16 a 64-byte boundary by 0, 4 or 5 instructions. Since the vdso trampoline
17 is not on the stack, we need a new variant with different offsets and
18 data to tell gdb where to find the signal context on the stack.

20 Here we put the offset to the context data at the start of the trampoline
21 region and offset the first trampoline by 2 instructions. Please do
