667f390bee ARM: 6910/1: MTD: physmap: let set_vpp() pass a platform_device instead of a map_info
The set_vpp() method provided by physmap passes a map_info back to
the platform code, which has little relevance as far as the platform
is concerned (this parameter is completely unused).

Instead, pass the platform_device, which can be used in the pismo
driver to retrieve some important information in a nicer way, instead
of the hack that was in place.

The empty set_vpp function in board-at572d940hf_ek.c is left untouched,
as the board/SoC is scheduled for removal.

d286a43aa2 ARM: mx3: make ioremap quirk ready for multi-SoC kernels
To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image
the ioremap quirk needs a runtime check.

While touching this code make the comment more understandable by adding
a sentence from the commit log that introduced it
(eadefef ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)).

As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h
was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which
#includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros
needs to be included before mach/mx27.h and mach/mx31.h.)

91350f6677 ARM: mxc: don't use the symbols in the CPU family choice to select others
The symbols in this choice should only be used to select between the
available machines that can be built into a single kernel. As these sets
(will) differ e.g. depending on ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR
letting them select other symbols makes the logic more complex and needs
to duplicate some things. So let the machines select the corresponding
symbols (indirectly via SOC_XYZ).

18879e13b1 ARM: imx51: use platform id 2 for imx51-cspi
The platform id is used to determine the spi bus number, so it should
better be different to the ids used for imx51-ecspi.  Otherwise it's not
possible to use both devices "imx51-cspi.0" and "imx51-ecspi.0".

Alternative approaches are to use dynamic bus numbering as offered by
the spi framework or let the machine code set the bus number.  The
downside of both possibilities is that the bus number isn't fixed for
the same busses on different machines using i.MX51.

afa77ef30e ARM: mx3: dynamically allocate "ipu-core" devices
... together with the related devices "mx3_camera" and "mx3_sdc_fb".

"mx3_camera" doesn't fit the scheme of the other devices that just are
allocated and registered in a single function because it needs additional
care to get some dmaable memory. So currently imx31_alloc_mx3_camera
duplicates most of imx_add_platform_device_dmamask, but I'm not sure it's
worth to split the latter to be able to reuse more code.

This gets rid of mach-mx3/devices.[ch] and so several files need to be
adapted not to #include devices.h anymore.

It's not allowed to create an alias of system RAM for DMA.  So the memory
used must not be allocated using dma_alloc_coherent but has to be reserved
before using memblock routines.

There is no need to memzero the buffer because dma_alloc_coherent zeros
the memory for us.

This was very useful in finding a number of sysfs and driver core bugs
in the 2.5 and early 2.6 development days, but it has been a number of
years since this file has actually helped in debugging anything that
couldn't also be trivially determined from the stack traceback.

So it's time to delete the line.  This is good as we need all the space

2af68df02f ARM: 6892/1: handle ptrace requests to change PC during interrupted system calls
GDB's interrupt.exp test cases currenly fail on ARM.  The problem is how do_signal
handled restarting interrupted system calls:

The entry.S assembler code determines that we come from a system call; and that
information is passed as "syscall" parameter to do_signal.  That routine then
calls get_signal_to_deliver [*] and if a signal is to be delivered, calls into
handle_signal.  If a system call is to be restarted either after the signal
handler returns, or if no handler is to be called in the first place, the PC
is updated after the get_signal_to_deliver call, either in handle_signal (if
we have a handler) or at the end of do_signal (otherwise).

Now the problem is that during [*], the call to get_signal_to_deliver, a ptrace
intercept may happen.  During this intercept, the debugger may change registers,
including the PC.  This is done by GDB if it wants to execute an "inferior call",
i.e. the execution of some code in the debugged program triggered by GDB.

To this purpose, GDB will save all registers, allocate a stack frame, set up
PC and arguments as appropriate for the call, and point the link register to
a dummy breakpoint instruction.  Once the process is restarted, it will execute
the call and then trap back to the debugger, at which point GDB will restore
all registers and continue original execution.

