The patch titled
Subject: init/main.c: fix misleading "This architecture does not have kernel memory protection" message
has been removed from the -mm tree. Its filename was
init-fix-misleading-this-architecture-does-not-have-kernel-memory-protection-message.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Christophe Leroy <christophe.leroy@xxxxxx>
Subject: init/main.c: fix misleading "This architecture does not have kernel memory protection" message
This message leads to thinking that memory protection is not implemented
for the said architecture, whereas absence of CONFIG_STRICT_KERNEL_RWX
only means that memory protection has not been selected at compile time.
Don't print this message when CONFIG_ARCH_HAS_STRICT_KERNEL_RWX is
selected by the architecture. Instead, print "Kernel memory protection
not selected by kernel config."
