There is no more direct user of this macro; it is only used by
cc-ifversion.
Calling this macro is not efficient since it invokes the compiler to
get the compiler version. CONFIG_GCC_VERSION is already calculated in
the Kconfig stage, so Makefile can reuse it.
Here is a note about the slight difference between cc-version and
CONFIG_GCC_VERSION:
When using Clang, cc-version is evaluated to '0402' because Clang
defines __GNUC__ and __GNUC__MINOR__, and looks like GCC 4.2 in the
version point of view. On the other hand, CONFIG_GCC_VERSION=0
when $(CC) is clang.
There are currently two users of cc-ifversion:
arch/mips/loongson64/Platform
arch/powerpc/Makefile
They are not affected by this change.
The format of cc-version is <major><minor>, while CONFIG_GCC_VERSION
<major><minor><patch>. I adjusted cc-ifversion for the difference of
the number of digits.

earth-pt1 driver was decomposed/restructured by the commit b732539efd
("media: dvb: earth-pt1: decompose pt1 driver into sub drivers"),
but it introduced a problem regarding concurrent streaming:
Opening a new terrestial stream stops the reception of an existing,
already-opened satellite stream.
The demod IC in earth-pt1 boards contains 2 pairs of terr. and sat. blocks,
supporting 4 concurrent demodulations, and the above problem was because
the config of a terr. block contained whole reset/init of the pair blocks,
thus each open() of a terrestrial frontend wrongly cleared the config of
its peer satellite block of the demod.
This whole/pair reset should be executed earlier and not on each open().

This patch adds support for "atomic" API. This behavior differs with
legacy APIs a little.
Legacy APIs:
The PWMCNT register will be updated in rcar_pwm_config() even if
the PWM state is disabled.
Atomic API:
The PWMCNT register will be updated in rcar_pwm_apply() only if
the PWM state is enabled. Otherwize, if a PWM runs with 30% duty
cycles and the pwm_apply_state() is called with state->enabled = 0,
->duty_cycle = 60 and ->period = 100, this is possible to output
a 60% duty cycle.

mlxsw: minimal: Add ethtool and resource query support
Vadim says:
The minimal driver is chip independent and uses I2C bus for chip access.
Its purpose is to support chassis management on systems equipped with
Mellanox switch ASICs. For example, from a BMC (Board Management
Controller) device.
Patches #1-#3 add ethtool support to the minimal driver so that QSFP/SFP
module info could be retrieved by the driver. This is done by exposing a
dummy netdev for each front panel port and implementing the required
ethtool operations.
Patches #4-#8 add resource query support. This allows the driver to
query the firmware about values of certain resources (e.g., maximum
number of ports). It is required on systems where the maximum number of
ports is larger than the hard coded default (64).

Today, tls_sw_recvmsg is capable of using asynchronous mode to handle
application data TLS records. Moreover, it assumes that if the cipher
can be handled asynchronously, then all packets will be processed
asynchronously.
However, this assumption is not always true. Specifically, for AES-GCM
in TLS1.2, it causes data corruption, and breaks user applications.
This patch fixes this problem by separating the async capability from
the decryption operation result.
