But at this point, when using VMAP stack the DATA MMU # translation has already been re-enabled, leading to deadlock. # # Don't use the physical address of the stack when # CONFIG_VMAP_STACK is set. # # Signed-off-by: Christophe Leroy # Reported-by: Guenter Roeck # Fixes: 028474876f47 ("powerpc/32: prepare for CONFIG_VMAP_STACK") # Tested-by: Guenter Roeck # Signed-off-by: Michael Ellerman # Link:
