As we are going to introduce support for Armada 38x in pm.c, split out
the Armada XP part of mvebu_pm_store_bootinfo() into
mvebu_pm_store_armadaxp_bootinfo(), and make the former retunr an
error when an unsupported SoC is used.

The mvebu_pm_init() initializes the support for suspend/resume, and
before doing that, it checks if we are on a board on which
suspend/resume is actually supported. However, this check is already
done by mvebu_armada_xp_gp_pm_init(), and there is no need to
duplicate the check: callers of mvebu_pm_init() should now what they
are doing.
This commit is done in preparation to the addition of suspend/resume
support on Armada 38x.

This patch prepares the set_cpu_coherent() function in coherency.c to
be extended to support other SoCs than Armada XP. It will be needed on
Armada 38x to re-enable the coherency after exiting from suspend to
RAM.
This preparation simply moves the function further down in coherency.c
so that it can use coherency_type(), and uses that function to only do
the Armada XP specific work if we are on Armada XP.

Add an extension to the heavy barrier code to allow a SoC specific
memory barrier function to be provided. This is needed for platforms
where the interconnect has weak ordering, and thus needs assistance
to ensure that memory writes are properly visible in the correct order
to other parts of the system.

The existing memory barrier macro causes a significant amount of code
to be inserted inline at every call site. For example, in
gpio_set_irq_type(), we have this for mb():
c0344c08: f57ff04e dsb st
c0344c0c: e59f8190 ldr r8, [pc, #400] ; c0344da4 <gpio_set_irq_type+0x230>
c0344c10: e3590004 cmp r9, #4
c0344c14: e5983014 ldr r3, [r8, #20]
c0344c18: 0a000054 beq c0344d70 <gpio_set_irq_type+0x1fc>
c0344c1c: e3530000 cmp r3, #0
c0344c20: 0a000004 beq c0344c38 <gpio_set_irq_type+0xc4>
c0344c24: e50b2030 str r2, [fp, #-48] ; 0xffffffd0
c0344c28: e50bc034 str ip, [fp, #-52] ; 0xffffffcc
c0344c2c: e12fff33 blx r3
c0344c30: e51bc034 ldr ip, [fp, #-52] ; 0xffffffcc
c0344c34: e51b2030 ldr r2, [fp, #-48] ; 0xffffffd0
c0344c38: e5963004 ldr r3, [r6, #4]
Moving the outer_cache_sync() call out of line reduces the impact of
the barrier:
c0344968: f57ff04e dsb st
c034496c: e35a0004 cmp sl, #4
c0344970: e50b2030 str r2, [fp, #-48] ; 0xffffffd0
c0344974: 0a000044 beq c0344a8c <gpio_set_irq_type+0x1b8>
c0344978: ebf363dd bl c001d8f4 <arm_heavy_mb>
c034497c: e5953004 ldr r3, [r5, #4]
This should reduce the cache footprint of this code. Overall, this
results in a reduction of around 20K in the kernel size:
text data bss dec hex filename
10773970 667392 10369656 21811018 14ccf4a ../build/imx6/vmlinux-old
10754219 667392 10369656 21791267 14c8223 ../build/imx6/vmlinux-new
Another advantage to this approach is that we can finally resolve the
issue of SoCs which have their own memory barrier requirements within
multiplatform kernels (such as OMAP.) Here, the bus interconnects
need additional handling to ensure that writes become visible in the
correct order (eg, between dma_map() operations, writes to DMA
coherent memory, and MMIO accesses.)

Before this commit the code for determining the disconnect threshold was
checking for "allwinner,sun4i-a10-usb-phy" or "allwinner,sun6i-a31-usb-phy"
assuming that those where the exception and then newer SoCs would use a
disconnect threshold of 2 like sun7i does. But it turns out that newer
SoCs use a disconnect threshold of 3 and sun5i and sun7i are the
exceptions, so check for those instead.
Here are the settings from the various Allwinner SDK sources:

Intel Wired LAN Driver Updates 2015-07-23
This series contains updates to e1000e, igb, ixgbevf, i40e and i40evf.
Emil extends the reporting of the RSS key and hash table by adding support
for x550 VFs.
Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a
call to pm_qos_remove_request() to cleanup the QoS request made in
e1000_open().
Todd updates igb to report unsupported for ethtool coalesce settings
that are not supported. Also updated the driver to use the ARRAY_SIZE()
macro.
Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf
which would never change dynamically. So update the switch() statement
to have a default case and switch on "new_latency_range" versus the
current ITR setting.
Shannon cleans up i40e code, where there were un-needed goto's. Also
clean up error status messages that were causing some confusion in
PHY and FCoE setup error reports.
Mitch updates the virtual channel interface to prepare for the x722 device
and other future devices, so that the VF driver can report what its
capable of supporting to the PF driver. Updates the i40evf driver to
handle resets like Core or EMP resets, where the device is reinitialized
and the VF will not get the same VSI.
Jesse updates the i40e and i40evf driver to use the kernel BIT() and
BIT_ULL() macros.

