[PATCH] sched: print module list in the "scheduling while atomic" warning

[Arjan van de Ven <arjan@infradead.org>]

Subject: [PATCH] sched: print module list in the "scheduling while atomic" warning

For the normal WARN_ON() etc we added a print-the-modules-list already,
which is very useful to figure out candidates for certain types of bugs.

This patch adds the same print to the "scheduling while atomic" BUG warning,
for the same reason: when we get here it's very useful to see which modules
are loaded, to narrow down the candidate code list.
