If IRQ balancing is used on a multicore ARM system, PMU interrupt
lines may be relocated onto CPUs other than the one causing the
counter overflow. This can result in misattribution of events to
the wrong core and, in the case that the CPU handling the interrupt
has not experience counter overflow, the interrupt can be disabled
because the handler returns IRQ_NONE.

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT,
PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining
arch_has_single_step in <asm/ptrace.h> and implementing the
user_enable_single_step and user_disable_single_step functions, which also
causes the breakpoint information to be cleared on fork, which could be
considered a bug fix.
Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which
it previously wasn't and the single stepping disable only happens if the
tracee process isn't a zombie yet, which is consistent with all
architectures using the modern ptrace code.

Add a generic implementation of the ipc demultiplexer syscall. Except for
s390 and sparc64 all implementations of the sys_ipc are nearly identical.
There are slight differences in the types of the parameters, where mips
and powerpc as the only 64-bit architectures with sys_ipc use unsigned
long for the "third" argument as it gets casted to a pointer later, while
it traditionally is an "int" like most other paramters. frv goes even
further and uses unsigned long for all parameters execept for "ptr" which
is a pointer type everywhere. The change from int to unsigned long for
"third" and back to "int" for the others on frv should be fine due to the
in-register calling conventions for syscalls (we already had a similar
issue with the generic sys_ptrace), but I'd prefer to have the arch
maintainers looks over this in details.
Except for that h8300, m68k and m68knommu lack an impplementation of the
semtimedop sub call which this patch adds, and various architectures have
gets used - at least on i386 it seems superflous as the compat code on
x86-64 and ia64 doesn't even bother to implement it.

The MsBSP register cache will never have any error/status flags set, since
these flags are never written to the reg_cache. So it is kind of not
necessary to clear these flags, which are actually always 0.
In other words, clearing the status/error flags are not necessary, since the
reg_cache will never got these bits set. We can just write back the
register content from the cache as it is when clearing an error condition.

When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4
will be true and prevent included code from building/running for
OMAP2/3 as well.
This problem exists in io.c where some hwmod/PM/SDRC init code is
prevented from running even on OMAP2/3 when OMAP4 is included in a
multi-OMAP build.
A quick glance suggests that this #ifndef is no longer needed in most
of the cases. In the remaining cases, the function is wrapped with
"if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized
out for OMAP4-only builds.
Note that this is only a short-term fix. Longer-term, OMAP4
needs to create init functions for SDRC and hwmod late-init.

Currently if omap2420 is defined but not omap2430, cpu_is_omap2430()
is still defined as a macro, instead of #define'd to zero. This
results in conditional cpu_is_omap2430() code still being compiled,
and leads to possible compile/link errors. In particular for hwmod
init.
To fix, add extra #ifdefs to CPU check macros to ensure that the
is_omap* macros are zero for each OMAP2 if they are not configured
into the kernel.

This patch follows the commit be093beb60
by Russell King:
OMAP wishes to pass state to the boot loader upon reboot in order
to instruct it whether to wait for USB-based reflashing or not.
There is already a facility to do this via the reboot() syscall,
except we ignore the string passed to machine_restart().
The patch adds the missing parameter to omap1_arch_reset() and
omap_prcm_arch_reset(), and modifies the latter to pass the reboot
command parameter to the boot loader instead of reboot mode (which is
for kernel internal use only and cannot be modified by the userspace).

The omap_serial_early_init prints the following errors:
Could not get uart4_ick
Could not get uart4_fck
because all the uarts available in omap_uart[] will be initialized.
Only omap4430 and omap3630 have 4 uarts at the moment.
This patch reduces the number of uarts when cpu is not omap4430 or
omap3630.

