Could be worse. Essentially every allmodconfig/allyesconfig which doesn't configure pm
is affected.

With my tests (v4.4-10282-geae2177):

Build results:
	total: 146 pass: 142 fail: 4
Failed builds:
	alpha:allmodconfig
	m68k:allmodconfig
	parisc:allmodconfig
	xtensa:allmodconfig

Qemu test results:
	total: 96 pass: 94 fail: 2
Failed tests:
	arm64:smp:defconfig
	arm64:nosmp:defconfig

arm64 qemu tests are broken for a different reason. There is a patch to fix it,
but for some reason it didn't make it into mainline (yet). It is in -next, though.
