From: Alexey Dobriyan Date: Mon, 5 Feb 2024 09:39:30 +0000 (+0300) Subject: smp: make __smp_processor_id() 0-argument macro X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=022b973a3de9b45148e4ae2da1480ec9e61e74a2;p=linux.git smp: make __smp_processor_id() 0-argument macro smp_processor_id family of macros never accepted any arguments. #define __smp_processor_id(x) works by accident (see C99 6.10.3 ยง4). __smp_processor_id() gets 1 (empty) argument and passes it down to raw_smp_processor_id() which doesn't accept arguments.
