Subject: [PATCH mips-next 0/2] MIPS: optimize relocations processing

This series converts the logics of two main relocation functions,
one for relocatable kernel and one for modules, from the arrays of
handlers (callbacks) to plain switch-case functions, which allows
the compiler to greatly optimize the code, so the relocations will
be applied faster with lesser code size.

Tested on MIPS32 R2 with GCC 10.2 and LLVM 11.0 with -O2.

  MIPS: module: optimize module relocations processing
  MIPS: relocatable: optimize the relocation process
