Randy Dunlap a93a58bae9 mips: BCM63XX: ensure that CPU_SUPPORTS_32BIT_KERNEL is set
[ Upstream commit 5eeaafc8d69373c095e461bdb39e5c9b62228ac5 ]

Several header files need info on CONFIG_32BIT or CONFIG_64BIT,
but kconfig symbol BCM63XX does not provide that info. This leads
to many build errors, e.g.:

   arch/mips/include/asm/page.h:196:13: error: use of undeclared identifier 'CAC_BASE'
           return x - PAGE_OFFSET + PHYS_OFFSET;
   arch/mips/include/asm/mach-generic/spaces.h:91:23: note: expanded from macro 'PAGE_OFFSET'
   #define PAGE_OFFSET             (CAC_BASE + PHYS_OFFSET)
   arch/mips/include/asm/io.h:134:28: error: use of undeclared identifier 'CAC_BASE'
           return (void *)(address + PAGE_OFFSET - PHYS_OFFSET);
   arch/mips/include/asm/mach-generic/spaces.h:91:23: note: expanded from macro 'PAGE_OFFSET'
   #define PAGE_OFFSET             (CAC_BASE + PHYS_OFFSET)

arch/mips/include/asm/uaccess.h:82:10: error: use of undeclared identifier '__UA_LIMIT'
           return (__UA_LIMIT & (addr | (addr + size) | __ua_size(size))) == 0;

Selecting the SYS_HAS_CPU_BMIPS* symbols causes SYS_HAS_CPU_BMIPS to be
set, which then selects CPU_SUPPORT_32BIT_KERNEL, which causes
CONFIG_32BIT to be set. (a bit more indirect than v1 [RFC].)

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 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.
