Patch "asm-generic/bitops/lock.h: Rewrite using atomic_fetch_" causes kernel crash

2018-08-29 Thread Eugeniy Paltsev
Hi Guys, Since v4.19-rc1 we are getting a serious regression on platforms with ARC architecture. The kernel have become unstable and spontaneously crashes on LTP tests execution / IO tests or even on boot. I don't know exactly what breaks but bisect clearly assign the blame to this commit: 84c6
