+Subject: [PATCH] s390x: fix fpreg_t and remove unused per_struct
+
+Including sys/procfs.h complains unknown type name 'fpreg_t' in
+bits/user.h. fpreg_t in bits/signal.h and elf_fpreg_t in bits/user.h
+are practically the same.
+
+per_struct is never used, even conflicts with kernel header
+asm/ptrace.h
