      [PATCH] ia64: fix SAVE_RESET so OS INIT handler works again · 387178be
      Tony Luck authored
      The syscall optimization patches broke the OS INIT handler because
      SAVE_RESET was addressing relative to r12, which contains the virtual
      address of the stack pointer.  Fixed by addressing relative to r2/r3
      instead.

      [PATCH] ia64: performance-tweak syscall exit path some more · 76e974c7
      Fenghua Yu authored
      Please find the attached patch that:
      
      1. Moves user stack flag memory access before srlz.i;
      
      2. Moves mov b6=r22 as late as possible. 
      
      3. Changes (pSys) to (pLvSys) in skip_rbs_switch: section. IA32 syscall
      set pSys=1 but pLvSys=0. It's not necessary to clear bank1 r16-r19 registers
      for IA32 syscall.
      
      The number for leave_syscall is 268 cycles with this patch. The number
      is 295 cycles w/o this patch. It was 245 cycles with the original kee patched
      kernel. The 23 cycles come from restoring b6 operation which didn't exist in
      the orignal kee patch.
