Oh. It's an
x86_64? You didn't say originally, so I assumed an ia32. OK, I believe my modified math above is correct.If the your kernel was compiled using the default larger page size (isn't that 16K?), then the explanation is simple: Linux generates
x86-64 uses 4K pages, just like i386. It doesn't support bigger pages.
