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
