Make x86 COM ports into platform devices and don't probe for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp, e.g., serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A This also means IRDA devices without a UART PNP ID will no longer be claimed by the serial driver, which might require changes in IRDA drivers and administration. In addition to this patch, you may need to configure a setserial init script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel" option does this. To force the old legacy probe behavior even when we have PNPBIOS or ACPI, load the new legacy_serial module (or build 8250 static) with the "legacy_serial.force" option.

Claim devices using PNP, unless the user explicitly specified device addresses. This can be disabled with the "smsc-ircc2.nopnp" option. This removes the need for probing legacy addresses and helps untangle IR devices from serial8250 devices. Sometimes the SMC device is at a legacy COM port address but does not use the legacy COM IRQ. In this case, claiming the device using PNP rather than 8250 legacy probe means we can automatically use the correct IRQ rather than forcing the user to use "setserial" to set the IRQ manually. If the PNP claim doesn't work, make sure you don't have a setserial init script, e.g., /etc/init.d/setserial, configured to poke in legacy COM port resources for the IRDA device. That causes the serial driver to claim resources needed by this driver.

Some HP/Compaq firmware reports via ACPI that the SMCF010 IR device is enabled, but in fact, it leaves the device partly disabled. HP nw8240 BIOS 68DTV Ver. F.0F, released 9/15/2005 is one BIOS that has this problem. Signed-off-by:

This series converts i386 and x86_64 legacy serial ports to be platform devices and prevents probing for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp. This also prevents the serial driver from claiming IRDA devices (unless they have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ, so the user had to use "setserial" to fix it. Removing the need for setserial to make IRDA devices work seems good, but it does break some things. In particular, you may need to keep setserial from poking legacy UART stuff back in by doing something like "dpkg-reconfigure setserial" with the "kernel" option. Otherwise, the setserial-discovered "UART" will claim resources and prevent the IRDA driver from loading. This patch: If we can discover devices using PNP, we can skip some legacy probes. This flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and should tell us about builtin devices. Signed-off-by: -

Add IRQF_IRQPOLL for the timer interrupt on x86_64. Signed-off-by:

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:

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:

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:
