acpi-5.9-rc1-2

More ACPI updates for 5.9-rc1

Add new hardware support to the ACPI driver for AMD SoCs, the x86 clk
driver and the Designware i2c driver (changes from Akshu Agrawal and
Pu Wen).

pm-5.9-rc1-3

One more power management update for 5.9-rc1

Modify the intel_pstate driver to allow it to work in the passive
mode with hardware-managed P-states (HWP) enabled.

timers-urgent-2020-08-14

A set oftimekeeping/VDSO updates:

 - Preparatory work to allow S390 to switch over to the generic VDSO
   implementation.

   S390 requires that the VDSO data pointer is handed in to the counter
   read function when time namespace support is enabled. Adding the pointer
   is a NOOP for all other architectures because the compiler is supposed
   to optimize that out when it is unused in the architecture specific
   inline. The change also solved a similar problem for MIPS which
   fortunately has time namespaces not yet enabled.

   S390 needs to update clock related VDSO data independent of the
   timekeeping updates. This was solved so far with yet another sequence
   counter in the S390 implementation. A better solution is to utilize the
   already existing VDSO sequence count for this. The core code now exposes
   helper functions which allow to serialize against the timekeeper code
   and against concurrent readers.

   S390 needs extra data for their clock readout function. The initial
   common VDSO data structure did not provide a way to add that. It now has
   an embedded architecture specific struct embedded which defaults to an
   empty struct.

   Doing this now avoids tree dependencies and conflicts post rc1 and
   allows all other architectures which work on generic VDSO support to
   work from a common upstream base.

 - A trivial comment fix.

timers-core-2020-08-14

A set of posix CPU timer changes which allows to defer the heavy work of
posix CPU timers into task work context. The tick interrupt is reduced to a
quick check which queues the work which is doing the heavy lifting before
returning to user space or going back to guest mode. Moving this out is
deferring the signal delivery slightly but posix CPU timers are inaccurate
by nature as they depend on the tick so there is no real damage. The
relevant test cases all passed.

This lifts the last offender for RT out of the hard interrupt context tick
handler, but it also has the general benefit that the actual heavy work is
accounted to the task/process and not to the tick interrupt itself.

Further optimizations are possible to break long sighand lock hold and
interrupt disabled (on !RT kernels) times when a massive amount of posix
CPU timers (which are unpriviledged) is armed for a task/process.

This is currently only enabled for x86 because the architecture has to
ensure that task work is handled in KVM before entering a guest, which was
just established for x86 with the new common entry/exit code which got
merged post 5.8 and is not the case for other KVM architectures.

irq-urgent-2020-08-14

Two fixes in the core interrupt code which ensure that all error exits
unlock the descriptor lock.
