[PATCH 3/5] KVM: arm64: Rename __vcpu_sys_reg -> vcpu_sys_reg
Alexandru Elisei

Wed Jul 14 02:55:59 PDT 2021
There are two macros to access a specific system register from a known
kvm_cpu_context: __ctxt_sys_reg(), which returns a pointer to the register,
and ctxt_sys_reg(), which deferences the pointer returned by
__ctxt_sys_reg().
__vcpu_sys_reg() serves a similar purpose, with the difference being that
it takes a struct kvm_vcpu as a parameter. __vcpu_sys_reg(), although it
looks like __ctxt_sys_reg(), it dereferences the pointer to the register,
like ctxt_sys_reg() does, and indeed it is defined as an abstraction over
ctxt_sys_reg().
Let's remove this naming inconsistency by renaming __vcpu_sys_reg() to
vcpu_sys_reg(), to make it clear it behaves like ctxt_sys_reg(), and not
like __ctxt_sys_reg().
