* atomic_t: unify all arch definitionsMatthew Wilcox2009-01-062-5/+0
| | | | | | | | | | | | The atomic_t type cannot currently be used in some header files because it would create an include loop with asm/atomic.h. Move the type definition to linux/types.h to break the loop.

| * sparc: Fix minor SPARC32 compile errorJulian Calaby2009-01-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_PROC_FS is unset, include/linux/interrupt.h defines init_irq_proc() as an empty function. arch/sparc/kernel/irq_32.c defines this function unconditionally. Fix the latter so that it only defines this function when CONFIG_PROC_FS is set. This fixes the following error: arch/sparc/kernel/irq_32.c:672: error: redefinition of 'init_irq_proc' include/linux/interrupt.h:461: error: previous definition of 'init_irq_proc' was here This was found using randconfig builds.

| * sparc: Clean arch-specific code in prom_common.cJulian Calaby2009-01-051-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | prom_nextprop() and prom_firstprop() have slightly different calling conventions in 32 and 64 bit SPARC. prom_common.c uses a ifdef guard to ensure that these functions are called correctly. Adjust code to eliminate this ifdef by using a calling convention that is compatible with both 32 and 64 bit SPARC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use 64BIT config entry to distinguish between 32 and 64bit builds instead of relying on the ARCH setting. Using sparc64 as ARCH still forces 64BIT on. Inspired by the x86 and s390 configs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the preparational steps the unification was simple. The linux_prom_pci_registers definition did not look like it could be unified at first look since the structure is assigned using prop_getproperty() / of_get_property() so the structure is assumed to come direct form the prom. The LINUX_OPPROM_MAGIC was kept even if it is not used by the kernel on the assumption that userspace may require it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The two ptrace.h implementations are very alike but the small differences required two set of ifdef/else/endif pairs. The definition of reg_window32 could have been shared but that would have required several updates in sparc32 code as all printk formatting for example assume it is longs. sparc_stackf looked like anohter candidate to share if the 32 bit was renamed to sparc_stackf32. But it contains two pointers in the sparc32 version which would have been 64 bit in the sparc64 version so it was non-trivial. Using a set of accessor macros could do the trick if pursued later. The sparc64 specific definitions are not protected by ifdef - as it should not be required to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | Renaming a few types to contain a 32 suffix makes the type names compatible with sparc64 and thus makes sharing between the two a lot easier.

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.

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>
* | | sparc: move select of ARCH_SUPPORTS_MSISam Ravnborg2008-12-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
