Merge remote branch 'origin' into secretlab/next-devicetree
Merging in current state of Linus' tree to deal with merge conflicts and build failures in vio.c after merge. Conflicts: drivers/i2c/busses/i2c-cpm.c drivers/i2c/busses/i2c-mpc.c drivers/net/gianfar.c Also fixed up one line in arch/powerpc/kernel/vio.c to use the correct node pointer.

433 Say Y here to enable the tosa keyboard driver to generate extended
434 (>= 127) keycodes. Be aware, that they can't be correctly interpreted
435 by either console keyboard driver or by Kdrive keybd driver.
436
437 Say Y only if you know, what you are doing!

15 * and data. Due to strict timing requirements of the interface,
16 * the serial data stream is read and processed by a FIQ handler.
17 * The resulting words are fetched by this driver from a circular buffer.
18 *
19 * Standard AT keyboard driver (atkbd) is used for handling the keyboard data.
20 * However, when used with the E3 mailboard that producecs non-standard
21 * scancodes, a custom key table must be prepared and loaded from userspace.
