3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 5f35b9cd553fd64415b563497d05a563c988dbd6 upstream.
Commit 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection") added
kernel stack overflow detection, however it only enabled it conditional
upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never
actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW,
which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so
switch it to using that definition instead.
Fixes: 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection")
