From: "Borislav Petkov (AMD)" <bp@alien8.de>
sev-dev.c calls code in the AMD IOMMU now but that can't really work if latter is not enabled in Kconfig:
ld: vmlinux.o: in function `__sev_firmware_shutdown.isra.0': sev-dev.c:(.text+0x2501f0e): undefined reference to `amd_iommu_snp_disable' ld: vmlinux.o: in function `snp_rmptable_init': sev.c:(.init.text+0x26260): undefined reference to `amd_iommu_snp_en' make[2]: *** [scripts/Makefile.vmlinux:37: vmlinux] Error 1 make: *** [Makefile:240: __sub-make] Error 2
Fix those deps.
