The formula is OK. But it may overflow while we do operate with
unsigned long. So use do_div instead.

The root of problem is carelessly zeroing pointer(in function
__tty_buffer_flush()),
when another thread can use it. It can be cause of "NULL pointer dereference".
Main idea of the patch, this is never release last (struct tty_buffer) in the
active buffer.
Only flush data for ldisc(tty->buf.h

These are mainly small 8250_dw.c changes. The interesting patch is
probable the first one that changes 8250.c so the drivers are able to
deliver their UART's capabilities when they are registering ports.

serial: 8250:
Trivial cleanup. This makes it easier to add different
methods to enumerate the device, for example ACPI 5.0
enumeration.

Modern UARTs are able to provide information about their
capabilities such as FIFO size. This allows the drivers to
deliver this information to 8250.c when they are registering
ports.

including FIFO size. This uses that register to set FIFO

Allow 8250.c to determine the port type for us. This allows
the driver take advantage of FIFO on Designware UARTs that
have it.

Sure! Thanks for the review. As the driver is already in Jiri's tree,
I'll do small incremental patches based on this release.

Allocate regular pages to use as backing for the RX ring and use the
DMA API to sync the caches. This should give a bit better performance
since it allows the CPU to do burst transfers from memory. It is also
a necessary step on the way to reduce the amount of copying done
Depending on datapath, some revisions of GEM need
64bits aligned descriptors. Use dmapool to allocate
these descriptors.
Note that different size between RX and TX rings
leads to the creation of two pools.

Macb Ethernet controller requires a RX buffer of 128 bytes. It is
highly sub-optimal for Gigabit-capable GEM that is able to use
a bigger DMA buffer. Change this constant and associated macros
with data stored in the private structure.
I also kept the result of buffers per page calculation to lower

With the coupled cpuidle driver (but probably also with other drivers),
a CPU loops in a temporary safe state while waiting for other CPUs of its
cluster to be ready to enter the coupled C-state. If an IRQ or a softirq
occurs, the CPU will stay in this internal loop if there is no need
to resched.
The function nohz_kick_needed modifies NOHZ_IDLE flag that is used to update
the nr_busy_cpus of the sched_group.
When the sched_domain are updated (because of the unplug of a CPUs as an
example) a null_domain is attached to CPUs. We have to test
likely(!on_null_domain(cpu) first in order to detect
On my smp platform which is made of 5 cores in 2 clusters,I have the
nr_busy_cpus field of sched_group_power struct that is not null when the
platform is fully idle. The root cause seems to be:
During the boot sequence, some CPUs reach the idle loop and set their
NOHZ_IDLE flag while waiting for ot
The nr_busy_cpus field of the sched_group_power is sometime different from 0
whereas the platform is fully idle. This serie fixes 3 use cases:
- when the SCHED softirq is raised on an idle core for idle load balance but
the platform doesn't go out of the cpuidle state
- when some CPUs enter id
IGEP technology devices are TI OMAP3 SoC based industrial embedded
and computer-on-module boards. This patch-set adds initial device
tree support for these devices.
The device trees allows to boot from an MMC and are working all the

ISEE IGEP COM Module is an TI OMAP3 SoC computer on module.
This patch adds an initial device tree support to boot an

Historically tun supported two modes of operation:
- in default mode, a small number of packets would get queued
at the device, the rest would be queued in qdisc
- in one queue mode, all packets would get queued at the device
This might have made sense up to a point where we made the
queue depth
