[Linux] 2.4 Kernel and Highmem

[Nicholas Saraniti]

Actually... the application is having issues because it is running out
of memory... Poorly written app because it just segfaults/pagefaults and
dies to a prompt.

It looks like the only modification they made to the kernel was the
addition of the SCO Binaries aka

http://linux-abi.sourceforge.net/patches/linux-abi-2.4.28-1a.txt.bz2

I understand how to download a vanilla 2.4.28 kernel, and compile it, but how exactly do I compile this kernel with the patch?  I am assuming that the kernel source I will need is:
http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.28.tar.bz2

Also, they do have a vendor.config file in the kernel source directory,
I am assuming that I will need to use this somehow...

Thanks for everyones help/feedback
