-Subject: [PATCH 2/3] Allow stack to grow up to address space limit
-
-commit bd726c90b6b8ce87602208701b208a208e6d5600 upstream.
-
-Fix expand_upwards() on architectures with an upward-growing stack (parisc,
-metag and partly IA-64) to allow the stack to reliably grow exactly up to
-the address space limit given by TASK_SIZE.
