Subject: [RFC PATCH v1 00/33] accurately calculate pages managed by buddy system

The original goal of this patchset is to fix the bug reported by
https://bugzilla.kernel.org/show_bug.cgi?id=53501
Now it has also been expanded to reduce common code used by memory
initializion. In total it has reduced about 550 lines of code.
Patch 1:
Extract common help functions from free_init_mem() and
free_initrd_mem() on different architectures.
Patch 2-27:
Use help functions to simplify free_init_mem() and
free_initrd_mem() on different architectures. This has reduced
about 500 lines of code.
Patch 28:
Introduce common help function to free highmem pages when
initializing memory subsystem.
Patch 29-32:
Adjust totalhigh_pages, totalram_pages and zone->managed_pages
altogether when reserving/unreserving pages.
Patch 33:
Change /sys/.../node/nodex/meminfo to report available pages
within the node as "MemTotal".
We have only tested these patchset on x86 platforms, and have done basic
compliation tests using cross-compilers from ftp.kernel.org. That means
some code may not pass compilation on some architectures. So any help
to test this patchset are welcomed!
