Andrew Honig c471da1e3f KVM: Allow cross page reads and writes from cached translations.
commit 8f964525a1 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
