This reverts commit 0ade4a34fd439d62df46937e8f3e584eb0879579.
This patch removes kfree for serial_ports in dgap_tty_register_ports()
if the "brd->printer_ports" allocation fails and serial_ports may be
freed by calling dgap_tty_uninit() within other patch.
That patch has an error handling but

This patch adds notification infrastructure for any requests related to cooling
states. The notifier structure passed is of both Get/Set type. So the receiver
of these can sense the new/cur/max cooling state as decided by thermal governor.
In addition to that it can also override the cooling state
Changes since RFC:
* Moved the cooling state notification support to thermal core from cpu cooling
as suggested by Eduardo.
* Used per cpu notifier structure in the cpufreq cooling implementation. This
is a fix for race condition.
* One more comment from Eduardo was to take care when multiple
This is required as with the addition of the cooling notifiers mechanism the
client can enable some more cooling states at a later point of time and
hence max cooling state is dynamic entity now. Say when minimum p state
is reached then ACPI specific throttling is enabled which may add some
more
This patch upgrades the ACPI cpufreq cooling portions to use the generic
cpufreq cooling infrastructure. There should not be any functionality
related changes as the same behaviour is provided by the generic
cpufreq APIs with the notifier mechanism.

This patch adds support to get P state ceil/floor level for nearest frequency.

Currently the notification data is supplied to the thermal notifiers using
a single global pointer. This method will have race condition if cpu cooling
interfaces are used by more than 1 clients (more than 1 cdev) to cause cpufreq
clipping. Also the notifier data is presented as per cpu cpufreq
This patch allows the caller of cpufreq cooling APIs to register along
with their driver data which will be useful while receiving any cooling states
notifications.
This patch is in preparation to add notfication support for cpufrequency
cooling changes. This change also removes the unnecessary

kgdb_nmi_tty_enabled is used for two unrelated purposes, namely to

That's what this patch
This corrects a crash in kgdb_nmi_tty_shutdown() which occurs when
the function is called with port->tty set to NULL.
All conversions between struct tty_port and struct kgdb_nmi_tty_priv
have been switched to direct calls to container_of() to improve code
clarity and consistancy.

This patchset contains a number of fixes to make it possible to use
ttyNMIX as the primary console (providing you also have that the
additional architecture specific code which is proposed in a
different patch set).
The first patch fixes a bug in the cpm poll_put_char() driver. This
is not

kgdb_nmi uses tasklets on the assumption they will not be scheduled
until the next timer tick. This assumption is invalid and can lead to
live lock, continually servicing the kgdb_nmi tasklet. This is fixed
by using the timer API instead.

This is a rearranged version of the original patchset, according to the

Hi,
this patchset introduces the last version of BFQ, a proportional-share
We have found four sources of throughput loss and higher
latencies. First, write requests tend to starve read requests,
basically because, on one side, writes are slower than reads, whereas,
on the other side, storage devices confuse schedulers by deceptively
signaling the completion of write

This patch introduces an heuristic that reduces latency when the
I/O-request pool is saturated. This goal is achieved by disabling
device idling, for non-weight-raised queues, when there are weight-
raised queues with pending or in-flight requests. In fact, as
explained in more detail in the

Hi Andrew,
Today's linux-next merge of the akpm-current tree got a conflict in
kernel/kexec.c between commit 011e4b02f1da ("powerpc, kexec: Fix
"Processor X is stuck" issue during kexec from ST mode") from Linus'
tree and commit 51950fcb6d27 ("kernel/kexec.c: convert printk to
pr_foo()") from the
I/O schedulers typically allow NCQ-capable drives to prefetch I/O
requests, as NCQ boosts the throughput exactly by prefetching and
internally reordering requests.
Unfortunately, as discussed in detail and shown experimentally in [1],
this may cause fairness and latency guarantees to be violated.
Unless the maximum budget B_max that BFQ can assign to a queue is set
explicitly by the user, BFQ automatically updates B_max. In
particular, BFQ dynamically sets B_max to the number of sectors that
can be read, at the current estimated peak rate, during the maximum
time, T_max, allowed before a
1001 - 1100 of 1878 matches
