It does not contradict:
this patch: bootloader would not load initrd above 4G for 32bit kernel
max_low_pfn is below 4G.

max_low_pfn

In 32bit we will find table with phys address during 32bit flat mode
in head_32.S, because at that time we don't need set page table to
access initrd.
For copying we could use early_ioremap() with phys directly before mem mapping
is set.
To keep 32bit and 64bit consistent, use phys_addr for all.
