Williamsjohn.williams@petalogix.com2011-05-24T08:59:45Zurn:sha1:95ce618f85a86a7383c1a3e39278be3de84b1b99
The current cpuinfo output for the cache policy has no leading tag:, making
it difficult to parse. Add a leaning "Dcache-policy:" tag to this field.

microblaze: Unprivileged stream instruction awareness2011-07-25T07:13:42ZJohn A. Williamsjohn.williams@petalogix.com2011-05-24T08:57:11Zurn:sha1:8904976e8ca45be3ec75acc71f5d855ef671a079
Add cpuinfo support for the new MicroBlaze option permitting userspace
(unprivileged) access to the streaming instructions (FSL / AXI-stream).
Emit a noisy warning at bootup if this is enabled, because bad user code
can potentially lockup the CPU.

Larger pages can improve performance on some workloads.
Based on PowerPC code.
