765b8552a2 bootconfig: Check the checksum before removing the bootconfig from initrd
Check the bootconfig's checksum before removing the bootconfig data
from initrd to avoid modifying initrd by mistake.
This will also simplifies the get_boot_config_from_initrd() interface.

6014a23638 bootconfig: Make the bootconfig.o as a normal object file
Since the APIs defined in the bootconfig.o are not individually used,
it is meaningless to build it as library by lib-y. Use obj-y for that.

Most architectures have ftrace related stuff in arch/*/kernel/ftrace.c

In several architectures, there are also additional files containing
'ftrace' as part of the name but with some prefix or suffix.

a7e6b7dcfb tracing: Separate hist state updates from hist registration
hist_register_trigger() handles both new hist registration as well as
existing hist registration through event_command.reg().

Adding a new function, existing_hist_update_only(), that checks and
updates existing histograms and exits after doing so allows the
confusing logic in event_hist_trigger_parse() to be simplified.

b8cc44a4d3 tracing: Remove logic for registering multiple event triggers at a time
Code for registering triggers assumes it's possible to register more
than one trigger at a time.  In fact, it's unimplemented and there
doesn't seem to be a reason to do that.

Remove the n_registered param from event_trigger_register() and fix up
callers.

Doing so simplifies the logic in event_trigger_register to the point
that it just becomes a wrapper calling event_command.reg().

It also removes the problematic call to event_command.unreg() in case
of failure.  A new function, event_trigger_unregister() is also added
for callers to call themselves.

The changes to trace_events_hist.c simply allow compilation; a
separate patch follows which updates the hist triggers to work
correctly with the new changes.

0715372a06 riscv: compat: vdso: Add COMPAT_VDSO base code implementation
There is no vgettimeofday supported in rv32 that makes simple to
generate rv32 vdso code which only needs riscv64 compiler. Other
architectures need change compiler or -m (machine parameter) to
support vdso32 compiling. If rv32 support vgettimeofday (which
cause C compile) in future, we would add CROSS_COMPILE to support
that makes more requirement on compiler enviornment.

306f7cc1e9 uapi: always define F_GETLK64/F_SETLK64/F_SETLKW64 in fcntl.h
The F_GETLK64/F_SETLK64/F_SETLKW64 fcntl opcodes are only implemented
for the 32-bit syscall APIs, but are also needed for compat handling
on 64-bit kernels.

Consolidate them in unistd.h instead of definining the internal compat
definitions in compat.h, which is rather error prone (e.g. parisc
gets the values wrong currently).

Note that before this change they were never visible to userspace due
to the fact that CONFIG_64BIT is only set for kernel builds.

Don't bother to define the symbols empty, just don't use them.
That makes the intent a little more clear.

Remove the unused HAVE_ARCH_STRUCT_FLOCK64 define and merge the
32-bit mips struct flock into the generic one.

Add a new __ARCH_FLOCK_EXTRA_SYSID macro following the style of
__ARCH_FLOCK_PAD to avoid having a separate definition just for
one architecture.

Convert infracfg bindings to DT schema format. Not all drivers
currently implement resets, so #reset-cells is made a required
property only for those that do. Using power-controller in the
example node name makes #power-domain-cells required causing
a dt_binding_check error. To solve this, the node is renamed to

  btf_parse_vmlinux() -> btf_vmlinux_map_ids_init()

It will lookup the btf_type according to the 'map_btf_name' field in

thanks to Jiri's resolve_btfids.

3474b838f4 dt-bindings: Drop undocumented i.MX iomuxc-gpr bindings in examples
The i.MX iomuxc-gpr bindings are undocumented and a mess. Drop their use
from the examples.

The problem with the binding beyond the just random variations is that
the iomuxc-gpr is not a separate block, but registers within the iomuxc
block containing random leftover controls. As a separate DT node, it
creates nodes with overlapping memory addresses.
