When kcpuid is invoked with "--all --details", the detailed description column is not properly aligned for all bitfield rows: CPUID_0x4_ECX[0x0]: cache_level : 0x1 - Cache Level ... cache_self_init - Cache Self Initialization This is due to differences in output handling between boolean single-bit "bitflags" and multi-bit bitfields. For the former, the bitfield's value is not outputted as it is implied to be true by just outputting the bitflag's name in its respective line. If long descriptions were requested through the --all parameter, properly align the bitflag's description columns through extra tabs. With that, the sample output above becomes: CPUID_0x4_ECX[0x0]: cache_level : 0x1 - Cache Level ... cache_self_init - Cache Self Initialization Signed-off-by: Ahmed S.

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.
