Subject: [PATCH 4.14 40/59] powerpc: Remove STRICT_KERNEL_RWX incompatibility with RELOCATABLE
Date: Tue, 26 May 2020 20:53:25 +0200 [thread overview]
Message-ID: <20200526183920.239637537@linuxfoundation.org> (raw)
In-Reply-To: <20200526183907.123822792@linuxfoundation.org>
From: Russell Currey <ruscur@russell.cc>
[ Upstream commit c55d7b5e64265fdca45c85b639013e770bde2d0e ]
I have tested this with the Radix MMU and everything seems to work, and
the previous patch for Hash seems to fix everything too.
STRICT_KERNEL_RWX should still be disabled by default for now.
Please test STRICT_KERNEL_RWX + RELOCATABLE!
