Subject: [PATCH 1/4] arm64: relocate: Let __relocate_new_kernel_start align on SZ_4K
Date: Thu, 28 Mar 2024 19:56:51 +0800 [thread overview]
Message-ID: <20240328115656.24090-2-piliu@redhat.com> (raw)
In-Reply-To: <20240328115656.24090-1-piliu@redhat.com>
For upcoming C implement, let this section align on SZ_4K, so that
it makes potential instruction pairs 'adrp, add' work.
