00cb24bec0 ARM: dts: Configure also interconnect clocks for am4 system timer
We now manage clocksource and clockevent clocks directly with
timer-ti-dm-systimer. In order to use genpd with prm_omap,
GENPD_FLAG_PM_CLK and simple-pm-bus, we need to keep the system
timer related interconnect clocks enabled until clocksource suspend
is done.

  - Simplify the scheduling of event groups to make the code more robust and

  - Prevent event multiplexing and rotation for exclusive event groups
 
  - Correct the perf event attribute exclusive semantics to take pinned

  - Make the anythread filtering conditional for Intel's generic PMU

53bf2776e3 ARM: dts: exynos: revert "add input clock to CMU in Exynos4412 Odroid"
This reverts commit eaf2d2f6895d676dda6c95a652b58594f2887720.

The commit eaf2d2f6895d ("ARM: dts: exynos: add input clock to CMU in
Exynos4412 Odroid") breaks probing of usb3503 USB hub on Odroid U3.

It changes the order of clock drivers probe: the clkout (Exynos PMU)
driver is probed before the main clk-exynos4 driver.  The clkout driver
on Exynos4412 depends on clk-exynos4 but it does not support deferred
probe, therefore this dependency and changed probe order causes probe
failure.

The usb3503 USB hub on Odroid U3 on the other hand requires clkout
clock.  This can be seen in logs:

    [    5.007442] usb3503 0-0008: unable to request refclk (-517)

86cd97ec4b crypto: arm/chacha-neon - optimize for non-block size multiples
The current NEON based ChaCha implementation for ARM is optimized for
multiples of 4x the ChaCha block size (64 bytes). This makes sense for
block encryption, but given that ChaCha is also often used in the
context of networking, it makes sense to consider arbitrary length
inputs as well.

For example, WireGuard typically uses 1420 byte packets, and performing
ChaCha encryption involves 5 invocations of chacha_4block_xor_neon()
and 3 invocations of chacha_block_xor_neon(), where the last one also
involves a memcpy() using a buffer on the stack to process the final
chunk of 1420 % 64 == 12 bytes.

Let's optimize for this case as well, by letting chacha_4block_xor_neon()
deal with any input size between 64 and 256 bytes, using NEON permutation
instructions and overlapping loads and stores. This way, the 140 byte
tail of a 1420 byte input buffer can simply be processed in one go.

This results in the following performance improvements for 1420 byte
blocks, without significant impact on power-of-2 input sizes. (Note
that Raspberry Pi is widely used in combination with a 32-bit kernel,
even though the core is 64-bit capable)

   Cortex-A8  (BeagleBone)       :   7%
   Cortex-A15 (Calxeda Midway)   :  21%
   Cortex-A53 (Raspberry Pi 3)   :   3%
   Cortex-A72 (Raspberry Pi 4)   :  19%

735e8d93dc ARM: 9022/1: Change arch/arm/lib/mem*.S to use WEAK instead of .weak
Commit d6d51a96c7d6 ("ARM: 9014/2: Replace string mem* functions for
KASan") add .weak directives to memcpy/memmove/memset to avoid collision
with KASAN interceptors.

This does not work with LLVM's integrated assembler (the assembly snippet
`.weak memcpy ... .globl memcpy` produces a STB_GLOBAL memcpy while GNU as
produces a STB_WEAK memcpy). LLVM 12 (since https://reviews.llvm.org/D90108)
will error on such an overridden symbol binding.

Use the appropriate WEAK macro instead.
