Michael Ellerman 002af9391b powerpc: Split user/kernel definitions of struct pt_regs ... We use a shared definition for struct pt_regs in uapi/asm/ptrace.h. That means the layout of the structure is ABI, ie. we can't change it. That would be fine if it was only used to describe the user-visible register state of a process, but it's also the struct we use in the kernel to describe the registers saved in an interrupt frame. We'd like more flexibility in the content (and possibly layout) of the kernel version of the struct, but currently that's not possible. So split the definition into a user-visible definition which remains unchanged, and a kernel internal one. At the moment they're still identical, and we check that at build time. That's because we have code (in ptrace etc.) that assumes that they are the same. We will fix that code in future patches, and then we can break the strict symmetry between the two structs.
