sparc: Make '-p' boot option meaningful again. 2011-09-21T19:48:06+00:00 David S.

This is necessary to try and see crash messages that occur between the registry of the VT console and the probing of the first framebuffer or serial console. During this time no console messages are emitted because the VT console registry (even if no backend is registered to it) removes the early console if CON_BOOT is set. Signed-off-by: David S.

arch, mm: filter disallowed nodes from arch specific show_mem functions 2011-05-25T15:39:03+00:00 David Rientjes rientjes@google.com 2011-05-25T00:11:16+00:00 7bf02ea22c6cdd09e2d3f1d3c3fe366b834ae9af 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.
