This is the System MMU driver and IOMMU API implementation for
EXYNOS SoC platforms. EXYNOS platforms has more than 10 System
MMUs dedicated for each multimedia accelerators.
The System MMU driver is already in arc/arm/plat-s5p but it is
moved to drivers/iommu due to Ohad Ben-Cohen gathered IOMMU
drivers there.
Any device driver in EXYNOS platforms that needs to control its
System MMU must call platform_set_sysmmu() to inform System MMU
driver who will control it. platform_set_sysmmu() is defined in
<mach/sysmmu.h>

The omap/dt branch adds a few instances of mmc device nodes that
need to get changed to use the common bindings. Pull that into
a new branch so we can apply the patch in a single run.

Tegra AHB Bus conforms to the AMBA Specification (Rev 2.0) Advanced
High-performance Bus (AHB) architecture.
The AHB Arbiter controls AHB bus master arbitration. This effectively
forms a second level of arbitration for access to the memory
controller through the AHB Slave Memory device. The AHB pre-fetch
logic can be configured to enhance performance for devices doing
sequential access. Each AHB master is assigned to either the high or
low priority bin. Both Tegra20/30 have this AHB bus.
Some of configuration params could be passed from DT too if needed.

Handling System MMUs with an identifier is not flexible to manage
System MMU platform devices because of the following reasons:
1. A device driver which needs to handle System MMU must know the ID.
2. A System MMU may not present in some implementations of Exynos family.
3. Handling System MMU with IOMMU API does not require an ID.
This patch is the result of removing ID of System MMUs.
Instead, a device driver that needs to handle its System MMU must
use IOMMU API while its descriptor of platform device is given.
This patch also includes the following enhancements:
- A System MMU device becomes a child if its power domain device.
- clkdev

This patch removes System MMU device driver from arm/plat-s5p tree
for transition to implement IOMMU driver.
Although controlling System MMU in this removing driver
is similar to the new IOMMU driver in the following patch,
the new one is almost rewrite of this driver and there is no
benefit to moving the driver file from arch/arm/ to drivers/iommu.

The ISR does quiete a lot of hw access which could be avoided. First it
checks for a pending interrupt by reading alteast one register. Then it
checks for the "activated" slots by reading another register. This is
more or a less a must.
Now, once it found an active slot it does the same two reads again.
After that it "knows" that there must be a pending transfer however it
cross checks with the other register. There are 32 bit in an interger
which are polled instead of considering only the set bits and ignoring
those which are zero. This performs atleast 32 reads which could be
avoided. In case of a first match it does another read.
This patch reorganizes the access by re-using the register which have
been read and then uses ffs() to find the matching slot instead looping
over it. By doing this we get rid of the last (32 + 2 + hits) reads.
It is possible however that by really busy bank0 we never get to handle
bank1. If this is a problem, we could try to handle bank1 after we are
done with bank0 to check if there are any outstanding transfers.
To put some numbers on this, this is from spi transfer via spidev. The
first column is the number of total transfers, the time stamp is taken
before and after the ioctl():
|10000, min: 542us avg: 591us
|20000, min: 542us avg: 592us
|30000, min: 542us avg: 592us
|40000, min: 542us avg: 585us
|50000, min: 542us avg: 593us
The same test case with the patch applied
|10000, min: 444us avg: 493us
|20000, min: 444us avg: 491us
|30000, min: 444us avg: 489us
|40000, min: 444us avg: 491us
|50000, min: 444us avg: 492us
that is almost 100us that just went away.

Apart from the necessity to do this change for multi-platform kernels
the previous logic depended on the zImage decompressor to write the
physical and virtual address to a magic memory location.
If the decompressor is unused or not correctly configured for the
current machid, the addruart macro was an infinite loop. Moreover
debugging the early zImage code was not possible either.

It seems that there was an error with the active_low = 1 for the
LED, since it should be set to 0 (meaning that active is high,
since 0 is false, hence the confusion.
The wiki article about it confuses it, since it contradicts itself,
regarding what turns on the LED.
I have tested 3.4-rc2 on my net5501 with this patch, and it makes the LED
behave correctly, where "none" turns it off, and "default-on" turns it on,
when echoed onto the trigger "file" in /sys/class/leds.

[ hpa: putting this in urgent because of the sheer harmlessness of the patch:
it quiets a build warning but does not change any generated code. ]

<asm-generic/statfs.h> is exported to userspace, so using
BITS_PER_LONG is invalid. We need to use __BITS_PER_LONG instead.
This is kernel bugzilla 43165.

BIOS will switch off the corresponding feature flag on family
15h models 10h-1fh non-desktop CPUs.
The topology extension CPUID leafs are required to detect which
cores belong to the same compute unit. (thread siblings mask is
set accordingly and also correct information about L1i and L2
cache sharing depends on this).
W/o this patch we wouldn't see which cores belong to the same
compute unit and also cache sharing information for L1i and L2
would be incorrect on such systems.

Pull btrfs fixes from Chris Mason:
"The big ones here are a memory leak we introduced in rc1, and a
scheduling while atomic if the transid on disk doesn't match the
transid we expected. This happens for corrupt blocks, or out of date
disks.
It also fixes up the ioctl definition for our ioctl to resolve logical
inode numbers. The __u32 was a merging error and doesn't match what
we ship in the progs."

verify_parent_transid needs to lock the extent range to make
sure no IO is underway, and so it can safely clear the
uptodate bits if our checks fail.
But, a few callers are using it with spinlocks held. Most
of the time, the generation numbers are going to match, and
we don't want to switch to a blocking lock just for the error
case. This adds an atomic flag to verify_parent_transid,
and changes it to return EAGAIN if it needs to block to
properly verifiy things.

Fix that when scrub tries to repair an I/O or checksum error and one of
the devices containing the mirror is missing, it crashes in bio_add_page

If we happen to alloc a extent buffer and then alloc a page and notice that
page is already attached to an extent buffer, we will only unlock it and
free our existing eb. Any pages currently attached to that eb will be
properly freed, but we don't do the page_cache_release() on the page where
we noticed the other extent buffer which can cause us to leak pages and I
hope cause the weird issues we've been seeing in this area. Thanks,
