Hello,
While booting the v4.11 kernel I found the below issue.
The summary of the issue mentions
Commit 4a9d4b024a31 ("switch fput to task_work_add") implements a
schedule_work() for completing fput(), but did not guarantee calling
__fput() after unpacking initramfs. Because of this

This was simply a missing break statement, causing an unwanted fall

Hello,
These are a few compile error and warning fixes which were pointed out
after the 4.11 code was merged.
Most of these could be found at this kbuild failure here:
https://lkml.org/lkml/2017/3/9/976
The rest I found with some local testing.

Cleanups to whitespace and add some comments. Reading through the delay
slot logic I noticed some things:
- Delay slot instructions were not indented
- Some comments are not lined up
- Use tabs and spaces consistent with other code
No functional change

In the end I ended up going with Word Copies + Loop Unrolls as it

Noticed this when building with allyesconfig. Got build failures due
to iounmap and __ioremap symbols missing. This patch exports them so
modules can use them. This is inline with other architectures.

The latest openrisc kernel patchs in linux-next are failing to build due
to old toolchains at the crosstool website.
Update to point the the toolchain binaries released the OpenRISC team.

This was causing a build failure for openrisc when using musl and
gcc 5.4.0 since the file is not available in the toolchain.
It doesnt seem this is needed and removing it does not cause any build
warnings for me.
