[PATCH RFT 01/16] perf tools: Create generic syscall table support
Charlie Jenkins

Mon Nov 4 13:06:03 PST 2024
Currently each architecture in perf independently generates syscall
headers. Adapt the work that has gone into unifying syscall header
implementations in the kernel to work with perf tools. Introduce this
framework with riscv at first. riscv previously relied on libaudit, but
with this change, perf tools for riscv no longer needs this external
dependency.
