KVM: s390/mm: remove outdated gmap data structures (2014-08-26 10:09:03 +0200)
NOTE:
There is one non-s390 change in patch " KVM: clarify the idea of kvm_dirty_regs"
to Documentation/virtual/kvm/api.txt but this is actually an interface that is
currently only used for s390. This update better describes the way it was intended
(and implemented) some years ago.
----------------------------------------------------------------
KVM: s390: Fixes and features for 3.18 part 1
1. The usual cleanups: get rid of duplicate code, use defines, factor
out the sync_reg handling, additional docs for sync_regs, better
error handling on interrupt injection
2. We use KVM_REQ_TLB_FLUSH instead of open coding tlb flushes
3. Additional registers for kvm_run sync regs. This is usually not
needed in the fast path due to eventfd/irqfd, but kvm stat claims
that we reduced the overhead of console output by ~50% on my system
4. A rework of the gmap infrastructure. This is the 2nd step towards
host large page support (after getting rid of the storage key
dependency). We introduces two radix trees to store the guest-to-host
and host-to-guest translations. This gets us rid of most of
the page-table walks in the gmap code. Only one in __gmap_link is left,
this one is required to link the shadow page table to the process page
table. Finally this contains the plumbing to support gmap page tables
with less than 5 levels.
