[GIT PULL] Please pull powerpc/linux.git powerpc-4.12-1 tag

From: Michael Ellerman

Hi Linus,

Please pull the first set of powerpc updates for 4.12.

There's one conflict in kernel/kprobes.c, the resolution should look like:

if (symbol_name) {
addr = kprobe_lookup_name(symbol_name, offset);
if (!addr)
return ERR_PTR(-ENOENT);
}

Also due to a screw-up on my part, we need a hunk added when you merge
the powerpc tree with the KVM tree:

diff --git a/arch/powerpc/kvm/book3s_xive.c b/arch/powerpc/kvm/book3s_xive.c
index 7807ee17af4b..ffe1da95033a 100644

I haven't seen a pull request from Paolo yet, so possibly you'll need
to add that later when you merge the KVM tree.

cheers

powerpc/64s: Power9 has no LPCR[VRMASD] field so don't set it (2017-05-03 20:45:55 +1000)

----------------------------------------------------------------
powerpc updates for 4.12 part 1.

Highlights include:

- Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
virtual address space, but a process can request access to the full 512TB by
passing a hint to mmap().

- Support for the new Power9 "XIVE" interrupt controller.

- TLB flushing optimisations for the radix MMU on Power9.

- Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
Architecture 2.0".

- The ability to configure the mmap randomisation limits at build and runtime.

- Several small fixes and cleanups to the kprobes code, as well as support for
KPROBES_ON_FTRACE.

- Major improvements to handling of system reset interrupts, correctly treating
them as NMIs, giving them a dedicated stack and using a new hypervisor call
to trigger them, all of which should aid debugging and robustness.

Many fixes and other minor enhancements.
