Tried out the above patch.
It seems to be working; no panic, total memory has increased and
the hot-added memory is added as HIGHMEM.
I had to backout Oscar's first section of patch
https://bugzilla.kernel.org/show_bug.cgi?id=206401#c28
since it spams console too much and bogs down systemd.
Minimal install of 168MB memory worked, so this time the sample is
running anaconda installer starting at 512MB.
Eventually memory was hot-added to around 1.2GB.
The weird pr_info() from populate_section_memmap() is still remaining though...
2nd parameter of add_memory() (phys_addr_t, 32bit on non-PAE) is
going up to 0x60000000, so drivers/hv/hv_balloon.c:hv_mem_hot_add() may need
limit check to not overflow 4GB for heavier usage.
(Yes you should limit it in hypervisor dialog, but default is 1TB)
Do we need modifications for arch/x86/mm/init_32.c:arch_add_memory()
so that the hot-added memory is always in highmem area?
Currently it just >>PAGE_SHIFT given parameters and call generic __add_pages().
