Kernel

[RFC] 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 the deferrable timers don't actually work at this point; I'm probably just doing something silly in the IPS driver in using them, but it's possible... 26 Mar 2010 20:27

[PATCH 23/24] x86, lmb: Use lmb_memory_size()/lmb_free_memory_size() to get correct dma_reserve
lmb_memory_size() will return memory size in lmb.memory.region. lmb_free_memory_size() will return free memory size in lmb.memory.region. So We can get exact reseved size. Set the size right after initmem_init(), because later bootmem API will get area from 16M. (except some fallback). Later after we remove ... 26 Mar 2010 19:13

[PATCH 18/24] lmb: Add reserve_lmb_overlap_ok()
Some areas from firmware could be reserved several times from different callers. If these area are overlapped, We may have overlapped entries in lmb.reserved.
