[Qemu-devel] [PATCH] linux-user/mmap.c: Avoid choosing NULL as start address

mmap() is required by the linux kernel ABI and POSIX to return a non-NULL address when the implementation chooses a start address for the mapping. The current implementation of mmap_find_vma_reserved() can return NULL as start address of a mapping which leads to subsequent crashes inside the guest
