Device tree fixes for omaps for v5.0-rc cycle
This series of dts fixes for omap devices fixes several device specific
regressions:
- The onenand timings for n950/n9 have been wrong for a while since
we moved to dts based timings
- A typo for the cpcap pmic is now producing erors during boot as the
level should be 0 for unconfigurable triggering instead of 1
- Changes for ti-sysc for omap5 left uart3 with debug flags that should
not be set
- Fix a new dtc warning started showing up for omap3-gta04 grap_port
- With the generic MMC card detection code we need to fix the gpio
in dts for n900 and am335x-shc

git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into arm/fixes
This fixes a long standing typo in device-tree for DA850 in interrupt
number for timer. It did not affect us so far because we use non-DT
timer driver within mach-davinci. This was caught while migrating to
clocksource driver.

Second Round of Renesas ARM Based SoC Fixes for v5.0
Enable DMA for SCIF2 on R-Car M3-W (r8a7796) and M3-n (r8a77965), and
(RZ/G2M) r8a774a1 SoCs.
This is was omitted from patches enabling DMA for other SCIF devices on the
same SoCs due to missing documentation. However, it is regarded as a fix
as arguably those patches claim to add this feature.
Per-SoC patches are provided to ease backporting of this fix as the kernel
version to be fixed is different for each SoC.

i.MX fixes for 5.0:
- Fix spi_bus_bridge DTC warning by correcting '#address-cells' of
dspi3 node on vf610-bk4 board, as it's being used a SPI slave

PCI class.

show_ldttss() shifts desc.base2 by 24 bit, but base2 is 8 bits of a
bitfield in a u16.
Due to the really great idea of integer promotion in C99 base2 is promoted
to an int, because that's the standard defined behaviour when all values
which can be represented by base2 fit into an int.
Now if bit 7 is set in desc.base2 the result of the shift left by 24 makes
the resulting integer negative and the following conversion to unsigned
long legitmately sign extends first causing the upper bits 32 bits to be
set in the result.
Fix this by casting desc.base2 to unsigned long before the shift.

to long mode
In some old AMD KVM implementation, guest's EFER.LME bit is cleared by KVM
when the hypervsior detects that the guest sets CR0.PG to 0. This causes
the guest OS to reboot when it tries to return from 32-bit trampoline code
because the CPU is in incorrect state: CR4.PAE=1, CR0.PG=1, CS.L=1, but
EFER.LME=0. As a precaution, set EFER.LME=1 as part of long mode
activation procedure. This extra step won't cause any harm when Linux is
booted on a bare-metal machine.

The vma->vm_mm can become impossible to get before rdma_umap_close() is
called, in this case we must not try to get an mm that is already
undergoing process exit. In this case there is no need to wait for
anything as the VMA will be destroyed by another thread soon and is
already effectively 'unreachable' by userspace.

When an error happens, debugfs should return an error pointer value, not
NULL. This will prevent the totally theoretical error where a debugfs
call fails due to lack of memory, returning NULL, and that dentry value
is then passed to another debugfs call, which would end up succeeding,
creating a file at the root of the debugfs tree, but would then be
impossible to remove (because you can not remove the directory NULL).
So, to make everyone happy, always return errors, this makes the users
of debugfs much simpler (they do not have to ever check the return
value), and everyone can rest easy.

When generating vdso-o32.lds & vdso-n32.lds for use with programs
running as compat ABIs under 64b kernels, we previously haven't included
the compiler flags that are supposedly common to all ABIs - ie. those in
the ccflags-vdso variable.
This is problematic in cases where we need to provide the -m%-float flag
in order to ensure that we don't attempt to use a floating point ABI
that's incompatible with the target CPU & ABI. For example a toolchain
using current gcc trunk configured --with-fp-32=xx fails to build a
64r6el_defconfig kernel with the following error:
cc1: error: '-march=mips1' requires '-mfp32'
make[2]: *** [arch/mips/vdso/Makefile:135: arch/mips/vdso/vdso-o32.lds] Error 1
Include $(ccflags-vdso) for the compat VDSO .lds builds, just as it is
included for the native VDSO .lds & when compiling objects for the
compat VDSOs. This ensures we consistently provide the -msoft-float flag
amongst others, avoiding the problem by ensuring we're agnostic to the
toolchain defaults.

