2011-05-20HID: hiddev: fix race between hiddev_disconnect and hiddev_releaseJiri Kosina
When hiddev_disconnect() runs with chardev open, it will proceed with usbhid_close(). When userspace in parallel runs the hiddev_release(), it sees !hiddev->exists (as it has been already set so by hiddev_disconnect()) and kfrees hiddev while hiddev_disconnect() hasn't finished yet. Serialize the access to hiddev->exists and hiddev->open by existancelock. Reported-by: mike-@cinci.rr.com Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-05-20HID: magicmouse: ignore 'ivalid report id' while switching modesJiri Kosina
The device reponds with 'invalid report id' when feature report switching it into multitouch mode is sent to it. This has been silently ignored before 0825411ade ("HID: bt: Wait for ACK on Sent Reports"), but since this commit, it propagates -EIO from the _raw callback . So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's how the device reacts in normal mode. Sad, but following reality. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=35022 Tested-by: Chase Douglas <chase.douglas@canonical.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2011-05-20powerpc: Fix hard CPU IDs detectionBenjamin Herrenschmidt
commit 9d07bc841c9779b4d7902e417f4e509996ce805d "powerpc: Properly handshake CPUs going out of boot spin loop" Would cause a miscalculation of the hard CPU ID. It removes breaking out of the loop when finding a match with a processor, thus the "i" used as an index in the intserv array is always incorrect This broke interrupt on my PowerMac laptop.

2011-05-20extable, core_kernel_data(): Make sure all archs define _sdataSteven Rostedt
A new utility function (core_kernel_data()) is used to determine if a passed in address is part of core kernel data or not. It may or may not return true for RO data, but this utility must work for RW data. Thus both _sdata and _edata must be defined and continuous, without .init sections that may later be freed and replaced by volatile memory (memory that can be freed). This utility function is used to determine if data is safe from ever being freed. Thus it should return true for all RW global data that is not in a module or has been allocated, or false otherwise. Also change core_kernel_data() back to the more precise _sdata condition and document the function.
