[PATCH 5.15 13/89] MIPS: cpu-features: Use boot_cpu_type for CPU type based features

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

[ Upstream commit 5487a7b60695a92cf998350e4beac17144c91fcd ]

Some CPU feature macros were using current_cpu_type to mark feature
availability.

However current_cpu_type will use smp_processor_id, which is prohibited
under preemptable context.

Since those features are all uniform on all CPUs in a SMP system, use
boot_cpu_type instead of current_cpu_type to fix preemptable kernel.
