-Subject: devtmpfs: mount with noexec and nosuid
-
-devtmpfs is writable. Add the noexec and nosuid as default mount flags
-to prevent code execution from /dev. The systems who don't use systemd
-and who rely on CONFIG_DEVTMPFS_MOUNT=y are the ones to be protected by
-this patch. Other systems are fine with the udev solution.
-
-No sane program should be relying on executing from /dev. So this patch
-reduces the attack surface. It doesn't prevent any specific attack, but
-it reduces the possibility that someone can use /dev as a place to put
-executable code. Chrome OS has been carrying this patch for several
-years. It seems trivial and simple solution to improve the protection of
-/dev when CONFIG_DEVTMPFS_MOUNT=y.

-Subject: [PATCH 2/4] net: dpaa2-mac: add support for more 10G modes
-
-Phylink documentation says:
- * Note that the PHY may be able to transform from one connection
- * technology to another, so, eg, don't clear 1000BaseX just
- * because the MAC is unable to BaseX mode. This is more about
- * clearing unsupported speeds and duplex settings. The port modes
- * should not be cleared; phylink_set_port_modes() will help with this.
-
-So add the missing 10G modes.

-Subject: [PATCH 1/4] dpaa2-eth: do not hold rtnl_lock on phylink_create() or
- _destroy()
-
-The rtnl_lock should not be held when calling phylink_create() or
-phylink_destroy() since it leads to the deadlock listed below:
-
-[ 18.656576] rtnl_lock+0x18/0x20
-[ 18.659798] sfp_bus_add_upstream+0x28/0x90
-[ 18.663974] phylink_create+0x2cc/0x828
-[ 18.667803] dpaa2_mac_connect+0x14c/0x2a8
-[ 18.671890] dpaa2_eth_connect_mac+0x94/0xd8
-
-Fix this by moving the _lock() and _unlock() calls just outside of
-phylink_of_phy_connect() and phylink_disconnect_phy().
