MIPS: Detect bad _PFN_SHIFT values
2 recent commits have fixed issues where _PFN_SHIFT grew too large due to the introduction of too many pgprot bits in our PTEs for some MIPS32 kernel configurations. Tracking down such issues can be tricky, so add a BUILD_BUG_ON() to help. Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: linux-mips@vger.kernel.org
