How are people to test this?  "does it boot"?

I've been running kernels with Gerry's 5 patches applied for 11 days
now. This is on a 64bit laptop but with a 32bit kernel + HIGHMEM. I
joined the conversation because my laptop would not resume from suspend
to disk - it either froze or rebooted. With the patches applied the
laptop does successfully resume and has been stable.

Since Monday, I have have been running a kernel with the patches (plus,
from today, the patch you mailed yesterday) applied to 3.7rc7, without
problems.

I've been running 3.7-rc7 with the patches listed below for a week now
and it has been perfectly stable. In particular, my laptop will now
successfully resume from suspend to disk, which always failed without
the patches.

I should have said, of course, that it was -rc6 and earlier that would 
not boot without Jiang Liu's patches. I applied those patches to rc-6 
and my resume after suspend to disk problem was fixed. For a subsequent 
week I have been running with the patches applied to -rc7, with Andrew's 
patch also applied for the last 3 days. -rc7 was not subject to the 
resume problem because the patch which broke it had been reverted.
All this has been on a 64bit laptop, but running a 32bit kernel with 
HIGHMEM.

Apologies for yesterday's inaccuracy. I shouldn't send testing reports 
when I'm in a hurry.

 From Jiang Liu:
1. [RFT PATCH v2 1/5] mm: introduce new field "managed_pages" to struct
zone
2. [RFT PATCH v1 2/5] mm: replace zone->present_pages with
zone->managed_pages if appreciated
3. [RFT PATCH v1 3/5] mm: set zone->present_pages to number of existing
pages in the zone
4. [RFT PATCH v2 4/5] mm: provide more accurate estimation of pages
occupied by memmap
5. [RFT PATCH v1 5/5] mm: increase totalram_pages when free pages
allocated by bootmem allocator
