When decoding the perf_regs mask in perf_output_sample_regs(),
we loop through the mask using find_first_bit and find_next_bit functions.
While the exisiting code works fine in most of the case, the logic
is broken for big-endian 32-bit kernels.
When reading a u64 mask using (u32 *)(&val)[0], find_*_bit() assumes
that it gets the lower 32 bits of u64, but instead it gets the upper
32 bits - which is wrong.
The fix is to swap the words of the u64 to handle this case.
This is _not_ a regular endianness swap.

As we moved the vdev handling to the main boot/shutdown code path we can
further simplify the resource table handling by moving the parsing spet
to boot as well. The lifespan of the resource table is changed to live
from rproc_boot() to rproc_shutdown().

Now as all commands use mlx5 ifc interface, instead of doing two calls

Prior to this patch we assumed that modify QP commands have the
same layout.
In ConnectX-4 for each QP transition there is a specific command
and their layout can vary.
e.g: 2err/2rst commands don't have QP context in their layout and before
this patch we posted the QP context in those commands.
Fortunately the FW only checks the suffix of the commands and executes
them, while ignoring all invalid data sent after the valid command
layout.
This patch removes mlx5_modify_qp_mbox_in and changes
mlx5_core_qp_modify to receive the required transition and QP context
with opt_param_mask if needed. This way the caller is not required to
provide the command inbox layout and it will be generated automatically.
mlx5_core_qp_modify will generate the command inbox/outbox layouts
according to the requested transition and will fill the requested
parameters.

It is useful to know the reason why cpufreq_update_util() has just
been called and that can be passed as flags to cpufreq_update_util()
and to the ->func() callback in struct update_util_data. However,
doing that in addition to passing the util and max arguments they
already take would be clumsy, so avoid it.
Instead, use the observation that the schedutil governor is part
of the scheduler proper, so it can access scheduler data directly.
This allows the util and max arguments of cpufreq_update_util()
and the ->func() callback in struct update_util_data to be replaced
with a flags one, but schedutil has to be modified to follow.
Thus make the schedutil governor obtain the CFS utilization
information from the scheduler and use the "RT" and "DL" flags
instead of the special utilization value of ULONG_MAX to track
updates from the RT and DL sched classes. Make it non-modular
too to avoid having to export scheduler variables to modules at
large.
Next, update all of the other users of cpufreq_update_util()
and the ->func() callback in struct update_util_data accordingly.

Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of
certain interrupt types, pass positive flags like PCI_IRQ_LEGACY,
PCI_IRQ_MSI, etc., to specify the acceptable interrupt types.
This is based on a number of pending driver conversions that just happend
to be a whole more obvious to read this way, and given that we have no
users in the tree yet it can still easily be done.
I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting
all interrupt types very simple.

Currently bcma-hcd driver handles 3 different bcma cores:
1) BCMA_CORE_USB20_HOST (0x819)
2) BCMA_CORE_NS_USB20 (0x504)
3) BCMA_CORE_NS_USB30 (0x505)
The first one was introduced years ago and so far was used on MIPS
devices only. All Northstar (ARM) devices were using other two cores
which allowed easy implementation of separated initialization paths.
It seems however Broadcom decided to reuse this old USB 2.0 controller
on some recently introduced cheaper Northstar BCM53573 SoCs. I noticed
this on Tenda AC9 (based on BCM47189B0 belonging to BCM53573 family).
There is no difference in this old controller core identification
between MIPS and ARM devices: they share the same id and revision. We
need different controller initialization procedure however.
To handle this add a check for architecture and implement required
initialization for ARM case.

The idea for type_check in dev_get_nest_level() was to count the number
of nested devices of the same type (currently, only macvlan or vlan
devices).
This prevented the false positive lockdep warning on configurations such
as:
eth0 <--- macvlan0 <--- vlan0 <--- macvlan1
However, this doesn't prevent a warning on a configuration such as:
eth0 <--- macvlan0 <--- vlan0
eth1 <--- vlan1 <--- macvlan1
In this case, all the locks end up with a nesting subclass of 1, so
lockdep thinks that there is still a deadlock:
- in the first case we have (macvlan_netdev_addr_lock_key, 1) and then
take (vlan_netdev_xmit_lock_key, 1)
- in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then
take (macvlan_netdev_addr_lock_key, 1)
By removing the linktype check in dev_get_nest_level() and always
incrementing the nesting depth, lockdep considers this configuration
valid.

Commit 0431b9065f28ecf6c320fefebe0241620049984f ("staging/android: bring
struct sync_pt back") removed child_list and active_list from struct fence,
but left it in kernel doc. Delete them.

KVM devices were manipulating list data structures without any form of
synchronization, and some implementations of the create operations also
suffered from a lack of synchronization.
Now when we've split the xics create operation into create and init, we
can hold the kvm->lock mutex while calling the create operation and when
manipulating the devices list.
The error path in the generic code gets slightly ugly because we have to
take the mutex again and delete the device from the list, but holding
the mutex during anon_inode_getfd or releasing/locking the mutex in the
common non-error path seemed wrong.

As we are about to hold the kvm->lock during the create operation on KVM
devices, we should move the call to xics_debugfs_init into its own
function, since holding a mutex over extended amounts of time might not
be a good idea.
Introduce an init operation on the kvm_device_ops struct which cannot
fail and call this, if configured, after the device has been created.

Create a new header file for TI DA8XX SoC CFGCHIPx registers.
This will be used by a number of planned drivers including a new USB
PHY driver and common clock framework drivers.
The same defines *will* be removed from the platform_data header,
once all the users start using the new syscon device header.
This also fixes the following compiler error caused due to
a dependent patch not merged.
drivers/phy/phy-da8xx-usb.c:19:37:
fatal error: linux/mfd/da8xx-cfgchip.h: No such file or directory
#include <linux/mfd/da8xx-cfgchip.h>

Due to the (indirect) nesting of min(..., min(...)), sparse will
show a variable shadowing warning whenever bvec.h is included.
Avoid that by assigning the inner min() to a temporary variable first.

The Nomadik variant has a few special quirks that need to be respected
to make the driver work:
- The block need to be clocked during writing of the TIMn registers
or the bus will stall.
- Special bits in the control register select how many of the output
display lines get activated.
- Special bits in the control register select how to manage the
different 565 and 5551 modes.
- There is a packed 24bit graphics mode, i.e 888 pixels can be stored
in memory is three consecutive bytes, not evenly aligned to a 32bit
word.
This patch uses the vendor data pointer from the AMBA matching mechanism
to track the quirks for this variant, and adds two hooks that variants
can use to initialize boards and panels during start-up. These will
later be used to adopt a Nomadik board profile.

There are CLCDs connected with the pads in BGR rather than RGB
order. It really doesn't matter since the CLCD has a flag and
a bit to switch the position of the RGB and BGR components.
This is needed to put something logical into the
arm,pl11x,tft-r0g0b0-pads property of the device tree on the
Nomadik which will then be <16 8 0>.
