Cover letter [PATCH 0/2] mce-inject: extend mce-inject for support threshold interrupt event injection on ADM platform

The work based on Boris's ras-for-3.19 branch.
https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git -b ras-for-3.19

Until now, `mce-inject' is unable to inject threshold interrupt event on AMD platform. That's because both Threshold Interrupt and POLL have a separate event handler. amd_threshold_interrupt() is used for handling Threshold Interrupt event. And machine_check_poll() has been used for polling other events, such as `deferred' error. The main items of this work include:

* apply MCE MSR wrappers to AMD-specific threshold interrupt handler for supporting mce-inject
* introduces a new flag MCJ_INTERRUPT that is used to separate CMCI/Threshold Interrupt and POLL in mce-inject.

Note that Linux machine check injector tool - mce-inject should be also updated for accommodating the above changes in kernel-space.
* [PATCH] separate CMCI/Threshold Interrupt and POLL in mce-inject
