Hi,

this change was not reviewed nor testing was thought for all
architectures it touches. The change happens to break MIPS quite
thoroughly, since MIPS is using different pointers when accessing PCPU
area locally and when doing iterations using cpu_to_cpuid array. I
therefore officially am requesting this change to be reverted until
reasonable solution is found to unbreak architectures that use wired
TLBs to access local per-CPU data.
