Benjamin Herrenschmidt 14d4ae5c4c powerpc: Add optional smp_ops->prepare_cpu SMP callback ... Some platforms (will) need to perform allocations before bringing a new CPU online. Doing it from smp_ops->setup_cpu is the wrong thing to do: - It has no useful failure path (too late) - Calling any allocator will enable interrupts prematurely causing problems with large decrementer among others Instead, add a new callback that is called from __cpu_up (so from the context trying to online the new CPU) at a point where we can safely allocate and handle failures. This will be used by XIVE support. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>		2017-04-06 19:58:53 +10:00
