It's a common pattern in cpuid leaves to have the same bitfields format
repeated across a number of subleaves. Typically, this is used for
enumerating hierarchial structures like cache and TLB levels, CPU
topology levels, etc.
Modify kcpuid.c to handle subleaf ranges in the CSV file subleaves
column. For example, make it able to parse lines in the form:
# LEAF, SUBLEAVES, reg, bits, short_name , ...
0xb, 1:0, eax, 4:0, x2apic_id_shift , ...
0xb, 1:0, ebx, 15:0, domain_lcpus_count , ...
0xb, 1:0, ecx, 7:0, domain_nr , ...
This way, full output can be printed to the user.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