The MIPS VDSO build currently doesn't provide the -msoft-float flag to
the compiler as the kernel proper does. This results in an attempt to
use the compiler's default floating point configuration, which can be
problematic in cases where this is incompatible with the target CPU's
-march= flag. For example decstation_defconfig fails to build using
toolchains in which gcc was configured --with-fp-32=xx with the
following error:
LDS arch/mips/vdso/vdso.lds
cc1: error: '-march=r3000' requires '-mfp32'
make[2]: *** [scripts/Makefile.build:379: arch/mips/vdso/vdso.lds] Error 1
The kernel proper avoids this error because we build with the
-msoft-float compiler flag, rather than using the compiler's default.
Pass this flag through to the VDSO build so that it too becomes agnostic
to the toolchain's floating point configuration.
Note that this is filtered out from KBUILD_CFLAGS rather than simply
always using -msoft-float such that if we switch the kernel to use
-mno-float in the future the VDSO will automatically inherit the change.
The VDSO doesn't actually include any floating point code, and its
.MIPS.abiflags section is already manually generated to specify that
it's compatible with any floating point ABI. As such this change should
have no effect on the resulting VDSO, apart from fixing the build

Add multiple people as maintainers for XDP, sorted alphabetically.
XDP is also tied to driver level support and code, but we cannot add all
drivers to the list. Instead K: and N: match on 'xdp' in hope to catch some
of those changes in drivers.

The skb should be freed by dev_consume_skb_any() in b44_start_xmit()
when bounce_skb is used. The skb is be replaced by bounce_skb, so the
original skb should be consumed(not drop).
dev_consume_skb_irq() should be called in b44_tx() when skb xmit
done. It makes drop profiles(dropwatch, perf) more friendly.

struct snd_soc_dapm_route has been modified to be a dynamic
object so that it can be used to save driver specific
data while parsing topology and clean up
driver-specific data during driver unloading.
This patch makes the following changes to accomplish the above:
1. Set the dobj member of snd_soc_dapm_route during the
SOC_TPLG_PASS_GRAPH pass of topology parsing.
2. Add the remove_route() routine that will be called while
removing all dynamic objects from the component driver.

Add a new dobj type SND_SOC_DOBJ_GRAPH for dapm routes
and add snd_soc_dobj member to struct snd_soc_dapm_route.
This enables device drivers to save driver specific
data pertaining to dapm routes and also be able
to clean up the data when the driver module is unloaded.
Also, reorder the snd_soc_dobj_type types to align with
matching topology header types.

The interrupt handler contains a workaround for RX hang applicable
to Zynq and AT91RM9200 only. Subsequent versions do not need this
workaround. This workaround unnecessarily resets RX whenever RX used
bit read is observed, which can be often under heavy traffic. There
is no other action performed on RX UBR interrupt. Hence introduce a
CAPS mask; enable this interrupt and workaround only on affected
versions.

Currently the registration and free of beep input device was done
manually from the register and the disconnect callbacks of the
assigned codec object. This seems working in most cases, but this may
be a cause of some races at probe. Moreover, due to these manual
calls, the total code became unnecessarily lengthy.
This patch rewrites the beep registration code to follow the standard
sound device object style. This allows us reducing the code, in
addition to avoiding the nested device registration calls.

The init sequence for ALC294 headphone stuff is needed not only for
the boot up time but also for the resume from hibernation, where the
device is switched from the boot kernel without sound driver to the
suspended image. Since we record the PM event in the device
power_state field, we can now recognize the call pattern and apply the
sequence conditionally.

Currently we deal with single codec and suspend codec callbacks for
all S3, S4 and runtime PM handling. But it turned out that we want
distinguish the call patterns sometimes, e.g. for applying some init
sequence only at probing and restoring from hibernate.
This patch slightly modifies the common PM callbacks for HD-audio
codec and stores the currently processed PM event in power_state of
the codec's device.power field, which is currently unused. The codec
callback can take a look at this event value and judges which purpose
it's being called.

Add missing break statement in order to prevent the code from falling
through to the default case.
The resoning for this is that pclk_vol_table is an automatic variable.
So, it makes no sense to update it just before falling through to the
default case and return -EINVAL.
This bug was found thanks to the ongoing efforts to enabling
-Wimplicit-fallthrough.
