Makefile: Exclude false positive warning options for Clang 

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I9SOCR



---------------------------

Fix three false positive warning options for Bisheng Clang.

Exclude -Walign-mismatch for:
  block/blk-mq.c:767:51: warning: passing 8-byte aligned argument to 32-byte
  aligned parameter 2 of 'smp_call_function_single_async' may result in an
  unaligned pointer access [-Walign-mismatch]
  smp_call_function_single_async(rq->mq_ctx->cpu, &rq->csd);
  ^

Exclude -Wbitwise-instead-of-logical for:
  fs/namei.c:2053:13: warning: use of bitwise '|' with boolean operands
  [-Wbitwise-instead-of-logical]
  } while (!(has_zero(a, &adata, &constants) | has_zero(b, &bdata,...
  ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  ||
  fs/namei.c:2053:13: note: cast one or both operands to int to silence this
  warning

Exclude -Wmacro-redefined for:
  ./arch/arm64/include/asm/elf.h:218:9: warning: 'COMPAT_ARCH_DLINFO' macro
  redefined [-Wmacro-redefined]
  #define COMPAT_ARCH_DLINFO                                              \
          ^
  arch/arm64/kernel/binfmt_elf32.c:22:9: note: previous definition is here
  #define COMPAT_ARCH_DLINFO