ipv4: fib_select_default changes
This patchset contains 2 changes for the alternative routes,
one to add tb_id/fa_slen check needed after the recent
fib_trie optimizations for fib aliases and the second
change attempts to support alternative routes with TOS
requirement.
Sorry that I don't have access to the original
report from Hagen Paul Pfeifer. I hope he will see this
change.
The second change adds fa_default field to the
fib aliases (which can be many) and if the feature to
filter the alternative routes by TOS is not worth it,
this second patch can be scrapped.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
fib_select_default considers alternative routes only when
res->fi is for the first alias in res->fa_head. In the
common case this can happen only when the initial lookup
matches the first alias with highest TOS value. This
prevents the alternative routes to require specific TOS.
This patch solves the problem as follows:
- routes that require specific TOS should be returned by
fib_select_default only when TOS matches, as already done
in fib_table_lookup. This rule implies that depending on the
TOS we can have many different lists of alternative gateways
and we have to keep the last used gateway (fa_default) in first
alias for the TOS instead of using single tb_default value.
- as the aliases are ordered by many keys (TOS desc,
fib_priority asc), we restrict the possible results to
routes with matching TOS and lowest metric (fib_priority)
and routes that match any TOS, again with lowest metric.
For example, packet with TOS 8 can not use gw3 (not lowest
metric), gw4 (different TOS) and gw6 (not lowest metric),
all other gateways can be used:
tos 8 via gw1 metric 2 <--- res->fa_head and res->fi
tos 8 via gw2 metric 2
tos 8 via gw3 metric 3
tos 4 via gw4
tos 0 via gw5
tos 0 via gw6 metric 1

cpufreq_rwsem was introduced in commit 6eed9404ab ("cpufreq: Use
rwsem for protecting critical sections) in order to replace
try_module_get() on the cpu-freq driver. That try_module_get() worked
well until the refcount was so heavily used that module removal became
more or less impossible.
Though when looking at the various (undocumented) protection
mechanisms in that code, the randomly sprinkeled around cpufreq_rwsem
locking sites are superfluous.
The policy, which is acquired in cpufreq_cpu_get() and released in
cpufreq_cpu_put() is sufficiently protected already.
cpufreq_cpu_get(cpu)
/* Protects against concurrent driver removal */
read_lock_irqsave(&cpufreq_driver_lock, flags);
policy = per_cpu(cpufreq_cpu_data, cpu);
kobject_get(&policy->kobj);
read_unlock_irqrestore(&cpufreq_driver_lock, flags);
The reference on the policy serializes versus module unload already:
cpufreq_unregister_driver()
subsys_interface_unregister()
__cpufreq_remove_dev_finish()
per_cpu(cpufreq_cpu_data) = NULL;
cpufreq_policy_put_kobj()
If there is a reference held on the policy, i.e. obtained prior to the
unregister call, then cpufreq_policy_put_kobj() will wait until that
reference is dropped. So once subsys_interface_unregister() returns
there is no policy pointer in flight and no new reference can be
obtained. So that rwsem protection is useless.
The other usage of cpufreq_rwsem in show()/store() of the sysfs
interface is redundant as well because sysfs already does the proper
kobject_get()/put() pairs.
That leaves CPU hotplug versus module removal. The current
down_write() around the write_lock() in cpufreq_unregister_driver() is
silly at best as it protects actually nothing.
The trivial solution to this is to prevent hotplug across
cpufreq_unregister_driver completely.

This patch changes some variables to avoid warnings from ninja-check.
We are basically moving some variables inside the conditionals where
such variables are being used, and we are checking the returned values
of some others.

This patch simply reorders the entries found in the new keymap by
ascending order, this is simply a cosmetic change, no functionality
was modified.

Commit 2b74103547 ("toshiba_acpi: Remove bluetooth rfkill code")
removed bluetooth related code, however, the wireless defines were
not removed and are unused.
This patch simply removes those defines as there is no code using
them.

This patch fixes a bug in iser-target code where the REJECT CM event
handler code currently performs a isert_put_conn() for the final
isert_conn->kref put, while iscsi_np process context is still blocked
in isert_get_login_rx().
Once isert_get_login_rx() is awoking due to login timeout, iscsi_np
process context will attempt to invoke iscsi_target_login_sess_out()
to cleanup iscsi_conn as expected, and calls isert_wait_conn() +
isert_free_conn() which triggers the use-after-free OOPs.
To address this bug, move the kref_get_unless_zero() call from
isert_connected_handler() into isert_connect_request() immediately
preceeding isert_rdma_accept() to ensure the CM handler cleanup
paths and isert_free_conn() are always operating with two refs.

This patch fixes a regression introduced with the following commit
in v4.0-rc1 code, where an explicit iser-target logout would result
in ->tx_thread_active being incorrectly cleared by the logout post
handler, and subsequent TX kthread leak:

iscsi-target: Convert iscsi_thread_set usage to kthread.h
To address this bug, change iscsit_logout_post_handler_closesession()
and iscsit_logout_post_handler_samecid() to only cmpxchg() on
->tx_thread_active for traditional iscsi/tcp connections.
This is required because iscsi/tcp connections are invoking logout
post handler logic directly from TX kthread context, while iser
connections are invoking logout post handler logic from a seperate
workqueue context.
