I sent a patch, and a better one was done subsequently.

I should check these all, these may have been uncovered by my change to not set CONFIG_CC_OPTIMIZE_FOR_SIZE for allmodconfig, which dropped the -Wno-maybe-uninitialized.
Which compiler version are you using?

Should be easy to fix. I never saw this so far, as it's only on arm64, not arm32.

Probably a regression that shows up on all 64-bit builds, will take a look

I sent a patch
arm-multi_v5_defconfig : PASS, 0 errors, 3 warnings, 0 section mismatches
Warnings: ../kernel/cgroup.c:1634:15: warning: unused variable 'ret' [-Wunused-variable]
My patch should be merged tomorrow.

Only omapdrm remains using this. Peter Ujfalusi sent a patch for it and Tomi Valkeinen applied it and sent a pull request to dri-devel this Monday, but it has not yet shown up in linux-next, see
http://permalink.gmane.org/gmane.linux.kernel/2210499 http://lkml.iu.edu/hypermail/linux/kernel/1604.3/05431.html http://www.spinics.net/lists/dri-devel/msg106847.html
I assume it's going to be there in -rc1.
Mark, are you planning to remove the definition for 4.7 when we get there? If not, maybe do a change so we don't get a warning for the EXPORT_SYMBOL?

For v8 it's currently aarch64-linux-gnu-gcc (Linaro GCC 5.1-2015.08) 5.1.1 20150608.

Once the users are gone the function will go.
