[PATCH V4] mem_event: Add support for MEM_EVENT_REASON_MSR
Add the new MEM_EVENT_REASON_MSR event type. Works similarly to the other register events, except event.gla always contains the MSR address (in addition to event.gfn, which holds the value). MEM_EVENT_REASON_MSR does not honour the HVMPME_onchangeonly bit, as doing so would complicate the hvm_msr_write_intercept() switch-based handling of writes for different MSR addresses, with little added benefit.

[PATCH 0/3] XEN: fix vmx exception mistake
This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length

[PATCH v2 0/4] XEN: fix vmx exception mistake
Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),
