s390: opt into HAVE_COPY_THREAD_TLS

Browse source

This the s390 version of commit c1bd55f922 ("x86: opt into
HAVE_COPY_THREAD_TLS, for both 32-bit and 64-bit").

Simply use the tls system call argument instead of extracting the tls
argument by magic from the pt_regs structure.

See commit 3033f14ab7 ("clone: support passing tls argument via C
rather than pt_regs magic") for more background.
