Tests showed, that under certain conditions, the summary number of jiffies
spent on softirq/idle, which are counted by system statistics can be even
below 10% of expected value, resulting in false load presentation.
The issue was observed on the quad-core Marvell Armada 8k SoC, whose two
10G ports were bound into L2 bridge. Load was controlled by bidirectional
UDP traffic, produced by a packet generator. Under such condition,
the dominant load is softirq. With 100% single CPU occupation or without
any activity (all CPUs 100% idle), total number of jiffies is 10000 (2500
per each core) in 10s interval. Also with other kind of load this was
true.
However below a saturation threshold it was observed, that with CPU which
was occupied almost by softirqs only, the statistic were awkward. See
the mpstat output:
CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle
all 0.00 0.00 0.13 0.00 0.00 0.55 0.00 0.00 0.00 99.32
0 0.00 0.00 0.00 0.00 0.00 23.08 0.00 0.00 0.00 76.92
1 0.00 0.00 0.40 0.00 0.00 0.00 0.00 0.00 0.00 99.60
2 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00
3 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00
Above would mean basically no total load, debug CPU0 occupied in 25%.
Raw statistics, printed every 10s from /proc/stat unveiled a root
cause - summary idle/softirq jiffies on loaded CPU were below 200,
i.e. over 90% samples lost. All problems were gone after enabling
fine granulity IRQ time accounting.
This patch fixes possible wrong statistics processing by enabling
CONFIG_IRQ_TIME_ACCOUNTING for arm64 platfroms, which is by
default done on other architectures, e.g. x86 and arm. Tests
showed no noticeable performance penalty, nor stability impact.

The hardware spinlock drivers now depend on HWSPINLOCK (instead of
selecting it), so we need to explicitly enable it after commit
35fc8a07d7 ("Make HWSPINLOCK a menuconfig to ease disabling")
Without HWSPINLOCK, various drivers are left with unsatisfied
dependencies and Qcom boards using shared memory based communication
to request regulators are failing to boot and mount rootfs.
Fix this by explicitly enabling HWSPINLOCK in defconfig.

Changes to platform code for 64-bit ARM platforms.
Andreas Färber adds two new platforms with initial code: Realtek RTD1295
and Action Semi S900. Both are fairly similar chips, used mainly in
set-top-boxes, but with other possible applications, and additional
members in the respective product families that could be added in the
future. The code here is fairly minimal, as all the interesting parts
are in device drivers and dts files.
The Broadcom Vulcan platform gets dropped, as no products ever became
available, and Cavium integrated the platform under a new name.
Among some other defconfig changes, Timur Tabi enables a number of
options that are typically required for server platforms.

Enable some very core config options used on 64bit Rockchip socs.
As built-in driver enable the Rockchip spi driver as well as the
cros-ec-spi and cros-ec keyboard driver, as this may be helpful
in case an initrd does not work as expected and drops the user
into a shell. Another built-in is the fan53555 regulator driver,
as it and its register-compatible cousins Silergy syr827 and syr828
are often used on Rockchip socs as cpu-supply next to regular pmic.
The rest can be enabled as modules and contains the pcie host
controller and its phy, the sucessive approximation adc (saradc)
that gets often used for additional buttons on Rockchip boards
as well as the adc-keys Keyboard driver for these keys.
The cros-ec-pwm also can be a module, as it is normally only used to
drive display backlights as well as the Rockchip thermal controller
that allows to read the cpu and gpu temperatures and affect frequency
scaling if necessary.

The PMULL based CRC32 implementation already contains code based on the
separate, optional CRC32 instructions to fallback to when operating on
small quantities of data. We can expose these routines directly on systems
that lack the 64x64 PMULL instructions but do implement the CRC32 ones,
which makes the driver that is based solely on those CRC32 instructions
redundant. So remove it.
Note that this aligns arm64 with ARM, whose accelerated CRC32 driver
also combines the CRC32 extension based and the PMULL based versions.

The default value of 17 for CONFIG_LOG_BUF_SHIFT is much more suitable
than 14. The latter easily leads to lost kernel messages on systems with
