+qemu-i386 mmap but offset greater than 32 bits
+
+I don't know if it's a problem, but I did, and it bothered me for a long time.
+When I use qemu-i386 and interact with the video card device,an error has occurred:
+
+18534 ioctl(4,DRM_IOCTL_MODE_GETENCODER,{39,0,0,0,0}) = 0 ({39,4,34,3,0})
+18534 ioctl(4,DRM_IOCTL_MODE_CREATE_DUMB,{1080,1920,32,0,0,0,0}) = 0 ({1080,1920,32,0,1,7680,8294400})
+18534 ioctl(4,DRM_IOCTL_MODE_ADDFB,{0,1920,1080,7680,32,24,1}) = 0 ({66,1920,1080,7680,32,24,1})
+18534 ioctl(4,DRM_IOCTL_MODE_MAP_DUMB,{1,0,0}) = 0 ({1,0,5543018496})
+18534 mmap2(NULL,8294400,PROT_READ|PROT_WRITE,MAP_SHARED,4,0x14a63c) = -1 errno=22 (Invalid argument)
+
+"5543018496" is the offset through ioctl() and it is "0x14a63c000".
+In qemu：
+ret = target_mmap(arg1, arg2, arg3,
+      target_to_host_bitmask(arg4, mmap_flags_tbl),
+      arg5, arg6 << MMAP_SHIFT);
+
+The type of "arg6" is ulong.When use qemu-i386, arg6 can't be set to "0x14a63c000".So it's wrong for my program.
+
+I want to find a good way to deal with this kind of problem, but I'm not very familiar with QEMU，
+so I came to ask how to deal with this problem.
+
+Thank you！
