ccac05152e ARM: Tegra: DMA: Fail safe if initialization fails
tegra_dma_init currently simply bails out early if any initialization fails.
This skips various data-structure initialization. In turn, this means that
tegra_dma_allocate_channel can still hand out channels. In this case, when
tegra_dma_free_channel is called, which calls tegra_dma_cancel, the walking
on ch->list will OOPS since the list's next/prev pointers may still be
NULL.

To solve this, add an explicit "initialized" flag, only set this once _init
has fully completed successfully, and have _allocate_channel refuse to hand
out channels if this is not set.

While at it, simplify _init:
* Remove redundant memsets
* Use bitmap_fill to mark all channels as in-use up-front, and remove
  some now-redundant bitmap initialization loops.
* Only mark a channel as free once all channel-related initialization has
  completed.

Finally, the successful exit path from _init always has ret==0, so just
hard-code that return. The error path still returns ret.

ddb7d5d80e ARM: Tegra: Rename clk_dev1/2 to cdev1/2
The ASoC machine driver was written assuming my previous patch to add
complete support for these clocks, which named them cdev1/2. Rename
the clocks to match that, to avoid churn in the ASoC driver.

This rename also makes the clocks more consistent with other Tegra
clocks irrespective of any of that.

dc54c23bb0 ARM: Tegra: Make tegra_dma_init a postcore_initcall
The following commit makes the Tegra APB DMA engine fail to initialize
correctly: 0cf6230af9
ARM: tegra: Move tegra_common_init to tegra_init_early

The reason is that tegra_init_early_ calls tegra_dma_init which calls
request_threaded_irq, which fails since the IRQ hasn't yet been marked
valid; that only happens in tegra_init_irq, which gets called after
tegra_init_early.

This used to work OK, since tegra_init_early was tegra_common_init, which
got called after tegra_init_irq, basically from the beginning of
tegra_harmony_init.

Solve this by converting tegra_dma_init to a postcore_initcall. This makes
it execute late enough that IRQs are marked valid, and avoids having to
add it back to every machine's init function.

97594b0f35 ARM: 6757/1: fix tlb.h induced linux/swap.h build failure
Commit

	06824ba (ARM: tlb: delay page freeing for SMP and ARMv7 CPUs)

introduced a build failure for builds with CONFIG_SWAP=n:

	In file included from arch/arm/mm/init.c:27:
	arch/arm/include/asm/tlb.h: In function 'tlb_flush_mmu':
	arch/arm/include/asm/tlb.h:101: error: implicit declaration of function 'release_pages'
	arch/arm/include/asm/tlb.h: In function 'tlb_remove_page':
	arch/arm/include/asm/tlb.h:165: error: implicit declaration of function 'page_cache_release'

as linux/swap.h doesn't include linux/pagemap.h but actually needs it
(see comments in linux/swap.h as to why this is.)

Fix that by #including <linux/pagemap.h> in <asm/pgalloc.h> as it's done
by x86.

ea68c00e26 OMAP2/3: clock: fix fint calculation for DPLL_FREQSEL
In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction
Feature", it is shown that the internal frequency is calculated by
CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is
already "N+1" since Linux is using the values to divide by. In the
technical reference manual, "N" is referring to the divider's register
value (0-127).

During power management testing, it was observed that programming the
wrong jitter correction value can cause the system to become unstable
and eventually crash.

421186e710 ARM: tegra: clock: Round rate before setting rate
Call the clock's round_rate op, if it exists, before calling
the set_rate op.  This will help later when dvfs is added,
dvfs needs to know what the final rate will be before the
frequency changes.

Also requires fixes to the round rate functions to ensure
calling round rate and then set rate will not cause the
frequency to be rounded down twice.  When picking clock
divider values, the clock framework picks the closest
frequency that is lower than the requested frequency.  If
the new frequency calculated from the divider value is
rounded down, and then passed to set_rate, it will get
rounded down again, possibly resulting in a frequency two
steps lower than the original requested frequency.

Fix the problem by rounding up when calculating the frequency
coming out of a clock divider, so if that frequency is
requested again, the same divider value will be picked.

dc810efb0c ARM: 6740/1: Place correctly notes section in the linker script
Commit 18991197b4 added --build-id
linker option when toolchain supports it. ARM one does, but for some
reason places the section at 0 when linker script doesn't mention it
explicitly.

The 1e621a8e37 worked around the problem
removing this section from binary image with explicit objcopy options,
but it still exists in vmlinux, confusing tools like debuggers and perf.

This problem was discussed here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
but the proposed changes to the linker script were substantial.

This patch simply places NOTES (36 bytes long, at least when compiled
with CodeSourcery toolchain) between data and bss, which seem to be
the right place (and suggested by the sample linker script in
include/asm-generic/vmlinux.lds.h).

It is enough to place it correctly in vmlinux (so debuggers are happy):

the list head will still point at it, yet the node's next/prev will
contain the list poison values. When the next DMA request completes,
a kernel panic will occur when those poison values are dereferenced.

This makes the DMA driver more robust in the face of buggy clients.

On versions of the Cortex-A9 prior to r3p0, an interrupted ICIALLUIS
operation may prevent the completion of a following broadcasted
operation if the second operation is received by a CPU before the
ICIALLUIS has completed, potentially leading to corrupted entries in
the cache or TLB.

This workaround sets a bit in the diagnostic register of the Cortex-A9,

885028e4ba ARM: 6741/1: errata: pl310 cache sync operation may be faulty
The effect of cache sync operation is to drain the store buffer and
wait for all internal buffers to be empty. In normal conditions, store
buffer is able to merge the normal memory writes within its 32-byte
data buffers.  Due to this erratum present in r3p0, the effect of cache
sync operation on the store buffer still remains when the operation
completes. This means that the store buffer is always asked to drain
and this prevents it from merging any further writes.

This can severely affect performance on the write traffic esp. on
Normal memory NC one.

The proposed workaround is to replace the normal offset of cache sync
operation(0x730) by another offset targeting an unmapped PL310
register 0x740.

Sometimes, due to high interrupt latency in the continuous mode
of DMA transfer, the half buffer complete interrupt is handled
after DMA has transferred the full buffer.  When this is detected,
stop DMA immediately and restart with the next buffer if the next
buffer is ready.

originally fixed by Victor(Weiguo) Pan <wpan@nvidia.com>

In place of using the simple spin_lock()/spi_unlock() in the
interrupt thread, using the spin_lock_irqsave() and
spin_unlock_irqrestore(). The lock is shared between the normal
process context and interrupt context.

originally fixed by Laxman Dewangan (ldewangan@nvidia.com)

The use of shadow registers caused memory corruption at physical
address 0 because the enable bit was not shadowed, and assuming it
needed to be set would enable an unconfigured dma block.  Most of the
register accesses don't need to know the previous state of the
registers, and the few places that do need to modify only a few bits
in the registers are the same ones that were sometimes incorrectly
setting the enable bit.  This patch convert tegra_dma_update_hardware
to set the entire register, and the other users to read-modify-write,
and drops the shadow registers completely.
