+15. The whole point of call_rcu(), synchronize_rcu(), and friends
+ is to wait until all pre-existing readers have finished before
+ carrying out some otherwise-destructive operation. It is
+ therefore critically important to -first- remove any path
+ that readers can follow that could be affected by the
+ destructive operation, and -only- -then- invoke call_rcu(),
+ synchronize_rcu(), or friends.
+
+ Because these primitives only wait for pre-existing readers,
+ it is the caller's responsibility to guarantee safety to
+ any subsequent readers.

+
+ 0
+ IPv6 is enabled.
+
+ This is the default value.
+
+ 1
+ IPv6 is disabled.
+
+ No IPv6 addresses will be added to interfaces, and

+ * Within SMC chip select address space, lines A[23:21] distinguish Compact
+ * Flash modes (I/O, common memory, attribute memory, True IDE). IDE modes are:
+ * 0x00c0000 - True IDE
+ * 0x00e0000 - Alternate True IDE (Alt Status Register)
+ *
+ * On True IDE mode Task File and Data Register are mapped at the same address.
+ * To distinguish access between these two different bus data width is used:
+ * 8Bit for Task File, 16Bit for Data I/O.
+ *
+ * After initialization we do 8/16 bit flipping (changes in SMC MODE register)
+ * only inside IDE callback routines which are serialized by IDE layer,
