commit c8c81458863ab686cda4fe1e603fccaae0f12460 upstream.
Commit:
010c4a461c1d ("x86/speculation: Simplify and make CALL_NOSPEC consistent")
added an #ifdef CONFIG_RETPOLINE around the CALL_NOSPEC definition. This is
not required as this code is already under a larger #ifdef.
Remove the extra #ifdef, no functional change.
vmlinux size remains same before and after this change:
CONFIG_RETPOLINE=y:
text data bss dec hex filename
25434752 7342290 2301212 35078254 217406e vmlinux.before
25434752 7342290 2301212 35078254 217406e vmlinux.after
# CONFIG_RETPOLINE is not set:
text data bss dec hex filename
22943094 6214994 1550152 30708240 1d49210 vmlinux.before
22943094 6214994 1550152 30708240 1d49210 vmlinux.after

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.
