Commit:c5bedc6847("x86/fpu: Get rid of PF_USED_MATH usage, convert it to fpu->fpstate_active") introduced the 'fpu' variable at top of __restore_xstate_sig(), which now shadows the other definition: arch/x86/kernel/fpu/signal.c:318:28: warning: symbol 'fpu' shadows an earlier one arch/x86/kernel/fpu/signal.c:271:20: originally declared here Remove the shadowed definition of 'fpu', as the two definitions are the same.

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.
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.
