Re: [PATCH] powerpc/fsl_booke: avoid creating duplicate tlb1 entry

In the current implementation, the call to loadcam_multi() is wrapped between switch_to_as1() and restore_to_as0() calls so, when it tries to create its own temporary AS=3D1 TLB1 entry, it ends up duplicating the existing one created by switch_to_as1(). Add a check to skip creating the temporary entry if already running in AS=3D1.

Applied to powerpc next, thanks.
