[ros-diffs] [sir_richard] 45510: [ARM DDK]: Use the closest possible approximation to the x86 KPCR/KPRCB (in fact, the public KPCR is identical, just the KIPCR is different, internally), instead of a mashup of PPC and MIPS structures.

[ARM DDK]: Use the closest possible approximation to the x86 KPCR/KPRCB (in fact, the

PPC and MIPS structures.
