    Subjectredhat 2.4.20 kernel 3.5G patch, bug report on my previous 2.4.18 kernel 3.5G patch
    Date
    Again, I've been kinda lazy about adding the configuration stuff, but, this patch applied to kernel-2.4.20-18.7.src.rpm will give
    you a kernel where PAGE_OFFSET can be set with 2 MB granularity instead of 1GB.

    BTW, there is a defect in the 2.4.18 version of this patch in the function get_pgd_slow which doesn't handle the partial PGD
    properly. In 2.4.20 the fix for this problem is in the function pgd_alloc. I will probably not have time to back port this fix to
    2.4.18.

    Anyway, for your fun and amusement, the 2.4.20 patch is working and ready for use. I haven't tried seeing just how far I can push
    PAGE_OFFSET yet, but I'd like to see how close I can get to 0xf0000000 and maybe beyond.