While waiting for the related USB patch, fix compile by enabling
it in the defconfigs. As discussed at:
http://thread.gmane.org/gmane.linux.usb.general/27432/focus=4460
Otherwise we'll get errors like:

Recent DMA API changes broke compile for tusb6010. While
testing the fixes for tusb6010, I had to update the n8x0
defconfig quite a bit. Might as well merge it while at it
to make it more usable as we're using this to test the
multi-omap booting between V6 and V7 ARMs.
Also, anybody using n8x0 with a current kernel will most
likely want to mount root on the MMC instead of the onenand
to keep the Maemo install intact.
Enable I2C, REGULATOR, MMC, MFD, PM, and USB. Also change the root
to /dev/mmcblk0p2 instead of the onenand.

the early_param() call in board-omap3touchbook.c expands to:
static const char __setup_str_early_touchbook_revision[]
__section(.init.rodata) _aligned(1) = tbr;
[...]
and we have a non-const variable being added to the
same section:
static struct ehci_hcd_omap_platform_data ehci_pdata
__section(.init.rodata);
because of that, gcc generates a section type conflict
which can (and actually should) be avoided by marking
const every variable marked with __initconst.
This patch fixes that for the ehci_hdc_omap_platform_data.

This makes it easier to extend perf_sample_data and fixes a bug on arm
and sparc, which failed to set ->raw to NULL, which can cause crashes
when combined with PERF_SAMPLE_RAW.
It also optimizes PowerPC and tracepoint, because the struct
initialization is forced to zero out the whole structure.

A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the

unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

pxa_camera init() callback is sometimes abused to setup MFP for PXA CIF, or
even to request GPIOs to be used by the camera *sensor*. These initializations
can be performed statically in machine init functions.
The current semantics for this init() callback is ambiguous anyways, it is
invoked in pxa_camera_activate(), hence at device node open, but its users use
it like a generic initialization to be done at module init time (configure
MFP, request GPIOs for *sensor* control).

Commit 2552fc2 changed the way the decompressor decides if it is safe
to decompress the kernel directly to its final location. Unfortunately,
it took the top of the compressed data as being the stack pointer,
which it is for ROM=n cases. However, for ROM=y, the stack pointer
is not relevant, and results in the wrong answer.
Fix this by explicitly storing the end of the biggybacked data in the
decompressor, and use that to calculate the compressed image size.

We used to build decompressors with -Dstatic= to avoid any local data
being generated. The problem is that local data generates GOTOFF
relocations, which means we can't relocate the data relative to the
text segment.
Global data, on the other hand, goes through the GOT, and can be
relocated anywhere.
Unfortunately, with the new decompressors, this presents a problem
since they declare static data within functions, and this leads to
stack overflow.
Fix this by separating out the decompressor code into a separate file,
and removing 'static' from BSS data in misc.c.
Also, discard the .data section - this means that should we end up
with read/write initialized data, the decompressor will fail to link
and the problem will be obvious.

Simplify the code in the omap2_clk_disable() and omap2_clk_enable()
functions, reducing levels of indentation. This makes the code easier
to read. Add some additional debugging pr_debug()s here also to help
others understand what is going on.
Revise the omap2_clk_disable() logic so that it now attempts to
disable the clock's clockdomain before recursing up the clock tree.
Simultaneously, ensure that omap2_clk_enable() is called on parent
clocks first, before enabling the clockdomain. This ensures that a
parent clock's clockdomain is enabled before the child clock's
clockdomain. These sequences should be the inverse of each other.
Revise the omap2_clk_enable() logic so that it now cleans up after
itself upon encountering an error. Previously, an error enabling a
parent clock could have resulted in inconsistent usecounts on the
enclosing clockdomain.
Remove the trivial _omap2_clk_disable() and _omap2_clk_enable() static
functions, and replace it with the clkops calls that they were
executing.
For all this to work, the clockdomain omap2_clkdm_clk_enable() and
omap2_clkdm_clk_disable() code must not return an error on clockdomains
without CLKSTCTRL registers; so modify those functions to simply return 0
in that case.
While here, add some basic kerneldoc documentation on both functions,
and get rid of some old non-CodingStyle-compliant comments that have
existed since the dawn of time (at least, the OMAP clock framework's
time).

Add support for categorizing and iterating over hardware IP blocks by

The OMAP hwmod core code is intended to use SoC IP block description
structures that are autogenerated from TI's OMAP hardware database.
Currently the hwmod code uses clkdev device + connection addressing to
identify clocks. This causes problems in the hwmod autogeneration
process, since the TI hardware database doesn't use platform_device or
clkdev addressing; it uses a single clock signal name string, which
tends to bear some resemblance to what is used in the OMAP TRMs. This
patch converts the hwmod code and existing data to use omap_clk_get_by_name(),
introduced in the previous patch.
