Subject: sh: Disable unaligned kernel access printks by default.
X-Git-Tag: firefly_0821_release~12167^2~8
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8406638ab041b3f1ab3d49d6fe1989e25f3ffcad;p=firefly-linux-kernel-4.4.55.git

sh: Disable unaligned kernel access printks by default.

Certain networking and USB workloads generate floods of these accesses,
so just disable it by default (thereby restoring the old behaviour). The
option remains configurable from userspace, and can still be used as a
debugging aid.
