David S. Miller f2b6079464 sparc64: Fix cmdline_memory_size handling bugs. ... First, lmb_enforce_memory_limit() interprets it's argument (mostly, heh) as a size limit not an address limit. So pass the raw cmdline_memory_size value into it. And we don't need to check it against zero, lmb_enforce_memory_limit() does that for us. Next, free_initmem() needs special handling when the kernel command line trims the available memory. The problem case is if the trimmed out memory is where the kernel image itself resides. When that memory is trimmed out, we don't add those physical ram areas to the sparsemem active ranges, amongst other things. Which means that this free_initmem() code will free up invalid page structs, resulting in either crashes or hangs. Just quick fix this by not freeing initmem at all if "mem=" was given on the boot command line. Signed-off-by: David S. Miller <davem@davemloft.net>		17 years ago
