Merge patch series "riscv: ftrace: Miscellaneous ftrace improvements"

Björn Töpel <bjorn@kernel.org> says:

This series includes a three ftrace improvements for RISC-V:

1. Do not require to run recordmcount at build time (patch 1)
2. Simplification of the function graph functionality (patch 2)
3. Enable DYNAMIC_FTRACE_WITH_DIRECT_CALLS (patch 3 and 4)

The series has been tested on Qemu/rv64 virt/Debian sid with the
following test configs:
  CONFIG_FTRACE_SELFTEST=y
  CONFIG_FTRACE_STARTUP_TEST=y
  CONFIG_SAMPLE_FTRACE_DIRECT=m
  CONFIG_SAMPLE_FTRACE_DIRECT_MULTI=m
  CONFIG_SAMPLE_FTRACE_OPS=m

All tests pass.

* b4-shazam-merge:
  samples: ftrace: Add RISC-V support for SAMPLE_FTRACE_DIRECT[_MULTI]
  riscv: ftrace: Add DYNAMIC_FTRACE_WITH_DIRECT_CALLS support
  riscv: ftrace: Make function graph use ftrace directly
  riscv: select FTRACE_MCOUNT_USE_PATCHABLE_FUNCTION_ENTRY
