From: Anton Blanchard Date: Tue, 24 Aug 2010 14:23:44 +0000 (+0000) Subject: powerpc/kdump: Override crash_free_reserved_phys_range to avoid freeing RTAS X-Git-Tag: v2.6.38-rc1~405^2~50 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d72e063bb32c06c6c1cec14f6857b7c37ba62d7a;p=pandora-kernel.git powerpc/kdump: Override crash_free_reserved_phys_range to avoid freeing RTAS The crashkernel region will almost always overlap RTAS. If we free the crashkernel region via "echo 0 > /sys/kernel/kexec_crash_size" then we will free RTAS and the machine will crash in confusing and exciting ways. Override crash_free_reserved_phys_range and check for overlap with RTAS. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