This generally works fine.  However, now consider what happens when GDB attempts
to do exactly that while the process was interrupted during execution of a to-be-
restarted system call:  do_signal is called with the syscall flag set; it calls
get_signal_to_deliver, at which point the debugger takes over and changes the PC
to point to a completely different place.  Now get_signal_to_deliver returns
without a signal to deliver; but now do_signal decides it should be restarting
a system call, and decrements the PC by 2 or 4 -- so it now points to 2 or 4
bytes before the function GDB wants to call -- which leads to a subsequent crash.

To fix this problem, two things need to be supported:
- do_signal must be able to recognize that get_signal_to_deliver changed the PC
  to a different location, and skip the restart-syscall sequence
- once the debugger has restored all registers at the end of the inferior call
  sequence, do_signal must recognize that *now* it needs to restart the pending
  system call, even though it was now entered from a breakpoint instead of an
  actual svc instruction

This set of issues is solved on other platforms, usually by one of two
mechanisms:

- The status information "do_signal is handling a system call that may need
  restarting" is itself carried in some register that can be accessed via
  ptrace.  This is e.g. on Intel the "orig_eax" register; on Sparc the kernel
  defines a magic extra bit in the flags register for this purpose.
  This allows GDB to manage that state: reset it when doing an inferior call,
  and restore it after the call is finished.

- On s390, do_signal transparently handles this problem without requiring
  GDB interaction, by performing system call restarting in the following
  way: first, adjust the PC as necessary for restarting the call.  Then,
  call get_signal_to_deliver; and finally just continue execution at the
  PC.  This way, if GDB does not change the PC, everything is as before.
  If GDB *does* change the PC, execution will simply continue there --
  and once GDB restores the PC it saved at that point, it will automatically
  point to the *restarted* system call.  (There is the minor twist how to
  handle system calls that do *not* need restarting -- do_signal will undo
  the PC change in this case, after get_signal_to_deliver has returned, and
  only if ptrace did not change the PC during that call.)

Because there does not appear to be any obvious register to carry the
syscall-restart information on ARM, we'd either have to introduce a new
artificial ptrace register just for that purpose, or else handle the issue
transparently like on s390.  The patch below implements the second option;
using this patch makes the interrupt.exp test cases pass on ARM, with no
regression in the GDB test suite otherwise.

9af386c8dc ARM: 6890/1: memmap: only free allocated memmap entries when using SPARSEMEM
The SPARSEMEM code allocates memmap entries only for sections which are
present (i.e. those which contain some valid memory). The membank checks
in free_unused_memmap do not take this into account and can incorrectly
attempt to free memory which is not allocated, resulting in a BUG() in
the bootmem code.

However, if memory is configured as follows:

    |<----section---->|<----hole---->|<----section---->|
    +--------+--------+--------------+--------+--------+
    | bank 0 | unused |              | bank 1 | unused |
    +--------+--------+--------------+--------+--------+

where a bank only occupies part of a section, the memmap allocated for
the remainder of the section *can* be freed.

This patch modifies the checks in free_unused_memmap so that only valid
memmap entries are considered for removal.

1a01753ed9 ARM: gic: use handle_fasteoi_irq for SPIs
Currently, the gic uses handle_level_irq for handling SPIs (Shared
Peripheral Interrupts), requiring active interrupts to be masked at
the distributor level during IRQ handling.

On a virtualised system, only the CPU interfaces are virtualised in
hardware. Accesses to the distributor must be trapped by the
hypervisor, adding latency to the critical interrupt path in Linux.

This patch modifies the GIC code to use handle_fasteoi_irq for handling
interrupts, which only requires us to signal EOI to the CPU interface
when handling is complete. Cascaded IRQ handling is also updated to use
the chained IRQ enter/exit functions to honour the flow control of the
parent chip.

Note that commit 846afbd1 ("GIC: Dont disable INT in ack callback")
broke cascading interrupts by forgetting to add IRQ masking. This is
no longer an issue because the unmask call is now unnecessary.

Tested on Versatile Express and Realview EB (1176 w/ cascaded GICs).

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols.  This usually means that no global variables can
be marked static unless they're also const.

To enforce this, suffice to fail the build whenever a private symbol
is allocated to .bss and list those symbols for convenience.

The user_stack and user_stack_end labels in head.S were converted into
non exported symbols to remove false positives.

adcc25915b ARM: zImage: make sure not to relocate on top of the relocation code
If the zImage load address is slightly below the relocation address,
there is a risk for the copied data to overwrite the copy loop or
cache flush code that the relocation process requires.  Always
bump the relocation address by the size of that code to avoid this
issue.

