X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=00699e8472cc0209d57b5c5614bc2ec98e665004;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

uml: fix WARNING: vmlinux: 'memcpy' exported twice

Fix the following warning on x86_64:

LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux: 'memcpy' exported twice. Previous export was in vmlinux

For x86_64, this symbol is already exported from arch/um/sys-x86_64/ksyms.c.
