-Subject: ARM: add PROC_VTABLE and PROC_TABLE macros
-
-[ Upstream commit e209950fdd065d2cc46e6338e47e52841b830cba ]
-
-Allow the way we access members of the processor vtable to be changed
-at compile time. We will need to move to per-CPU vtables to fix the
-Spectre variant 2 issues on big.Little systems.
-
-However, we have a couple of calls that do not need the vtable
-treatment, and indeed cause a kernel warning due to the (later) use
-of smp_processor_id(), so also introduce the PROC_TABLE macro for
-these which always use CPU 0's function pointers.
