Currently, dumping almost all BTFs specified by id requires using the -B option to pass the base BTF. For most cases the vmlinux BTF sysfs path should work. This patch simplifies dumping by ID usage by attempting to use vmlinux BTF from sysfs, if the first try of loading BTF by ID fails with certain conditions.

Puranjay Mohan says: ==================== arm32, bpf: add support for cpuv4 insns Changes in V2 -> V3 - Added comments at places where there could be confustion. - In the patch for DIV64, fix the if-else case that would never run. - In the same patch use a single instruction to POP caller saved regs. - Add a patch to change maintainership of ARM32 BPF JIT. Changes in V1 -> V2: - Fix coding style issues. - Don't use tmp variable for src in emit_ldsx_r() as it is redundant. - Optimize emit_ldsx_r() when offset can fit in immediate. Add the support for cpuv4 instructions for ARM32 BPF JIT. 64-bit division was not supported earlier so this series adds 64-bit DIV, SDIV, MOD, SMOD instructions as well. This series needs any one of the patches from [1] to disable zero-extension for BPF_MEMSX to support ldsx. The relevant selftests have passed expect ldsx_insn which needs fentry: Tested on BeagleBone Black (ARMv7-A): [root@alarm del]# echo 1 > /proc/sys/net/core/bpf_jit_enable [root@alarm del]#
