[PATCH 0/2] pseries extended cede cpu offline mode removal

[Nathan Lynch]

I propose removing the "extended cede" offline mode for CPUs as well
as the partition suspend code which accommodates it by temporarily
onlining all CPUs prior to suspending the LPAR.

Detailed justifications are within the individual commit messages.

I'm hoping to move the pseries partition suspend implementation to
the Linux suspend framework, and I expect that having only one offline
mode for CPUs will make that task quite a bit less complex.
