Merge "ARM: tegra: core code changes for 3.17" from Thierry Reding:
Some of the code that's currently called from the Tegra machine setup
code is moved to regular initcalls. To catch dependency violations, the
various code paths now WARN if they're called to early. Not all of the
potential candidates are converted yet, but those that were have been
verified to work across all supported Tegra generations.
A new function, soc_is_tegra(), is also provided to make sure that the
initcalls can abort early if they aren't run on Tegra, which can happen
for multi-platform builds.
Finally this also moves out the PMC driver to drivers/soc/tegra so that
it can be shared with 64-bit ARM.
This is based on the for-3.17/fuse-move branch. The split is somewhat
arbitrary but allows the dependents of the for-3.17/fuse-move to pull
in as little code as necessary.

Merge "ARM: tegra: move fuse code out of arch/arm" from Thierry Reding:
This branch moves code related to the Tegra fuses out of arch/arm and
into a centralized location which could be shared with ARM64. It also
adds support for reading the fuse data through sysfs.
Included is also some preparatory work that moves Tegra-related header
files from include/linux to include/soc/tegra as suggested by Arnd.
Furthermore the Tegra chip ID is now retrieved using a function rather
than a variable so that sanity checks can be done. This is convenient
in subsequent patches that will move some of the code that's currently
called from Tegra machine setup into regular initcalls so that it can
be reused on 64-bit ARM. The sanity checks help with verifying that no
code tries to obtain the Tegra chip ID before the underlying driver is
properly initialized.

This commit converts the PMC support code to a platform driver. Because
the boot process needs to call into this driver very early, also set up
a minimal environment via an early initcall.

Rather than rely on explicit initialization order called from SoC setup
code, use a plain initcall and rely on initcall ordering to take care of
dependencies.
This driver exposes some functionality (querying the chip ID) needed at
very early stages of the boot process. An early initcall is good enough
provided that some of the dependencies are deferred to later stages. To
make sure any abuses are easily caught, output a warning message if the
chip ID is queried while it can't be read yet.

Subsequent patches will move some of the initialization code from SoC
setup code to regular initcalls. To prevent breakage on other SoCs in
multi-platform builds, these initcalls need to check that they indeed
run on Tegra.

The Tegra fuse header's dummy functions for the case where Tegra20 is
disabled are inconsistent with the correct prototypes, and have some
syntax errors. Fix these. While at it, fix the indentation level of

The Tegra20 fuse driver is the only user of tegra_apb_readl_using_dma().
Therefore we can simply the code by incorporating the APB DMA handling into
the driver directly. tegra_apb_writel_using_dma() is dropped because there
are no users.

replaces functionality previously provided in arch/arm/mach-tegra, which
is removed in this patch.
While at it, move the only user of the global tegra_revision variable

For Haswell and Broadwell, if the display power well has been disabled,
the display audio controller divider values EM4 M VALUE and EM5 N VALUE
will have been lost. The CDCLK frequency is required for reprogramming them
to generate 24MHz HD-A link BCLK. So provide a private interface for the
audio driver to query CDCLK.
This is a stopgap solution until a more generic interface between audio
and display drivers has been implemented.

Alexander reported mkswap on /dev/zram0 is failed if other process is
opening the block device file.
Step is as follows,
0. Reset the unused zram device.
1. Use a program that opens /dev/zram0 with O_RDWR and sleeps
until killed.
2. While that program sleeps, echo the correct value to
/sys/block/zram0/disksize.
3. Verify (e.g. in /proc/partitions) that the disk size is applied
correctly. It is.
4. While that program still sleeps, attempt to mkswap /dev/zram0.
This fails: mkswap: error: swap area needs to be at least 40 KiB
When I investigated, the size get by ioctl(fd, BLKGETSIZE64, xxx) on
mkswap to get a size of blockdev was zero although zram0 has right size by
2.
The reason is zram didn't revalidate disk after changing capacity so that
size of blockdev's inode is not uptodate until all of file is close.
This patch should fix the BUG.

When we write to a degraded array which has a bitmap, we
make sure the relevant bit in the bitmap remains set when
the write completes (so a 're-add' can quickly rebuilt a
temporarily-missing device).
If, immediately after such a write starts, we incorporate a spare,
commence recovery, and skip over the region where the write is
happening (because the 'needs recovery' flag isn't set yet),
then that write will not get to the new device.
Once the recovery finishes the new device will be trusted, but will
have incorrect data, leading to possible corruption.
We cannot set the 'needs recovery' flag when we start the write as we
do not know easily if the write will be "degraded" or not. That
depends on details of the particular raid level and particular write
request.
This patch fixes a corruption issue of long standing and so it
suitable for any -stable kernel. It applied correctly to 3.0 at
least and will minor editing to earlier kernels.

We need to delete un-finished td from current request's td list
at ep_dequeue API, otherwise, this non-user td will be remained
at td list before this request is freed. So if we do ep_queue->

the second ep_queue comes, we search td list for this request,
the first td (added by the first ep_queue) will be handled, and
its status is still active, so we will consider the this transfer

test item for USBCV2 MSC test, the host has never received ACK for
the IN token for CSW due to peripheral considers it does not get this
