Why are there so many more patches for v4.9 than for more recent kernels?

The v4.11..v4.14 range got processed, and all those commits are now being pushed into 4.9 and older.

The bcm63xx SPI controller does not allow manual control of the CS lines and will toggle it automatically before and after sending data, so we are limited to messages that fit in the FIFO buffer. Since the CS lines aren't available as GPIOs either, we will need to make slave drivers aware of this limitation so they can handle them accordingly.

This seems really aggressive for stable...

Why so?
