ARM_64_LPAE_S2_TCR_RES1 is intended to map to bit 31 of the VTCR register, which is required to be set to 1 by the architecture. Unfortunately, we accidentally treat this as a signed quantity which means we also set the upper 32 bits of the VTCR to one, and they are required to be zero. Treat ARM_64_LPAE_S2_TCR_RES1 as unsigned to avoid the unwanted sign-extension up to 64 bits. Cc: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Will Deacon <will@kernel.org>
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.
