If ITT only contains invalid entries, vgic_its_restore_itt returns 1 and this is considered as an an error in vgic_its_restore_dte. Also in case the device table only contains invalid entries, the table restore fails and this is not correct. This patch fixes those 2 issues: - vgic_its_restore_itt now returns <= 0 values. If all ITEs are invalid, this is considered as successful. - vgic_its_restore_device_tables also returns <= 0 values. We also simplify the returned value computation in handle_l1_dte.

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.
