#     powerpc/powermac: Fix low_sleep_handler with CONFIG_VMAP_STACK
#     
#     low_sleep_handler() can't restore the context from standard
#     stack because the stack can hardly be accessed with MMU OFF.
#     
#     Store everything in a global storage area instead of storing
#     a pointer to the stack in that global storage area.
#     
#     To avoid a complete churn of the function, still use r1 as
#     the pointer to the storage area during restore.
#     
#     Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK")
