Not sure what you are talking about, it’s definitely endian neutral. You can’t take different page sized fs and put it on another page size arch, but that’s a separate issue.
2013 MIPS on Cavium as big endian -vs- Intel x86-64; appeared to work, did not. Page size not an issue, appeared to work, occasionally crazy with dumps containing values that are recognizably scrambled.
It's been awhile since then, but that was our experience. I don't have access to the records or email from the time. Maybe it's been fixed.
