8bb957d255 net/mlx5: E-Switch, Introduce flow counter affinity
This dictates the device affinity for eswitch flow counters, set by the FW
according to the HW device capabilities.

Under "source eswitch" affinity, the counter should be allocated on the
device related to the source vport in the match. This covers both non
merged e-switch mode as well as old FW that does not advertise this cap.

Under "flow eswitch" affinity, the counter should be allocated on the
device where the eswitch rule is set.

2bc39970e9 x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID
With every new Hyper-V Enlightenment we implement we're forced to add a
KVM_CAP_HYPERV_* capability. While this approach works it is fairly
inconvenient: the majority of the enlightenments we do have corresponding
CPUID feature bit(s) and userspace has to know this anyways to be able to
expose the feature to the guest.

Add KVM_GET_SUPPORTED_HV_CPUID ioctl (backed by KVM_CAP_HYPERV_CPUID, "one
cap to rule them all!") returning all Hyper-V CPUID feature leaves.

Using the existing KVM_GET_SUPPORTED_CPUID doesn't seem to be possible:
Hyper-V CPUID feature leaves intersect with KVM's (e.g. 0x40000000,
0x40000001) and we would probably confuse userspace in case we decide to
return these twice.

KVM_CAP_HYPERV_CPUID's number is interim: we're intended to drop
KVM_CAP_HYPERV_STIMER_DIRECT and use its number instead.

71391bdd2e include/linux/compiler_types.h: don't pollute userspace with macro definitions
Macros 'inline' and '__gnu_inline' used to be defined in compiler-gcc.h,
which was (and is) included entirely in (__KERNEL__ && !__ASSEMBLY__).
Commit 815f0ddb34 ("include/linux/compiler*.h: make compiler-*.h mutually
exclusive") had those macros exposed to userspace, unintentionally.

Then commit a3f8a30f3f ("Compiler Attributes: use feature checks
instead of version checks") moved '__gnu_inline' back into
(__KERNEL__ && !__ASSEMBLY__) and 'inline' was left behind. Since 'inline'
depends on '__gnu_inline', compiling error showing "unknown type name
‘__gnu_inline’" will pop up, if userspace somehow includes
<linux/compiler.h>.

Other macros like __must_check, notrace, etc. are in a similar situation.
So just move all these macros back into (__KERNEL__ && !__ASSEMBLY__).

Note:
  1. This patch only affects what userspace sees.
  2. __must_check (when !CONFIG_ENABLE_MUST_CHECK) and noinline_for_stack
     were once defined in __KERNEL__ only, but we believe that they can
     be put into !__ASSEMBLY__ too.

c5510b8daf gpiolib: Fix return value of gpio_to_desc() stub if !GPIOLIB
If CONFIG_GPOILIB is not set, the stub of gpio_to_desc() should return
the same type of error as regular version: NULL.  All the callers
compare the return value of gpio_to_desc() against NULL, so returned
ERR_PTR would be treated as non-error case leading to dereferencing of
error value.

2a31b9db15 kvm: introduce manual dirty log reprotect
There are two problems with KVM_GET_DIRTY_LOG.  First, and less important,
it can take kvm->mmu_lock for an extended period of time.  Second, its user
can actually see many false positives in some cases.  The latter is due
to a benign race like this:

  1. KVM_GET_DIRTY_LOG returns a set of dirty pages and write protects
     them.
  2. The guest modifies the pages, causing them to be marked ditry.
  3. Userspace actually copies the pages.
  4. KVM_GET_DIRTY_LOG returns those pages as dirty again, even though
     they were not written to since (3).

This is especially a problem for large guests, where the time between
(1) and (3) can be substantial.  This patch introduces a new
capability which, when enabled, makes KVM_GET_DIRTY_LOG not
write-protect the pages it returns.  Instead, userspace has to
explicitly clear the dirty log bits just before using the content
of the page.  The new KVM_CLEAR_DIRTY_LOG ioctl can also operate on a
64-page granularity rather than requiring to sync a full memslot;
this way, the mmu_lock is taken for small amounts of time, and
only a small amount of time will pass between write protection
of pages and the sending of their content.

18edf49c45 PM / Domains: Propagate performance state updates
Currently a genpd only handles the performance state requirements from
the devices under its control. This commit extends that to also handle
the performance state requirement(s) put on the master genpd by its
sub-domains. There is a separate value required for each master that
the genpd has and so a new field is added to the struct gpd_link
(link->performance_state), which represents the link between a genpd and
its master. The struct gpd_link also got another field
prev_performance_state, which is used by genpd core as a temporary
variable during transitions.

On a call to dev_pm_genpd_set_performance_state(), the genpd core first
updates the performance state of the masters of the device's genpd and
then updates the performance state of the genpd. The masters do the same
and propagate performance state updates to their masters before updating
their own. The performance state transition from genpd to its master is
done with the help of dev_pm_opp_xlate_performance_state(), which looks
at the OPP tables of both the domains to translate the state.

1067ae3e42 PM / Domains: Save OPP table pointer in genpd
dev_pm_genpd_set_performance_state() will be required to call
dev_pm_opp_xlate_performance_state() going forward to translate from
performance state of a sub-domain to performance state of its master.
And dev_pm_opp_xlate_performance_state() needs pointers to the OPP
tables of both genpd and its master.

Lets fetch and save them while the OPP tables are added. Fetching the
OPP tables should never fail as we just added the OPP tables and so add
a WARN_ON() for such a bug instead of full error paths.

