[PATCH kernel v2] powerpc/mm: Flush radix process translations when setting MMU type

Radix guests do normally invalidate process-scoped translations when a new pid is allocated but migrated guests do not invalidate these so migrated guests crash sometime, especially easy to reproduce with migration happening within first 10 seconds after the guest boot start on the same machine.

[PATCH] KVM: PPC: Fix svcpu copying with preemption enabled

When copying between the vcpu and svcpu, we may get scheduled away onto a different host CPU which in turn means our svcpu pointer may change. That means we need to atomically copy to and from the svcpu with preemption disabled, so that all code around it always sees a coherent state.

The recent TLB flush rework broke the build when the Radix MMU is disabled at build time, eg: (.text+0x264): undefined reference to `.radix__tlbiel_all' We could add an empty version, but if we ever called it by accident that would indicate a bad bug, so add a stub that just WARNs if we do.

Hi, yesterday I recompiled the kernel on my late 2005 G4 PowerBook, and the Wifi stopped working. After comparing the configuration is turns out that a change to a Kconfig condition disabled SSB support which is necessary for these chips. The graph of configuration options is quite
