- kbuild found missing define of MCOUNT_INSN_SIZE for various build configs
- Initialize variable to zero as gcc thinks it is used undefined
(it really isn't but the code is subtle enough that this doesn't hurt)
- Convert from do_div() to div64_ull() to prevent potential divide by zero
- Unregister a trace point on error path in sched_wakeup tracer
- Use signed offset for archs that can have stext not be first
- A simple indentation fix (whitespace error)

* tag 'trace-v5.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Fix indentation issue
kernel/trace: Fix do not unregister tracepoints when register sched_migrate_task fail
tracing: Change offset type to s32 in preempt/irq tracepoints
ftrace: Avoid potential division by zero in function profiler
tracing: Have stack tracer compile when MCOUNT_INSN_SIZE is not defined
tracing: Define MCOUNT_INSN_SIZE when not defined without direct calls
tracing: Initialize val to zero in parse_entry of inject code
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
