+Subject: prctl: Temporarily disable prctl(PR_SET_MDWE) on parisc
+
+systemd-254 tries to use prctl(PR_SET_MDWE) for systemd's
+MemoryDenyWriteExecute functionality, but fails on PA-RISC/HPPA which
+still needs executable stacks.
+
+Temporarily disable prctl(PR_SET_MDWE) by returning -ENODEV on parisc
+for now. Note that we can't return -EINVAL since systemd will then try
+to use seccomp instead.

+The encryption is only mandatory to be enforced when both sides are using
+Secure Simple Pairing and this means the key size check makes only sense

+On legacy Bluetooth 2.0 and earlier devices like mice the encryption was

+From: Michael Weiß <michael.weiss@aisec.fraunhofer.de>
+Date: Wed, 31 Jul 2024 10:52:17 +0200
+Message-Id: <20240731085217.94928-1-michael.weiss@aisec.fraunhofer.de>

+
+Since commit ea558c86248b ("tools lib subcmd: Show parent options in
+help"), our debug images fail to build.
+
+For our Yocto-based GyroidOS, we build debug images with debugging enabled
+for all binaries including the kernel. Yocto passes the corresponding gcc
+option "-Og" also to the kernel HOSTCFLAGS. This results in the following
+build error:
+
+  parse-options.c: In function ‘options__order’:
+  parse-options.c:834:9: error: ‘o’ may be used uninitialized [-Werror=maybe-uninitialized]
+    834 |         memcpy(&ordered[nr_opts], o, sizeof(*o));
+        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  parse-options.c:812:30: note: ‘o’ was declared here
+    812 |         const struct option *o, *p = opts;
+        |                              ^
+  ..
+
+Fix it by initializing 'o' instead of 'p' in the above failing line 812.
+'p' is initialized afterwards in the following for-loop anyway.
+I think that was the intention of the commit ea558c86248b ("tools lib
+subcmd: Show parent options in help") in the first place.

+
+3. Auto-detected micro-architecture levels
+
+Compile by passing the '-march=native' option which, "selects the CPU
+to generate code for at compilation time by determining the processor type of
+the compiling machine. Using -march=native enables all instruction subsets
+supported by the local machine and will produce code optimized for the local
+machine under the constraints of the selected instruction set."[1]
+
+Users of Intel CPUs should select the 'Intel-Native' option and users of AMD
+CPUs should select the 'AMD-Native' option.
+
+MINOR NOTES RELATING TO INTEL ATOM PROCESSORS
+This patch also changes -march=atom to -march=bonnell in accordance with the
+gcc v4.9 changes. Upstream is using the deprecated -match=atom flags when I
+believe it should use the newer -march=bonnell flag for atom processors.[2]
+
+It is not recommended to compile on Atom-CPUs with the 'native' option.[3] The
+recommendation is to use the 'atom' option instead.
+
+BENEFITS
+Small but real speed increases are measurable using a make endpoint comparing
+a generic kernel to one built with one of the respective microarchs.
+
+See the following experimental evidence supporting this statement:
