[ros-dev] [ros-diffs] [ros-arm-bringup] 44856: NMI Support Patch 5: [HAL]: Do correct TLB flushing for systems with global page support. [HAL]: Clean leading whitespace and comments.

[Alex Ionescu]

Why don't you cache this instead of querying it for each TLB flush? Seems stupidly wasteful -- I thought the point was to "make it better"??

Isn't this what HalpGetFeatureBits is for?
