Use __free_reserved_page() to simplify the code in arch. It used split_page() in consistent_alloc()/__dma_alloc_coherent()/dma_alloc_coherent(), so page->_count == 1, and we can free it safely. __free_reserved_page() ClearPageReserved() init_page_count() // it won't change the v

[PATCH] powerpc: default arch idle could cede processor on pseries

2013-09-04 Thread Vaidyanathan Srinivasan
Hi, Idle routines on pseries were rearranged so that cpuidle can do an optimized idle state selection. However, until cpuidle takes over during boot, the idle loop spins for a short while. This actually affected bootup time since spinning idle sibling threads slows down master cpu that executes
