Subject: [PATCH 1/4] mach-snapdragon: Carve out reserved memory at init for MSM8917
Date: Thu, 10 Sep 2026 09:41:44 +0000 [thread overview]
Message-ID: <20260910095339.110427-2-imkyufie@gmail.com> (raw)
In-Reply-To: <20260910095339.110427-1-imkyufie@gmail.com>
Certain regions of memory in MSM8917 are marked as 'no-map'. These
regions may cause security violation when included in the standard mapping.
