We've had DEBUG_INFO enabled for arm64 defconfigs since the initial commit. This is probably not that frequently used but substantially inflates the size of the build tree and amount of I/O needed during the build. This was causing issues with storage usage in some automated CI environments which don't expect defconfigs to be quite this big, and generally increases the resource consumption for both them and people doing local builds. The main use case for the debug info is decoding things with scripts/faddr2line but that doesn't need the full DEBUG_INFO, DEBUG_INFO_REDUCED is enough for it, so enable that by default.

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 Restructured Text 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.
