RAS/CEC: Rename count_threshold to action_threshold
... which is the better, more-fitting name anyway. Tony: - make action_threshold u64 due to debugfs accessors expecting u64. - rename the remaining: s/count_threshold/action_threshold/g Co-developed-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: linux-edac <linux-edac@vger.kernel.org>
