If a stack slot does not hold a spilled register (STACK_SPILL), then each of its eight bytes could potentially have a different slot_type. This information can be important for debugging, and previously we either did not print anything for the stack slot, or just printed fp-X=0 in the case where its first byte was STACK_ZERO. Instead, print eight characters with either 0 (STACK_ZERO), m (STACK_MISC) or ? (STACK_INVALID) for any stack slot which is neither STACK_SPILL nor entirely STACK_INVALID.

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.
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.
