From: Randy Dunlap <rdunlap@infradead.org>
[ Upstream commit bf296b35489b46780b73b74ad984d06750ed5479 ]
Kernel test robot reported build errors (undefined references) that didn't make much sense. After reproducing them, there is also a Kconfig warning that is the root cause of the build errors, so fix that Kconfig problem.
Fixes this Kconfig warning: WARNING: unmet direct dependencies detected for CMA Depends on [n]: MMU [=n] Selected by [m]: - DRM_ASPEED_GFX [=m] && HAS_IOMEM [=y] && DRM [=m] && OF [=y] && (COMPILE_TEST [=y] || ARCH_ASPEED) && HAVE_DMA_CONTIGUOUS [=y]
and these dependent build errors: (.text+0x10c8c): undefined reference to `start_isolate_page_range' microblaze-linux-ld: (.text+0x10f14): undefined reference to `test_pages_isolated' microblaze-linux-ld: (.text+0x10fd0): undefined reference to `undo_isolate_page_range'
