Subject: [PATCH 4.19 78/90] arm64: ssbd: explicitly depend on <linux/prctl.h>

From: Anisse Astier <aastier@...ebox.fr>

commit adeaa21a4b6954e878f3f7d1c5659ed9c1fe567a upstream.

Fix ssbd.c which depends implicitly on asm/ptrace.h including
linux/prctl.h (through for example linux/compat.h, then linux/time.h,
linux/seqlock.h, linux/spinlock.h and linux/irqflags.h), and uses
PR_SPEC* defines.

This is an issue since we'll soon be removing the include from
asm/ptrace.h.
