Mark data races to work->wait_index as benign using READ_ONCE and WRITE_ONCE.
These accesses are expected to be racy.

Make sure all the events in each of the sub-buffers that were mapped in a
memory region are valid. This moves the code that walks the buffers for
time-stamp validation out of the CONFIG_RING_BUFFER_VALIDATE_TIME_DELTAS

Add a test against the ring buffer memory range to see if it has valid
data. The ring_buffer_meta structure is given a new field called
"first_buffer" which holds the address of the first sub-buffer. This is
used to both determine if the other fields are valid as

Populate the ring_buffer_meta array. It holds the pointer to the
head_buffer (next to read), the commit_buffer (next to write) the size of
the sub-buffers, number of sub-buffers and an array that keeps track of
the order of the sub-buffers.
This information will

Add a buffer_meta per-cpu file for the trace instance that is mapped to
boot memory. This shows the current meta-data and can be used by user
space tools to record off the current mappings to help reconstruct the
ring buffer after a reboot.

Add two global variables trace_buffer_start and trace_buffer_size. If they
are both set, then a "boot_mapped" instance will be created using the
memory specified by these variables as its ring buffer.
The instance will exist in:

This is for testing purposes only. It hard codes an address that I was
using to store the ring buffer range. How the memory actually gets mapped
will be another project.

In preparation to allowing the trace ring buffer to be allocated in a
range of memory that is persistent across reboots, add
ring_buffer_alloc_range(). It takes a contiguous range of memory and will
split it up evening for the per CPU ring buffers.
If there's not
This is a way to map a ring buffer instance across reboots.
The requirement is that you have a memory region that is not erased.
I tested this on a Debian VM running on qemu on a Debian server,

surprised that it worked on the baremetal
