[External] : Re: [PATCH] Documentation/arm64: update memory layout table.

[André Müller]

Sorry about using the incorrect email address, Russell, I just took the one from
the b89ddf4cca43 commit.

I agree. We also found the table useful for getting a quick overview. Even
though it is now obvious, that the information in the table needs to be double
checked, if you want to rely on it.

Best regards,
André
