While the tracer accesses ptrace breakpoints, the child task may
concurrently exit due to a SIGKILL and thus release its breakpoints
at the same time. We can then dereference some freed pointers.
To fix this, hold a reference on the child breakpoints before

Several Davinci platforms select the I2C EEPROM support, but don't
select I2C support. This causes I2C EEPROM support to be built into
the kernel, but I2C support may not be configured to be built in.
This leads to linker errors due to missing I2C symbols.
Arrange for I2C to be selected whenever EEPROM_AT24 is selected.

As per OMAP3 erratum (i671), ROM code adds extra latencies while
restoring CM_AUTOIDLE_PLL register, if AUTO_PERIPH_DPLL is equal to 1.
This patch stores 0's in scratchpad content area corresponding to
AUTO_PERIPH_DPLL, to prevent ROM code to try to lock per DPLL, since
it won't respect proper programing scheme.
This register is then stored in prcm context. The saving and restore
is now done by kernel side.
Here follow the erratum description
DESCRIPTION
After OFF mode transition, among many restorations, the ROM Code restores the
CM_AUTOIDLE_PLL register, and after that, it tries to relock the PER DPLL.
In case the restoration data stored in scratchpad memory contains a field
CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL = 1, then the way the ROM Code restores and
locks the PER DPLL does not respect the PER DPLL programming scheme.
In that case, the DPLL might not lock. Meanwhile, when trying to lock the PER
DPLL, the ROM Code does not hang. Only extra latencies are introduced at
wake-up.
WORKAROUND
When saving the context-restore structure in scratchpad memory, in order to
respect the PER DPLL programming scheme, it is advised to store 0 in the
CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL field of the saved structure.
After wake-up, the application should store in CM_AUTOIDLE_PLL register the
right desired value.

DSS driver has used fck and ick clocks on OMAP2/3 to get DSS HW up and
running, and also to get the pixel clock's source clock rate from the
fck.
On OMAP4 the clock data is set up in a different way, as there's no ick,
dss_fck points to a fake clock which just affects DSS's MODULEMODE, and
dss_dss_clk if the DSS_FCK.
>From DSS driver's point of view the dss_fck sounds like an ick, and
dss_dss_clk is the fck. While this is not entirely correct from HW point
of view, especially for the ick, configuring the clock aliases that way
makes DSS "just work" with OMAP4's clock setup.
In the (hopefully near) future DSS driver will be reworked to use
pm_runtime support which should clean up the clock code.

Directives such as .long and .word do not magically cause the
assembler location counter to become aligned in gas. As a
result, using these directives in code sections can result in
misaligned data words when building a Thumb-2 kernel
(CONFIG_THUMB2_KERNEL).
This is a Bad Thing, since the ABI permits the compiler to
assume that fundamental types of word size or above are word-
aligned when accessing them from C. If the data is not really
word-aligned, this can cause impaired performance and stray
alignment faults in some circumstances.
In general, the following rules should be applied when using
data word declaration directives inside code sections:
* .quad and .double:
.align 3
* .long, .word, .single, .float:
.align (or .align 2)
* .short:
No explicit alignment required, since Thumb-2
instructions are always 2 or 4 bytes in size.

For the lcdif clock get_rate looks as follows:
read div from HW_CLKCTRL_DIS_LCDIF.DIV
return clk_get_rate(clk->parent) / div
with clk->parent being ref_pix_clk on my system.
ref_pix_clk's rate depends on HW_CLKCTRL_FRAC1.PIXFRAC.
The set_rate function for lcdif does:
parent_rate = clk_get_rate(clk->parent);
based on that calculate frac and div such that
parent_rate * 18 / frac / div is near the requested rate.
HW_CLKCTRL_FRAC1.PIXFRAC is updated with frac
HW_CLKCTRL_DIS_LCDIF.DIV is updated with div
For this calculation to be correct parent_rate needs to be
initialized not with the clock rate of lcdif's parent (i.e. ref_pix) but
that of its grandparent (i.e. ref_pix' parent == pll0_clk).
The obvious downside of this patch is that now set_rate(lcdif) changes
its parent's rate, too. Still this is better than a wrong rate.

