Hi all, This patch teaches the user space emulator about host pages. It marks present host page mappings with PAGE_RESERVED so mmap_find_vma() properly can detect that pages at mmap_next_start should be skipped over instead of being overwritten using mmap(). Without this patch I experience crashes with the arm or sh4 user space emulator together with sbox2. This combination sometimes result in that host libraries are mapped into the qemu process space starting from 0x4xxxxxxx instead of 0xb7xxxxxx. This together with the initial value of mmap_next_start results in a segfault when the elf loader overwrites the mapped host libraries with the target binary.
Comments anyone? / magnus
