This patch converts riscv to use the generic entry infrastructure from kernel/entry/*. The generic entry makes maintainers' work easier and codes more elegant. Here are the changes than before: - More clear entry.S with handle_exception and ret_from_exception - Get rid of complex custom signal implementation - More readable syscall procedure - Little modification on ret_from_fork & ret_from_kernel_thread - Wrap with irqentry_enter/exit and syscall_enter/exit_from_user_mode - Use the standard preemption code instead of custom Signed-off-by: Guo Ren <guoren@linux.alibaba.com> Signed-off-by: Guo Ren <guoren@kernel.org> Suggested-by: Huacai Chen <chenhuacai@kernel.org>
