The two symbols thread_excp_vect and thread_excp_vect_end are used to
mark the part of the privileged code that still to be mapped in order to
transition between user mode and privileged mode when compiled with
CFG_CORE_UNMAP_CORE_AT_EL0=y.
Prior to this patch it was assumed that thread_excp_vect_end would mark
the end of the thread_excp_vect() assembly function including literals
emitted by the assembler. This assumption was wrong and an extra .pool
directive is added before the thread_excp_vect_end to guarantee that all
literals will be included in the section starting with thread_excp_vect
and ending with thread_excp_vect_end.
