    powerpc/mm: Fix virt_addr_valid() etc. on 64-bit hash
    
    virt_addr_valid() is supposed to tell you if it's OK to call virt_to_page() on
    an address. What this means in practice is that it should only return true for
    addresses in the linear mapping which are backed by a valid PFN.
    
    We are failing to properly check that the address is in the linear mapping,
    because virt_to_pfn() will return a valid looking PFN for more or less any
    address. That bug is actually caused by __pa(), used in virt_to_pfn().
    
    eg: __pa(0xc000000000010000) = 0x10000  # Good
        __pa(0xd000000000010000) = 0x10000  # Bad!
        __pa(0x0000000000010000) = 0x10000  # Bad!
    
    This started happening after commit bdbc29c19b26 ("powerpc: Work around gcc
    miscompilation of __pa() on 64-bit") (Aug 2013), where we changed the definition
    of __pa() to work around a GCC bug. Prior to that we subtracted PAGE_OFFSET from
    the value passed to __pa(), meaning __pa() of a 0xd or 0x0 address would give
    you something bogus back.
    
    Until we can verify if that GCC bug is no longer an issue, or come up with
    another solution, this commit does the minimal fix to make virt_addr_valid()
    work, by explicitly checking that the address is in the linear mapping region.
