powerpc/64: Fix L1D cache shape vector reporting L1I values
It seems we didn't pay quite enough attention when testing the new cache shape vectors, which means we didn't notice the bug where the vector for the L1D was using the L1I values. Fix it, resulting in eg: L1I cache size: 0x8000 32768B 32K L1I line size: 0x80 8-way associative L1D cache size: 0x10000 65536B 64K L1D line size: 0x80 8-way associative Fixes: 98a5f361b862 ("powerpc: Add new cache geometry aux vectors") Cut-and-paste-bug-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Badly-reviewed-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
