hwmon: (lm93) Add support for LM94

This patch adds basic support for LM94 to the LM93 driver. LM94 specific sensors and features are not supported. Signed-off-by: Guenter Roeck Acked-by: Jean Delvare

perf: Validate cpu early in perf_event_alloc()

2011-01-18T18:34:23Z

Starting from perf_event_alloc()->perf_init_event(), the kernel assumes that event->cpu is either -1 or the valid CPU number. Change perf_event_alloc() to validate this argument early. This also means we can remove the similar check in find_get_context().

perf: Find_get_context: fix the per-cpu-counter check

2011-01-18T18:34:23Z

If task == NULL, find_get_context() should always check that cpu is correct. Afaics, the bug was introduced by 38a81da2 "perf events: Clean up pid passing", but even before that commit "&& cpu != -1" was not exactly right, -ESRCH from find_task_by_vpid() is not accurate.

MIPS: Malta: enable Cirrus FB console

2011-01-18T18:30:29Z

While most users of a physical Malta board are using the serial port as the console, a lot of QEMU users would prefer to interact with a graphical console. Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB.
