[PATCH 0/7] Emulator exception improvements

[Avi Kivity <avi@redhat.com>]

This boring patchset introduces a struct x86_exception to represent an
exception, and uses it to communicate between the emulator and the rest
of kvm.  The primary benefit is that we can now pass a #GP from kvm into
the emulator, not just #PFs.

I'd like to also fold vcpu->arch.fault into struct x86_exception, but that's
more difficult, so deferred until later.

Avi Kivity (7):
  KVM: x86 emulator: introduce struct x86_exception to communicate
    faults
  KVM: x86 emulator: make emulator memory callbacks return full
    exception
  KVM: x86 emulator: drop dead pf injection in emulate_popf()
  KVM: x86 emulator: tighen up ->read_std() and ->write_std() error
    checks
  KVM: x86 emulator: simplify exception generation
  KVM: Push struct x86_exception info the various gva_to_gpa variants
  KVM: Push struct x86_exception into walk_addr()
