commit c5c53f58e89922f28ad97cf350ee8756005266e1 Author: Aaron Durbin adurbin@chromium.org Date: Fri Mar 22 22:09:46 2013 -0500
resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]
The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes on a resource provided hints to the MTRR algorithm. The IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable space for the resource. The IORESOURCE_IGNORE_MTRR directed the MTRR algorithm to ignore this resource as it was used reserving RAM space.
Now that the optimizing MTRR algorithm is in place there isn't a need for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the MTRR code merging resources of the same cacheable type. The users of the IORESOURCE_UMA_FB will find that the default MTRR type calculation mean there isn't a need for this flag any more.