Commit a737823d ("ARM: perf: ensure overflows aren't missed due to IRQ
latency") changed the way that event deltas are calculated on overflow
so that we don't miss events when the new count value overtakes the
previous one.
Unfortunately, we forget to count the event that passes through zero so
we end up being off by 1. This patch adds on the correction.

The DBGVCR, used for configuring vector catch debug events, is UNKNOWN

This patch adds the zeroing code to the debug reset path.

Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h

CONFIG_PM is now set whenever we support either runtime PM in addition

So, switch this code to use CONFIG_PM_SLEEP rather than CONFIG_PM to

- commit eead4d5c63 ("powerpc: qe_ic: Rename get_irq_desc_data and

irq_desc_get_handler_data() instead of the legacy (and no longer
existing) get_irq_desc_data.
- commit d4db35e8dc ("powerpc/qe_ic: Fix another breakage from the
irq_data conversion") used irq_desc_get_chip_data() instead.
According to Thomas, the former is the correct direct conversion, but it
does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c
seems to initialize both to the same thing), and the chip data in some
ways is the more logical. Somebody should really decide on one of the
other.
This merge picks irq_desc_get_handler_data() as the straightforward pure
conversion to new names, as per Thomas.

The inline assembly differences for v6 vs. v7 are purely
optimizations. On a v7 processor, an mrc with the pc sets the
condition codes to the 28-31 bits of the register being read. It
just so happens that the TX/RX full bits the DCC support code is
testing for are high enough in the register to be put into the
condition codes. On a v6 processor, this "feature" isn't
implemented and thus we have to do the usual read, mask, test
operations to check for TX/RX full. Thus, we can drop the v7
implementation and just use the v6 implementation for both.

The Rn value from the emulation is unconditionally written back;
this is fine as long as Rn != PC because in that case, even if the
instruction isn't a write back instruction, it will only result in the
same value being written back.
In case Rn == PC, then the emulated instruction doesn't have the
actual PC value in Rn but an adjusted value; when this is written
back, it will result in the PC being incorrectly updated.
An altenative solution would be to check bits 24 and 22 to see whether
the instruction actually is a write back instruction or not. I think
it's enough to check whether Rn != PC, because:
- it's looks cheaper than the alternative
- to my understaning it's not permitted to update the PC with a write
back instruction, so we don't lose any ability to emulate legal
instructions.
- in case of writing back for non write back instructions where Rn != PC, it doesn't matter because the values are the same.
Regarding the second point above, it would possibly be prudent to add
some checking to prep_emulate_ldr_str(), so that instructions with
both write back and Rn == PC would be rejected.

handle_prio_irq is almost identical with handle_fasteoi_irq. The
subtle differences are
1) The handler checks for IRQ_DISABLED after the device handler has
been called. In case it's set it masks the interrupt.
2) When the handler sees IRQ_DISABLED on entry it masks the interupt
in the same way as handle_fastoei_irq, but does not set the
IRQ_PENDING flag.
3) Instead of gracefully handling a recursive interrupt it crashes the
kernel.
#1 is just relevant when a device handler calls disable_irq_nosync()
and it does not matter whether we mask the interrupt right away or
not. We handle lazy masking for disable_irq anyway, so there is no
real reason to have this extra mask in place.
#2 will prevent the resend of a pending interrupt, which can result in
lost interrupts for edge type interrupts. For level type interrupts
the resend is a noop in the generic code. According to the
datasheet all interrupts are level type, so marking them as such
will result in the exact same behaviour as the private
handle_prio_irq implementation.
#3 is just stupid. Crashing the kernel instead of handling a problem
gracefully is just wrong. With the current semantics- all handlers
run with interrupts disabled - this is even more wrong.
Rename ack to eoi, remove the unused mask_ack, switch to
handle_fasteoi_irq and remove the private function.

