ARM panda board, PREEMPT_RT_FULL

-rt3 compiled OK.  -rt4 compile fails:


mm/init-mm.c:24: error: unknown field 'lock' specified in initializer
mm/init-mm.c:24: error: unknown field 'wait_lock' specified in initializer
mm/init-mm.c:24: error: incompatible types in initialization
mm/init-mm.c:24: error: unknown field 'save_state' specified in initializer
mm/init-mm.c:24: warning: excess elements in struct initializer
mm/init-mm.c:24: warning: (near initialization for 'init_mm.context.id_lock.raw_lock')



.config is attached or use this recipe:

   make omap2plus_defconfig

   Then additional config changes:

   # this allows USB thumb drive
   # Device Drivers -> USB support -> EHCI HCD (USB 2.0) support
   CONFIG_USB_EHCI_HCD=y
   # Device Drivers -> USB support -> EHCI support for OMAP3 and later chips
   CONFIG_USB_EHCI_HCD_OMAP=y

   # ethernet device
   # Device Drivers -> Network device support -> USB Network Adapters ->
   #  Multi-purpose USB Networking Framework ->
   #  SMSC LAN95XX based USB 2.0 10/100 ethernet devices
   CONFIG_USB_NET_SMSC95XX=y

   # Kernel Features -> Preemption Model -> Fully Preemptible Kernel (RT)
