clk: avoid circular clock topology
Currently, clk_register() never checks a circular parent looping,
but clock providers could register such an insane clock topology.
For example, "clk_a" could have "clk_b" as a parent, and vice versa.
In this case, clk_core_reparent() creates a circular parent list
and __clk_recalc_accuracies() calls itself recursively forever.
The core infrastructure should be kind enough to bail out, showing
an appropriate error message in such a case. This helps to easily
find a bug in clock providers. (uh, I made such a silly mistake
when I was implementing my clock providers first. I was upset
because the kernel did not respond, without any error message.)
This commit adds a new helper function, __clk_is_ancestor(). It
returns true if the second argument is a possible ancestor of the
first one. If a clock core is a possible ancestor of itself, it
would make a loop when it were registered. That should be detected
as an error.

Currently, __clk_core_init() allows failure of the kcalloc() for the

complicated.
Like other clk_core members, allocate core->parents in clk_register()
and let it fail in case of memory shortage. If we cannot allocate
such a small piece of memory, the system is already insane. There is
no point to postpone the memory allocation.
Also, allocate core->parents regardless of core->num_parents. We want
it even if core->num_parents == 1 because clk_fetch_parent_index()
might be called against the clk_core with a single parent.

clk-divider: make sure read-only dividers do not write to their register
Commit
e6d5e7d90be9 ("clk-divider: Fix READ_ONLY when divider > 1") removed
the special ops struct for read-only clocks and instead opted to handle
them inside the regular ops.
On the rk3368 this results in breakage as aclkm now gets set a value.
While it is the same divider value, the A53 core still doesn't like it,
which can result in the cpu ending up in a hang.
The reason being that "ACLKENMasserts one clock cycle before the rising
edge of ACLKM" and the clock should only be touched when STANDBYWFIL2
is asserted.
To fix this, reintroduce the read-only ops but do include the round_rate
callback. That way no writes that may be unsafe are done to the divider
register in any case.
The Rockchip use of the clk_divider_ops is adapted to this split again,
as is the nxp, lpc18xx-ccu driver that was included since the original
commit. On lpc18xx-ccu the divider seems to always be read-only
so only uses the new ops now.

clk: tegra: Remove improper flags for lock_enable
Most PLL's don't actually have LOCK_ENABLE bits. However, most PLL's
also had that flag set, which meant that the clk code was trying to
enable locks, and inadvertantly flipping bits in other fields.
For PLLM, ensure the correct register is used for the misc_register.
PLL_MISC0 contains the EN_LCKDET bit which should be used for enabling
the lock, and PLLM_MISC1 shouldn't be used at all.
Lastly, remove some of the settings which would point to the EN_LCKDET
bits for some PLLs. There is no need to enable the locks, and that is
done as part of the set_defaults logic already.

vmstat: Remove BUG_ON from vmstat_update
If we detect that there is nothing to do just set the flag and do not
check if it was already set before. Races really do not matter. If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.
Since commit
0eb77e988032 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd. This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up. The VM_BUG_ON is therefore misleading and no more
appropriate. Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly. Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

MIPS: Move KVM specific opcodes into asm/inst.h
The header arch/mips/kvm/opcode.h defines a few extra opcodes which
aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM
specific about them, so lets move them into inst.h where they belong and
delete the header.
Note that mfmcz_op is renamed to mfmc0_op to match the instruction set
manual, and wait_op was already added to inst.h in commit
b0a3eae2b943
("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.
