bpf: Add BPF_J{LT,LE,SLT,SLE} instructions
This set adds BPF_J{LT,LE,SLT,SLE} instructions to the BPF
insn set, interpreter, JIT hardening code and all JITs are
also updated to support the new instructions. Basic idea is
to reduce register pressure by avoiding BPF_J{GT,GE,SGT,SGE}
rewrites. Removing the workaround for the rewrites in LLVM,
this can result in shorter BPF programs, less stack usage
and less verification complexity. First patch provides some
more details on rationale and integration.
Thanks a lot!

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.
