4.13-rc0: stopped booting on Nokia N900

Hi!

First, I got segfault from make:

: 0: Can't open
scripts/Makefile.build:561: recipe for target
'drivers/iio/imu/st_lsm6dsx' failed
make[3]: *** [drivers/iio/imu/st_lsm6dsx] Segmentation fault (core
dumped)
scripts/Makefile.build:561: recipe for target 'drivers/iio/imu' failed
make[2]: *** [drivers/iio/imu] Error 2
scripts/Makefile.build:561: recipe for target 'drivers/iio' failed
make[1]: *** [drivers/iio] Error 2
make[1]: *** Waiting for unfinished jobs....
Makefile:1008: recipe for target 'drivers' failed
make: *** [drivers] Error 2
make: *** Waiting for unfinished jobs....
pavel@duo:/data/l/linux-n900$ ./mkit

Then compile worked, but it failed to boot. I've now cleaned caches
and am rebuilding to make sure it is not build machine that has
glitches.

No such luck :-(.

I tested linux-next relatively recently, and it worked ok.

af3c8d98508d37541d4bf57f13a984a7f73a328c is broken.
650fc87 worked ok.

Best regards,

								Pavel

2b97620 is broken.

commit a51166ce71844ffbb8f78d63647b44dd69e46cf1
    Add linux-next specific files for 20170628

was ok.

Not sure if it's the same issue, but I bisected down an issue with commit
46e48e257360 ("genirq: Move irq resource handling out of spinlocked region"),
so adding Thomas.

I saw your message too late and also bisected the issue I saw to this:

46e48e257360f0845fe17089713cbad4db611e70 is the first bad commit
