  "cacheinfo and arch_topology updates for v6.3

   The main change is to build the cache topology information for all
   the CPUs from the primary CPU. Currently the cacheinfo for secondary CPUs
   is created during the early boot on the respective CPU itself. Preemption
   and interrupts are disabled at this stage. On PREEMPT_RT kernels, allocating
   memory and even parsing the PPTT table for ACPI based systems triggers a:
     'BUG: sleeping function called from invalid context'

   To prevent this bug, the cacheinfo is now allocated from the primary CPU
   when preemption and interrupts are enabled and before booting secondary
   CPUs. The cache levels/leaves are computed from DT/ACPI PPTT information
   only, without relying on any architecture specific mechanism if done so
   early.

   The other minor change included here is to handle shared caches at
   different levels when not all the CPUs on the system have the same
   cache hierarchy."
