Subject: [PATCH 4.19 01/35] ARM: 9133/1: mm: proc-macros: ensure *_tlb_fns are 4B aligned
Date: Mon, 1 Nov 2021 10:17:13 +0100 [thread overview]
Message-ID: <20211101082451.831165264@linuxfoundation.org> (raw)
In-Reply-To: <20211101082451.430720900@linuxfoundation.org>
From: Nick Desaulniers <ndesaulniers@google.com>
commit e6a0c958bdf9b2e1b57501fc9433a461f0a6aadd upstream.
A kernel built with CONFIG_THUMB2_KERNEL=y and using clang as the
assembler could generate non-naturally-aligned v7wbi_tlb_fns which
results in a boot failure. The original commit adding the macro missed
the .align directive on this data.
