[Qemu-devel] [PATCH 2/9] linux-user: Add is_write segfault check for ARM hosts

2013-07-05 Thread Alexander Graf
When we get a segmentation fault we check whether the fault was a write. If it was a write, it might be a fault because we tried to modify a code region. This logic does not work on ARM hosts, because they don't evaluate whether a segementation fault is due to a write. Instead they always declare
