X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8b9232141bf40788cce31f893c13f344ec31ee66;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git MIPS: Rewrite pfn_valid to work in modules, too. This fixes: MODPOST 393 modules ERROR: "min_low_pfn" [arch/mips/kvm/kvm.ko] undefined! make[3]: *** [__modpost] Error 1 It would have been possible to just export min_low_pfn but in the end pfn_valid should return 1 for any pfn argument for which a struct page exists so using min_low_pfn was wrong anyway.
