2012-04-13sparc64: Fix bootup crash on sun4v.David S. Miller1-1/+1
The DS driver registers as a subsys_initcall() but this can be too early, in particular this risks registering before we've had a chance to allocate and setup module_kset in kernel/params.c which is performed also as a subsyts_initcall(). Register DS using device_initcall() insteal. Signed-off-by: David S. Miller <davem@davemloft.net> Cc: stable@vger.kernel.org
2012-03-28powerpc+sparc/vio: Modernize driver registrationBenjamin Herrenschmidt1-4/+1
This makes vio_register_driver() get the module owner & name at compile time like PCI drivers do, and adds a name pointer directly in struct vio_driver to avoid having to explicitly initialize the embedded struct device.

2012-02-28sparc: Use vsprintf extention %pf with builtin_return_addressJoe Perches1-1/+1
Emit the function name not the address when possible. builtin_return_address() gives an address. When building a kernel with CONFIG_KALLSYMS, emit the actual function name not the address. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-16sparc: convert old cpumask API into new oneKOSAKI Motohiro1-7/+7
Adapt new API. Almost change is trivial, most important change are to remove following like =operator. cpumask_t cpu_mask = *mm_cpumask(mm); cpus_allowed = current->cpus_allowed; Because cpumask_var_t is =operator unsafe. These usage might prevent kernel core improvement. No functional change. Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-30sparc64: Fix section mis-match errors.David S. Miller1-1/+1
Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under arch/sparc during a 64-bit defconfig build. They fall into two categorites: 1) of_device_id is marked as __initdata, and we can never do this since these objects sit in the device core data structures way past boot. So even if a driver will never be reloaded, we have to keep the device ID table around. Mark such cases const instead. 2) The bootmem alloc/free handling code in mdesc.c was not fully marked __init as it should be, thus generating a reference to free_bootmem_late() (which is __init) from non-__init code.

2009-03-16cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits.: sparc64Rusty Russell1-1/+1
Impact: cleanup, futureproof In fact, all cpumask ops will only be valid (in general) for bit numbers < nr_cpu_ids. So use that instead of NR_CPUS in various places. This is always safe: no cpu number can be >= nr_cpu_ids, and nr_cpu_ids is initialized to NR_CPUS at boot.

2009-01-06sparc64: Use unsigned long long for u64.Sam Ravnborg1-17/+17
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.

2008-12-04sparc,sparc64: unify kernel/Sam Ravnborg1-0/+1244
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.
