selftests/bpf: fix lots of silly mistakes pointed out by compiler Once we enable -Wall for BPF sources, compiler will complain about lots of unused variables, variables that are set but never read, etc. Fix all these issues first before enabling -Wall in Makefile.

selftests/bpf: Fix tests to use arch-dependent syscall entry points Some of the tests are using x86_64 ABI-specific syscall entry points (such as __x64_sys_nanosleep and __x64_sys_getpgid). Update them to use architecture-dependent syscall entry names. Also update fexit_sleep test to not use BPF_PROG() so that it is clear that the syscall parameters aren't being accessed in the bpf prog. Note that none of the bpf progs in these tests are actually accessing any of the syscall parameters. The only exception is perfbuf_bench, which passes on the bpf prog context into bpf_perf_event_output() as a pointer to pt_regs, but that looks to be mostly ignored. Signed-off-by: Naveen N.

selftests/bpf: ringbuf: Use runtime page size Replace hardcoded 4096 with runtime value in the userspace part of the test and set bpf table sizes dynamically according to the value. Do not switch to ASSERT macros, keep CHECK, for consistency with the rest of the test. Can be a separate cleanup patch.
