Regressions detected on arm, arm64, i386, x86, parisc.

This is on Perf on arm, arm64, i386, x86:

   libbpf.c: In function 'bpf_object__elf_collect':
   libbpf.c:1581:31: error: invalid type argument of '->' (have 'GElf_Shdr' {aka 'Elf64_Shdr'})

This is from PA-RISC with gcc-8, gcc-9, gcc-10, gcc-11:

   /builds/linux/drivers/parisc/sba_iommu.c: In function 'sba_io_pdir_entry':
   /builds/linux/arch/parisc/include/asm/special_insns.h:11:3: error: expected ':' or ')' before 'ASM_EXCEPTIONTABLE_ENTRY'
      ASM_EXCEPTIONTABLE_ENTRY(8b, 9b) \

Bisection of the latter points to "parisc: Fix lpa and lpa_user defines".
