Why can't Jisheng Zhang base his patches on top of Mark's changes and
place the new file directly under drivers/ ?

Why do it as a two-step process with it first appearing in arch/arm,
and then having to generate another patch at a later date to move it
elsewhere. That just creates more noise, and we should be avoiding
generating noise in arch/arm.

This is what Linus has said in his -rc4 release notes yesterday:

Other than that issue, it's mostly drivers and networking. USB, gpu,
mmc, network drivers, sound. With some ARM noise (but even that is
mostly driver-related: dts updates due to MMC fixes). And a few small
filesystem fixes.

and we can infer from the phrase "ARM noise" that Linus' opinion of
arch/arm is still fairly low, and still doesn't regard the "churn" in
arch/arm as being useful.
