[Qemu-devel] [PATCH 02/15] target-pcc: Convert ppcemb_tlb_t to use fixed 64-bit RPN

[David Gibson <david@gibson.dropbear.id.au>]

Currently the ppcemb_tlb_t struct, used on a number of embedded ppc models
to represent a TLB entry contains a target_phys_addr_t.  That works
reasonably for now, but is troublesome for saving the state, which we'll
want to do in future.  target_phys_addr_t is a large enough type to contain
a physical address for any supported machine - and can thus, in theory at
least, vary depending on what machines are enabled other than the one
we're actually using right now.  This makes it unsuitable for describing
in vmstate.

This patch therefore changes ppcemb_tlb_t to use a fixed 64-bit integer
which we know is sufficient for all the machines which use this structure.
