      powerpc/85xx: Load all early TLB entries at once · d9e1831a
      Scott Wood authored
      Use an AS=1 trampoline TLB entry to allow all normal TLB1 entries to
      be loaded at once.  This avoids the need to keep the translation that
      code is executing from in the same TLB entry in the final TLB
      configuration as during early boot, which in turn is helpful for
      relocatable kernels (e.g. kdump) where the kernel is not running from
      what would be the first TLB entry.
      
      On e6500, we limit map_mem_in_cams() to the primary hwthread of a
      core (the boot cpu is always considered primary, as a kdump kernel
      can be entered on any cpu).  Each TLB only needs to be set up once,
      and when we do, we don't want another thread to be running when we
      create a temporary trampoline TLB1 entry.
