commit 43a0541e31 upstream.
Both Tegra30 and Tegra114 have 4 ASID's and the corresponding bitfield of
the TLB_FLUSH register differs from later Tegra generations that have 128
ASID's.
In a result the PTE's are now flushed correctly from TLB and this fixes
problems with graphics (randomly failing tests) on Tegra30.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
