This whole chain gets inlined, # so when we free the init section (hence kvm_guest_init()), this code # goes away and hence should no longer be patched. # # We seen this as userspace memory corruption when using a memory # checker while doing partition migration testing on powervm (this # starts the code patching post migration via # /sys/kernel/mobility/migration). In theory, it could also happen when # using /sys/kernel/debug/powerpc/barrier_nospec. # # Cc: stable@vger.kernel.org # 4.13+ # Signed-off-by: Michael Neuling <mikey@neuling.org> # Reviewed-by:
