Fix to restore BTF if single-stepping causes a page fault and

Usually the BTF flag was restored when the single stepping is done

I found that having the ftrace infrastructure use its own trampoline to
handle recursion and RCU by defaulte unless the ftrace_ops set the
appropriate flags, was an issue that nobody set those flags. But then their

Add a new function allowing to set sustainable OPP from the drivers code.
This is helpful when the device drivers populate the OPP table by
themself.

Mark sustainable OPP frequency based on previously received value from

Mimic the pre-existing ACPI and Device Tree event log behavior by not
creating the binary_bios_measurements file when the EFI TPM event log is
empty.
This fixes the following NULL pointer dereference that can occur when
reading /sys/kernel/security/tpm0/binary_bios_measurements after the
kernel re

That's a question only userspace can answer - but think shell scripts that do

the OPP table by themself (example in patch 4/4).
The patch set should apply on top of next-20201028.

You don't need to do any decompilation -- the descriptor can be obtained

Add opp-sustainable as an additional property in the OPP node to describe
the sustainable performance level of the device. This will help to
estimate the sustainable performance of the whole system.

The IPA hardware manages various resources (e.g. descriptors)
internally to perform its functions. The resources are grouped,
allowing different endpoints to use separate resource pools. This
way one group of endpoints can be configured to operate unaffected

The driver was using subsys_initcall() because in old times deferred

Since probe deferral works fine and specific ordering is discouraged
