* checkpatch: add checks for question mark and colon spacingAndy Whitcroft2008-07-241-9/+72
| | | | | | | | | | | | | | | Add checks for the question mark colon operator spacing, and also check the other uses of colon. Colon means a number of things: - it introduces the else part of the ?: operator, - it terminates a goto label, - it terminates the case value, - it separates the identifier from the bit size on bit fields, and - it is used to introduce option types in asm().

* generic irqs: handle failure of irqchip->set_type in setup_irqUwe Kleine-König2008-07-241-22/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | set_type returns an int indicating success or failure, but up to now setup_irq ignores that. In my case this resulted in a machine hang: gpio-keys requested IRQF_TRIGGER_RISING | IRQF_TRIGGER_FALLING, but arm/ns9xxx can only trigger on one direction so set_type didn't touch the configuration which happens do default to a level sensitiveness and returned -EINVAL. setup_irq ignored that and unmasked the irq. This resulted in an endless triggering of the gpio-key interrupt service routine which effectively killed the machine. With this patch applied setup_irq propagates the error to the caller. Note that before in the case chip && !chip->set_type && !chip->name a NULL pointer was feed to printk. This is fixed, too.

* remove the v850 portAdrian Bunk2008-07-24204-18406/+5
| | | | | | | | | | | | | | | | | | | Trying to compile the v850 port brings many compile errors, one of them exists since at least kernel 2.6.19. There also seems to be noone willing to bring this port back into a usable state. This patch therefore removes the v850 port. If anyone ever decides to revive the v850 port the code will still be available from older kernels, and it wouldn't be impossible for the port to reenter the kernel if it would become actively maintained again.

* pm: acpi hibernation: utilize hardware signatureShaohua Li2008-07-244-1/+30
| | | | | | | | | | | | | | | | | | | | | | ACPI defines a hardware signature. BIOS calculates the signature according to hardware configure and if hardware changes while hibernated, the signature will change. In that case, S4 resume should fail. Still, there may be systems on which this mechanism does not work correctly, so it is better to provide a workaround for them. For this reason, add a new switch to the acpi_sleep= command line argument allowing one to disable hardware signature checking.

* pm: boot time suspend selftestDavid Brownell2008-07-243-2/+212
| | | | | | | | | | | | | | | | | | | | | | | | | | | Boot-time test for system suspend states (STR or standby). The generic RTC framework triggers wakeup alarms, which are used to exit those states. - Measures some aspects of suspend time ... this uses "jiffies" until someone converts it to use a timebase that works properly even while timer IRQs are disabled. - Triggered by a command line parameter. By default nothing even vaguely troublesome will happen, but "test_suspend=mem" will give you a brief STR test during system boot. (Or you may need to use "test_suspend=standby" instead, if your hardware needs that.) This isn't without problems. It fires early enough during boot that for example both PCMCIA and MMC stacks have misbehaved. The workaround in those cases was to boot without such media cards inserted.
