Problem syscall_mmap_impl

[R3n3r0]

*Describe the bug
I wanted to try to run an Android shellcode with Qiling, but during execution I get the following error

Sample Code

shellcode = open("./t.sc", "rb").read()
    rootfs = "examples/rootfs/arm64_android6.0"
    ostype = "android"
    archtype = "arm64"
    output = "default"

    ql = Qiling(
        code=shellcode,
        rootfs=rootfs,
        archtype=QL_ARCH.ARM64, ostype=QL_OS.LINUX, verbose=QL_VERBOSE.DEBUG
    )

Error:
