[linux-next:master 12990/13166] arch/riscv/kernel/crash_core.c:8:27: error: 'VA_BITS' undeclared

[kernel test robot <lkp@intel.com>]

Hi Eric,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head:   1c6f93977947dbba1fc4d250c4eb8a7d4cfdecf1
commit: 8d14224263d97d0d53061cf08c2fa911418b1b7f [12990/13166] riscv/kexec: refactor for kernel/Kconfig.kexec
config: riscv-randconfig-r014-20230704 (https://download.01.org/0day-ci/archive/20230705/202307050034.tAJSN9qy-lkp@intel.com/config)
compiler: riscv64-linux-gcc (GCC) 12.3.0
reproduce: (https://download.01.org/0day-ci/archive/20230705/202307050034.tAJSN9qy-lkp@intel.com/reproduce)

If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <lkp@intel.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202307050034.tAJSN9qy-lkp@intel.com/

Note: the linux-next/master HEAD 1c6f93977947dbba1fc4d250c4eb8a7d4cfdecf1 builds fine.
      It may have been fixed somewhere.
