x86: clean up symbol aliasing
Now that we have SYM_FUNC_ALIAS() and SYM_FUNC_ALIAS_WEAK(), use those to simplify the definition of function aliases across arch/x86. For clarity, where there are multiple annotations such as EXPORT_SYMBOL(), I've tried to keep annotations grouped by symbol. For example, where a function has a name and an alias which are both exported, this is organised as: SYM_FUNC_START(func) ... asm insns ... SYM_FUNC_END(func) EXPORT_SYMBOL(func) SYM_FUNC_ALIAS(alias, func) EXPORT_SYMBOL(alias) Where there are only aliases and no exports or other annotations, I have not bothered with line spacing, e.g. SYM_FUNC_START(func) ... asm insns ... SYM_FUNC_END(func) SYM_FUNC_ALIAS(alias, func) The tools/perf/ copies of memset_64.S and memset_64.S are updated likewise to avoid the build system complaining these are mismatched: | Warning: Kernel ABI header at 'tools/arch/x86/lib/memcpy_64.S' differs from latest version at 'arch/x86/lib/memcpy_64.S' | diff -u tools/arch/x86/lib/memcpy_64.S arch/x86/lib/memcpy_64.S | Warning: Kernel ABI header at 'tools/arch/x86/lib/memset_64.S' differs from latest version at 'arch/x86/lib/memset_64.S' | diff -u tools/arch/x86/lib/memset_64.S arch/x86/lib/memset_64.S There should be no functional change as a result of this patch.
