[PATCH] single bit flip detector
In cases where we detect a single bit has been flipped, we spew the usual
slab corruption message, which users instantly think is a kernel bug. In a
lot of cases, single bit errors are down to bad memory, or other hardware
failure.
This patch adds an extra line to the slab debug messages in those cases, in
the hope that users will try memtest before they report a bug.

Single bit error detected. Possibly bad RAM. Run memtest86.
