2013-12-12KVM: VMX: shadow VM_(ENTRY|EXIT)_CONTROLS vmcs fieldGleb Natapov
VM_(ENTRY|EXIT)_CONTROLS vmcs fields are read/written on each guest entry but most times it can be avoided since values do not changes. Keep fields copy in memory to avoid unnecessary reads from vmcs. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-12-11KVM: s390: ioeventfd: ignore leftmost bitsDominik Dingel
The diagnose 500 subcode 3 contains the 32 bit subchannel id in bits 32-63 (counting from the left). As for other I/O instructions, bits 0-31 should be ignored and thus not be passed to kvm_io_bus_write_cookie(). This fixes a bug where the guest passed non-zero bits 0-31 which the host tried to interpret, leading to ioeventfd notification failures.

2013-12-11KVM: s390: SIGP START has to report BUSY while stopping a CPUThomas Huth
Just like the RESTART order, the START order also has to report BUSY while a STOP request is pending, to avoid that the START might be ignored due to a race condition between the STOP and the START order.

2013-12-11KVM: s390: Reworked SIGP RESTART orderThomas Huth
When SIGP RESTART detected an illegal CPU address, there is no need to drop to userspace, we can return CC3 to the guest directly instead. Also renamed __sigp_restart() to sigp_check_callable() (since this is a better description of what the function is really doing) and moved a string specific to RESTART to the calling place instead, so that this function gets usable by other SIGP orders, too.

2013-12-11arm/arm64: kvm: Use virt_to_idmap instead of virt_to_phys for idmap mappingsSantosh Shilimkar
KVM initialisation fails on architectures implementing virt_to_idmap() because virt_to_phys() on such architectures won't fetch you the correct idmap page. So update the KVM ARM code to use the virt_to_idmap() to fix the issue. Since the KVM code is shared between arm and arm64, we create kvm_virt_to_phys() and handle the redirection in respective headers.

2013-11-29arm64: Move PTE_PROT_NONE higher upCatalin Marinas
PTE_PROT_NONE means that a pte is present but does not have any read/write attributes. However, setting the memory type like pgprot_writecombine() is allowed and such bits overlap with PTE_PROT_NONE. This causes mmap/munmap issues in drivers that change the vma->vm_pg_prot on PROT_NONE mappings. This patch reverts the PTE_FILE/PTE_PROT_NONE shift in commit 59911ca4325d (ARM64: mm: Move PTE_PROT_NONE bit) and moves PTE_PROT_NONE together with the other software bits.

2013-11-28ALSA: hda - Check leaf nodes to find aamix ampsTakashi Iwai
The current generic parser assumes blindly that the volume and mute amps are found in the aamix node itself. But on some codecs, typically Analog Devices ones, the aamix amps are separately implemented in each leaf node of the aamix node, and the current driver can't establish the correct amp controls. This is a regression compared with the previous static quirks. This patch extends the search for the amps to the leaf nodes for allowing the aamix controls again on such codecs. In this implementation, I didn't code to loop through the whole paths, since usually one depth should suffice, and we can't search too deeply, as it may result in the conflicting control assignments.
