Subject: [PATCH] powerpc32/bpf: fix loading fsession func metadata using PPC_LI32
Date: Wed, 8 Apr 2026 01:53:01 -0400 [thread overview]
Message-ID: <20260408055301.232745-1-adubey@linux.ibm.com> (raw)
From: Abhishek Dubey <adubey@linux.ibm.com>
PPC_RAW_LI32 is not a valid macro in the PowerPC BPF JIT. Use PPC_LI32,
which correctly handles immediate loads for large values.
Fixes the build error introduced when adding fsession support on ppc32.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202604040212.jIxEd2DW-lkp@intel.com/
Fixes: 92258b5bf1ec ("powerpc32/bpf: Add fsession support")
Signed-off-by: Abhishek Dubey <adubey@linux.ibm.com>

Need to apply on tp of powerpc -next, as this fixes a build error reported on that branch
