Hi all,

CONFIG_PHYS_64BIT enables kernel support for larger than 32-bit physical
addresses. Is it this configuration option we have to enable for the
support of 36-bit real memory (as are capable the Freescale e500v2 or
e500mc cores family) ?

The Hugetlb patch for BookE (
seems to be surbordinated to CONFIG_PHYS_64BIT. Is there any good reason
why it is not supported when CONFIG_PHYS_64BIT is disabled ?
