scroll wheel. User space could also ignore and/or re-synthesize those events based on the reported events. Some user-space tools to talk to the mouse directly (that is, when it is not associated with the host's HIDP stack) are at http://github.com/entrope/linux-magicmouse Signed-off-by: Michael Poole <mdpoole@troilus.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2010-02-10sh: Fix up multi-resource mapping for SH7786 PCIe.Paul Mundt
This reworks some of the SH7786 PCIe initialization code to dynamically setup and size the various resource windows, as opposed to the original code that simply wired in a couple of them statically. At the same time, we tidy up the initialization code a bit, kill off some read-only register twiddling that was gleaned from the bus analyzer, and also propagate the physical slot/channel mapping.

2010-02-09x86, apic: Don't use logical-flat mode when CPU hotplug may exceed 8 CPUsSuresh Siddha
We need to fall back from logical-flat APIC mode to physical-flat mode when we have more than 8 CPUs. However, in the presence of CPU hotplug(with bios listing not enabled but possible cpus as disabled cpus in MADT), we have to consider the number of possible CPUs rather than the number of current CPUs; otherwise we may cross the 8-CPU boundary when CPUs are added later. 32bit apic code can use more cleanups (like the removal of vendor checks in 32bit default_setup_apic_routing()) and more unifications with 64bit code. Yinghai has some patches in works already. This patch addresses the boot issue that is reported in the virtualization guest context.

2010-02-10powerpc: Fix address masking bug in hpte_need_flush()David Gibson
Commit f71dc176aa06359681c30ba6877ffccab6fba3a6 'Make hpte_need_flush() correctly mask for multiple page sizes' introduced bug, which is triggered when a kernel with a 64k base page size is run on a system whose hardware does not 64k hash PTEs. In this case, we emulate 64k pages with multiple 4k hash PTEs, however in hpte_need_flush() we incorrectly only mask the hardware page size from the address, instead of the logical page size. This causes things to go wrong when we later attempt to iterate through the hardware subpages of the logical page. This patch corrects the error. It has been tested on pSeries bare metal by Michael Neuling. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* 'for-linus' of git://neil.brown.name/md: md: fix some lockdep issues between md and sysfs. md: fix 'degraded' calculation when starting a reshape.
2010-02-10md: fix some lockdep issues between md and sysfs.NeilBrown
====== This fix is related to http://bugzilla.kernel.org/show_bug.cgi?id=15142 but does not address that exact issue. ====== sysfs does like attributes being removed while they are being accessed (i.e. read or written) and waits for the access to complete. As accessing some md attributes takes the same lock that is held while removing those attributes a deadlock can occur. This patch addresses 3 issues in md that could lead to this deadlock. Two relate to calling flush_scheduled_work while the lock is held. This is probably a bad idea in general and as we use schedule_work to delete various sysfs objects it is particularly bad. In one case flush_scheduled_work is called from md_alloc (called by md_probe) called from do_md_run which holds the lock. This call is only present to ensure that ->gendisk is set. However we can be sure that gendisk is always set (though possibly we couldn't when that code was originally written. This is because do_md_run is called in three different contexts: 1/ from md_ioctl. This requires that md_open has succeeded, and it fails if ->gendisk is not set. 2/ from writing a sysfs attribute. This can only happen if the mddev has been registered in sysfs which happens in md_alloc after ->gendisk has been set. 3/ from autorun_array which is only called by autorun_devices, which checks for ->gendisk to be set before calling autorun_array. So the call to md_probe in do_md_run can be removed, and the check on ->gendisk can also go. In the other case flush_scheduled_work is being called in do_md_stop, purportedly to wait for all md_delayed_delete calls (which delete the component rdevs) to complete. However there really isn't any need to wait for them - they have already been disconnected in all important ways. The third issue is that raid5->stop() removes some attribute names while the lock is held. There is already some infrastructure in place to delay attribute removal until after the lock is released (using schedule_work). So extend that infrastructure to remove the raid5_attrs_group. This does not address all lockdep issues related to the sysfs "s_active" lock. The rest can be address by splitting that lockdep context between symlinks and non-symlinks which hopefully will happen.

2010-02-10drm/nv50: avoid unloading pgraph context when ctxprog is runningMaarten Maathuis
- We need to disable pgraph fifo access before checking the current channel, otherwise we could still hit a running ctxprog. - The writes to 0x400500 are already handled by pgraph->fifo_access and are therefore redundant, moreover pgraph fifo access should not be reenabled before current context is set as invalid.

2010-02-09ALSA: hda-intel: Avoid divide by zero crashJody Bruchon
On my AMD780V chipset, hda_intel.c can crash the kernel with a divide by zero for as-yet unknown reasons. A simple check for zero prevents it, though the problem that causes it remains. Since the workaround is harmless and won't affect anyone except victims of this bug, it should be safe; moreover, because this crash can be triggered by a user-mode application, there are denial of service implications on the systems affected by the bug without the patch.
