Fix a potention issue caused by kvm_mmu_slot_remove_write_access(). The old behavior don't sync EPT TLB with modified EPT entry, which result in inconsistent content of EPT TLB and EPT table. Signed-off-by: NSheng Yang <sheng.yang@intel.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

kvm_mmu_zap_page() needs slots lock held (rmap_remove->gfn_to_memslot, for example). Since kvm_lock spinlock is held in mmu_shrink(), do a non-blocking down_read_trylock(). Untested. Signed-off-by: NAvi Kivity <avi@qumranet.com>

On suspend the svm_hardware_disable function is called which frees all svm_data variables. On resume they are not re-allocated. This patch removes the deallocation of svm_data from the hardware_disable function to the hardware_unsetup function which is not called on suspend.

While doing some tests with our lcrash implementation I have seen a naming conflict with prefix_info in kvm_host.h vs. addrconf.h To avoid future conflicts lets rename private definitions in asm/kvm_host.h by adding the kvm_s390 prefix.

Some machines do not accept 16EB as guest storage limit. Lets change the default for the guest storage limit to a sane value. We also should set the guest_origin to what userspace thinks it is. This allows guests starting at an address != 0.

This patch #ifdefs the bitmap array for dirty tracking. We don't have dirty tracking on s390 today, and we'd love to use our storage keys to store the dirty information for migration. Therefore, we won't need this array at all, and due to our limited amount of vmalloc space this limits the amount of guests we can run.

Older linux guests (in this case, 2.6.9) can attempt to access the performance counter MSRs without a fixup section, and injecting a GPF kills the guest. Work around by allowing the guest to write those MSRs. Tested by me on RHEL-4 i386 and x86_64 guests, as well as F-9 guests.

The function ept_update_paging_mode_cr0() write to CPU_BASED_VM_EXEC_CONTROL based on vmcs_config.cpu_based_exec_ctrl.

Currently kvmtrace is not portable. This will prevent from copying a trace file from big-endian target to little-endian workstation for analysis. In the patch, kernel outputs metadata containing a magic number to trace log, and changes 64-bit words to be u64 instead of a pair of u32s.

Only abort guest entry if the timer count went from 0->1, since for 1->2 or larger the bit will either be set already or a timer irq will have been injected. Using atomic_inc_and_test() for it also introduces an SMP barrier to the LAPIC version (thought it was unecessary because of timer migration, but guest can be scheduled to a different pCPU between exit and kvm_vcpu_block(), so there is the possibility for a race).

This patch adds all needed structures to coalesce MMIOs. Until an architecture uses it, it is not compiled. Coalesced MMIO introduces two ioctl() to define where are the MMIO zones that can be coalesced: - KVM_REGISTER_COALESCED_MMIO registers a coalesced MMIO zone. It requests one parameter (struct kvm_coalesced_mmio_zone) which defines a memory area where MMIOs can be coalesced until the next switch to user space. The maximum number of MMIO zones is KVM_COALESCED_MMIO_ZONE_MAX. - KVM_UNREGISTER_COALESCED_MMIO cancels all registered zones inside the given bounds (bounds are also given by struct kvm_coalesced_mmio_zone). The userspace client can check kernel coalesced MMIO availability by asking ioctl(KVM_CHECK_EXTENSION) for the KVM_CAP_COALESCED_MMIO capability. The ioctl() call to KVM_CAP_COALESCED_MMIO will return 0 if not supported, or the page offset where will be stored the ring buffer. The page offset depends on the architecture. After an ioctl(KVM_RUN), the first page of the KVM memory mapped points to a kvm_run structure. The offset given by KVM_CAP_COALESCED_MMIO is an offset to the coalesced MMIO ring expressed in PAGE_SIZE relatively to the address of the start of th kvm_run structure. The MMIO ring buffer is defined by the structure kvm_coalesced_mmio_ring.
