Subject[patch 36/49] uml: stub needs to tolerate SIGWINCH
2.6.25-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Jeff Dike <jdike@addtoit.com>

commit 3d5ede6f776bdb1483bcd086f79c3bf41fed3865 upstream

We lost the marking of SIGWINCH as being OK to receive during stub
execution, causing a panic should that happen.
