Maybe here are differences.
Then I suppose the RHEL kernel is a patched version from the
official Linux kernel. This is certainly not true if you look into the
official Linux kernel source (the most current 2.6.23.13). In fact, it
is not even true in the Debian GNU/Linux kernel, and the coLinux kernel.
It does not even always work on binary i386/x86_32. For Debian,
there is a "bigmem" kernel in linux that will enable the HIGHMEM support,
but that is not the default kernel. So even on a default Debian i386
you still won't see your HighTotal, HighFree, LowTotal and LowFree.
Of course you may decide to leave this issue. Maybe its the core
assumption of your algorithm, and it may be better if it only work on
RHEL kernel or i386 bigmem kernel. I only test, not use, and you are
the boss.
