[ Upstream commit c29de84149aba5f74e87b6491c13ac7203c12f55 ]

The PCI port driver saves the PCI state after initializing the device with
the applicable service devices.  This was, however, before the service
drivers were even registered because PCI probe happens before the
device_initcall initialized those service drivers.  The config space state
that the services set up were not being saved.  The end result would cause
PCI devices to not react to events that the drivers think they did if the
PCI state ever needed to be restored.

Fix this by changing the service drivers from using the init calls to
having the portdrv driver calling the services directly.  This will get the
state saved as desired, while making the relationship between the port
driver and the services under it more explicit in the code.

With introduction of MC-aware mode to mlxsw, it became necessary to
configure TCs above 7 as well. There is now code in mlxsw to disable ETS
for these higher classes, but disablement of max shaper was neglected.

By default, max shaper is currently disabled to begin with, so the
problem is just cosmetic. However, for symmetry, do like we do for ETS
configuration, and call mlxsw_sp_port_ets_maxrate_set() for both TC i
and i + 8.

The ucode chunk might be relatively large and the allocation with
kmalloc() may fail occasionally.  Since the data isn't DMA-transferred
but by manual loops, we can use vmalloc instead of kmalloc.
For a better performance, though, kvmalloc() would be the best choice
in such a case, so let's replace with it.

vdso_fault used is_compat_task function (on s390 it tests "current"
thread_info flags) to distinguish compat tasks and map 31-bit vdso
pages. But "current" task might not correspond to mm context.

When 31-bit compat inferior is executed under gdb, gdb does
PTRACE_PEEKTEXT on vdso page, causing vdso_fault with "current" being
64-bit gdb process. So, 31-bit inferior ends up with 64-bit vdso mapped.

To avoid this problem a new compat_mm flag has been introduced into
mm context. This flag is used in vdso_fault and vdso_mremap instead
of is_compat_task.

The AP bus scan is aborted before doing anything worth mentioning if
ap_select_domain() fails, e.g. if the ap_rights.aqm mask is all zeros.
As the result of this the ap bus fails to manage (e.g. create and
register) devices like it is supposed to.

Let us make ap_scan_bus() work even if ap_select_domain() can't select a
default domain. Let's also make ap_select_domain() return void, as there
are no more callers interested in its return value.

The dev_list needs to be protected with a lock, else we may have
simultaneous access (addition/removal) to it and that would be racy.
Extend scope of the opp_table lock to protect dev_list as well.

Commit f27b4746 ("i40iw: add connection management code") uses an
incorrect rcu iterator, whilst holding the rtnl_lock. Since the
critical region invokes i40iw_manage_qhash(), which is a sleeping
function, the rcu locking and traversal cannot be used.

This re-applies commit b91c1e3e ("powerpc: Fix duplicate const
clang warning in user access code") (Jun 2015) which was undone in
commits:
  f2ca8090 ("powerpc/sparse: Constify the address pointer in __get_user_nosleep()") (Feb 2017)
  d466f6c5 ("powerpc/sparse: Constify the address pointer in __get_user_nocheck()") (Feb 2017)
  f84ed59a ("powerpc/sparse: Constify the address pointer in __get_user_check()") (Feb 2017)

We see a large number of duplicate const errors in the user access
code when building with llvm/clang:

  include/linux/pagemap.h:576:8: warning: duplicate 'const' declaration specifier [-Wduplicate-decl-specifier]
        ret = __get_user(c, uaddr);

The problem is we are doing const __typeof__(*(ptr)), which will hit
the warning if ptr is marked const.

Removing const does not seem to have any effect on GCC code
generation.

[ Upstream commit 85a88cab ]

When performing partition migrations all present CPUs must be online
as all present CPUs must make the H_JOIN call as part of the migration
process. Once all present CPUs make the H_JOIN call, one CPU is returned
to make the rtas call to perform the migration to the destination system.

During testing of migration and changing the SMT state we have found
instances where CPUs are offlined, as part of the SMT state change,
before they make the H_JOIN call. This results in a hung system where
every CPU is either in H_JOIN or offline.

To prevent this this patch disables CPU hotplug during the migration
process.

[ Upstream commit 063b8b12 ]

The updates to powerpc numa and memory hotplug code now use the
in-kernel LMB array instead of the device tree. This change allows the
pseries memory DLPAR code to only update the device tree once after
successfully handling a DLPAR request.

Prior to the in-kernel LMB array, the numa code looked up the affinity
for memory being added in the device tree, the code now looks this up
in the LMB array. This change means the memory hotplug code can just
update the affinity for an LMB in the LMB array instead of updating
the device tree.

This also provides a savings in kernel memory. When updating the
device tree old properties are never free'ed since there is no
usecount on properties. This behavior leads to a new copy of the
property being allocated every time a LMB is added or removed (i.e. a
request to add 100 LMBs creates 100 new copies of the property). With
this update only a single new property is created when a DLPAR request
completes successfully.

[ Upstream commit 44d947ef ]

There are cases where the test is not expecting to have the transaction
aborted, but, the test process might have been rescheduled, either in the
OS level or by KVM (if it is running on a KVM guest machine). The process
reschedule will cause a treclaim/recheckpoint which will cause the
transaction to doom, aborting the transaction as soon as the process is
rescheduled back to the CPU. This might cause the test to fail, but this is
not a failure in essence.

If that is the case, TEXASR[FC] is indicated with either
TM_CAUSE_RESCHEDULE or TM_CAUSE_KVM_RESCHEDULE for KVM interruptions.

In this scenario, ignore these two failures and avoid the whole test to
return failure.
