    arm64: fix !CONFIG_COMPAT build failures · ff268ff7
    Mark Salter authored
    Recent arm64 builds using CONFIG_ARM64_64K_PAGES are failing with:
    
      arch/arm64/kernel/perf_regs.c: In function ‘perf_reg_abi’:
      arch/arm64/kernel/perf_regs.c:41:2: error: implicit declaration of function ‘is_compat_thread’
    
      arch/arm64/kernel/perf_event.c:1398:2: error: unknown type name ‘compat_uptr_t’
    
    This is due to some recent arm64 perf commits with compat support:
    
      commit 23c7d70d:
        ARM64: perf: add support for frame pointer unwinding in compat mode
    
      commit 2ee0d7fd:
        ARM64: perf: add support for perf registers API
    
    Those patches make the arm64 kernel unbuildable if CONFIG_COMPAT is not
    defined and CONFIG_ARM64_64K_PAGES depends on !CONFIG_COMPAT. This patch
    allows the arm64 kernel to build with and without CONFIG_COMPAT.
