arm64: barriers: introduce nops and __nops macros for NOP sequences NOP sequences tend to get used for padding out alternative sections and uarch-specific pipeline flushes in errata workarounds. This patch adds macros for generating these sequences as both inline asm blocks, but also as strings suitable for embedding in other asm blocks directly.
