Mark Johnston 8adca661c2 mpi3mr: Check for copyin errors in mpi3mr_map_data_buffer_dma()
A failed copyin will cause the driver to use the contents of
uninitialized buffers instead, which is unlikely to be the behaviour
that we want.  Check for errors.

This is in preparation for annotating copyin() and related functions
with __result_use_check.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
