Subject: [PATCH 0/2] arm64: pair of minor hardening tweaks
Date: Fri, 29 Apr 2022 15:13:45 +0200 [thread overview]
Message-ID: <20220429131347.3621090-1-ardb@kernel.org> (raw)
A couple of tweaks to the way we handle the kexec and hibernate helper
code, so that it no longer gets mapped with attributes it doesn't need.
Ard Biesheuvel (2):
arm64: lds: move special code sections out of kernel exec segment
arm64: mm: avoid writable executable mappings in kexec/hibernate code
