Subject: [PATCH v3 3/4] elf: Remove has_interp property from arch_adjust_elf_prot()
Date: Mon, 14 Jun 2021 23:32:13 +0100 [thread overview]
Message-ID: <20210614223214.39011-4-broonie@kernel.org> (raw)
In-Reply-To: <20210614223214.39011-1-broonie@kernel.org>
Since we have added an is_interp flag to arch_parse_elf_property() we can
drop the has_interp flag from arch_elf_adjust_prot(), the only user was
the arm64 code which no longer needs it and any future users will be able
to use arch_parse_elf_properties() to determine if an interpreter is in
use.
