 Modules changes for v6.10-rc1
 
 Finally something fun. Mike Rapoport does some cleanup to allow us to
 take out module_alloc() out of modules into a new paint shedded execmem_alloc()
 and execmem_free() so to make emphasis these helpers are actually used outside
 of modules. It starts with a no-functional changes API rename / placeholders
 to then allow architectures to define their requirements into a new shiny
 struct execmem_info with ranges, and requirements for those ranges. Archs
 now can intitialize this execmem_info as the last part of mm_core_init() if
 they have to diverge from the norm. Each range is a known type clearly
 articulated and spelled out in enum execmem_type.
 
 Although a lot of this is major cleanup and prep work for future enhancements an
 immediate clear gain is we get to enable KPROBES without MODULES now. That is
 ultimately what motiviated to pick this work up again, now with smaller goal as
 concrete stepping stone.
 
 This has been sitting on linux-next for a little less than a month, a few issues
 were found already and fixed, in particular an odd mips boot issue. Arch folks
 reviewed the code too. This is ready for wider exposure and testing.
