task_stack, x86/cea: Force-inline stack helpers
Force-inline two stack helpers to fix the following objtool warnings:
vmlinux.o: warning: objtool: in_task_stack()+0xc: call to task_stack_page() leaves .noinstr.text section
vmlinux.o: warning: objtool: in_entry_stack()+0x10: call to cpu_entry_stack() leaves .noinstr.text section
