Ard Biesheuvel c82ceb440b efi/libstub: use EFI provided memcpy/memset routines ... The stub is used in different execution environments, but on arm64, RISC-V and LoongArch, we still use the core kernel's implementation of memcpy and memset, as they are just a branch instruction away, and can generally be reused even from code such as the EFI stub that runs in a completely different address space. KAsan complicates this slightly, resulting in the need for some hacks to expose the uninstrumented, __ prefixed versions as the normal ones, as the latter are instrumented to include the KAsan checks, which only work in the core kernel. Unfortunately, #define'ing memcpy to __memcpy when building C code does not guarantee that no explicit memcpy() calls will be emitted. And with the upcoming zboot support, which consists of a separate binary which therefore needs its own implementation of memcpy/memset anyway, it's better to provide one explicitly instead of linking to the existing one. Given that EFI exposes implementations of memmove() and memset() via the boot services table, let's wire those up in the appropriate way, and drop the references to the core kernel ones.
