Pull misc x86 updates from Thomas Gleixner:
 "Updates for miscellaneous x86 areas:

   - Reserve a new boot loader type for barebox which is usally used on
     ARM and MIPS, but can also be utilized as EFI payload on x86 to
     provide watchdog-supervised boot up.

   - Consolidate the native and compat 32bit signal handling code and
     split the 64bit version out into a separate source file

   - Switch the ESPFIX random usage to get_random_long()"
