hibernation image size

[arden jay <arden.jay@xxxxxxxxx>]

Hi,

I'm trying to decrease hibernation image size.

It's now, normal:21762, high: 8883 pages.

Dump /proc/vmalloc, I can see those occupied high memory region.

For example:
0xd99f8000-0xd99fd000   20480 init_mmdc_settings+0x3c/0x410 ioremap
...
0xd9a1e000-0xd9a3b000  118784 gckOS_AllocateMemory+0x44/0x60 pages=28 vmalloc

For those ioremap region, pfn_valid check won't pass, so they shouldn't save in hibernation image, right?

And I can see some vmalloc, I think those will be saved in hibernation image.

To sum those vmalloc regions, I can't get the number calculated in count_highmem_pages.

Can anyone show me how to dig out further?

jay
