My recent commite5d00aaac6("selftests/powerpc: Check all FPRs in fpu_preempt") inadvertently broke the fpu_signal test. It needs to take into account that fpu_preempt now loads 32 FPRs, so enlarge darray. Also use the newly added randomise_darray() to properly randomise darray. Finally the checking done in signal_fpu_sig() needs to skip checking f30/f31, because they are used as scratch registers in check_all_fprs(), called by preempt_fpu(), and so could hold other values when the signal is taken.

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.
