sparse can't parse a struct definition in include/asm-powerpc/lppaca.h, even though gcc can accept it. The form looks like this: struct __attribute__((whatever)) foo { }; An equivalent that both gcc and sparse can handle is struct foo { } __attribute__((whatever)); This is the only definition of this type in the tree, and fixing it is easier than fixing sparse. Signed-off-by:Bryan O'Sullivan <bos@serpentine.com> [ Side note: fixing sparse wouldn't be hard, but the "attribute at the end" version is the canonical one, and the one that makes sense. So let's just fix the kernel instead. Luc Van Oostenryck already sent out a sparse patch to the sparse mailing list in case anybody cares. -- Linus ] Signed-off-by:

sbusfb_compat_ioctl() needs to return int, not long, as that is what the fb_ops->fb_compat_ioctl method prototype wants. Need to git rid of the "struct file *file" first argument to fbiogetputcmap() and fbiogscursor() to match calls done in sbusfb_compat_ioctl(). Signed-off-by: -

this patch changes if() BUG(); constructs in iommu.c to BUG_ON(); so it gets save to define BUG() and BUG_ON() to nullstatements. Signed-off-by:

Ensure a consistent value is read from the STICK register by ensuring that both high and low are read without high changing due to a roll over of the low register. Various Debian/SPARC users (myself include) have noticed problems with Hummingbird based systems. The symptoms are that the system time is seen to jump forward 3 days, 6 hours, 11 minutes give or take a few seconds. In many cases the system then hangs some time afterwards. I've spotted a race condition in the code to read the STICK register. I could not work out why 3d, 6h, 11m is important but guess that it is due to the 2^32 jump of STICK (forwards on one read and then the next read will seem to be backwards) during a timer interrupt. I'm guessing that a change of -2^32 will get converted to a large unsigned increment after the arithmetic manipulation between STICK, nanoseconds, jiffies etc. I did a test where I modified __hbird_read_stick to artificially inject rollover faults forcefully every few seconds. With this I saw the clock jump over 6 times in 12 hours compared to once every month or so. Signed-off-by:

Using __get_cpu_var(obj) is slightly faster than per_cpu_ptr(obj, raw_smp_processor_id()). 1) Smaller code and memory use For static and small objects, DEFINE_PER_CPU(type, object) is preferred over a alloc_percpu() : Better and smaller code to access them, and no extra memory (storing the pointer, and the percpu array of pointers) x86_64 code before patch mov 1237577(%rip),%rax # ffffffff803e5990 <rt_cache_stat> not %rax # part of per_cpu machinery mov %gs:0x3c,%edx # get cpu number movslq %edx,%rdx # extend 32 bits cpu number to 64 bits mov (%rax,%rdx,8),%rax # get the pointer for this cpu incl 0x38(%rax) x86_64 code after patch mov $per_cpu__rt_cache_stat,%rdx mov %gs:0x48,%rax # get percpu data offset incl 0x38(%rax,%rdx,1) 2) False sharing avoidance for SMP : For a small NR_CPUS, the array of per cpu pointers allocated in alloc_percpu() can be <= 32 bytes. This let slab code gives a part of a cache line. If the other part of this 64 bytes (or 128 bytes) cache line is used by a mostly written object, we can have false sharing and expensive per_cpu_ptr() operations. Size of rt_cache_stat is 64 bytes, so this patch is not a danger of a too big increase of bss (in UP mode) or static per_cpu data for SMP (PERCPU_ENOUGH_ROOM is currently 32768 bytes) Signed-off-by:

Some subsystems, such as PPP, can send negative values here. It just happened to work correctly on 32-bit with an unsigned value, but on 64-bit this explodes. Figured out by Paul Mackerras based upon several PPP crash reports. Signed-off-by: -

Add nvram lock count so that calls to tg3_nvram_lock()/unlock() can be nested. Add error checking to all callers of tg3_nvram_lock() where appropriate. To prevent nvram lock failures after halting the firmware, it is also necessary to release firmware's nvram lock in tg3_halt_cpu(). Update version to 3.48. Based on David Miller's initial patch.

Currently when PRIO is configured to use N bands, it lets the packets be directed to any of the bands 0..N-1. However, PRIO attaches a fifo qdisc only to the bands that appear in the priomap; the rest of the N bands remain with a noop qdisc attached. This patch changes PRIO's behavior so that it attaches a fifo qdisc to all of the N bands. Signed-off-by:
