[PATCH 0/5] Rate limited printing for Rust

[Alice Ryhl]

To avoid DoS on the kernel log, the Rust Binder driver is being switched
to rate limited printing. But before we can do that, we must first
implement rate limited printing for Rust. Thus, do that.

However, it turns out that before we can implement rate limited
printing, we must first implement the ability declare a raw_spinlock_t
in a global variable. Thus, do that too.

The core Rust part of the series applies on top of 7.1-rc6, but the
Binder patches require some other Binder changes. I'll be resending a
more useful and easier to apply series after the merge window.
