Commit: 42af417607a03bdb847d8a0ad1878f82d5b92410
Gitweb: https://git.linux-mips.org/g/ralf/linux/42af417607a0
Branch: master

If the paravirt machine is compiles without CONFIG_SMP, the following
linker error occurs

arch/mips/kernel/head.o: In function `kernel_entry':
(.ref.text+0x10): undefined reference to `smp_bootstrap'

due to the kernel entry macro always including SMP startup code.
Wrap this code in CONFIG_SMP to fix the error.
