e22ba7e381 [POWERPC] ps3: multiplatform build fixes
A few code paths need to check whether or not they are running
on the PS3's LV1 hypervisor before making hcalls. This introduces
a new firmware feature bit for this, FW_FEATURE_PS3_LV1.

Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.

The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
if we get oprofile support for PS3.

3d1ea8e8cb [POWERPC] Remove ioremap64 and fixup_bigphys_addr
In order to suppose platforms with devices above 4Gb on 32 bits platforms
with a >32 bits physical address space, we used to have a special ioremap64
along with a fixup routine fixup_bigphys_addr.

This shouldn't be necessary anymore as struct resource now supports 64 bits
addresses even on 32 bits archs. This patch enables that option when
CONFIG_PHYS_64BIT is set and removes ioremap64 and fixup_bigphys_addr.

This is a preliminary work for the upcoming merge of 32 and 64 bits io.h

This patch implements a workaround for a Spider PCI host bridge bug

4cb3cee03d [POWERPC] Allow hooking of PCI MMIO & PIO accessors on 64 bits
This patch reworks the way iSeries hooks on PCI IO operations (both MMIO
and PIO) and provides a generic way for other platforms to do so (we
have need to do that for various other platforms).

While reworking the IO ops, I ended up doing some spring cleaning in
io.h and eeh.h which I might want to split into 2 or 3 patches (among
others, eeh.h had a lot of useless stuff in it).

A side effect is that EEH for PIO should work now (it used to pass IO
ports down to the eeh address check functions which is bogus).

Also, new are MMIO "repeat" ops, which other archs like ARM already had,
and that we have too now: readsb, readsw, readsl, writesb, writesw,
writesl.

In the long run, I might also make EEH use the hooks instead
of wrapping at the toplevel, which would make things even cleaner and
relegate EEH completely in platforms/iseries, but we have to measure the
performance impact there (though it's really only on MMIO reads)

Since I also need to hook on ioremap, I shuffled the functions a bit
there. I introduced ioremap_flags() to use by drivers who want to pass
explicit flags to ioremap (and it can be hooked). The old __ioremap() is
still there as a low level and cannot be hooked, thus drivers who use it
should migrate unless they know they want the low level version.

The patch "arch provides generic iomap missing accessors" (should be
number 4 in this series) is a pre-requisite to provide full iomap
API support with this patch.

4c9d2800be [POWERPC] Generic OF platform driver for PCI host bridges.
When enabled in Kconfig, it will pick up any of_platform_device
matching it's match list (currently type "pci", "pcix", "pcie",
or "ht" and setup a PHB for it.

Platform must provide a ppc_md.pci_setup_phb() for it to work
(for doing the necessary initialisations specific to a given PHB
like setting up the config space ops).

It's currently only available on 64 bits as the 32 bits PCI code
can't quite cope with it in it's current form. I will fix that
later.

Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.

Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:

"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support.  Qe_lib is used by
QE device drivers such as ucc_geth driver.

This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.

v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.

v3: Address comments from Kumar;  Update definition of several
device tree nodes;  Copyright style change."

In addition, the following changes have been made:

o removed typedefs
o uint -> u32 conversions
o removed following defines:
  QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
  BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
  because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues
o marked ioregs as __be32/__be16
o removed platform_device code and redundant get_qe_base()
o removed redundant comments
o added cpu_relax() to qe_reset

3a872d89ba [PATCH] Kprobes: Make kprobe modules more portable
In an effort to make kprobe modules more portable, here is a patch that:

o Introduces the "symbol_name" field to struct kprobe.
  The symbol->address resolution now happens in the kernel in an
  architecture agnostic manner. 64-bit powerpc users no longer have
  to specify the ".symbols"
o Introduces the "offset" field to struct kprobe to allow a user to
  specify an offset into a symbol.
o The legacy mechanism of specifying the kprobe.addr is still supported.
  However, if both the kprobe.addr and kprobe.symbol_name are specified,
  probe registration fails with an -EINVAL.
o The symbol resolution code uses kallsyms_lookup_name(). So
  CONFIG_KPROBES now depends on CONFIG_KALLSYMS
o Apparantly kprobe modules were the only legitimate out-of-tree user of
  the kallsyms_lookup_name() EXPORT. Now that the symbol resolution
  happens in-kernel, remove the EXPORT as suggested by Christoph Hellwig
o Modify tcp_probe.c that uses the kprobe interface so as to make it
  work on multiple platforms (in its earlier form, the code wouldn't
  work, say, on powerpc)

7233593b78 [POWERPC] Support for "weird" MPICs and fixup mpc7448_hpc2
This adds a new hardware information table for mpic. This enables
the mpic code to deal with mpic controllers with different register
layouts and hardware behaviours.

This introduces CONFIG_MPIC_WEIRD.  For boards with non standard mpic
controllers, select CONFIG_MPIC_WEIRD and add its hardware information
in the mpic_infos[] array.

TSI108/109 PIC takes the first index of weird hardware information
table.  :)  The table can be extended. The Tsi108/109 PIC looks like
standard OpenPIC but, in fact, is different in register mapping and
behavior.

The patch does not affect the behavior of standard mpic.  If
CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to
the current code.

[benh@kernel.crashing.org:
This patch is a slightly cleaned up version of Zang Roy's support for
the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new
version of the type macros and changes the way MPIC is selected in
Kconfig to better match what is done for other system devices.

cc57637b0b [PATCH] solve config broken: undefined reference to `online_page'
Memory hotplug code of i386 adds memory to only highmem.  So, if
CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set.
Otherwise, it causes compile error.

In addition, many architecture can't use memory hotplug feature yet.  So, I
introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG.

The todc code from arch/ppc supports many todc/rtc chips and is needed
in arch/powerpc.  This patch adds the todc code to arch/powerpc.

c01ea72a3b [POWERPC] spufs: split the Cell BE support into generic and platform dependant parts
Creates new config variables PPC_CELL_NATIVE and PPC_IBM_CELL_BLADE.
The existing CONFIG_PPC_CELL is now used to denote the generic
Cell processor support.

PPC_CELL = make descends into platforms/cell
PPC_CELL_NATIVE = add bare metal support
PPC_IBM_CELL_BLADE = add blade device drivers, etc.

Also renames spu_priv1.c to spu_priv1_mmio.c.
