linux-toradex.git/drivers/acpi/executer, branch v2.6.27.50 Linux kernel for Apalis and Colibri modules ACPICA: Copy dynamically loaded tables to local buffer 2009-02-12T17:31:13+00:00 Dennis Noordsij dennis.noordsij@helsinki.fi 2008-08-15T01:37:58+00:00 25a4ddbc4f220209081870042e0268dee83afbf9 commit f0e0da8a6cca44396c7a711e308d58084e881617 upstream. Previously, dynamically loaded tables were simply mapped, but on some machines this memory is corrupted after suspend. Now copy the table to a local buffer. For OpRegion case, added checksum verify. Use the table length from the table header, not the region length. For Buffer case, use the table length also. http://bugzilla.kernel.org/show_bug.cgi?id=10734 Signed-off-by: Dennis Noordsij <dennis.noordsij@helsinki.fi> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Thomas Renninger <trenn@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> 
commit f0e0da8a6cca44396c7a711e308d58084e881617 upstream.

Previously, dynamically loaded tables were simply mapped, but on some machines
this memory is corrupted after suspend. Now copy the table to a local buffer.
For OpRegion case, added checksum verify. Use the table length from the table header,
not the region length. For Buffer case, use the table length also.
