Since commit 7e92e01 ("powerpc: Provide syscall wrapper") landed in v6.1, syscall wrapper is enabled on powerpc. Commit 9474689 ("powerpc: Don't add __powerpc_ prefix to syscall entry points") , that drops the prefix to syscall entry points, also landed in the same release. So, add the missing empty SYS_PREFIX prefix definition for powerpc, to fix some fentry and kprobe selftests. Signed-off-by: Saket Kumar Bhaskar <[email protected]>
On powerpc, a CPU does not necessarily originate from NUMA node 0. This contrasts with architectures like x86, where CPU 0 is not hot-pluggable, making NUMA node 0 a consistently valid node. This discrepancy can lead to failures when creating a map on NUMA node 0, which is initialized by default, if no CPUs are allocated from NUMA node 0. This patch fixes the issue by setting NUMA_NO_NODE (-1) for map creation for this selftest. Fixes: 96eabe7 ("bpf: Allow selecting numa node during map creation") Signed-off-by: Saket Kumar Bhaskar <[email protected]>
