From: Yang Yingliang <yangyingli...@huawei.com>
In ILP32, the sigaction struct is the same as AARCH64.
To allow for this to work, we use a long long fields and
then add extra casts when converting between the user
exposed struct and the kernel exposed struct.
The modify is came from a patch of glibc,
the commit is 9266f4b060f6("Add kernel_sigaction.h for AARCH64 ILP32").
