"The i.MX clock updates for 4.4:
- A couple of fixes on i.MX31 and i.MX35 clock initialization functions
which makes mxc_timer_init() currently be called twice for DT boot.
- Increase i.MX6UL AXI bus clock rate to 264MHz which is the optimal

- Add a few missing clocks, ADC clock for i.MX7D, OCOTP clock for
Vybrid, and SPDIF_GCLK for i.MX6.
- A series from Lucas to fix early debug UART clock setup. This is
currently a one-off fix for i.MX platform, and can be extended to

clk: Make of_clk_get_parent_name() robust with #clock-cells = 1
If a clock provider has #clock-cells = 1 and we call
of_clk_get_parent_name() on it we may end up returning the name
of the provider node if the provider doesn't have a
clock-output-names property. This doesn't make sense, especially
when you consider that calling of_clk_get_parent_name() on such a
node with different indices will return the same name each time.
Let's try getting the clock from the framework via of_clk_get()
instead, and only fallback to the node name if we have a provider
with #clock-cells = 0. This way, we can't hand out the same name
for different clocks when we don't actually know their names.

eca61c9ff2588e1df373e61078e1874976315839.
Thomas reports that it causes regressions on Armada XP devices.
This is because of_clk_get_parent_name() relies on the property
'clock-output-names' to resolve the name of a clock's parent,
without trying to get the clock from the framework and call
__clk_get_name(). Given that Armada XP devices don't have the
'clock-output-names' property, of_clk_get_parent_name() returns
the name of the node which doesn't match the actual parent
clock's name at all, causing CPU clocks to never link up with
their parents.

This adds support for enabling, disabling, and setting the rate of the

for HDMI in the VC4 driver and let us write a cpufreq driver. It will
also improve compatibility with user changes to the firmware's
config.txt, since our previous fixed clocks are unaware of it.
The firmware also has support for configuring the clocks through the
mailbox channel, but the pixel clock setup by the firmware doesn't
work, and it's Raspberry Pi specific anyway. The only conflicts we
should have with the firmware would be if we made firmware calls that
result in clock management (like opening firmware V3D or ISP access,
which we don't support in upstream), or on hardware over-thermal or
under-voltage (when the firmware would rewrite PLLB to take the ARM
out of overclock). If that happens, our cached .recalc_rate() results
would be incorrect, but that's no worse than our current state where
we used fixed clocks.
The existing fixed clocks in the code are left in place to provide
backwards compatibility with old device tree files.

We found an issue that imx can't enter low power mode with spdif
if IMX6x_CLK_SPDIF is used as the core clock of spdif. Because
spdif driver will register IMX6x_CLK_SPDIF clock to regmap, regmap will do
clk_prepare in init function, then IMX6x_CLK_SPDIF clock is prepared in probe,
so its parent clock (PLL clock) is prepared, the prepare operation of
PLL clock is to enable the clock. But I.MX needs all PLL clock is disabled,
then it can enter low power mode.
So we can't use IMX6x_CLK_SPDIF as the core clock of spdif, the correct spdif
core clock is SPDIF_GCLK, which share same gate bit with IMX6x_CLK_SPDIF clock.

bootloader execute tuning for HS200 mode. It might make kernel failed
to initialize mmc card in identification mode. The root cause is
tuning phase and degree setting for HS200 mode in bootloader aren't
applicable to that of identification mode in kernel stage. Anyway, we
can't force all bootloaders to reset tuning phase and degree setting
before into kernel. Simply reset it in rockchip_clk_register_mmc.

clk:mxs: Fix bug on frequency divider
On drivers/clk/mxs/clk-frac.c, the function clk_frac_round_rate returned a bad
result. The division before multiplication computes a wrong value ; the
calculation is inverted to fix the problem. The second issue is that the exact
rate have decimals and they are truncate. The consequence is that the function
clk_frac_set_rate (which use the result of clk_frac_round_rate) computes a
wrong value for the register (the rate generated can be closer to the desired
rate). The correction is : if there is decimal to the result, it is rounded to
the next larger integer.
On drivers/clk/mxs/clk-frac.c, the function clk_frac_recalc_rate returned
a bad result. The multiplication is made before the division to compute a
correct value.

"This ended up with a larger set of fixes than wished, unfortunately.
As diffstat shows, the majority of changes are for various ASoC

of HD-audio regression fixes. All these are reasonably small and
nothing to scare much"

We observed some performance degradation on s390x with dynamic
halt polling. Until we can provide a proper fix, let's enable
halt_poll_ns as default only for supported architectures.
Architectures are now free to set their own halt_poll_ns
default value.

KVM: x86: fix off-by-one in reserved bits check
29ecd6601904 ("KVM: x86: avoid uninitialized variable warning",
2015-09-06) introduced a not-so-subtle problem, which probably
escaped review because it was not part of the patch context.
Before the patch, leaf was always equal to iterator.level. After,
it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set,
and when is_shadow_zero_bits_set does another "-1" the check on
reserved bits becomes incorrect. Using "iterator.level" in the call
fixes this call trace:

KVM: x86: use correct page table format to check nested page table reserved bits
Intel CPUID on AMD host or vice versa is a weird case, but it can
happen. Handle it by checking the host CPU vendor instead of the
guest's in reset_tdp_shadow_zero_bits_mask. For speed, the
check uses the fact that Intel EPT has an X (executable) bit while
AMD NPT has NX.

kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the

is ugly, and adding it to kvm_arch_vcpu_create doesn't work because
the VMX vcpu_create callback calls synchronize_srcu.

iscsi-target: Avoid OFMarker + IFMarker negotiation
This patch fixes a v4.2+ regression introduced by commit
c04a6091
that removed support for obsolete sync-and-steering markers usage
as originally defined in RFC-3720.
The regression would involve attempting to send OFMarker=No +
IFMarker=No keys during opertional negotiation login phase,
including when initiators did not actually propose these keys.
The result for MSFT iSCSI initiators would be random junk in
TCP stream after the last successful login request was been sent
signaling the move to full feature phase (FFP) operation.
To address this bug, go ahead and avoid negotiating these keys
by default unless the initiator explicitly proposes them, but
still respond to them with 'No' if they are proposed.
