https://git.shady.money/linux/atom?h=master2025-03-21T05:57:35Zperf syscalltbl: Remove syscall_table.h2025-03-21T05:57:35ZIan Rogersirogers@google.com2025-03-19T05:07:30Zurn:sha1:af472d3c4454c720300c2e0c4e87c8a7ca2a3012
The definition of "static const char *const syscalltbl[] = {" is done
in a generated syscalls_32.h or syscalls_64.h that is architecture
dependent. In order to include the appropriate file a syscall_table.h
is found via the perf include path and it includes the syscalls_32.h
or syscalls_64.h as appropriate.
To support having multiple syscall tables, one for 32-bit and one for
64-bit, or for different architectures, an include path cannot be
used. Remove syscall_table.h because of this and inline what it does
into syscalltbl.c.
For architectures without a syscall_table.h this will cause a failure
to include either syscalls_32.h or syscalls_64.h rather than a failure
to include syscall_table.h. For architectures that only included one
or other, the behavior matches BITS_PER_LONG as previously done on
architectures supporting both syscalls_32.h and syscalls_64.h.

xtensa uses a syscall table, use that in perf instead of requiring
libaudit.
