[linux-yocto] [PATCH 02/19] common-pc: restrict NR_CPUS to 8

[Saul Wold]

From: Bruce Ashfield <bruce.ashfield at windriver.com>

Since arch/x86/Kconfig has the following range restriction for NR_CPUS

  range 2 8 if SMP && X86_32 && !X86_BIGSMP

In a common-pc build, we are indeed X86_32 enabled, so 8 is our max
CPUs. To avoid a configuration warning, we change our default to this
range's max value
