Subject: [GIT PULL] KVM changes for 3.18
Linus,
The following changes since commit ab3f285f227fec62868037e9b1b1fd18294a83b8:
KVM: s390/mm: try a cow on read only pages for key ops (2014-08-25 14:35:28 +0200)
are available in the git repository at:
git://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus
for you to fetch changes up to f439ed27f8b8b90d243ae15acb193d37f96eebe0:
kvm: do not handle APIC access page if in-kernel irqchip is not in use (2014-10-02 19:26:11 +0200)
----------------------------------------------------------------
Fixes and features for 3.18.
Apart from the usual cleanups, here is the summary of new features:
- s390 moves closer towards host large page support
- PowerPC has improved support for debugging (both inside the guest and
via gdbstub) and support for e6500 processors
- ARM/ARM64 support read-only memory (which is necessary to put firmware
in emulated NOR flash)
- x86 has the usual emulator fixes and nested virtualization improvements
(including improved Windows support on Intel and Jailhouse hypervisor
support on AMD), adaptive PLE which helps overcommitting of huge guests.
Also included are some patches that make KVM more friendly to memory
hot-unplug, and fixes for rare caching bugs.
Two patches have trivial mm/ parts that were acked by Rik and Andrew.
Note: I will soon switch to a subkey for signing purposes. To verify
future signed pull requests from me, please update my key with
"gpg --recv-keys 9B4D86F2". You should see 3 new subkeys---the
one for signing will be a 2048-bit RSA key, 4E6B09D7.
