Subject: [PATCH AUTOSEL 5.12 32/33] riscv: code patching only works on !XIP_KERNEL
Date: Tue, 15 Jun 2021 11:48:23 -0400 [thread overview]
Message-ID: <20210615154824.62044-32-sashal@kernel.org> (raw)
In-Reply-To: <20210615154824.62044-1-sashal@kernel.org>
From: Jisheng Zhang <jszhang@kernel.org>
[ Upstream commit 42e0e0b453bc6ead49c573ed512502069627546b ]
Some features which need code patching such as KPROBES, DYNAMIC_FTRACE
KGDB can only work on !XIP_KERNEL. Add dependencies for these features
that rely on code patching.
