Add a new setup_data type SETUP_EFI for kexec use.  Passing the saved
fw_vendor, runtime, config tables and EFI runtime mappings.

When entering virtual mode, directly mapping the EFI runtime regions
which we passed in previously. And skip the step to call
SetVirtualAddressMap().

Specially for HP z420 workstation we need save the smbios physical
address.  The kernel boot sequence proceeds in the following order.
Step 2 requires efi.smbios to be the physical address.  However, I found
that on HP z420 EFI system table has a virtual address of SMBIOS in step
1.  Hence, we need set it back to the physical address with the smbios
in efi_setup_data.  (When it is still the physical address, it simply
sets the same value.)

1. efi_init() - Set efi.smbios from EFI system table
2. dmi_scan_machine() - Temporary map efi.smbios to access SMBIOS table
3. efi_enter_virtual_mode() - Map EFI ranges

Tested on ovmf+qemu, lenovo thinkpad, a dell laptop and an
HP z420 workstation.

kexec kernel will need exactly same mapping for EFI runtime memory
ranges. Thus here export the runtime ranges mapping to sysfs,
kexec-tools will assemble them and pass to 2nd kernel via setup_data.

Introducing a new directory /sys/firmware/efi/runtime-map just like
/sys/firmware/memmap. Containing below attribute in each file of that
directory:

attribute  num_pages  phys_addr  type  virt_addr

Export fw_vendor, runtime and config table physical addresses to
/sys/firmware/efi/{fw_vendor,runtime,config_table} because kexec kernels
need them.

From EFI spec these 3 variables will be updated to virtual address after
entering virtual mode. But kernel startup code will need the physical
address.

Pull third set of powerpc updates from Benjamin Herrenschmidt:
 "This is a small collection of random bug fixes and a few improvements
  of Oops output which I deemed valuable enough to include as well.

  The fixes are essentially recent build breakage and regressions, and a
  couple of older bugs such as the DTL log duplication, the EEH issue
  with PCI_COMMAND_MASTER and the problem with small contexts passed to
  get/set_context with VSX enabled"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/signals: Mark VSX not saved with small contexts
  powerpc/pseries: Fix SMP=n build of rng.c
  powerpc: Make cpu_to_chip_id() available when SMP=n
  powerpc/vio: Fix a dma_mask issue of vio
  powerpc: booke: Fix build failures
  powerpc: ppc64 address space capped at 32TB, mmap randomisation disabled
  powerpc: Only print PACATMSCRATCH in oops when TM is active
  powerpc/pseries: Duplicate dtl entries sometimes sent to userspace
  powerpc: Remove a few lines of oops output
  powerpc: Print DAR and DSISR on machine check oopses
  powerpc: Fix __get_user_pages_fast() irq handling
  powerpc/eeh: More accurate log
  powerpc/eeh: Enable PCI_COMMAND_MASTER for PCI bridges

current_headset_type should be of the HEADSET_TYPE enum, not the
HEADSET_MODE enum. Since ALC_HEADSET_TYPE_UNKNOWN and ALC_HEADSET_MODE_UNKNOWN
are both 0, this patch is just janitorial.

Some models (or maybe depending on BIOS version) of Sony VAIO with
ALC260 give no proper pin configurations as default, resulting in the
non-working speaker, etc.  Just provide the whole pin configurations
via a fixup.
