ARM v8.2 has a feature to add implicit error synchronization barriers whenever the CPU enters or returns from an exception level. Add this to the features we always enable. CPUs that don't support this feature will treat the bit as RES0. This feature causes RAS errors that are not yet visible to software to become pending SErrors. We expect to have firmware-first RAS support so synchronised RAS errors will be take immediately to EL3. Any system without firmware-first handling of errors will take the SError either immediatly after exception return, or when we unmask SError after entry.S's work. Adding IESB to the ELx flags causes it to be enabled by KVM and kexec too. Platform level RAS support may require additional firmware support.

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.
