5  * The function 'LIBUNWIND__ARCH_REG_ID' name is set according to arch
6  * name and the defination of this function is included directly from
7  * 'arch/x86/util/unwind-libunwind.c', to make sure that this function
8  * is defined no matter what arch the host is.
9  *
10  * Finally, the arch specific unwind methods are exported which will
11  * be assigned to each x86 thread.
