2011-06-07sparc: Remove unnecessary semicolonsJoe Perches
Semicolons are not necessary after switch/while/for/if braces so remove them. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-07-24sparc: remove references to of_device and to_of_deviceGrant Likely
of_device is just a #define alias to platform_device. This patch replaces all references to it with platform_device. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
2010-05-18of: Always use 'struct device.of_node' to get device node pointer.Grant Likely
The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead. (struct of_device *)->node (struct dev_archdata *)->prom_node (sparc) (struct dev_archdata *)->of_node (powerpc & microblaze) Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2009-01-08sparc64: fix warnings in psycho_common after ull conversionSam Ravnborg
After conversion to use unsigned long long for u64 I saw following warnings: CC arch/sparc/kernel/psycho_common.o arch/sparc/kernel/psycho_common.c: In function `psycho_check_stc_error': arch/sparc/kernel/psycho_common.c:104: warning: long long unsigned int format, long unsigned int arg (arg 4) arch/sparc/kernel/psycho_common.c:104: warning: long long unsigned int format, long unsigned int arg (arg 5) arch/sparc/kernel/psycho_common.c:114: warning: long long unsigned int format, long unsigned int arg (arg 4) arch/sparc/kernel/psycho_common.c:114: warning: long long unsigned int format, long unsigned int arg (arg 5) arch/sparc/kernel/psycho_common.c:114: warning: long long unsigned int format, long unsigned int arg (arg 6) arch/sparc/kernel/psycho_common.c:114: warning: long long unsigned int format, long unsigned int arg (arg 7) arch/sparc/kernel/psycho_common.c: In function `psycho_dump_iommu_tags_and_data': arch/sparc/kernel/psycho_common.c:187: warning: long long unsigned int format, long unsigned int arg (arg 8) arch/sparc/kernel/psycho_common.c:193: warning: long long unsigned int format, long unsigned int arg (arg 6) arch/sparc/kernel/psycho_common.c: In function `psycho_pcierr_intr': arch/sparc/kernel/psycho_common.c:333: warning: long long unsigned int format, long unsigned int arg (arg 3) arch/sparc/kernel/psycho_common.c:333: warning: long long unsigned int format, long unsigned int arg (arg 4) This is due to different integer promotion in my 32 bit hosted gcc. The fix is to force a few constants to ULL. The following stands out from the rest: +#define PSYCHO_IOMMU_TAG_VPAGE 0x7ffffULL +#define PSYCHO_IOMMU_DATA_PPAGE 0xfffffffULL They were needed otherwise the expression: (data_val & PSYCHO_IOMMU_DATA_PPAGE) << IOMMU_PAGE_SHIFT) were promoted to a unsigned long and not a unsigned long long as expected. I tried the alternative solution and made IOMMU_PAGE_SHIFT an ULL but that did not help. The only way gcc would make this expression an unsigned long long was to define PSYCHO_IOMMU_DATA_PPAGE as ULL. The alternative to add a cast was not considered a valid solution. We had this issue in two places and this were the only places the above two constants are used. A small coding style diff sneaked in too.

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.

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.
