[IA64] perfmon: make pfm_sysctl a global, and other cleanup
- 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. signed-off-by: stephane eranian <eranian@hpl.hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
