Subject: tile: array underflow in setup_maxnodemem()
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f3b2148eda63b42e082259aaf1622c9ae2d53ac8;p=pandora-kernel.git

tile: array underflow in setup_maxnodemem()

commit 637f23abca87d26e091e0d6647ec878d97d2c6cd upstream.

My static checker correctly complains that we should have a lower bound
on "node" to prevent an array underflow.

Fixes: 867e359b97c9 ("arch/tile: core support for Tilera 32-bit chips.")
