  LoongArch/crypto: Clean up useless assignment operations (2024-03-19 15:50:34 +0800)

----------------------------------------------------------------
LoongArch changes for v6.9

1, Add objtool support for LoongArch;

4, Select ARCH_HAS_CURRENT_STACK_POINTER in Kconfig;
5, Select HAVE_ARCH_USERFAULTFD_MINOR in Kconfig;
