This patch series introduces the following:
[1] Support for bpf-to-bpf function calls in the powerpc64 JIT compiler.
[2] Provide a way for resolving function calls because of the way JITed
images are allocated in powerpc64.
[3] Fix to get JITed instruction dumps for multi-function programs from
the bpf system call.
v2:
- Incorporate review comments from Jakub
Sandipan Das (6):
bpf: support 64-bit offsets for bpf function calls
bpf: powerpc64: add JIT support for multi-function programs
bpf: get kernel symbol addresses via syscall
tools: bpf: sync bpf uapi header
tools: bpftool: resolve calls without using imm field
bpf: fix JITed dump for multi-function programs via syscall
