    powerpc/ppc64: Clean up the boot-time settings display · bdce97e9
    Michael Ellerman authored
    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 ;)
