Further generalise the decompressors by adding a page handler

to access and process the output buffers in an implementation
independant manner.
This allows different types of output buffer to be passed

This introduces an implementation of squashfs_readpage_block()

With multiple, concurrent readers (each waiting to acquire the
atomic_read_lock mutex), a departing reader may mistakenly reset
minimum_to_wake after a new reader has already set a new value.
Protect the minimum_to_wake reset with the atomic_read_lock critical

A departing reader must restart a flush_to_ldisc() worker _before_
the next reader enters the read loop; this is to avoid the new reader
concluding no more i/o is available and prematurely exiting, when the
old reader simply hasn't re-started the worker yet.

This patch adds a check for USB_STATE_NOTATTACHED to the
hub_port_warm_reset_required() workaround for ports that end up in
Compliance Mode in hub_events() when trying to decide which reset
function to use. Trying to call usb_reset_device() with a NOTATTACHED
device will just fail and leave the

The commit 712b6aa8731a7e148298c58cea66a5209c659e3c [Nov7 linux-next
via tip/auto-latest] ("intel_mid: Renamed *mrst* to *intel_mid*")
adds a __cpuinit.
We removed this a couple versions ago; we now want to remove
the compat no-op stubs. Introducing new users is not what
we want to see at this

We currently have a confusing couple of API naming with the existing
context_tracking_active() and context_tracking_is_enabled().
Lets keep the latter one, context_tracking_is_enabled(), for global
context tracking state check and use context_tracking_cpu_is_enabled()
for local state check.
After a posix cpu timer is set, a workqueue is scheduled in order to
kick the full dynticks CPUs and let them restart their tick if
necessary in case the task they are running is concerned by the
new timer.
This kick is implemented by way of IPIs, which require interrupts
to be enabled, hence the
Hi,
This is a bunch of improvements and cleanups for dynticks.
If no comment arise I'll send this to Ingo in a few days.

It passed through 0-day testing with success.
Thanks,

Use a function with a meaningful name to check the global context
tracking state. static_key_false() is a bit confusing for reviewers.

A posix CPU timer can be rearmed while it is firing or after it is
notified with a signal. This can happen for example with timers that
were set with a non zero interval in timer_settime().
This rearming can happen in two places:
1) On timer firing time, which happens on the target's tick. If

A few functions use remote per CPU access APIs when they
deal with local values.
Just to the right conversion to improve performance, code
readability and debug checks.

In some use cases Zynq's FPGA clocks are used as static clock
generators for IP in the FPGA part of the SOC for which no Linux driver
exists and would control those clocks. To avoid automatic
gating of these clocks in such cases a new property - fclk-enable - is
added to the clock controller's DT

Hi,
this is v3. The only change is a doc fix. Regarding the vendor prefix for
properties, I counted one vote for it and one against + the already existing
bindings that don't have a vendor prefix and my personal preference; and nobody
else seems to have a strong opinion on this. Therefore I left

of "8350_core" instead of "8250_core", so correct it.
