[Qemu-ppc] [PATCH for-4.0 0/9] ppc: get rid of g_malloc(sizeof(T) * n)

[Greg Kurz]

As explained in HACKING, the g_malloc(sizeof(T) * n) construct is unsafe
because it can't detect multiplication overflowing size_t and doesn't
allow type checking.

It appears to be used in a bunch of places though:

$ git grep -E 'malloc.*sizeof' | grep ' \* '  | wc -l
101

This series fixes the ppc target and ppc machine code. The changes are
mostly trivial. Only the mac99 and e500 machines required some more work
that should be reviewed carefully, as it was only compile-tested.
