To follow the existing per-arch conventions, using "current_stack_pointer"
to set sp.
This will let it be used in non-arch places(like HARDENED_USERCOPY).
Refer to the implementation of riscv commit fdecfea093 ("riscv: Rename
"sp_in_global" to "current_stack_pointer"").

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.
