From: Stefano Stabellini <[email protected]> There is no need to have a special case for CPU0 when converting the page-table virtual address into a physical address. The helper virt_to_maddr() is able to translate any address as long as the root page-tables is mapped in the virtual address. This is the case for all the CPUs at the moment. So use the same BUG_ON() regardless the CPU.

The example provided is wrong because to find the physical address, we need to add 'phys_offset', not substract. So I removed the comment regarding the code was buggy.

Stefano, can you confirm that you are happy with the new commit message? Cheers, -- Julien Grall
