This does not go without saying that the patchset is not 100% complete.
It is missing:
- a way to disable memmap_on_memory (either sysfs or boot_time cmd)
- atm, arch_add_memory for s390 screams if an altmap is passed.
I am still thinking of a way to nicely drop handle that.
Maybe a function in s390 that sets memmap_on_memory false and
stuff that check in support_memmap_on_memory function.
Or simply implement altmap support ... shouldn't be too hard :)
Yeah, I guess so, but first I would like to have everything else settled.
So, gentle ping :-)
I'm planning on looking into patch #2/3 later this or next week (this
week is open source summit / KVM Forum).
One thing to look into right now is how to make this fly this with
vmemmap optimizations for hugetlb pages.
