      KVM: ia64: Code cleanup · 22ccb142
      由 Xiantao Zhang 提交于 
      Remove some unnecessary blank lines to accord with Kernel's coding style.
Also remove vcpu_get_itir_on_fault due to no reference to it.

      KVM: ia64: stack get/restore patch · e9a999fe
      由 Jes Sorensen 提交于 
      Implement KVM_IA64_VCPU_[GS]ET_STACK ioctl calls. This is required
for live migrations.

Patch is based on previous implementation that was part of old
GET/SET_REGS ioctl calls.

      KVM: New guest debug interface · d0bfb940
      由 Jan Kiszka 提交于 
      This rips out the support for KVM_DEBUG_GUEST and introduces a new IOCTL
instead: KVM_SET_GUEST_DEBUG. The IOCTL payload consists of a generic
part, controlling the "main switch" and the single-step feature. The
arch specific part adds an x86 interface for intercepting both types of
debug exceptions separately and re-injecting them when the host was not
interested. Moveover, the foundation for guest debugging via debug
registers is layed.

To signal breakpoint events properly back to userland, an arch-specific
data block is now returned along KVM_EXIT_DEBUG. For x86, the arch block
contains the PC, the debug exception, and relevant debug registers to
tell debug events properly apart.

The availability of this new interface is signaled by
KVM_CAP_SET_GUEST_DEBUG. Empty stubs for not yet supported archs are
provided.

Note that both SVM and VTX are supported, but only the latter was tested
yet. Based on the experience with all those VTX corner case, I would be
fairly surprised if SVM will work out of the box.

      KVM: ia64: Fix irq disabling leak in error handling code · cab7a1ee
      由 Julia Lawall 提交于 
      There is a call to local_irq_restore in the normal exit case, so it would
seem that there should be one on an error return as well.

The semantic patch that finds this problem is as follows:

expression l;
