As the data parameter is not really used by any ftrace_dyn_arch_init, remove that from ftrace_dyn_arch_init. This also removes the addr local variable from ftrace_init which is now unused. Note the documentation was imprecise as it did not suggest to set (*data) to 0.

No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any way, it just sets the value to 0. And this is used as a return value in the caller -- ftrace_init, which just checks the retval against zero. Note there is also "return 0" in every ftrace_dyn_arch_init. So it is enough to check the retval and remove all the indirect sets of data on all archs.

device_type is deprecated and the kernel doesn't require it in most cases. The only exceptions for flat tree users are the "gianfar", "ucc_geth" and "ibm,emac" bindings, and arguably that requirement could be relaxed for ucc_geth and ibm,emac (that is a task for separate patches though). This patch removes references to device_type="network" from the binding documentation where possible and removes the properties from ARM and microblaze dts files. This patch does not modify the powerpc .dts files since there are a much larger number of them affected and I think the ucc_geth, ibm,emac and gianfar users should be addressed before clearing out the references to reduce the chance of breakage.

We're going to be adding a few new barrier primitives, and in order to avoid endless duplication make more agressive use of asm-generic/barrier.h. Change the asm-generic/barrier.h such that it allows partial barrier definitions and fills out the rest with defaults. There are a few architectures (m32r, m68k) that could probably do away with their barrier.h file entirely but are kept for now due to their unconventional nop() implementation.