If a counter overflows during a perf stat profiling run it may overtake
the last known value of the counter:
0 prev new 0xffffffff
|----------|-------|----------------------|
In this case, the number of events that have occurred is
(0xffffffff - prev) + new. Unfortunately, the event update code will
not realise an overflow has occurred and will instead report the event
delta as (new - prev) which may be considerably smaller than the real
count.
This patch adds an extra argument to armpmu_event_update which indicates
whether or not an overflow has occurred. If an overflow has occurred
then we use the maximum period of the counter to calculate the elapsed
events.

To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.
In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.
SDHI registers occupy only a 0x100 byte large window, not 0x200 byte.

Commit ddd588b5dd ("oom: suppress nodes that are not allowed from
meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which
resulted in build warnings on all architectures that implement their own
versions of show_mem():
lib/lib.a(show_mem.o): In function `show_mem':
show_mem.c:(.text+0x1f4): multiple definition of `show_mem'
arch/sparc/mm/built-in.o:(.text+0xd70): first defined here
The fix is to remove __show_mem() and add its argument to show_mem() in
all implementations to prevent this breakage.
Architectures that implement their own show_mem() actually don't do
anything with the argument yet, but they could be made to filter nodes
that aren't allowed in the current context in the future just like the
generic implementation.

Percpu allocator honors alignment request upto PAGE_SIZE and both the
percpu addresses in the percpu address space and the translated kernel
addresses should be aligned accordingly. The calculation of the
former depends on the alignment of percpu output section in the kernel
image.
The linker script macros PERCPU_VADDR() and PERCPU() are used to
define this output section and the latter takes @align parameter.
Several architectures are using @align smaller than PAGE_SIZE breaking
percpu memory alignment.
This patch removes @align parameter from PERCPU(), renames it to
PERCPU_SECTION() and makes it always align to PAGE_SIZE. While at it,
add PCPU_SETUP_BUG_ON() checks such that alignment problems are
reliably detected and remove percpu alignment comment recently added
in workqueue.c as the condition would trigger BUG way before reaching
there.
For um, this patch raises the alignment of percpu area. As the area
is in .init, there shouldn't be any noticeable difference.
This problem was discovered by David Howells while debugging boot
failure on mn10300.

The Xen PV drivers in a crashed HVM guest can not connect to the dom0
backend drivers because both frontend and backend drivers are still in
connected state. To run the connection reset function only in case of a
crashdump, the is_kdump_kernel() function needs to be available for the PV
driver modules.
Consolidate elfcorehdr_addr, setup_elfcorehdr and saved_max_pfn into
kernel/crash_dump.c Also export elfcorehdr_addr to make is_kdump_kernel()
usable for modules.
Leave 'elfcorehdr' as early_param(). This changes powerpc from __setup()
to early_param(). It adds an address range check from x86 also on ia64

minix bit operations are only used by minix filesystem and useless by
other modules. Because byte order of inode and block bitmaps is different
on each architecture like below:
m68k:
big-endian 16bit indexed bitmaps
h8300, microblaze, s390, sparc, m68knommu:
big-endian 32 or 64bit indexed bitmaps
m32r, mips, sh, xtensa:
big-endian 32 or 64bit indexed bitmaps for big-endian mode
little-endian bitmaps for little-endian mode
Others:
little-endian bitmaps
In order to move minix bit operations from asm/bitops.h to architecture
independent code in minix filesystem, this provides two config options.
CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
m32r, mips, sh, xtensa). The architectures which always use little-endian
bitmaps do not select these options.
Finally, we can remove minix bit operations from asm/bitops.h for all
architectures.

The current Versatile Express BSP defines the MACHINE_START macro
in the core tile code.
This patch moves this into the generic board code and introduces a
method for determining the current tile at runtime, allowing the
Kernel to have support for multiple tiles compiled in. Tile-specific
functions are executed via a descriptor struct containing the correct
implementations for the current tile.

