This is not very likely to happen though, because p9_write_work()

This patch originated from Hiroaki SHIMODA but has been modified
by Intel with some minor cleanups and additional commit log text.

Denys Fedoryshchenko and others reported Tx stalls on e1000e with
BQL enabled.  Issue was root caused to hardware delays. They were
introduced because some of the e1000e hardware with transmit
writeback bursting enabled, waits until the driver does an
explict flush OR there are WTHRESH descriptors to write back.

Sometimes the delays in question were on the order of seconds,
causing visible lag for ssh sessions and unacceptable tx
completion latency, especially for BQL enabled kernels.

To avoid possible Tx stalls, change WTHRESH back to 1.

The current plan is to investigate a method for re-enabling
WTHRESH while not harming BQL, but those patches will be later
for net-next if they work.

vxlan: allow configuring port range

VXLAN bases source UDP port based on flow to help the
receiver to be able to load balance based on outer header flow.

This patch restricts the port range to the normal UDP local
ports, and allows overriding via configuration.

It also uses jhash of Ethernet header when looking at flows
with out know L3 header.

   - new driver for R-Car I2C

11 years agortc: kconfig: fix RTC_INTF defaults connected to RTC_CLASS
Kevin Hilman [Wed, 10 Oct 2012 22:54:06 +0000 (15:54 -0700)]
rtc: kconfig: fix RTC_INTF defaults connected to RTC_CLASS

Commit 6b8029fab641 ("rtc: kconfig: remove unnecessary dependencies")
removed various 'depends on RTC_CLASS' dependencies but also removed a
few 'default RTC_CLASS' statements, which actually changed default
behavior.

This resulted in the various RTC interfaces (sysfs, proc, dev) all being
disabled by default, even when RTC_CLASS is enabled:

   # CONFIG_RTC_INTF_SYSFS is not set
   # CONFIG_RTC_INTF_PROC is not set
   # CONFIG_RTC_INTF_DEV is not set

which is different from previous behavior (all of these where enabled.)

To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.

I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.

  Subsequently, users of the legacy pwm_request() and pwm_free()
  functions can be migrated to the new pwm_get() and pwm_put()
  functions.  Once this has been completed, the legacy API and the
  compatibility code in the core can be removed.

  In addition to the above, these changes also add support for
  configuring the polarity of a PWM signal (currently only supported on
  ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
  Managed functions to obtain and release a PWM device (devm_pwm_get()
  and devm_pwm_put()) have been added and the pwm-backlight driver has
  been updated to use them.  If the PWM subsystem hasn't been enabled,
  dummy functions are provided that allow the subsystem to safely
  compile out.

  Some common checks on input parameters have been moved to the core and
  removed from the drivers.  Finally, a small fix corrects the
  description of the PWM specifier's second cell in the device tree
  representation."

  focused on addressing a few long-standing items within target-core and
  iscsi-target fabric code.

  The highlights include:

   - target: Simplify fabric sense data length handling (roland)

   - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab

  +testing and is clear enough a mechanical change that I think it's
  reasonable to merge for -rc1 code.
