Various mips64 and ppc64 qemu tests crash as follows
in v4.14.y and v4.17.y (the log is from ppc64).

I started to bisect, but abandoned it after finding commit 62d7ce7f40a9
("posix-timers: Fix nanosleep_copyout() for CONFIG_COMPAT_32BIT_TIME")
in both branches. Since there is no "config COMPAT_32BIT_TIME" in v4.14.y
or v4.17.y, some relevant code is commented out by the commit, which in
turn results in the crash.

That patch is already gone from my patch queue, let me push out new -rc
git trees to help make it easier for you.

No worries.
Here is another build failure, affecting v4.9.y and v4.14.y.
Building arm:versatilepb-scsi:versatile_defconfig:versatile-pb ... failed
------------
Error log:
drivers/pci/host/pci-versatile.c: In function 'versatile_pci_parse_request_of_pci_ranges':
drivers/pci/host/pci-versatile.c:92:10: error:
implicit declaration of function 'devm_pci_remap_iospace'
This is due to 506b73aa8f6f ("PCI: versatile: Fix I/O space page leak").
SHA is from v4.14.y. There is no devm_pci_remap_iospace() in those releases.

The author of that said he would be providing a fix for this soon. If
it doesn't show up by tomorrow, I'll just drop it.
