2907f851f6 xsysace: Remove SYSACE driver
Sysace IP is no longer used on Xilinx PowerPC 405/440 and Microblaze
systems. The driver is not regularly tested and very likely not working for
quite a long time that's why remove it.

b12b472496 powerpc updates for 5.12
A large series adding wrappers for our interrupt handlers, so that irq/nmi/user
 tracking can be isolated in the wrappers rather than spread in each handler.
 
 Conversion of the 32-bit syscall handling into C.
 
 A series from Nick to streamline our TLB flushing when using the Radix MMU.
 
 Switch to using queued spinlocks by default for 64-bit server CPUs.
 
 A rework of our PCI probing so that it happens later in boot, when more generic
 infrastructure is available.
 
 Two small fixes to allow 32-bit little-endian processes to run on 64-bit
 kernels.
 
 Other smaller features, fixes & cleanups.

665d8d5876 powerpc/akebono: Fix unmet dependency errors
The AKEBONO config has various selects under it, including some with
user-selectable dependencies, which means those dependencies can be
disabled. This leads to warnings from Kconfig.

This can be seen with eg:

  $ make allnoconfig
  $ ./scripts/config --file build~/.config -k -e CONFIG_44x -k -e CONFIG_PPC_47x -e CONFIG_AKEBONO
  $ make olddefconfig

  WARNING: unmet direct dependencies detected for ATA
    Depends on [n]: HAS_IOMEM [=y] && BLOCK [=n]
    Selected by [y]:
    - AKEBONO [=y] && PPC_47x [=y]

  WARNING: unmet direct dependencies detected for NETDEVICES
    Depends on [n]: NET [=n]
    Selected by [y]:
    - AKEBONO [=y] && PPC_47x [=y]

  WARNING: unmet direct dependencies detected for ETHERNET
    Depends on [n]: NETDEVICES [=y] && NET [=n]
    Selected by [y]:
    - AKEBONO [=y] && PPC_47x [=y]

  WARNING: unmet direct dependencies detected for MMC_SDHCI
    Depends on [n]: MMC [=n] && HAS_DMA [=y]
    Selected by [y]:
    - AKEBONO [=y] && PPC_47x [=y]

  WARNING: unmet direct dependencies detected for MMC_SDHCI_PLTFM
    Depends on [n]: MMC [=n] && MMC_SDHCI [=y]
    Selected by [y]:
    - AKEBONO [=y] && PPC_47x [=y]

The problem is that AKEBONO is using select to enable things that are
not true dependencies, but rather things you probably want enabled in
an AKEBONO kernel. That is what a defconfig is for.

So drop those selects and instead move those symbols into the
defconfig. This fixes all the kconfig warnings, and the result of make
44x/akebono_defconfig is the same before and after the patch.

7a3c90df20 arch: powerpc: Stop building and using oprofile
The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.

This commits stops building oprofile for powerpc and removes any
reference to it from directories in arch/powerpc/ apart from
arch/powerpc/oprofile, which will be removed in the next commit (this is
broken into two commits as the size of the commit became very big, ~5k
lines).

Note that the member "oprofile_cpu_type" in "struct cpu_spec" isn't
removed as it was also used by other parts of the code.

In commit 961518259b ("rcu: Enable RCU tracepoints by default to aid

which it is for some of our configs).

That in turn causes CONFIG_TREE_RCU_TRACE to be enabled, which selects
CONFIG_DEBUG_FS. The end result is that CONFIG_DEBUG_FS is forced on,
meaning we don't have to enable it in some of our configs.

c5aec4c76a Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Ben Herrenschmidt:
 "Here is the bulk of the powerpc changes for this merge window.  It got
  a bit delayed in part because I wasn't paying attention, and in part
  because I discovered I had a core PCI change without a PCI maintainer
  ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
  probably improve it later and I didn't want to rebase to add his ack.

  There is going to be a bit more next week, essentially fixes that I
  still want to sort through and test.

  The biggest item this time is the support to build the ppc64 LE kernel
  with our new v2 ABI.  We previously supported v2 userspace but the
  kernel itself was a tougher nut to crack.  This is now sorted mostly
  thanks to Anton and Rusty.

  We also have a fairly big series from Cedric that add support for
  64-bit LE zImage boot wrapper.  This was made harder by the fact that
  traditionally our zImage wrapper was always 32-bit, but our new LE
  toolchains don't really support 32-bit anymore (it's somewhat there
  but not really "supported") so we didn't want to rely on it.  This
  meant more churn that just endian fixes.

  This brings some more LE bits as well, such as the ability to run in
  LE mode without a hypervisor (ie. under OPAL firmware) by doing the
  right OPAL call to reinitialize the CPU to take HV interrupts in the
  right mode and the usual pile of endian fixes.

  There's another series from Gavin adding EEH improvements (one day we
  *will* have a release with less than 20 EEH patches, I promise!).

  Another highlight is the support for the "Split core" functionality on
  P8 by Michael.  This allows a P8 core to be split into "sub cores" of
  4 threads which allows the subcores to run different guests under KVM
  (the HW still doesn't support a partition per thread).

  And then the usual misc bits and fixes ..."

0f890c8d20 powerpc: Rename mapping based RELOCATABLE to DYNAMIC_MEMSTART for BookE
The current implementation of CONFIG_RELOCATABLE in BookE is based
on mapping the page aligned kernel load address to KERNELBASE. This
approach however is not enough for platforms, where the TLB page size
is large (e.g, 256M on 44x). So we are renaming the RELOCATABLE used
currently in BookE to DYNAMIC_MEMSTART to reflect the actual method.

The CONFIG_RELOCATABLE for PPC32(BookE) based on processing of the
dynamic relocations will be introduced in the later in the patch series.

This change would allow the use of the old method of RELOCATABLE for
platforms which can afford to enforce the page alignment (platforms with
smaller TLB size).

Changes since v3:

* Introduced a new config, NONSTATIC_KERNEL, to denote a kernel which is
  either a RELOCATABLE or DYNAMIC_MEMSTART(Suggested by: Josh Boyer)

3b3bceef26 net: fix IBM EMAC driver after rename.
In commit 9aa3283595 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*

The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors).  In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.

We do not explicitly select the Kconfig dependencies, as this would force
EMAC on.  Doing it in the defconfig allows more flexibility.

Tested on a canyondlands board.

9661534d6a powerpc/47x: allow kernel to be loaded in higher physical memory
The 44x code (which is shared by 47x) assumes the available physical memory
begins at 0x00000000.  This is not necessarily the case in an AMP
environment.

Support CONFIG_RELOCATABLE for 476 in order to allow the kernel to be
loaded into a higher memory range.

ff56535d29 powerpc: Restore some misc devices to our configs
Uwe Kleine-König reported:

	while working on an defconfig (arm/mx27) I noticed that just updating
	it[1] results in removing CONFIG_EEPROM_AT24=y.  The reason is that
	since commit

		v2.6.36-5965-g5f2365d (misc devices: do not enable by default)

	MISC_DEVICES isn't enabled anymore by default.  So all defconfigs that
	have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
	MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
	problem.

This restores those misc devices to the powerpc defconfigs.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
