powerpc/ppc64: Clean up the boot-time settings display
At boot we display a bunch of low level settings which can be useful to know, and can help to spot bugs when things are fundamentally misconfigured. At the moment they are very widely spaced, so that we can accommodate the line: ppc64_caches.dcache_line_size = 0xYY But we only print that line when the cache line size is not 128, ie. almost never, so it just makes the display look odd usually. The ppc64_caches prefix is redundant so remove it, which means we can align things a bit closer for the common case. While we're there replace the last use of camelCase (physicalMemorySize), and use phys_mem_size. Before: Starting Linux PPC64 #104 SMP Wed Aug 6 18:41:34 EST 2014 ----------------------------------------------------- ppc64_pft_size = 0x1a physicalMemorySize = 0x200000000 ppc64_caches.dcache_line_size = 0xf0 ppc64_caches.icache_line_size = 0xf0 htab_address = 0xdeadbeef htab_hash_mask = 0x7ffff physical_start = 0xf000bar ----------------------------------------------------- After: Starting Linux PPC64 #103 SMP Wed Aug 6 18:38:04 EST 2014 ----------------------------------------------------- ppc64_pft_size = 0x1a phys_mem_size = 0x200000000 dcache_line_size = 0xf0 icache_line_size = 0xf0 htab_address = 0xdeadbeef htab_hash_mask = 0x7ffff physical_start = 0xf000bar ----------------------------------------------------- This patch is final, no bike shedding ;) Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
