Unit test results:
	pass: 594143 fail: 0

There is a new build failure, affecting openrisc, parisc, and xtensa.
Example from parisc:

Building parisc:allmodconfig ... failed
--------------
Error log:
ERROR: modpost: "__divdi3" [fs/xfs/xfs.ko] undefined!
ERROR: modpost: "__umoddi3" [fs/xfs/xfs.ko] undefined!
ERROR: modpost: "__moddi3" [fs/xfs/xfs.ko] undefined!
ERROR: modpost: "__udivdi3" [fs/xfs/xfs.ko] undefined!

Commit 845abeb1f06a ("xfs: add tunable threshold parameter for triggering
zone GC") introduced a 64-bit divide operation. I reported this to the
author, and a fix is in discussion.

Other than that, there is the known allyesconfig build failure for
x86_64:allyesconfig. I submitted a number of different proposals for
fixing it. We'll see if one of them makes it.

The fix for the mipsel64 test failure is known and will hopefully be pushed
soon.
