1dd088946cf464a994bc93945a360aef049493af pseries: Small cleanup to H_CEDE implementation
The H_CEDE hypercall implementation for the pseries machine doesn't trigger
quite the right path in the main cpu exec loop. We should set exit_request
to pop up one extra level and recheck state, and we should set the
exception_index to EXCP_HLT (H_CEDE is roughly equivalent to the hlt
instruction on x86).
In practice, this doesn't really matter except for KVM, and KVM implements
H_CEDE internally so we never hit this code path. But we might as well
get it right, just in case it matters some day.
