KVM: Allow cross page reads and writes from cached translations.
commit 8f964525a121f2ff2df948dac908dcc65be21b5b upstream.
This patch adds support for kvm_gfn_to_hva_cache_init functions for
reads and writes that will cross a page. If the range falls within
the same memslot, then this will be a fast operation. If the range
is split between two memslots, then the slower kvm_read_guest and
kvm_write_guest are used.
Tested: Test against kvm_clock unit tests.

[bwh: Backported to 3.2:
- Drop change in lapic.c
- Keep using __gfn_to_memslot() in kvm_gfn_to_hva_cache_init()]
