As we move from no clients/consumers in kernel voting on corners,

where the clients which remove votes can adversly impact others

To avoid this situation, have a max vote on all corners at init
The Power domains for corners just pass the performance state set by the

Hi,
Thanks for the report. This patch should go on
When try_module_get fails, the lack of error-handling code may
cause unexpected results.
This patch adds error-handling code after calling try_module_get.

The current FSI scom driver is a bit too simplistic (and buggy). This
fixes a locking bug, cleans a few things up, then overhaul the driver
more thoroughly by providing proper support for the different type
of SCOM accesses (direct and indirect), handling errors properly in
the read/write interface
Otherwise, multiple clients can open the driver and attempt
to access the PIB at the same time, thus clobbering each other
in the process.

Currently the driver assumes that the interrupts are continuous
and does platform_get_irq only once and assumes the rest are continuous,
instead call platform_get_irq for all the interrupts and store them
in an array for later use.

GRX500 family.

Previous implementation uses a hard-coded register value to check if
the current serial entity is the console entity.
Now the lantiq serial driver uses the aliases for the index of the
serial port.
The lantiq danube serial dts are updated with aliases to support this.

Previous implementation uses one global lock to protect the resource.
If the serial driver have multiple entries, this kind of lock will
slow down the performance.
Add the lock at device level. This will lock only when the function

So that it can avoid useless lock
Previous implementation uses platform-dependent functions

I think the prime issue is that dma_direct_alloc respects the dma
mask. Which we don't need if actually using the iommu. This would
be mostly harmless exept for the the SEV bit high in the address that

Some ASUS laptops like UX550GE has hotkey (Fn+F7) for keyboard
backlight toggle which would emit the scan code 0xc7 each keypress.
On the UX550GE, the max keyboard brightness level is 3 so the
toggle would not be simply on/off the led but need to be cyclic.
Per ASUS spec, it should increment the br
Make asus-wmi notify on hotkey kbd brightness changes, listen for
brightness events and update the brightness directly in the driver.
For this purpose, bound check on brightness in kbd_led_set must be
based on the same data type to prevent illegal value been set.
Update the brightness by led_class

On s390 the socket identifier assigned to a CPU identifier is
random and (depending on the configuration of the LPAR) may be higher
than the CPU identifier. This is currently not supported.
Fix this by allowing arbitrary socket identifiers being assigned to
CPU id.
Output before:
[root@p23lp27 p
On s390 this test case fails because the socket identifiction numbers
assigned to the CPU are higher than the CPU identification numbers.
Fix this by adding the platform architecture into the perf data header
flag information. This helps identifiing the test platform and handles
s390 specifics in

After detecting pause loop which is executed by a Lock Waiter in the
guest, the pCPU will be yielded to a Lock Holder candidate, the Lock
Holder candidate may have its own task affinity constrain, however,
current yield logic yield to the Lock Holder condidate unconditionally

Consider the task afffinity constrain when yield to a task.

When snd_ctl_add fails, the lack of error-handling code may
cause unexpected results.
This patch adds error-handling code after calling snd_ctl_add.

The max number of slots used in xennet_get_responses() is set to
MAX_SKB_FRAGS + (rx->status <= RX_COPY_THRESHOLD).
In old kernel-xen MAX_SKB_FRAGS was 18, while nowadays it is 17. This
difference is resulting in frequent messages "too many slots" and a
reduced network throughput for some workload
