Subject: [PATCH v3 0/8] bpf powerpc: Add BPF_PROBE_MEM support in powerpc JIT compiler
Date: Tue, 21 Sep 2021 18:59:35 +0530	[thread overview]
Message-ID: <20210921132943.489732-1-hbathini@linux.ibm.com> (raw)

Patch #1 & #2 are simple cleanup patches. Patch #3 refactors JIT
compiler code with the aim to simplify adding BPF_PROBE_MEM support.
Patch #4 introduces PPC_RAW_BRANCH() macro instead of open coding
branch instruction. Patch #5 & #7 add BPF_PROBE_MEM support for PPC64
& PPC32 JIT compilers respectively. Patch #6 & #8 handle bad userspace
pointers for PPC64 & PPC32 cases respectively.

Changes in v3:
* Addressed all the review comments from Christophe.

Hari Bathini (4):
  bpf powerpc: refactor JIT compiler code
  powerpc/ppc-opcode: introduce PPC_RAW_BRANCH() macro
  bpf ppc32: Add BPF_PROBE_MEM support for JIT
  bpf ppc32: Access only if addr is kernel address

Ravi Bangoria (4):
  bpf powerpc: Remove unused SEEN_STACK
  bpf powerpc: Remove extra_pass from bpf_jit_build_body()
  bpf ppc64: Add BPF_PROBE_MEM support for JIT
  bpf ppc64: Access only if addr is kernel address
