The functions snd_emu10k1_proc_spdif_read and snd_emu1010_fpga_read
acquire the emu_lock before accessing the FPGA. The function used
to access the FPGA (snd_emu1010_fpga_read) also tries to take
the emu_lock which causes a deadlock.
Remove the outer locking in the proc-functions (guarding only the
already safe fpga read) to prevent this deadlock.
[removed superfluous flags variables too -- tiwai]

This patch updates the binding information to reflect the
extra dt options which are now supported by the sdhci-st.c
driver which enable support for stih407 family silicon.
STiH410 SoC and later support UHS modes for eMMC, so the
driver now makes use of these common bindings. Examples
are provided for both eMMC (which has additional bindings)
and also sd slot for STiH407.

Some additional quirks need to be enabled now we support UHS
modes. This avoids some spurious warnings like
"Got data interrupt 0x00000002 even though no data operation was in progress"
Testing on stih410-b2120 board achieves the following speeds
with HS200 eMMC card.
max-frequency = 200Mhz
/dev/mmcblk0p1:
Timing buffered disk reads: 270 MB in 3.02 seconds = 89.54 MB/sec
max-frequency = 100Mhz
root@debian-armhf:~# hdparm -t /dev/mmcblk0p1
/dev/mmcblk0p1:
Timing buffered disk reads: 210 MB in 3.00 seconds = 70.00 MB/sec
max-frequency = 50Mhz
root@debian-armhf:~# hdparm -t /dev/mmcblk0p1
/dev/mmcblk0p1:
Timing buffered disk reads: 118 MB in 3.00 seconds = 39.28 MB/sec
This is better than the 3.10 kernel which achieves 77.59 MB/sec
at 200Mhz clock (same board/soc/eMMC).

To allow UHS modes to work properly we need to provide the st specific
set_uhs_signaling callback function. This function differs from the
generic sdhci_set_uhs_signaling callback in that we need to configure
the correct delay depending on the UHS mode, and also set the V18_EN
bit.

Due to the tight timing constraints in some UHS modes, it is required to have
some delay management in the design. Two types of delay management are supported
in the HW: -
1) Static delay management
2) Dynamic delay management
NB: The delay management is only there when eMMC interface is selected.
1: Static delay management: is used to provide PVT dependent static delay on the
clock/data lines to manage setup/hold requirements of the interface. The maximum
delay possible is 3.25ns. These delays are PVT dependent, and thus delay values
applied are not accurate and vary across provcess voltage and temperature range.
Due to this these delays must not be used on the very time critical paths.
2. Dynamic delay locked loop (DLL): is used to provide dynamic delay management.
The advantage of DLL is that it provides accurate & PVT indepedent delay.
The DLL is used to provide delay on the loopback clock on "Read Path" to capture
read data reliably. On TX path the clock on which output data is transmitted is
delayed, resulting in delay of TX data.

STiH407 family SoC's can have a reset signal for the controller which needs to
be managed. Also the eMMC controller has some additional 'top' memory mapped
registers which are used to manage the dynamic and static delay required for
UHS modes. This patch adds support for creating the mapping, which will be used
by subsequent patches.

smp_ops->probe() is currently supposed to return the number of cpus in
the system.
The last actual usage of the value was removed in May 2007 in e147ec8f1808
"[POWERPC] Simplify smp_space_timers". We still passed the value around
until June 2010 when even that was finally removed in c1aa687d499a
"powerpc: Clean up obsolete code relating to decrementer and timebase".
So drop that requirement, probe() now returns void, and update all
implementations.

The conversion from __get_cpu_var() to this_cpu_ptr() in iic_setup_cpu()
is wrong. It causes an oops at boot.
We need the per-cpu address of struct cpu_iic, not cpu_iic.regs->prio.
Sparse noticed this, because we pass a non-iomem pointer to out_be64(),
but we obviously don't check the sparse results often enough.

We get way too many bug reports that say "the kernel is hung in
prom_init", which stems from the fact that the last piece of output
people see is "returning from prom_init".
The kernel is almost never hung in prom_init(), it's just that it's
crashed somewhere after prom_init() but prior to the console coming up.
The existing message should give a clue to that, ie. "returning from"
indicates that prom_init() has finished, but it doesn't seem to work.
Let's try something different.
This prints:
Quiescing Open Firmware ...
Booting Linux via __start() ...
Which hopefully makes it clear that prom_init() is not the problem, and
although __start() probably isn't either, it's at least the right place
to begin looking.

We have a powerpc specific global called mem_init_done which is "set on
boot once kmalloc can be called".
But that's not *quite* true. We set it at the bottom of mem_init(), and
rely on the fact that mm_init() calls kmem_cache_init() immediately
after that, and nothing is running in parallel.
So replace it with the generic and 100% correct slab_is_available().

Both ARM946 and ARM940 setup functions were corrupting r1 and r2,
which is not permissible - these are used to carry the machine ID
and boot data into the kernel, and must be preserved.
The code responsible for this was the same in both files: they were
using the registers to generate a protection region register value.
Fix this by turning this process into a macro, and using that macro
in both these files with an alternative register allocation. r0,
r3 and r7 can be used for temporary values here.

This change makes it so that the HW_VLAN_CTAG_FILTER bit is not falsely
advertised as being a feature that can be toggled on ixgbe parts. The
driver was setting the bit in features and letting it be inherited by
hw_features, however the driver was actually ignoring the value of the bit
and just assuming it was always set. As a result VLAN filtering was always
enabled which is a requirement for SR-IOV, VMDq, DCB, FCoE, and possibly
other features within the adapters.

in v3.14-rc1 RAID0 has performed incorrect calculations
