The following call in ipa_validate_build() is erroneous:
BUILD_BUG_ON(sizeof(struct gsi_trans) > 128);
The fact is, it is not a bug for the size of a GSI transaction to be
bigger than 128 bytes. The correct operation of the driver is not
dependent on the size of this structure. The only consequence of
the transaction being large is that the amount of memory required
is larger.
The problem this was trying to flag is that a *slight* increase in
the size of this structure will have a disproportionate effect on
the amount of memory used. E.g. if the structure grew to 132 bytes
the memory requirement for the transaction arrays would be about
double.
With various debugging build flags enabled, the size grows to 160
bytes. But there's no reason to treat that as a build-time bug.

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.
