scv 0 syscalls will always behave as PPC_FEATURE2_HTM_NOSC.
ptrace
------
When ptracing system calls (PTRACE_SYSCALL), the pt_regs.trap value contains
the system call type that can be used to distinguish between sc and scv 0
system calls, and the different register conventions can be accounted for.
If the value of (pt_regs.trap & 0xfff0) is 0xc00 then the system call was
performed with the sc instruction, if it is 0x3000 then the system call was
performed with the scv 0 instruction.

*
* Also, this function runs in atomic context, so __get_user() is not
* allowed to sleep. The page-fault handler detects that it is running
* in atomic context and will not try to take mmap_sem and handle the
* fault, so additional pagefault_enable()/disable() calls are not
* needed.
*
* The access can't be done via copy_from_user() here because
* vc_read_mem() must not use string instructions to access unsafe
* memory. The reason is that MOVS is emulated by the #VC handler by
* splitting the move up into a read and a write and taking a nested #VC
* exception on whatever of them is the MMIO access. Using string
