Back in the day a lot of logic was implemented inline in dma-mapping.h and
needed various includes. Move of this has long been moved out of line,
so we can drop various includes to improve kernel rebuild times.

Adds a new format for MODVERSIONS which stores each field in a separate
ELF section. This initially adds support for variable length names, but
could later be used to add additional fields to MODVERSIONS in a
backwards compatible way if needed. Any new fields will be ignored by
old user tooling, un
Generate both the existing modversions format and the new extended one
when running modpost. Presence of this metadata in the final .ko is
guarded by CONFIG_EXTENDED_MODVERSIONS.
We no longer generate an error on long symbols in modpost if
CONFIG_EXTENDED_MODVERSIONS is set, as they can now be app
From: Sami Tolvanen
Previously, two things stopped Rust from using MODVERSIONS:
1. Rust symbols are occasionally too long to be represented in the
original versions table
2. Rust types cannot be properly hashed by the existing genksyms
approach because:

Due to the hardware limitation, sometimes it could sample kernel address
while attr.exclude_kernel is set. In that case it silently drops the
sample. Let's count that case in the new dropped_samples counter.

They are the prefered way to copy ethtool strings.
Avoids manually incrementing the data pointer.
