Currently, the SBI extension handle is expected to return Linux error code. The top SBI layer converts the Linux error code to SBI specific error code that can be returned to guest invoking the SBI calls. This model works as long as SBI error codes have 1-to-1 mappings between them. However, that may not be true always. This patch attempts to disassociate both these error codes by allowing the SBI extension implementation to return SBI specific error codes as well. The extension will continue to return the Linux error specific code which will indicate any problem *with* the extension emulation while the SBI specific error will indicate the problem *of* the emulation.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
