David S. Miller e3a724edee sparc64: Support cbcond instructions in eBPF JIT.
cbcond combines a compare with a branch into a single instruction.

The limitations are:

1) Only newer chips support it

2) For immediate compares we are limited to 5-bit signed immediate
   values

3) The branch displacement is limited to 10-bit signed

4) We cannot use it for JSET

Also, cbcond (unlike all other sparc control transfers) lacks a delay
slot.

Currently we don't have a useful instruction we can push into the
delay slot of normal branches.  So using cbcond pretty much always
increases code density, and is therefore a win.

README

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.
