Tony Lindgren a015818579 ARM: dts: Fix missing entries for am3517
On am3517 there are some extra devices compared to omap3.dtsi that
we currently have not defined. Let's fix that by adding am3517.dtsi
file.

Tony Lindgren 5e863c5610 ARM: OMAP2+: Fix overwriting hwmod data with data from device tree
We have some device tree properties where the ti,hwmod have multiple
values:

am33xx.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
am4372.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
dra7.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2";
omap3.dtsi:	ti,hwmods = "mcbsp2", "mcbsp2_sidetone";
omap3.dtsi:	ti,hwmods = "mcbsp3", "mcbsp3_sidetone";
omap4.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
omap5.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";

That's not correct way of doing things in this case because these are
separate devices with their own address space, interrupts, SYSCONFIG
registers and can set their PM states independently.

So they should all be fixed up to be separate devices in the .dts files.

We also have the related data removed for at least omap4 in commit
3b9b10151c (ARM: OMAP4: hwmod data: Clean up the data file), so
that data is wrongly initialized as null data.

So we need to fix two bugs:

1. We are only checking the first entry of the ti,hwmods property

   This means that we're only initializing the first hwmods entry
   instead of the ones listed in the ti,hwmods property.

2. We are only checking the child nodes, not the nodes themselves

   This means that anything listed at OCP level is currently just
   ignored and unitialized and at least the omap4 case, with the
   legacy data missing from the hwmod.

Fix both of the issues by using an index to the ti,hwmods property
and changing the hwmod lookup function to also check the current node
for ti,hwmods property instead of just the children.

While at it, let's also add some warnings for the bad data so it's
easier to fix.

Ezequiel Garcia a328f3a059 net: mvneta: Fix incorrect DMA unmapping size
The current code unmaps the DMA mapping created for rx skb_buff's by
using the data_size as the the mapping size. This is wrong since the
correct size to specify should match the size used to create the mapping.

This commit removes the following DMA_API_DEBUG warning:

Jiri Pirko 859828c0ea br: fix use of ->rx_handler_data in code executed on non-rx_handler path
br_stp_rcv() is reached by non-rx_handler path. That means there is no
guarantee that dev is bridge port and therefore simple NULL check of
->rx_handler_data is not enough. There is need to check if dev is really
bridge port and since only rcu read lock is held here, do it by checking
->rx_handler pointer.

Note that synchronize_net() in netdev_rx_handler_unregister() ensures
this approach as valid.

Introduced originally by:
commit f350a0a873
  "bridge: use rx_handler_data pointer to store net_bridge_port pointer"

Fixed but not in the best way by:
commit b5ed54e94d
  "bridge: fix RCU races with bridge port"

Reintroduced by:
commit 716ec052d2
  "bridge: fix NULL pointer deref of br_port_get_rcu"

Please apply to stable trees as well. Thanks.

- there is enough space after the transport header offset for a

During suspend-resume and lancer error recovery we will cleanup and
re-initialize the resources through be_clear() and be_setup() respectively.
During re-initialisation in be_setup(), if be_get_config() fails, we'll again
call be_clear() which will cause a NULL pointer dereference as adapter->pmac_id is
already freed.

Catalin Marinas 2f7dc60275 arm64: Fix memory shareability attribute for ioremap_wc/cache
Write-combine and cacheable mappings use Normal memory on arm64. On SMP
systems, the pte needs the shareability bit which is set in
pgprot_default. Use this for defining PROT_DEFAULT used by ioremap_wc
and ioremap_cache (Device memory is shareable by default, does not need
additional attributes).

Lorenzo Pieralisi 85cc00eaa8 arm64: kernel: add code to set cpu boot mode to secondary_entry shim
The refactoring of el2_setup split code setting up EL2 and detecting the
CPU boot mode in separate chunks. This allows the code that sets up EL2 to
run in an endian independent way - ie before the endianess is set up in
the respective sctlr registers.

This patch brings secondary_entry up-to-date so that CPUs entering the
kernel through this code path set-up EL2 and the cpu boot mode properly.

Mark Rutland 3cea71bc6b arm64: ensure completion of TLB invalidatation
Currently there is no dsb between the tlbi in __cpu_setup and the write
to SCTLR_EL1 which enables the MMU in __turn_mmu_on. This means that the
TLB invalidation is not guaranteed to have completed at the point
address translation is enabled, leading to a number of possible issues
including incorrect translations and TLB conflict faults.

This patch moves the tlbi in __cpu_setup above an existing dsb used to
synchronise I-cache invalidation, ensuring that the TLBs have been
invalidated at the point the MMU is enabled.

When creating IO mappings, we lazily allocate our page tables using the
standard, non-atomic allocator functions. This presents us with a
problem, since our page tables are protected with a spinlock.

This patch reworks the smmu_domain lock to use a mutex instead of a
spinlock. iova_to_phys is then reworked so that it only reads the page
tables, and can run in a lockless fashion, leaving the mutex to guard
against concurrent mapping threads.

Linus Torvalds 843f4f4bb1 A regression showed up that there's a large delay when enabling
all events. This was prevalent when FTRACE_SELFTEST was enabled which
 enables all events several times, and caused the system bootup to
 pause for over a minute.
 
 This was tracked down to an addition of a synchronize_sched() performed
 when system call tracepoints are unregistered.
 
 The synchronize_sched() is needed between the unregistering of the
 system call tracepoint and a deletion of a tracing instance buffer.
 But placing the synchronize_sched() in the unreg of *every* system call
 tracepoint is a bit overboard. A single synchronize_sched() before
 the deletion of the instance is sufficient.

Eric W. Biederman 7f2cbdc28c tcp_memcontrol: Cleanup/fix cg_proto->memory_pressure handling.
kill memcg_tcp_enter_memory_pressure.  The only function of
memcg_tcp_enter_memory_pressure was to reduce deal with the
unnecessary abstraction that was tcp_memcontrol.  Now that struct
tcp_memcontrol is gone remove this unnecessary function, the
unnecessary function pointer, and modify sk_enter_memory_pressure to
set this field directly, just as sk_leave_memory_pressure cleas this
field directly.

This fixes a small bug I intruduced when killing struct tcp_memcontrol
that caused memcg_tcp_enter_memory_pressure to never be called and
thus failed to ever set cg_proto->memory_pressure.

Remove the cg_proto enter_memory_pressure function as it now serves
no useful purpose.

Don't test cg_proto->memory_presser in sk_leave_memory_pressure before
clearing it.  The test was originally there to ensure that the pointer
was non-NULL.  Now that cg_proto is not a pointer the pointer does not
matter.

Tony Lindgren dd0df47dc3 net: davinci_emac: Fix platform data handling and make usable for am3517
When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.

Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.

Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e0076a (net: davinci_emac: switch to

Jamal Hadi Salim says:

====================
net_sched: actions - Add default lookup and walker

This set of patches provide defaults for lookup and walkers for actions.
Users can override when needed.
It also enforces mandatory action methods to be passed.

Thanks to David Miller who paid attention and made this patch set
much better.
