Separate the function symbol address from .plt to .got.plt section. The original plt entry has trampoline code with symbol address, there is a 32-bit padding bwtween jar instruction and symbol address. Extract the symbol address to .got.plt to reduce the module size.

The address of external symbols will locate more than 32-bit offset in 64-bit kernel with sv39 or sv48 virtual addressing. Module loader emits the GOT and PLT entries for data symbols and function symbols respectively. The PLT entry is a trampoline code for jumping to the 64-bit real address. The GOT entry is just the data symbol address. Signed-off-by: NZong Li <zong@andestech.com> Signed-off-by: NPalmer Dabbelt <palmer@sifive.com>
