I've noticed a small typo in the changelog.
As reported by https://bugzilla.kernel.org/show_bug.cgi?id=53501,
"MemTotal" from /proc/meminfo means memory pages managed by the buddy
system (managed_pages), but "MemTotal" from /sys/.../node/nodex/meminfo
means phsical pages present (present_pages) within the NUMA node.
s/phsical/physical/
There's a difference between managed_pages and present_pages due to
bootmem allocator and reserved pages.
And Documentation/filesystems/proc.txt says
MemTotal: Total usable ram (i.e. physical ram minus a few reserved
bits and the kernel binary code)
So change /sys/.../node/nodex/meminfo to report available pages within
the node as "MemTotal".
