Pls., consider applying this patch series.
It contains the following changes:
- Adds two new macros DEFINE_EARLY_PER_CPU_READ_MOSTLY() and
- Adds "read-mostly" qualifier to the following variables in smp.h:
As long as all the variables above are only written during the initialization,
this change is meant to prevent the false sharing and improve the
performance on large multiprocessor systems.
