It's not needed because it can be calculated from the Interrupt Pending Buffer (IPB), which is saved and restored. The PIPR must therefore always be recomputed when pushing an OS context. This patch fixes a path on P9 and P10 where it was not done. If there was a pending interrupt when the OS context was pulled, the IPB was saved correctly. When pushing back the context, the code in xive_tctx_need_resend() was checking for a interrupt raised while the context was not on the CPU, saved in the NVT. If one was found, then it was merged with the saved IPB and the PIPR updated and everything was fine. However, if there was no interrupt found in the NVT, then xive_tctx_ipb_update() was not being called and the PIPR was not updated. This patch fixes it by always calling xive_tctx_ipb_update(). Note that on P10 (xive2.c) and because of the above, there's no longer any need to check the CPPR value so it can go away.

Otherwise, we can end up catching the External interrupt exception in hypervisor mode, which is unexpected. The problem is best illustrated with the following scenario: 1. an External interrupt is raised while the guest is on the CPU. 2. before the guest can ack the External interrupt, an hypervisor interrupt is raised, for example the Hypervisor Decrementer or Hypervisor Virtualization interrupt. The hypervisor interrupt forces the guest to exit while the External interrupt is still pending. 3. the hypervisor handles the hypervisor interrupt. At this point, the External interrupt is still pending. So it's very likely to be delivered while the hypervisor is running. That's unexpected and can result in an infinite loop where the hypervisor catches the External interrupt, looks for an interrupt in its hypervisor queue, doesn't find any, exits the interrupt handler with the External interrupt still raised, repeat... The fix is simply to always lower the External interrupt signal when pulling an OS context. It means it needs to be raised again when re-pushing the OS context. Fortunately, it's already the case, as we now always call xive_tctx_ipb_update(), which will raise the signal if needed.
