Christophe Leroy 45f7091aac powerpc/64: Set default CPU in Kconfig 
Since commit 0069f3d14e ("powerpc/64e: Tie PPC_BOOK3E_64 to
PPC_E500MC"), the only possible BOOK3E/64 are E500, so no need of a
default CPU over the E5500.

When the user selects book3e, they must have an e500 compatible
compiler, and it won't work anymore with the default -mcpu=power64, see
commit d6b551b8f9 ("powerpc/64e: Fix build failure with GCC
12 (unrecognized opcode: `wrteei')").

For book3s/64, replace GENERIC_CPU by POWERPC64_CPU to match the PPC32
POWERPC_CPU, and set a default mpcu value in Kconfig directly.

When a user selects a particular CPU, they must ensure the compiler has
the requested capability. Therefore, remove hidden fallback, instead
offer user the possibility to say they want to use the toolchain
default.

Fixes: d6b551b8f9 ("powerpc/64e: Fix build failure with GCC 12 (unrecognized opcode: `wrteei')")

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.
