 #ifdef CONFIG_PROC_VMCORE
 /*
- * This function is used in two contexts:
- * - the kdump kernel has to check whether a pfn of the crashed kernel
- *   was a ballooned page. vmcore is using this function to decide
- *   whether to access a pfn of the crashed kernel.
- * - the kexec kernel has to check whether a pfn was ballooned by the
- *   previous kernel. If the pfn is ballooned, handle it properly.
+ * The kdump kernel has to check whether a pfn of the crashed kernel
+ * was a ballooned page. vmcore is using this function to decide
+ * whether to access a pfn of the crashed kernel.
  * Returns 0 if the pfn is not backed by a RAM page, the caller may
  * handle the pfn special in this case.
