start_mem is treated differently in mem_init. This change appears to have occurred when e820 support was added to 2.3.x, although it could (possibly) be BIGMEM-related.
From 2.2.13: ... mem_init(unsigned long start_mem, unsigned long end_mem )
...
start_mem = PAGE_ALIGN(start_mem);
...
while (start_mem < end_mem) { ... start_mem += PAGE_SIZE; }
...
else if (tmp >= (unsigned long) &__bss_start && tmp < (unsigned long start_mem) datapages++; else reservedpages++; continue;
From 2.3.22: ... mem_init(unsigned long start_mem, unsigned long end_mem )
...
start_mem = PAGE_ALIGN(start_mem);
...
else if (tmp >= (unsigned long) &__bss_start && tmp < (unsigned long start_mem) datapages++; else reservedpages++; continue;
Now datapages and reservedpages are local to mem_init, and used only for a printk which reports memory to dmesg. I shall assume that 2.2.13 is correct, and my patch will include a fix for 2.3.22.
