2009-01-06sparc64: Use unsigned long long for u64.Sam Ravnborg
Andrew Morton wrote: People keep on doing printk("%llu", some_u64); testing it only on x86_64 and this generates a warning storm on powerpc, sparc64, etc. Because they use `long', not `long long'. Quite a few 64-bit architectures are using `long' for their s64/u64 types. We should convert them all to `long long'. Update types.h so we use unsigned long long for u64 and fix all warnings in sparc64 code. Tested with an allnoconfig, defconfig and allmodconfig builds. This patch introduces additional warnings in several drivers. These will be dealt with in separate patches.

2009-01-05sparc: Fix minor SPARC32 compile errorJulian Calaby
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.

2009-01-02sparc: unify openprom.hSam Ravnborg
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.

2009-01-02sparc: unify ptrace.hSam Ravnborg
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.

2009-01-02sparc: add '32' suffix to reg_window, sigcontext, __siginfo_tSam Ravnborg
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.

2009-01-02sparc: unify signal.hSam Ravnborg
They were almost identical and with the preapration patch nothing was needed to be added.
