Commit Message

  From: Guo Jin <guoj17@chinatelecom.cn>

When compiling linux configured with CONFIG_64BIT=y
and CONFIG_PARAVIRT_SPINLOCKS=y on x86_64 using LLVM 11.0,
the .spinlock.text is used many times,
But its flags are omitted in subsequent use.

LLVM 11.0 assembler didn't permit to
leave out flags in subsequent uses of the same sections.

So this patch adds the corresponding flags to avoid above error.