2feb5a896c OPP: Don't return 0 on error from of_get_required_opp_performance_state()
of_get_required_opp_performance_state() returns 0 on errors currently
and a positive performance state otherwise. Since 0 is a valid
performance state (representing off), it would be better if this routine
returns negative values on error.

That will also make it behave similar to
dev_pm_opp_xlate_performance_state(), which also returns performance
states and returns negative values on error. Change the return type of
the function to "int" in order to return negative values.

This doesn't have any users for now and so no other part of the kernel
will be impacted with this change.

c8a59103e2 OPP: Add dev_pm_opp_xlate_performance_state() helper
dev_pm_genpd_set_performance_state() needs to handle performance state
propagation going forward. Currently this routine only gets the required
performance state of the device's genpd as an argument, but it doesn't
know how to translate that to master genpd(s) of the device's genpd.

Introduce a new helper dev_pm_opp_xlate_performance_state() which will
be used to translate from performance state of a device (or genpd
sub-domain) to another device (or master genpd).

Normally the src_table (of genpd sub-domain) will have the
"required_opps" property set to point to one of the OPPs in the
dst_table (of master genpd), but in some cases the genpd and its master
have one to one mapping of performance states and so none of them have
the "required-opps" property set. Return the performance state of the
src_table as it is in such cases.

model to control the clock gates for the peripherals. An LPCG module
is used to locally gate the clocks for the associated peripheral.

Note:
This level of clock gating is provided after the clocks are generated
by the SCU resources and clock controls. Thus even if the clock is
enabled by these control bits, it might still not be running based
on the base resource.

Saeed Mahameed says:

====================
This series introduces some fixes to the mlx5 core and mlx5e netdevice
driver.

=======
Conflict with net-next: When merged with net-next this series will
cause a moderate conflict:

1) in drivers/net/ethernet/mellanox/mlx5/core/en_tc.c (2 hunks)
Take hunks from net only and just replace *attr->mirror_count to *attr->split_count
1.1) there is one more instance of slow_attr->mirror_count to be replaced
with slow_attr->split_count, it doesn't appear in the conflict, it will
cause a compilation error if left out.
2) in mlx5_ifc.h, take hunks only from net.

Example for the merge resolution can be found at:
https://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git/commit/?h=merge/mlx5-fixes&id=48830adf29804d85d77ed8a251d625db0eb5b8a8
branch merge/mlx5-fixes of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux
(I simply merged this pull request tag into net-next and resolved the conflict)

I don't know if it's ok with you, but to save your time, you can just:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux merge/mlx5-fixes
Into net-next, before your next net merge, and you will have a clean
merge of net into net-next (at least for mlx5 files).

1570415f08 net: dev: Add NETDEV_PRE_CHANGEADDR
The NETDEV_CHANGEADDR notification is emitted after a device address
changes. Extending this message to allow vetoing is certainly possible,
but several other notification types have instead adopted a simple
two-stage approach: first a "pre" notification is sent to make sure all
interested parties are OK with a change that's about to be done. Then
the change is done, and afterwards a "post" notification is sent.

This dual approach is easier to use: when the change is vetoed, nothing
has changed yet, and it's therefore unnecessary to roll anything back.
Therefore adopt it for NETDEV_CHANGEADDR as well.

To that end, add NETDEV_PRE_CHANGEADDR and an info structure to go along
with it.

b5f06893c4 drm: Rename crtc_idr as object_idr to KMS cleanups
This patch solves this TODO task:
 drm_mode_config.crtc_idr is misnamed, since it contains all KMS object.
 Should be renamed to drm_mode_config.object_idr.

55897af630 dma-direct: merge swiotlb_dma_ops into the dma_direct code
While the dma-direct code is (relatively) clean and simple we actually
have to use the swiotlb ops for the mapping on many architectures due
to devices with addressing limits.  Instead of keeping two
implementations around this commit allows the dma-direct
implementation to call the swiotlb bounce buffering functions and
thus share the guts of the mapping implementation.  This also
simplified the dma-mapping setup on a few architectures where we
don't have to differenciate which implementation to use.

68c608345c swiotlb: remove dma_mark_clean
Instead of providing a special dma_mark_clean hook just for ia64, switch
ia64 to use the normal arch_sync_dma_for_cpu hooks instead.

This means that we now also set the PG_arch_1 bit for pages in the
swiotlb buffer, which isn't stricly needed as we will never execute code
out of the swiotlb buffer, but otherwise harmless.

90ac706e98 dma-mapping: factor out dummy DMA ops
The dummy DMA ops are currently used by arm64 for any device which has
an invalid ACPI description and is thus barred from using DMA due to not
knowing whether is is cache-coherent or not. Factor these out into
general dma-mapping code so that they can be referenced from other
common code paths. In the process, we can prune all the optional
callbacks which just do the same thing as the default behaviour, and
fill in .map_resource for completeness.

d907be2b5b xen/pvh: Add memory map pointer to hvm_start_info struct
The start info structure that is defined as part of the x86/HVM direct boot
ABI and used for starting Xen PVH guests would be more versatile if it also
included a way to pass information about the memory map to the guest. This
would allow KVM guests to share the same entry point.

8cee3974b3 xen/pvh: Move Xen specific PVH VM initialization out of common file
We need to refactor PVH entry code so that support for other hypervisors
like Qemu/KVM can be added more easily.

This patch moves the small block of code used for initializing Xen PVH
virtual machines into the Xen specific file. This initialization is not
going to be needed for Qemu/KVM guests. Moving it out of the common file
is going to allow us to compile kernels in the future without CONFIG_XEN
that are still capable of being booted as a Qemu/KVM guest via the PVH
entry point.
