It would be nice if prelink default policy avoided 0 .. 0x111000 (1MB + 64KB + 4KB) so that vm86 could run various programs that use "himem" where the segment base is 0xffff0 (1MB - 16) and inclusive limit is 0xffff, which gives a highest address of 0x10ffef. [It would have been nice if the default linux kernel loaded at 0x110000 instead of 0x100000. Then Win3.1 and linux could have co-existed in memory.] -- -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
