Can you describe why max_low_pfn_mapped should not be used? Is this to
allow moving the code of acpi_initrd_override() up before
init_mem_mapping() in a

Right, it'd work

Now we have pfn_mapped[] array, and max_low_pfn_mapped should not
be used anymore. Users should use pfn_mapped[] or just
1UL(32-PAGE_SHIFT) instead.

memblock deals with [@start, @end) areas, right?
that is for 32bit, when phys_addr_t is 32bit, in that case
(1ULL32) cast to 32bit would be 0.
Right, it'd

User should use arch_pfn_mapped or just 1UL<<(32-PAGE_SHIFT) instead.
Only user is ACPI_INITRD_TABLE_OVERRIDE, and it should not use that,
as later accessing is using early_ioremap(). We could change to use
