[PATCH] rcu: don't call rcu_preempt_note_context_switch() in rcu_check_callbacks()
Even though in user mode or idle mode, rcu_check_callbacks() is not context switch, so we don't call rcu_preempt_note_context_switch() in rcu_check_callbacks(). Though there is no harm that calls rcu_preempt_note_context_switch() in rcu_check_callbacks(), but it is waste. rcu_check_callbacks() rcu_sched_q... 28 Mar 2010 23:21
[PATCH 25/31] 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 ... 28 Mar 2010 23:21
