[PATCH] x86-64: modpost add more symbols to whitelist pattern2 

o MODPOST generates warning for i386 if compiled with CONFIG_RELOCATABLE=y
  and serial console support is enabled.

o Serial console setup function, serial8250_console_setup(), is a non __init
  function and it calls functions which are of type __init().
  (uart_parse_options() and uart_set_options()). Assuming, setup will
  be called during init time, changing serial8250_console_setup() to __init.

o Adding one more pattern to modpost whitelist. Console drivers might
  have *_console structures containing references to setup functions which
  can be of __init type. Don't generate warnings for those.

WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'serial8250_console' (at offset 0xc05a33d8) and 'serial8250_reg'
