#     powerpc/32s: Disable VMAP stack which CONFIG_ADB_PMU
#     
#     low_sleep_handler() can't restore the context from virtual
#     stack because the stack can hardly be accessed with MMU OFF.
#     
#     For now, disable VMAP stack when CONFIG_ADB_PMU is selected.
#     
#     Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK")
