Subject: [PATCH] arm64: Drop do_el0_ia_bp_hardening() & do_sp_pc_abort() declarations
Date: Mon, 27 Jan 2020 15:19:35 +0530	[thread overview]
Message-ID: <1580118575-1705-1-git-send-email-anshuman.khandual@arm.com> (raw)

There is a redundant do_sp_pc_abort() declaration in exceptions.h which can
be removed. Also do_el0_ia_bp_hardening() as been already been dropped with
the commit bfe298745afc ("arm64: entry-common: don't touch daif before
bp-hardening") and hence does not need a declaration any more. This should
not introduce any functional change.
