From b67360db143448be1f6d68835c6d0cc43837667f Mon Sep 17 00:00:00 2001 From: Chris Zankel Date: Thu, 6 Sep 2007 01:38:18 -0700 Subject: [PATCH] [XTENSA] Flush the page-address in update-mmu instead of user-address The TLB entry for the user address doesn't exist at the time we want to flush the caches, so use the page address. Note that processor configurations with cache-aliasing issues are treated separately.
