We call arm64_apply_bp_hardening() from post_ttbr_update_workaround,
which has the unexpected consequence of being triggered on every
exception return to userspace when ARM64_SW_TTBR0_PAN is selected,
even if no context switch actually occured.
This is a bit suboptimal, and it would be more logical to only
invalidate the branch predictor when we actually switch to
a different mm.
In order to solve this, move the call to arm64_apply_bp_hardening()
into check_and_switch_context(), where we're guaranteed to pick
a different mm context.

Kryo cores are exposed to two vulnerabilities due to subroutine return
(called LINK-STACK) and branch target predictors.
These two issues can be mitigated through software workarounds.
Kernel:
- Apply LINK-STACK mitigation which is to issue 16 nested BL instructions
on process context switch 'cpu_do_switch_mm()' where ASID changes.
- Apply psci based branch predictor invalidation.
use the kryo core detection routine (based on MIDR) from the

Aliasing attacks against CPU branch predictors can allow the attacks to
redirect speculative control flow on some CPUs and potentially divulge
information from one context to another.
This patch adds initial skeleton code behind a new Kconfig option to
enable implementation-specific mitigations against these attacks for
CPUs that are affected.
