6.1-stable review patch. If anyone has any objections, please let me know.

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).
