    [IA64] perfmon: make pfm_sysctl a global, and other cleanup · 4944930a
    Stephane Eranian authored
    - make pfm_sysctl a global such that it is possible
      to enable/disable debug printk in sampling formats
      using PFM_DEBUG.
    
    - remove unused pfm_debug_var variable
    
    - fix a bug in pfm_handle_work where an BUG_ON() could
      be triggered. There is a path where pfm_handle_work()
      can be called with interrupts enabled, i.e., when
      TIF_NEED_RESCHED is set. The fix correct the masking
      and unmasking of interrupts in pfm_handle_work() such
      that we restore the interrupt mask as it was upon entry.
