Subject[patch-2.3.33] memory size on proliant/1600 (was Re: Ok, making , ready for pre-2.4 and code-freeze..)
Dear Linus,

As an apology for making a bit of "noise" today, here is the bugfix
for the "Memory size detected wrong on Compaq Proliant/1600" bug :)

It was to do with setup_arch() incorrectly initializing max_pfn if there
is a range with zero size.

http://www.ocston.org/~tigran/patches/proliant-2.3.33.patch

Btw, running on a machine with detected 900M (real 64M) had a side effect
of having very large page cache hashtable configured and I liked the
performance thereof - I will tune it up manually for some of my nodes.

Regards,
