Linus Torvalds 5cd2217774 Fix CC_HAS_ASM_GOTO_OUTPUT on non-x86 architectures 
[ Upstream commit fde0ab43b9 ]

There's a silly problem with the CC_HAS_ASM_GOTO_OUTPUT test: even with
a working compiler it will fail on some architectures simply because it
uses the mnemonic "jmp" for testing the inline asm.

And as reported by Geert, not all architectures use that mnemonic, so
the test fails spuriously on such platforms (including arm and riscv,
but also several other architectures).

This issue avoided any obvious test failures because the build still
works thanks to falling back on the old non-asm-goto code, which just
generates worse code.

Just use an empty asm statement instead.

README 

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 reStructuredText 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.
