Turns out that there are a few invalid uses of pfn_to_page() in the
normal code. If you hand-apply the following chunks, it gets a bit
farther into boot. These aren't permanent fixes. We really need a
last_lowmem_pfn instead of highstart_pfn.
static void __init set_max_mapnr_init(void)
{
#ifdef CONFIG_HIGHMEM
- highmem_start_page = pfn_to_page(highstart_pfn);
+ highmem_start_page = pfn_to_page(highstart_pfn-1);
max_mapnr = num_physpages = highend_pfn;
#else
