Re: [PATCH 3/3] KVM: use vcalloc/__vcalloc for very large allocations

Allocations whose size is related to the memslot size can be arbitrarily large. Do not use kvzalloc/kvcalloc, as those are limited to "not crazy" sizes that fit in 32 bits. Now that it is available, they can use either vcalloc or __vcalloc, the latter if accounting is required.
