Michael Ellerman 2b874a5c7b powerpc/configs: Don't enable PPC_EARLY_DEBUG in defconfigs
This reverts the remains of commit b9ef7d6b11 ("powerpc: Update
default configurations").

That commit was proceeded by a commit which added a config option to
control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and
then the update of the defconfigs was intended to not change behaviour
by then enabling the new config option.

However enabling PPC_EARLY_DEBUG had other consequences, notably
causing us to register the udbg console at the end of udbg_early_init().

This means on a system which doesn't have anything that BOOTX can
use (most systems), we register the udbg console very early but the
bootx code just throws everything away, meaning early boot messages
are never printed to the console.

What we want to happen is for the udbg console to only be registered
later (from setup_arch()) once we've setup udbg_putc, and then all
early boot messages will be replayed.

CONFIG_NR_CPUS is not set in ppc64_defconfig, So it gets default of 32

Michael Ellerman b1cfa0391a powerpc/configs: Remove unnecessary ftrace symbols
In commit 539df7fcb3 ("powerpc/configs: Enable function trace by
default") we added:

  CONFIG_FTRACE=y
  CONFIG_FUNCTION_TRACER=y
  CONFIG_FUNCTION_GRAPH_TRACER=y

To ppc64_defconfig, powernv_defconfig and pseries_defconfig.

But only CONFIG_FUNCTION_TRACER=y is required, CONFIG_FTRACE is
default y if DEBUG_KERNEL is enabled, which we have. And then
CONFIG_FUNCTION_GRAPH_TRACER is default y when CONFIG_FUNCTION_TRACER
is enabled.

The extra symbols were already removed from powernv_defconfig in
commit 9a018fb1e1 ("powerpc/config: powernv_defconfig updates").

Our defconfigs still have CONFIG_LOCKUP_DETECTOR=y, but that is no longer

none of them enabled.

Linus Torvalds 7246f60068 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.

Bartlomiej Zolnierkiewicz 7ddf3db3d7 powerpc: convert ppc64_defconfig to use libata PATA drivers
IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts ppc64_defconfig to use libata PATA
drivers.

Michael Ellerman 6b98f2bec5 powerpc/configs: Re-enable CONFIG_SCSI_DH
Commit 086b91d052 ("scsi_dh: integrate into the core SCSI code")
changed CONFIG_SCSI_DH from tristate to bool.

Our defconfigs have CONFIG_SCSI_DH=m, which the kconfig machinery warns
us is invalid, but instead of converting it to =y it leaves it unset.
This means we loose the CONFIG_SCSI_DH code and everything that depends
on it.

So convert the values in the defconfigs to =y.

Fixes: 086b91d052 ("scsi_dh: integrate into the core SCSI code")

Vasant Hegde d690740f22 powerpc/powernv: Enable LEDS support
Commit 84ad6e5c added LEDS support for PowerNV platform. Lets
update ppc64_defconfig to pick LEDS driver.

PowerNV LEDS driver looks for "/ibm,opal/leds" node in device
tree and loads if this node exists. Hence added it as 'm'.

Also note that powernv LEDS driver needs NEW_LEDS and LEDS_CLASS
as well. Hence added them to config file.

mpe: Also add them to pseries_defconfig, which is currently also used
for powernv systems.

Michael Ellerman bf4981a006 powerpc: Remove the celleb support
The celleb code has seen no actual development for ~7 years.

We (maintainers) have no access to test hardware, and it is highly
likely the code has bit-rotted.

As far as we're aware the hardware was never widely available, and is
certainly no longer available, and no one on the list has shown any
interest in it over the years.

So remove it. If anyone has one and cares please speak up.

Michael Ellerman a85cade676 powerpc: Update all configs using savedefconfig
It looks like it's ~4 years since we updated some of these, so do a bulk
update.

Verified that the before and after generated configs are exactly the
same.

Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

Linus Torvalds fd9879b9bb Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux
Pull powerpc updates from Michael Ellerman:
 "Here's a first pull request for powerpc updates for 3.18.

  The bulk of the additions are for the "cxl" driver, for IBM's Coherent
  Accelerator Processor Interface (CAPI).  Most of it's in drivers/misc,
  which Greg & Arnd maintain, Greg said he was happy for us to take it
  through our tree.

  There's the usual minor cleanups and fixes, including a bit of noise
  in drivers from some of those.  A bunch of updates to our EEH code,
  which has been getting more testing.  Several nice speedups from
  Anton, including 20% in clear_page().

  And a bunch of updates for freescale from Scott"