(omap: gpmc: enable irq mode in gpmc) enabled interrupts for
GPMC (General Purpose Memory Controller). However, looks like
this patch only works on omap3. Fix the issues to avoid warnings
on omap4 during the boot.
GPMC: number of chip select is 8, CS0 to CS7. One less IRQ
allocated throws below warning at boot:

the pandaboard does not use the VUSIM or VAUX1 power regulators on the TWL6030
and are left floating. if the VUSIM and VAUX1 power regulators are initilized,
noise on the unloaded regulators generates an overcurrent interrupt causing the
system to power down. this patch removes the initialization of the unused power
regulators of VUSIM and VAUX1.

Adding DVI support to OMAP4 PandaBoard.
PandaBoard uses TFP410 DVI Framer chip
http://focus.ti.com/lit/ds/symlink/tfp410.pdf
The TFP410 gets its power enable and display data over GPIO lines muxed
in from OMAP4430. PandaBoard supports other LCD displays through
expansion
connectors, following board rework. This will disable the DVI interface.
However, the existing mux settings remain the same
PandaBoard additionally supports display over HDMI interface. It is
mutually exclusive to display over DVI. Hence the mux settings need to
be
configured seperately, as and when HDMI is enabled
Also, I2C3 bus used for reading EDID data from DVI Monitors is
registered here. Since the design is similar to BeagleBoard, the code
for the same is taken from the kernel.org commit e3333f48dd
(omap: Adding beagle i2c eeprom driver to read EDID)

On Harmony board PCI-e subsystem can be enabled only after certain
voltage regulators are on. One of the regulators is an internal
regulator on the PMIC and another one is controlled by a PMIC GPIO.
Addition of the voltage control to the Harmony PCI-e initialization
allows booting of kernel with CONFIG_TEGRA_PCI even if the PMIC driver
is not loaded. In this case the PCI-e initialization will fail
gracefully intead of hanging the system.

The MUSB driver doesn't see its platform device on DM644x EVM board anymore
since commit 73b089b052 (usb: musb: split davinci
to its own platform_driver) because the new probe is called as subsys_initcall()
now, and the device is registered later than that by the board code. Move the
registration to davinci_evm_init() -- it's safe to do so because the MUSB core
device still gets initialized as fs_initcall() -- which is late enough for the
I2C GPIO expander (which controls VBUS) to be initialized.

This patch includes the implementation of the clock gating
for System MMU. Initially, all System MMUs are not asserted
the system clock. Asserting the system clock to a System MMU
is enabled only when s5p_sysmmu_enable() is called. Likewise,
it is disabled only when s5p_sysmmu_disable() is called.
Therefore, clock gating on System MMUs are still invisible to
the outside of the System MMU driver.

Some chained IRQ handlers are written to cope with primary chips of
potentially different flow types. Whether this a sensible thing to do
is a point of contention.
This patch introduces entry/exit functions for chained handlers which
infer the flow type of the primary chip as fasteoi or level-type by
checking whether or not the ->irq_eoi function pointer is present and
calling back to the primary chip as necessary. Other methods of flow
control are not considered.

commit 522d7dec(futex: Remove redundant pagefault_disable in
futex_atomic_cmpxchg_inatomic()) added a bogus comment.
/* Note that preemption is disabled by futex_atomic_cmpxchg_inatomic
* call sites. */
Bogus in two aspects:
1) pagefault_disable != preempt_disable even if the mechanism we use
is the same
2) we have a call site which deliberately does not disable pagefaults
as it wants the possible fault to be handled - though that has been
changed for consistency reasons now.
Sigh. I really should have seen that when committing the above. :(

Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according
to input 'da' address when mapping memory:
da == 0: IOVMF_DA_ANON
da != 0: IOVMF_DA_FIXED
It prevents IOMMU to map first page with fixed 'da'. To avoid such
issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now
come from the user throught 'flags' parameter when mapping memory.
As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON
can be removed. The driver will now check internally if IOVMF_DA_FIXED
is set or not.

Setting pinmux alternative C for a GPIO pin is actually not

and since the combined result will take effect for intermediate
