This issue still exists in latest -git.  It goes away when
CONFIG_PHYS_ADDR_T_64BIT
is disabled, but then we lose PCI and PCMCIA (and other chipselect signals which
are mapped beyond 4G).

I'm going to look into this today if nobody beats me to it.

Hey Manuel.

I'm sorry that I did not pay attention and see this on the mailing list. I
will get a fix out today (tomorrow your time).

Hi Steve,

Did you ever fix this? I don't see anything in patchwork from you since
a long time before this email.

I believe the same issue occurs if you take any system with a 32 bit
kernel (eg. malta or boston) & select ARCH_PHYS_ADDR_T_64BIT.

One issue is that iPTE_SW tries to ori a mode with bits beyond bit 15
set if you are running that 32 bit kernel on a 64 bit CPU, leading to
uasm overflow errors & garbage TLB handlers. Just having it or in all of
mode isn't sufficient to get things working though.

Thanks,
    Paul
