Clean up and simplify the X86 NR_CPUS Kconfig symbol/option by introducing RANGE_BEGIN_CPUS, RANGE_END_CPUS, and DEF_CONFIG_CPUS. Then combine some default values when their conditionals can be reduced. Also move the X86_BIGSMP kconfig option inside an "if X86_32"/"endif" config block and drop its explicit "depends on X86_32". Combine the max. 8192 cases of RANGE_END_CPUS (X86_64 only). Split RANGE_END_CPUS and DEF_CONFIG_CPUS into separate cases for X86_32 and X86_64.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
