      [IA64] Don't alloc empty frame in ia64_switch_mode_phys · e55ce456

      I think ia64_switch_mode_phys and ia64_switch_mode_virt
      does not need to alloc an empty frame.
      An empty frame is required by loadrs but flushrs
      does not need that.

      [IA64] Do not assume output registers be reservered. · acb15c85

      We found an issue in pal.S.
      
      According to the software runtime SPEC,
      The caller's output registers do not need to be preserved for
      caller. The callee may reuse input registers for any other
      purpose within the procedure.
      
      in ia64_pal_call_phys_stacked,
      
      input registers are copied to output registers before call
      into ia64_switch_mode_phys, then used to call into PAL. This
      assumes output registers are preserved in ia64_switch_mode_phys,
      which may not be true.
      
      In this particular case, ia64_switch_mode_phys alloc a null frame
      , and mask off psr.i.
      If an interrupt comes at this small window,
      or an MCA comes inside the procedure, output registers
      maybe changed,
      then the pal call may got some staled input registers.
      
      This patch moves the copies from input to output
      after ia64_switch_mode_phys to follow the software
      runtime convention.
      
      It  also removed some unused labels in
      ia64_pal_call_phys_stacked.

      [IA64] sparse cleanups · e037cda5
      Keith Owens authored
      
      
      Fix some sparse warnings on ia64.  Large constants that should be long
      instead of int.  Use NULL instead of 0.  Add some missing __iomem
      casts.  Replace a non-C99 structure assignment.
