From: Jeremy Fitzhardinge Date: Fri, 26 Mar 2010 22:37:50 +0000 (-0700) Subject: xen/mmu: inhibit vmap aliases rather than trying to clear them out X-Git-Tag: v2.6.36-rc1~73^2~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d2cb214551de8180542a04ec8c86c0c9412c5124;p=pandora-kernel.git xen/mmu: inhibit vmap aliases rather than trying to clear them out Rather than trying to deal with aliases once they appear, just completely inhibit them. Mostly the removal of aliases was managable, but it comes unstuck in xen_create_contiguous_region() because it gets executed at interrupt time (as a result of dma_alloc_coherent()), which causes all sorts of confusion in the vmap code, as it was never intended to be run in interrupt context. This has the unfortunate side effect of removing all the unmap batching the vmap code so carefully added, but that can't be helped.
