This patchset include patches for supporting 64TB with ppc64. I haven't booted

less memory. Changes extend VSID bits to 38 bits for a 256MB segment

Is this a real problem that can occur? The DMA driver used to have a

Commit b38c77d82e4 moved the MTMSR_EERI macro from the KVM code to generic
ppc_asm.h code. However, while adding it in the headers for the ppc32 case,
it missed out to remove the former definition in the KVM code.
This patch fixes compilation on server type PPC32 targets with CONFIG_KVM
enabled.
