Author: jhibbits Date: Mon Jan 4 01:33:07 2016 New Revision: 293128 URL: https://svnweb.freebsd.org/changeset/base/293128 Log: Set the cacheline size before calling powerpc_init() powerpc_init() initializes the mmu. Since this may clear pages via pmap_zero_page(), set the cacheline size before calling into it, so pmap_zero_page() has the right cacheline size. This isn't completely necessary now, but will be when 64-bit book-e is completed.
