 1) Interrupt client nodes
 -------------------------
 
-Nodes that describe devices which generate interrupts must contain an either an
-"interrupts" property or an "interrupts-extended" property. These properties
-contain a list of interrupt specifiers, one per output interrupt. The format of
-the interrupt specifier is determined by the interrupt controller to which the
-interrupts are routed; see section 2 below for details.
+Nodes that describe devices which generate interrupts must contain an
+"interrupts" property, an "interrupts-extended" property, or both. If both are
+present, the latter should take precedence; the former may be provided simply
+for compatibility with software that does not recognize the latter. These
+properties contain a list of interrupt specifiers, one per output interrupt. The
+format of the interrupt specifier is determined by the interrupt controller to
+which the interrupts are routed; see section 2 below for details.
 
   Example:
 	interrupt-parent = <&intc1>;

 profiles.  If you believe that individual invalidations being
 called too often, you can lower the tunable:
 
-	/sys/debug/kernel/x86/tlb_single_page_flush_ceiling
+	/sys/kernel/debug/x86/tlb_single_page_flush_ceiling
 
 This will cause us to do the global flush for more cases.
 Lowering it to 0 will disable the use of the individual flushes.
