      x86: properly initialize temp insn buffer for paravirt patching · d34fda4a
      Chris Wright authored
      With commit ab144f5e the patching code
      now collects the complete new instruction stream into a temp buffer
      before finally patching in the new insns.  In some cases the paravirt
      patchers will choose to leave the patch site unpatched (length mismatch,
      clobbers mismatch, etc).
      
      This causes the new patching code to copy an uninitialized temp buffer,
      i.e.  garbage, to the callsite.  Simply make sure to always initialize
      the buffer with the original instruction stream.  A better fix is to
      audit all the patchers and return proper length so that apply_paravirt()
      can skip copies when we leave the patch site untouched.
