Currently this argument is a pointer into the stack which is used by FBT to fetch the first five probe arguments. On all non-x86 architectures it's simply the trapframe address, so this change has no functional impact. On amd64 it's a pointer into the trapframe such that stack[1 .. 5] gives the first five argument registers, which are deliberately grouped together in the amd64 trapframe definition. A trapframe argument simplifies the invop handlers on !x86 and makes the x86 FBT invop handler easier to understand. Moreover, it allows for invop handlers that may want to modify the register set of the interrupted thread. |
