└─>ARM errata: FSR write bit incorrect on a SWP to read-only memory
In linux kernel since version 3.1 (release Date: 2011-10-24)
Executing a SWP instruction to read-only memory does not set bit 11
of the FSR on the ARM 1136 prior to r1p0. This causes the kernel to
treat the access as a read, preventing a COW from occurring and
causing the faulting task to livelock.
