0b42f25d2f Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
udplite conflict is resolved by taking what 'net-next' did
which removed the backlog receive method assignment, since
it is no longer necessary.

Two entries were added to the non-priv ethtool operations
switch statement, one in 'net' and one in 'net-next, so
simple overlapping changes.

 "This resolves the ksyms issues by reverting the commit which
  introduced the breakage"

There was what I consider to be a better fix, but it's late in the rc
game, so I'll take the revert.

8478132a87 Revert "arm: move exports to definitions"
This reverts commit 4dd1837d75.

Moving the exports for assembly code into the assembly files breaks
KSYM trimming, but also breaks modversions.

While fixing the KSYM trimming is trivial, fixing modversions brings
us to a technically worse position that we had prior to the above
change:

- We end up with the prototype definitions divorsed from everything
  else, which means that adding or removing assembly level ksyms
  become more fragile:
  * if adding a new assembly ksyms export, a missed prototype in
    asm-prototypes.h results in a successful build if no module in
    the selected configuration makes use of the symbol.
  * when removing a ksyms export, asm-prototypes.h will get forgotten,
    with armksyms.c, you'll get a build error if you forget to touch
    the file.

- We end up with the same amount of include files and prototypes,
  they're just in a header file instead of a .c file with their
  exports.

As for lines of code, we don't get much of a size reduction:
 (original commit)
 47 files changed, 131 insertions(+), 208 deletions(-)
 (fix for ksyms trimming)
 7 files changed, 18 insertions(+), 5 deletions(-)
 (two fixes for modversions)
 1 file changed, 34 insertions(+)
 3 files changed, 7 insertions(+), 2 deletions(-)
which results in a net total of only 25 lines deleted.

As there does not seem to be much benefit from this change of approach,
revert the change.

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.

That driver has a change_mtu method explicitly for sending
a message to the hardware.  If that fails it returns an
error.

Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.

However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

2a3811068f ARM: Fix XIP kernels
Commit 7619751f8c ("ARM: 8595/2: apply more __ro_after_init") caused
a regression with XIP kernels by moving the __ro_after_init data into
the read-only section.  With XIP kernels, the read-only section is
located in read-only memory from the very beginning.

Work around this by moving the __ro_after_init data back into the .data
section, which will be in RAM, and hence will be writable.

It should be noted that in doing so, this remains writable after init.

This patch moves initialization of DMA-debug to core_initcall. This is
safe from the initialization perspective. dma_debug_do_init() internally calls
debugfs functions and debugfs also gets initialised at core_initcall(), and
that is earlier than arch code in the link order, so it will get initialized
just before the DMA-debug.

24c66dfd56 ARM: fix backtrace
Recent kernels have changed their behaviour to be more inconsistent
when handling printk continuations.  With todays kernels, the output
looks sane on the console, but dmesg splits individual printk()s which
do not have the KERN_CONT prefix into separate lines.

Since the assembly code is not trivial to add the KERN_CONT, and we
ideally want to avoid using KERN_CONT (as multiple printk()s can race
between different threads), convert the assembly dumping the register
values to C code, and have the C code build the output a line at a
time before dumping to the console.

This avoids the KERN_CONT issue, and also avoids situations where the
output is intermixed with other console activity.

DDR3L is usually specified as

	JEDEC standard 1.35V(1.28V~1.45V) & 1.5V(1.425V~1.575V)

Therefore setting smps6 regulator to 1.2V is definitively below
minimum. It appears that real world chips are more forgiving than
data sheets indicate, but let's set the regulator right.

Note: a board that uses other voltages (DDR with 1.5V) can
overwrite by referencing &smps6_reg.

80513a2b9f ARM: omap3: Add missing memory node in SOM-LV
The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

commit ("766a1fe78fc3 ARM: omap3: Add missing memory node") had
fixes for Torpedo and Overo boards, but this SOM-LV was missed.

This should help prevent the DTC warning:
"Node /memory has a reg or ranges property, but no unit name"

LDO3: Bringing 3300000uV into 1800000-1800000uV

The LDO3 voltage constraints passed in the device tree do not match
the valid range according to the datasheet, so fix this accordingly to
allow the board booting again.

