x86/asm: Fix UNWIND_HINT_REGS macro for older binutils
Apparently the binutils 2.20 assembler can't handle the '&&' operator in the UNWIND_HINT_REGS macro. Rearrange the macro to do without it. This fixes the following error: arch/x86/entry/entry_64.S: Assembler messages: arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement arch/x86/entry/entry_64.S:521: Error: non-constant expression in ".if" statement Reported-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com> Cc: Andy Lutomirski <luto@kernel.org> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.
