temporary pages which had some concern before, now such usage is
replaced with specific page->private.

Also switch to inplace I/O instead of allocating extra cached pages to
avoid direct reclaim under low memory scenario.

There are some bmap bugfix and minor cleanups as well"

erofs: remove a void EROFS_VERSION macro set in Makefile

Since commit 4f761fa253b4 ("erofs: rename errln/infoln/debugln to
erofs_{err, info, dbg}") the defined macro EROFS_VERSION has no affect,
therefore removing it from the Makefile is a non-functional change.

Pull staging and IIO driver updates from Greg KH:
"Here is the big staging/iio driver update for 5.4-rc1.

Lots of churn here, with a few driver/filesystems moving out of
staging finally:

- erofs moved out of staging

- greybus core code moved out of staging

Along with that, a new filesytem has been added:

- extfat

to provide support for those devices requiring that filesystem (i.e.
transfer devices to/from windows systems or printers)

Other than that, there a number of new IIO drivers, and lots and lots
and lots of staging driver cleanups and minor fixes as people continue
to dig into those for easy changes.

All of these have been in linux-next for a while with no reported
issues"

erofs: move erofs out of staging

EROFS filesystem has been merged into linux-staging for a year.

EROFS is designed to be a better solution of saving extra storage
space with guaranteed end-to-end performance for read-only files
with the help of reduced metadata, fixed-sized output compression
and decompression inplace technologies.

In the past year, EROFS was greatly improved by many people as
a staging driver, self-tested, betaed by a large number of our
internal users, successfully applied to almost all in-service
HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable
enough to be moved out of staging.

EROFS is a self-contained filesystem driver. Although there are
still some TODOs to be more generic, we have a dedicated team
actively keeping on working on EROFS in order to make it better
with the evolution of Linux kernel as the other in-kernel filesystems.

As Pavel suggested, it's better to do as one commit since git
can do moves and all histories will be saved in this way.

Let's promote it from staging and enhance it more actively as
a "real" part of kernel for more wider scenarios!
