The old code didn't work because the kernel expects a 64-bit sigset_t while the one provided by our ABI is only 32-bit. This is originally due to the fact that the kernel headers themselves define sigset_t as a 32-bit type when __KERNEL__ is not defined (apparently to cater to libc5 or some similarly old C library). We can't modify the size of sigset_t without breaking the NDK ABI, so instead perform runtime translation during the call. Change-Id: Ibfdc3cbceaff864af7a05ca193aa050047b4773f
