In order to have better chance that relevant messages fit into the ring buffer, allocate a dynamic (larger) one in more cases, and make the default allocation size depend on both the number of CPUs and the log level. Also free the static buffer if a dynamic one was obtained. In order for "xm dmesg" to retrieve larger buffers, eliminate pyxc_readconsolering()'s 32k limitation resulting from the use of a statically allocated buffer. Finally, suppress on x86 most per-CPU boot time messages (by default, most of them can be re-enabled with a new command line option "cpuinfo", some others are now only printed more than once when there are inconsistencies between CPUs). This reduces both boot time (namely when a graphical console is in use) and pressure on the console ring and serial transmit buffers. Signed-off-by: Jan Beulich <jbeulich@novell.com>
