Linux kernel source tree
6c16000166
In svm_migrate_gart_map(), while migrating GART mapping, the number of bytes copied for the GART table only accounts for CPU pages. On non-4K systems, each CPU page can contain multiple GPU pages, and the GART requires one 8-byte PTE per GPU page. As a result, an incorrect size was passed to the DMA, causing only a partial update of the GART table. Fix this function to work correctly on non-4K page-size systems by accounting for the number of GPU pages per CPU page when calculating the number of bytes to be copied.

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 reStructuredText 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.
