Hi Linus,
Please pull this tiny overflow helper addition for v5.8-rc2. During the

at vop full platform this is swapped, and this is different from vop

This patch adds support for indirect access to the registers via parent

The use case is, the spi master is a sub device of a Multifunction

Hi!
I was consistently hitting a VM_BUG_ON_PAGE() in split_huge_page_to_list()
when running vanilla 5.8-rc1 on my desktop. It was happening on every boot
during the system start. I haven't seen this issue on 5.7.
It looks like split_huge_page() expects the page to be locked,
but it hasn't been

When using trace-cmd on 5.6-rt for the function graph tracer, the output was
corrupted. It gave output like this:
funcgraph_entry: func=0x depth=38982
funcgraph_entry: func=0x1 depth=16044
funcgraph_exit:func=0x
Here's a list fixes and clean ups for tracing.
