Subject: [PATCH v5 00/16] perf tools: Use generic syscall scripts for all
archs
Standardize the generation of syscall headers around syscall tables.
Previously each architecture independently selected how syscall headers
would be generated, or would not define a way and fallback onto
libaudit. Convert all architectures to use a standard syscall header
generation script and allow each architecture to override the syscall
table to use if they do not use the generic table.
As a result of these changes, no architecture will require libaudit, and
so the fallback case of using libaudit is removed by this series.
Testing:
I have tested that the syscall mappings of id to name generation works
as expected for every architecture, but I have only validated that perf
trace compiles and runs as expected on riscv, arm64, and x86_64.
