2008-12-27sparc: move select of ARCH_SUPPORTS_MSISam Ravnborg
It is counter intuitive to have the select listed as part of the PCI option. Move the select to the SPARC64 specific part of the config. PCI_MSI has a dependency on PCI so it does not harm to have it always selected. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-27sparc: drop SUN_IOSam Ravnborg
SUN_IO is always 'y' so drop it and thus killing an ifdef/endif pair Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
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>

2008-12-26sparc64: 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.

2008-12-26sparc64: use bit neutral Elf symbolsSam Ravnborg

2008-12-26sparc: unify module.hSam Ravnborg
Use some preprocessor magic in combination with the newly introduced CONFIG_BITS to unify module.h. A few additional symbols are added as they are needed in a follow-up patch Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-26sparc: introduce CONFIG_BITSSam Ravnborg
CONFIG_BITS is set to 32 for sparc32 and 64 for sparc64. This allow us to use this symbol in for example header files to ease unification of sparc32 and sparc64. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-26sparc: fix hardirq.h removal falloutSam Ravnborg

2008-12-26cpumask: sparc: Introduce cpumask_of_{node,pcibus} to replace ↵Rusty Russell
{node,pcibus}_to_cpumask Impact: New APIs The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: David S. Miller <davem@davemloft.net>
2008-12-16sparc: We need to implement arch_ptrace_stop().David S. Miller
In order to always provide fully synchronized state to the debugger, we might need to do a synchronize_user_stack(). A pair of hooks, arch_ptrace_stop_needed() and arch_ptrace_stop(), exist to handle this kind of situation. It was created for the sake of IA64. Use them, to flush the kernel side cached register windows to the user stack, when necessary. Signed-off-by: David S. Miller <davem@davemloft.net>

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
Al asked: BTW, why does sparc64 export put_fs_struct? Grepping the kernel tree did not show any users of an exported put_fs_struct - so drop the export. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-11sparc: use sparc64 version of scatterlist.hRobert Reif

2008-12-05sparc: Always set AUDIT_ARCH, not just on sparc64.David S. Miller
Without fancy makefile rules it's not straightforward to prevent both arch/sparc/kernel/audit.o and lib/audit.o from both being used on sparc32. Since arch/sparc/kernel/audit.c is identical to lib/audit.c except some CONFIG_COMPAT protected sections of code, just use it on sparc32 too as that's the simplest way to fix this.
