Enable MTE on Pixel 8

The Pixel 8 hardware (Tensor G3) supports the ARM Memory Tagging Extension (MTE), and software support is available both in Android userspace and the Linux kernel. This feature is a powerful defense against linear buffer overflows and many types of use-after-free flaws. I'm extremely happy to see this hardware finally available in the real world.

You can enable this feature in both Android and the kernel, as the post explains. Sadly, the post does not explain if there's any downsides to enabling this extension, and I'm certainly not the right person to investigate that. Does anyone in our audience know?
