Hi all, This is Kexec part of the larger series[1] posted few months ago. I eliminated Kdump part in this resend (will post it as a separate entity later).
Milton Miller hinted that current PPC32 Kexec implementation may not work on SMP hardware. I don't have any multi-core machines handy to actually try and/or fix it, but support for SMP should be straightforward: just need to bring the secondary CPUs down before Kexec'ing (the code is already in the machine_kexec_64.c, just needs to be factored out). The arch/powerpc/Kconfig already states that the Kexec support is experimental and may not work on certain hardware, so I don't see any reason to add !SMP dependency. Anyway, the majority of boards are UP and they don't need any fancy care to work. So let's support them.
