Hi,
when using mmap with qemu-i386 on x86_64 it's quite simple to get 32-bit
pointers back (using the MAP_32BIT flag, thanks to Kirill for the patch).
I'm currently in the need for shared memory though, so I need shmat() to
return something within the lower 31 Bits as well.
shmget(0x56a4d5, 488, IPC_CREAT|0660) = 11075627
shmat(11075627, 0, 0) = 0x2b4ceb29e000
Does anyone have an idea how to get around this and force shmat to
return something a 32-bit target can handle? In the end it only calls
mmap too...
Thanks,
Alex
