From 397d1533b6cce0ccb5379542e2e6d079f6936c46 Mon Sep 17 00:00:00 2001 From: David S. Miller Date: Tue, 1 Mar 2016 00:25:32 -0500 Subject: sparc64: Fix sparc64_set_context stack handling. Like a signal return, we should use synchronize_user_stack() rather than flush_user_windows(). Reported-by: Ilya Malakhov Signed-off-by: David S.