Noticed by Tony Lindgren <tony@atomide.com>.

While at it, let's start the copy from the restart symbol which makes
the above code size computation possible by the assembler directly
(same sections), given that we don't need to preserve the code before
that point anyway. And therefore we don't need to carry the _start
pointer in r5 anymore.

7c2527f0c4 ARM: zImage: Fix bad SP address after relocating kernel
Otherwise cache_clean_flush can overwrite some of the relocated
area depending on where the kernel image gets loaded. This fixes
booting on n900 after commit 6d7d0ae515
(ARM: 6750/1: improvements to compressed/head.S).

Thanks to Aaro Koskinen <aaro.koskinen@nokia.com> for debugging
the address of the relocated area that gets corrupted, and to

3bd2cbb955 ARM: zImage: make sure the stack is 64-bit aligned
With ARMv5+ and EABI, the compiler expects a 64-bit aligned stack so
instructions like STRD and LDRD can be used.  Without this, mysterious
boot failures were seen semi randomly with the LZMA decompressor.

While at it, let's align .bss as well.

2d06d8c49a [CPUFREQ] use dynamic debug instead of custom infrastructure
With dynamic debug having gained the capability to report debug messages
also during the boot process, it offers a far superior interface for
debug messages than the custom cpufreq infrastructure. As a first step,
remove the old cpufreq_debug_printk() function and replace it with a call
to the generic pr_debug() function.

How can dynamic debug be used on cpufreq? You need a kernel which has
CONFIG_DYNAMIC_DEBUG enabled.

To enabled debugging during runtime, mount debugfs and

$ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control

for debugging the complete "cpufreq" module. To achieve the same goal during
boot, append

	ddebug_query="module cpufreq +p"

as a boot parameter to the kernel of your choice.

For more detailled instructions, please see
Documentation/dynamic-debug-howto.txt

f295dc6874 ARM: mach-stmp378x: remove mach
This mach has not seen any updates since the initial inclusion besides
generic cleanup. Furthermore:

- The i.MX23 covered in mach-mxs is just a renamed version of the
  STMP378x.

- mach-stmp378x has a lot of reinvented interfaces, leaking all sorts of
  mach-related includes into the drivers. One example is the dmaengine
  which does not use the linux dmaengine-API but some privately exported
  symbols. So drivers cannot be reused. mach-mxs does it better.

- There is only one board defined (which I couldn't find any trace of
  despite being a development board). It has been converted to
  mach-mxs in a previous patch.

Since the only user of this mach was converted, it means that
mach-stmp378x can go.

7635965891 ARM: mach-stmp37xx: remove mach

  mach-related includes into the drivers. One example is the dmaengine
  which does not use the linux dmaengine-API but some privately exported

  does it better.

- It can be doubted that this worked at all. Check the DMA routines in
  stmp37xx.c for copy/paste bugs. A lot of APBX-related stuff is
  actually writing into registers for APBH.

- There is only one board defined (which I couldn't find any trace of
  despite being a development board). In this board, only two devices
  have resources, the debug uart and the application uart. Neither of
  those have the needed custom drivers merged (and never will). debug
  uart is amba-pl011 which has an in-kernel driver without the
  mach-specific-stuff. appuart has a driver which was introduced for
  mach-mxs, and this one is reusable for a properly done mach.

So, this single board registers only unsupported devices and the
generic code looks suspicious and has poor design. Delete this
stuff. If there is interest, it is wiser to restart using
mach-mxs.

a98253e800 ARM: mach-mxs: add stmp378x-devb
STMP378x and MX23 are the same and just relabeled. There is a
mach-stmp378x, however, it has a lot of reinvented interfaces, leaking
all sorts of mach-specific functions into the drivers. One example is
the dmaengine which does not use the linux dmaengine-API but some
privately exported symbols. This makes generic use of the drivers
impossible. mach-mxs does it better, so convert the board to mach-mxs.
After that, it is possible to delete all stmp-specific code which should
ease further ARM-consolidation.

Compile tested only due to no hardware (seems not available anymore).

When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does not
