+Subject: alpha: replace hardcoded stack offsets with autogenerated ones
+
+From: Ivan Kokshaysky <ink@unseen.parts>
+
+commit 77b823fa619f97d16409ca37ad4f7936e28c5f83 upstream.
+
+This allows the assembly in entry.S to automatically keep in sync with
+changes in the stack layout (struct pt_regs and struct switch_stack).
