Revision 4a133eb351ccc275683ad49305d0b04dde903733 authored by Christophe Leroy on 27 August 2020, 18:30:27 UTC, committed by Michael Ellerman on 28 August 2020, 02:03:18 UTC
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.
