Intelligent power sharing driver
This patchset adds the core IPS driver to drivers/platform/x86, along with some helper code in the timer subsystem to allow for deferrable on-stack timers. Note that this patchset doesn't include the i915 specific bits for monitoring power consumption. We're doing final validation on those now so I expect to be... 10 May 2010 17:40

[PATCH] perf: allow forcing use of cplus_demangle
For Fedora, I want to force perf to link against libiberty.a for cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity on binutils. (libiberty is LGPL2, libbfd is GPL3.) If we just rely on autodetection, we'll end up with libbfd linked against us, since they're both in binutils-static in... 10 May 2010 17:40
magicmouse: claimed by neither input, hiddev nor hidraw

[PATCH 1/4] INIT_TASK() should initialize ->thread_group list
The trivial /sbin/init doing int main(void) { kill(0, SIGKILL) } crashes the kernel. This happens because __kill_pgrp_info(init_struct_pid) also sends SIGKILL to the swapper process which runs with the uninitialized ->thread_group. Change INIT_TASK() to initialize ->thread_group properly. Note: ... 10 May 2010 16:33
