serial: mrst_max3110: initialize waitqueue earlier

2011-06-23T15:54:10+00:00

The driver went to initialize its waitqueue at the start of the main
processing thread.  However, it is possible that this thread is not
scheduled on a CPU before the write function is called which leads to a
following error:

  BUG: spinlock bad magic on CPU#1, swapper/1
   lock: f5f3ebdc, .magic: 00000000, .owner: /-1, .owner_cpu: 0

Fix this by initializing the waitqueue before the main thread is
created.

mrst_max3110: Change max missing message priority.

2011-06-23T15:54:09+00:00

Change print message to notice instead of error to clean up non critical
messages showing on startup.  The MAX3111 not being present is a normal
path for end user systems.

drivers/tty/serial/pch_uart.c: don't oops if dmi_get_system_info returns NULL

2011-06-16T03:04:02+00:00

If dmi_get_system_info() returns NULL, pch_uart_init_port() will
dereferencea a zero pointer.

This oops was observed on an Atom based board which has no BIOS, but
a bootloder which doesn't provide DMI data.

arch, mm: filter disallowed nodes from arch specific show_mem functions

2011-05-25T15:39:03+00:00

Architectures that implement their own show_mem() function did not pass
the filter argument to show_free_areas() to appropriately avoid emitting
the state of nodes that are disallowed in the current context.  This patch
now passes the filter argument to show_free_areas() so those nodes are now
avoided.

This patch also removes the show_free_areas() wrapper around
__show_free_areas() and converts existing callers to pass an empty filter.

ia64 emits additional information for each node, so skip_free_areas_zone()
must be made global to filter disallowed nodes and it is converted to use
a nid argument rather than a zone for this use case.
