As we no longer support sun4c we can remove all the code to support remapping the kernel in head_32.S. We also try to tell the user that the machine is not support, in case someone try to boot the kernel on a sun4c one day Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

We used to runtime patch the trap table for srmmu. With the removal of sun4c support this is no longer required. With the sun4c trap removed we can remove all the referenced trap handling which is sun4c specific. This also allows us to get rid of the nosun4c.c file that contained only dummy functions/data.

Machines with sun4c support are very rare these days, and noone is using them for any practical purposes. The sun4c support has been know broken for quite some time too. So rather than trying to keep it up-to-date, lets get rid of it. This allows us to do some very welcome cleanup of sparc32 support. Updated the former sun4c specifc nmi (which was also used for sun4m UP) to be a generic UP NMI. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Commit 625d693e (linux-next) "sparc64: Convert over to NO_BOOTMEM." causes the following compile failure for sparc64 allnoconfig: arch/sparc/mm/init_64.c:822:16: error: unused variable 'paddr' arch/sparc/mm/init_64.c:1759:7: error: unused variable 'node' arch/sparc/mm/init_64.c:809:12: error: 'memblock_nid_range' defined but not used The paddr decl can easily be shuffled within the ifdef. The memblock_nid_range is just a stub function for when NEED_MULTIPLE_NODES is off, but the only caller is within a NEED_MULTIPLE_NODES enabled section, so we can simply delete it. The unused "node" is slightly more interesting. In the case of "# CONFIG_NEED_MULTIPLE_NODES is not set" we no longer get the definition of: #define NODE_DATA(nid) (node_data[nid]) from arch/sparc/include/asm/mmzone.h - but instead we get: #define NODE_DATA(nid) (&contig_page_data) from include/linux/mmzone.h -- and since the arg is ignored, the thing really is unused. Rather than put in a confusing looking __maybe_unused, simply splitting the declaration from the assignment seemed to me to be the least offensive. Cc: Sam Ravnborg <sam@ravnborg.org> Cc: "David S.
