ARCv2 ISA_CONFIG and ARC700_BUILD build config registers are not compatible. cpuinfo_arc had isa info placeholder which was mashup of bits form both. Untangle this by defining it off of ARCv2 ISA info and it is fine even for ARC700 since former is a super set of latter (ARC700 buildonly has 2 bits for atomics and stack check). At runtime, we treat ARCv2 ISA info as a generic placeholder but populate it correctly depending on ARC700 or HS. This paves way for adding more HS specific bits in isa info which was colliding with the extra bits for arc700. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
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.
