Fix a Linux-4.3 corner case performance regression, introduced by commit:
f1ccd24931 ("x86/smpboot: Fix cpu_init_udelay=10000 corner case boot parameter misbehavior")
which allowed the cmdline "cpu_init_udelay=" to work with all values,
including the default of 10000.
But in setting the default of 10000, it over-rode the code stat sets
the delay 0 on modern processors.
Also, tidy up use of INT/UINT.
