Subject: [PATCH v2 3/7] KVM: x86/mmu: Drop the "p is for pointer" from rmap helpers
Drop the trailing "p" from rmap helpers, i.e. rename functions to simply
be kvm_<action>_rmap(). Declaring that a function takes a pointer is
completely unnecessary and goes against kernel style.
No functional change intended.
