X-Git-Tag: v2.6.35-rc1~504^2~7^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=21823259a70b7a2a21eea1d48c25a6f38896dd11;p=pandora-kernel.git sh: Ensure active regions have a backing PMB entry. In the NUMA or memory hot-add case where system memory has been partitioned up, we immediately run in to a situation where the existing PMB entry doesn't cover the new range (primarily as a result of the entry size being shrunk to match the node size early in the initialization). In order to fix this up it's necessary to preload a PMB mapping for the new range prior to activation in order to circumvent reset by MMU. Signed-off-by: Paul Mundt --- Reading git-diff-tree failed
