2008-12-27sparc: unify sections.hSam Ravnborg
While doing this use standard names for start/end so we could use definitions straight from asm-generic for all the typical symbols. This also allowed us to drop the use of PROVIDE in the linker script so sprc is less non-standard on this area. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-27sparc: use .data.init_task section for init_thread_unionSam Ravnborg
Use a dedicated aligned section for the init_thread_union variable and declare this section in vmlinux.lds. This align sparc with most other architectures. Eventually this allow the init_task bits to be unified across all architectures. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-26sparc: fix array overrun check in of_device_64.cRobert Reif

2008-12-26sparc64: prepare module_64.c for unificationSam Ravnborg
o Introduce a helper function o Combine sparc64 specific case values o add ifdef's around sparc64 code snippets Note: The ifdef around the BUG_ON is highly questionable but for now the safe approach was taken Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

2008-12-26sparc: fix hardirq.h removal falloutSam Ravnborg

2008-12-13cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell
Impact: cleanup Each SMP arch defines these themselves. Move them to a central location. Twists: 1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a CONFIG_INIT_ALL_POSSIBLE for this rather than break them. 2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'. Those archs simply have phys_cpu_present_map replaced everywhere. 3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky so I just manipulate them both in sync. 4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map' declarations.

2008-12-11sparc64: do not export pus_fs_structSam Ravnborg

2008-12-04sparc: Add missing of_node_putNicolas Palix
of_node_put is needed before discarding a value received from of_find_node_by_name, eg in error handling code or when the device node is no longer used. The semantic match that catches the bug is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression struct device_node *n; position p1, p2; struct device_node *n1; statement S; identifier f; expression E; expression *ptr != NULL; @@ n@p1 = of_find_node_by_name(...) ... if (!n) S ... when != of_node_put(n) when != n1 = f(n,...) when != E = n when any when strict ( return \(0\|<+...n...+>\|ptr\); | return@p2 ...; | of_node_put(n); | n1 = f(n,...) | E = n ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s of_find_node_by_name %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Nicolas Palix <npalix@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-12-04sparc,sparc64: unify kernel/Sam Ravnborg
o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.
