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. Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK") Cc: stable@vger.kernel.org # v5.6+ Reported-by: Giuseppe Sacco <giuseppe@sguazz.it> Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/ec96c15bfa1a7415ab604ee1c98cd45779c08be0.1598553015.git.christophe.leroy@csgroup.eu
