The icp-opal call is missing the code from icp-native to recover
interrupts snatched by KVM. Without that, when running KVM, we can
get into a situation where an interrupt is lost and the CPU stuck
with an elevated CPPR.
Also harden replay by always checking the return from opal_int_eoi

Hi,
I was debugging a hang on a ppc64le kernel built with clang, and it
looks to be undefined behaviour with pointer wrapping in the llist code.
A test case is below. llist_for_each_entry() does container_of() on a
NULL pointer, which wraps our pointer negative, then adds the same
offset back in

dmaengine_prep_dma_cyclic(), it uses either DMA_TO_DEVICE or

not of dma_data_direction enum, which is the type expected by
dmaengine_prep_dma_cyclic().

Declare ipmi_smi_handlers structures as const as they are only passed as
an argument to the function ipmi_register_smi. This argument is of type
const, so ipmi_smi_handlers structures having similar properties can be
