This rewrites the ppc_set_compat() function so that instead of open coding the various compatibility modes, it reads the relevant data from a table. This is a first step in consolidating the information on compatibility modes scattered across the code into a single place. It also makes one change to the logic. The old code masked the bits to be set in the PCR (Processor Compatibility Register) by which bits are valid on the host CPU. This made no sense, since it was done regardless of whether our guest CPU was the same as the host CPU or not. Furthermore, the actual PCR bits are only relevant for TCG[1] - KVM instead uses the compatibility mode we tell it in kvmppc_set_compat(). When using TCG host cpu information usually isn't even present. While we're at it, we put the new implementation in a new file to make the enormous translate_init.c a little smaller. [1] Actually it doesn't even do anything in TCG, but it will if / when we get to implementing compatibility mode logic at that level.
