+Subject: SCSI: nsp32: use mdelay instead of large udelay constants
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit b497ceb964a80ebada3b9b3cea4261409039e25a upstream.
+
+ARM cannot handle udelay for more than 2 miliseconds, so we
+should use mdelay instead for those.

+Subject: tracing: Fix fields of struct trace_iterator that are zeroed by mistake
+
+From: Andrew Vagin <avagin@openvz.org>
+
+commit ed5467da0e369e65b247b99eb6403cb79172bcda upstream.
+
+tracing_read_pipe zeros all fields bellow "seq". The declaration contains
+a comment about that, but it doesn't help.
+
+The first field is "snapshot", it's true when current open file is
+snapshot. Looks obvious, that it should not be zeroed.
+
+The second field is "started". It was converted from cpumask_t to
+cpumask_var_t (v2.6.28-4983-g4462344), in other words it was
+converted from cpumask to pointer on cpumask.
+
+Currently the reference on "started" memory is lost after the first read
+from tracing_read_pipe and a proper object will never be freed.
+
+The "started" is never dereferenced for trace_pipe, because trace_pipe
+can't have the TRACE_FILE_ANNOTATE options.
