      arm64: remove broken cachepolicy code · 26a945ca
      Mark Rutland authored
      The cachepolicy kernel parameter was intended to aid in the debugging of
      coherency issues, but it is fundamentally broken for several reasons:
      
       * On SMP platforms, only the boot CPU's tcr_el1 is altered. Secondary
         CPUs may therefore use differ w.r.t. the attributes they apply to
         MT_NORMAL memory, resulting in a loss of coherency.
      
       * The cache maintenance using flush_dcache_all (based on Set/Way
         operations) is not guaranteed to empty a given CPU's cache hierarchy
         while said CPU has caches enabled, it cannot empty the caches of
         other coherent PEs, nor is it guaranteed to flush data to the PoC
         even when caches are disabled.
      
       * The TLBs are not invalidated around the modification of MAIR_EL1 and
         TCR_EL1, as required by the architecture (as both are permitted to be
         cached in a TLB). This may result in CPUs using attributes other than
         those expected for some memory accesses, resulting in a loss of
         coherency.
      
       * Exclusive accesses are not architecturally guaranteed to function as
         expected on memory marked as Write-Through or Non-Cacheable. Thus
         changing the attributes of MT_NORMAL away from the (architecurally
         safe) defaults may cause uses of these instructions (e.g. atomics) to
         behave erratically.
      
      Given this, the cachepolicy code cannot be used for debugging purposes
      as it alone is likely to cause coherency issues. This patch removes the
      broken cachepolicy code.

      UEFI updates for arm64
      
      This series consists of a reimplementation of the virtual remapping of
      UEFI Runtime Services in a way that is stable across kexec, including
      the required preparatory refactoring and other work to set the stage,
      and some cleaning up afterwards to remove boot services memory and
      identitity map handling that has now become redundant.
