Re: [PATCH 0/63] Basic scheduler support for automatic NUMA balancing V9

2013-10-09 Thread Ingo Molnar
I started bisecting the crash, and the good news is that it's bisectable and it's not the NUMA bits that are causing the crash. (the bad news is that I now face a boring, possibly very long bisection, but hey ;-) Thanks, Ingo -- To unsubscribe from this list: send the line

[PATCH V1] Fix Regmap Block Write single-rw Mutex Deadlock

2013-10-09 Thread Anthony Olech
This patch is relative to linux-next repository tag next-20130927 When regmap_bulk_write() is called with the map->use_single_rw flag set an immediate mutex deadlock happens because regmap_raw_write() is called after obtaining the mutex and regmap_raw_write() itself then tries to obtain the mutex
