Hook up the generic vDSO implementation to the LoongArch vDSO data page by providing the required __arch_chacha20_blocks_nostack, __arch_get_k_vdso_rng_data, and getrandom_syscall implementations. Also wire up the selftests. Signed-off-by: Xi Ruoyao <xry111@xry111.site> Acked-by: Huacai Chen <chenhuacai@kernel.org> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
