Adding a fix for NMI latency.
Similar fix done in linux: https://lore.kernel.org/patchwork/patch/1062166/
PMCs interrupting at the same time are collapsed into one interrupt. With the current interrupt handler, the majority of samples are missing for one of the event when two such events are used (unhalted_cpu_cycles and retired_intructions). Out of the two, the one which is allocated first reports all the samples while the other one reports negligible numbers.

amd_intr() should only check core pmcs for interrupts since other types of pmcs (L3,DF) cannot generate interrupts.

@emaste : Here's a link to the linux ntb_perf tool which I've used for porting: ntb_perf
Did you mean a delta between linux upstream and my ported version? If yes, find it here D20697
If this is not what you requested, please let me know.

@marius : Don't mean to badger, is there an alternate acceptable way I could go about increasing sdhci performance without increasing the DMA_BLOCK_SIZE. Or if you're planning to add ADMA support, can you maybe let us know when it might become available?

@marius : I know that you must be really busy with the upcoming release. Please review this if possible, I've made the necessary changes that you requested in the last review.

@marius : Are you working on adding ADMA support for sdhci(4) or planning to do so in the near future? If not, I might make an attempt to add ADMA2 support. I was not aware of the MAXPHYS limitation, increasing MAXPHYS to 1MB, I was able to get a further increase in throughput values. I got this idea from this thread (https://lists.freebsd.org/pipermail/freebsd-arch/2010-March/010022.html), where this seems to be a viable option for amd64 platforms.
