Bernhard Walle authored
irqpoll is broken on some architectures that don't use the IRQ 0 for the timer interrupt like IA64. This patch adds a IRQF_IRQPOLL flag. Each architecture is handled in a separate pach. As I left the irq == 0 as condition, this should not break existing architectures that use timer_irq == 0 and that I did't address with that patch (because I don't know). This patch: This patch adds a IRQF_IRQPOLL flag that the interrupt registration code could use for the interrupt it wants to use for IRQ polling. Because this must not be the timer interrupt, an additional flag was added instead of re-using the IRQF_TIMER constant. Until all architectures will have an IRQF_IRQPOLL interrupt, irq == 0 will stay as alternative as it should not break anything. Also, note_interrupt() is called on CPU-specific interrupts to be used as interrupt source for IRQ polling. Signed-off-by:

Make UDF work correctly for files larger than 1GB. As no extent can be longer than (1<<30)-blocksize bytes, we have to create several extents if a big hole is being created. As a side-effect, we now don't discard preallocated blocks when creating a hole. Signed-off-by:

Add a few assertions into udf_discard_prealloc() to check that the file is sane (mostly helps debugging further patches ;). Signed-off-by:

Make UDF use get_bh() instead of directly accessing b_count and use brelse() instead of udf_release_data() which does just brelse()... Signed-off-by:

Use sector_t and loff_t for file offsets in UDF filesystem. Otherwise an overflow may occur for long files. Also make inode_bmap() return offset in the extent in number of blocks instead of number of bytes - for most callers this is more convenient. Signed-off-by:

Change the atomic_t in struct nfs_server to atomic_long_t in anticipation of machines that can handle 8+TB of (4K) pages under writeback. However I suspect other things in NFS will start going *bang* by then. Signed-off-by:

Allow a pcap device to be assigned a MAC on the command line. They don't really need one, but it is handy to be able to do when your distro assigns a new ethernet device whenever it sees a new MAC. Signed-off-by:

Some network device cleanup. When setup_etheraddr found a globally valid MAC being assigned to an interface, it went ahead and used it rather than assigning a random MAC like the other cases do. This isn't really an error like the others, but it seems consistent to make it behave the same. We were getting some duplicate kfree() in the error case in eth_configure because platform_device_unregister frees buffers that the error cases following tried to free again. The pcap initialization routine wasn't doing the proper printk of its information, causing a printk of the first part of that line to be unterminated by a newline. The pcap code had a bunch of style violations, which are now fixed. pcap_setup wasn't returning false when it detected an unrecognized option. The printks in pcap_user all got UM_KERN_BLAH prepended to their format strings. pcap_remove now checks for a non-NULL pcap structure before it calls pcap_close. Signed-off-by:

i386: Rearrange the cmpxchg code to allow atomic.h to get it without needing to include system.h. This kills warnings in the UML build from atomic.h about implicit declarations of cmpxchg symbols. The i386 build presumably isn't seeing this because a separate inclusion of system.h is covering it over. The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in system.h for the benefit of generic code which expects cmpxchg there. Meanwhile, atomic.h includes cmpxchg.h. This causes no noticable damage to the i386 build. x86_64: Move cmpxchg into its own header. atomic.h already included system.h, so this is changed to include cmpxchg.h. This is purely cleanup - it's not fixing any warnings - so if the x86_64 system.h isn't considered as cleanup-worthy as i386, then this can be dropped. It causes no noticable damage to the x86_64 build. uml: The i386 and x86_64 cmpxchg patches require an asm-um/cmpxchg.h for the UML build. Signed-off-by:

This series extena and standardises local_t operations on each architecture, allowing a rich set of atomic operations to be done on per-cpu data with minimal performance impact. On architectures where there seems to be no difference between the SMP and UP operation (same memory barriers, same LOCKing), local.h simply includes asm-generic/local.h, which removes duplicated code from the current kernel tree. This patch: local_t: architecture independent extension Signed-off-by:

atomic_add_unless as inline. Remove system.h atomic.h circular dependency. I agree (with Andi Kleen) this typeof is not needed and more error prone. All the original atomic.h code that uses cmpxchg (which includes the atomic_add_unless) uses defines instead of inline functions, probably to circumvent a circular dependency between system.h and atomic.h on powerpc (which my patch addresses). Therefore, it makes sense to use inline functions that will provide type checking. atomic_add_unless as inline. Remove system.h atomic.h circular dependency. Digging into the FRV architecture shows me that it is also affected by such a circular dependency. Here is the diff applying this against the rest of my atomic.h patches. It applies over the atomic.h standardization patches. Signed-off-by:

Remove an explicit cast to an integer type for the result returned by cmpxchg. It is not per se a problem on the i386 architecture, because sizeof(int) == sizeof(long), but whenever this code is cut'n'pasted to a accept passing an atomic64_t value as parameter to cmpxchg, xchg and add_unless, having 64 bits inputs casted to 32 bits.
