Hi All, Sebastian,

Hi Grygorii,

3) Seems there are some problem with HIGHMEM :(. System crashes if I'm trying
   to run hackbench (see log 1). I can run hackbench only if HIGHMEM is disabled.
   I've also tried to disable CONFIG_CPU_SW_DOMAIN_PAN, CONFIG_ARM_PATCH_PHYS_VIRT,
   and CONFIG_CPUSETS, before disabling HIGHMEM.
   Sorry, I'll not able to investigate it further because of Christmas holidays here.

I see. It seems not to trigger anything on x86.

Yah. I saw other reports - it seems this issue is not triggered on ARM SMP also
(as per report from Tim Sander). Will try to dig deeper.

4) Could we revert commit 4fa5422 'ARM: OMAP2: Drop the concept of certain power
   domains not being able to lose context.'? It's not required for 4.4-rt wakeup
   and introduces build warnings.

done.

Thanks.
