Subject: SMP race condition on startup with patch clarification
Date: Tue, 30 Apr 2002 07:26:57 -0700 (PDT) [thread overview]
Message-ID: <20020430142657.17875.qmail@web10407.mail.yahoo.com> (raw)
This could also be done by
leaving init_idle as an init function
& doing a check in all
the cpu_idle functions in arch/process.c
#ifdef CONFIG_SMP
if(smp_processor_id()!=0)
#endif
init_idle();
This would save it attempting to
call the init_idle function
the second time on the boot processor after
it has been freed by free_initmem & avoid the crash.
This patch however would be much bigger
& affect all the arches & probably would
upset more people.
