Hi,
I'm using RedHat Linux 7.2 with compiled kernel 2.4.25.
My serwer has one cpu "Intel(R) Pentium(R) 4 CPU 3.20GHz" with HT flag so
there are two processors in cpuinfo.
The processor has 2MB cache but `cat /proc/cpuinfo` shows only 16KB.
When I try to use 2.4.17 kernel, there is 2048KB cache but cpuinfo shows
only one cpu :)
I don't know where I should send my question, maybe You could help me.
I'll be very thankful for any answer.
Best Regards,

That's cosmetic. The CPU will still use all the cache,
since this is controlled entirely by hardware and the
OS has no influence.

If you have the time, you could try to find the changeset
that caused the problem and send Marcelo a patch ;)
