Major overhaul of handling of CPU/MMU/TLB specific functions. This allows different ARM CPUS with different cache architectures for example to be supported in a single kernel. - All CPU/MMU/TLB specific functions are now held as function pointers in a cpu_functions structure defined in machine/cpufunc.h All coproc 15 accesses, TLB flushing, cache cleaning/flushing and abort correction functions are now defined in this structure. - cpufuncs is a global structure that is setup during initarm() that holds all the function pointers for the booted CPU. - A global variable 'cputype' now defines the probed cputype. - All the existing functions for manipulating CPU specific features have been replaced with macros defined in machine/cpufunc.h that will call the appropriate function in the cpu_functions structure. - CPU functions are provided for selected CPU types (config options) and the appropriate cpu_functions structure is chosen during booting, based on the probed CPU type. - All the required functions for existing CPU types (ARM6, ARM7 and SA110) have been implemented.

Major overhaul of handling of CPU/MMU/TLB specific functions. This allows different ARM CPUS with different cache architectures for example to be supported in a single kernel. - All CPU/MMU/TLB specific functions are now held as function pointers in a cpu_functions structure defined in machine/cpufunc.h All coproc 15 accesses, TLB flushing, cache cleaning/flushing and abort correction functions are now defined in this structure. - cpufuncs is a global structure that is setup during initarm() that holds all the function pointers for the booted CPU. - A global variable 'cputype' now defines the probed cputype. - All the existing functions for manipulating CPU specific features have been replaced with macros defined in machine/cpufunc.h that will call the appropriate function in the cpu_functions structure. - CPU functions are provided for selected CPU types (config options) and the appropriate cpu_functions structure is chosen during booting, based on the probed CPU type. - All the required functions for existing CPU types (ARM6, ARM7 and SA110) have been implemented.
