# How to handle alignment faults on the ARM
#
# 0 - ignore, the value will probably be rotated
# 1 - warn, a log message will be output
# 2 - fixup, the kernel will do an expensive aligned read
# 3 - fixup+warn
# 4 - signal, the process will get an illegal instruction fault
# 5 - signal+warn
# 6 - invalid (has no effect)
# 7 - invalid (has no effect)
#
# Set ALIGN in /etc/default/rcS to override (do not edit this
# file!) Set ALIGN to empty to avoid changing the kernel
# default (currently '0').
ALIGN=1