While at it, fix the other voltage constraints as well.

94d0e5980d arm/arm64: KVM: Perform local TLB invalidation when multiplexing vcpus on a single CPU
Architecturally, TLBs are private to the (physical) CPU they're
associated with. But when multiple vcpus from the same VM are
being multiplexed on the same CPU, the TLBs are not private
to the vcpus (and are actually shared across the VMID).

Let's consider the following scenario:

- vcpu-0 maps PA to VA
- vcpu-1 maps PA' to VA

If run on the same physical CPU, vcpu-1 can hit TLB entries generated
by vcpu-0 accesses, and access the wrong physical page.

The solution to this is to keep a per-VM map of which vcpu ran last
on each given physical CPU, and invalidate local TLBs when switching
to a different vcpu from the same VM.

10.1.2. Interrupt types and sources says:
"Interrupt is rising-edge sensitive."

The bits seem to be read-only, hence this missconfiguration had
no negative effect. However, with commit 992345a58e
("irqchip/gic: WARN if setting the interrupt type for a PPI fails")
warnings such as this get printed:
GIC: PPI11 is secure or misconfigured

With this change the new configuration matches the default

Instead of returning of_genpd_add_provider_onecell() directly,
we should check its return value and in the case of error we
should unwind the previously taken actions, which in these case are:
- Call imx6q_pm_pu_power_off()
- Set imx6q_pu_domain.reg back to NULL

Setting imx6q_pu_domain.reg to NULL in the error case is important
as it will prevent further operations in the pu_reg regulator.

This kernel crash is not observed with imx_v6_v7_defconfig because
it selects GPU and VPU drivers, which are consumers of the GPC block
and thus change the refcount of the pu_reg regulator.

imx-gpc: probe of 20dc000.gpc failed with error -22

The gpc probe fails because of_genpd_add_provider_onecell() now checks
if all the domains are initialized via pm_genpd_present() function
and it fails because not all the power domains are initialized.

In order to fix this error, initialize all the power domains from

c8ea0395ff arm/arm64: KVM: Map the BSS at HYP
When used with a compiler that doesn't implement "asm goto"
(such as the AArch64 port of GCC 4.8), jump labels generate a
memory access to find out about the value of the key (instead
of just patching the code). The key itself is likely to be
stored in the BSS.

This is perfectly fine, except that we don't map the BSS at HYP,
leading to an exploding kernel at the first access. The obvious
fix is simply to map the BSS there (which should have been done
a long while ago, but hey...).

04946fb60f ARM: fix oops when using older ARMv4T CPUs
Alexander Shiyan reports that CLPS711x fails at boot time in the data
exception handler due to a NULL pointer dereference.  This is caused by
the late-v4t abort handler overwriting R9 (which becomes zero).  Fix
this by making the abort handler save and restore R9.

Instead of having the smc91x driver relying on machine_is_*() calls,
provide this data through platform data, ie. idp, mainstone and

This way, the driver doesn't need anymore machine_is_*() calls, which
wouldn't work anymore with a device-tree build.

1b283eea62 ARM: dts: fix the SD card on the Snowball
This fixes a very annoying regression on the Snowball SD card
that has been around for a while. It turns out that the device
tree does not configure the direction pins properly, nor sets
up the pins for the voltage converter properly at boot. Unless
all things are correctly set up, the feedback clock will not
work, and makes the driver spew messages in the console (but
it works, very slowly):

root@Ux500:/ mount /dev/mmcblk0p2 /mnt/
[    9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!
[    9.960296] mmcblk0: error -110 sending status command, retrying
[    9.966461] mmcblk0: error -110 sending status command, retrying
[    9.972534] mmcblk0: error -110 sending status command, aborting

Fix this by rectifying the device tree to correspond to that of
the Ux500 HREF boards plus the DAT31DIR setting that is unique for
the Snowball, and things start working smoothly. Add in the SDR12
and SDR25 modes which this host can do without any problems.

I don't know if this has ever been correct, sadly. It works after
this patch.
