2007-11-14CRISv10 fasttimer: Scrap INLINE and name timeval_cmp betterJesper Nilsson
Scrap the local __INLINE__ macro, and rename timeval_cmp to fasttime_cmp. Inline macro was completely unnecessary since the macro was defined locally to be inline. timeval_cmp was inaccurately named since it does comparison on struct fasttimer_t and not on struct timeval.

Improve and bugfix CRIS v10 fast timers. - irq_handler_t now only takes two arguments. - Keep interrupts disabled as long as we have a reference to the fasttimer list and only enable them while doing the callback. del_fast_timer may be called from other interrupt context. - Fix bug where debug code could return without calling local_irq_restore. - Use jiffies instead of usec (change from struct timeval to fasttime_t). - Don't initialize static variables to zero. - Remove obsolete #ifndef DECLARE_WAITQUEUE code. - fast_timer_init should be __initcall. - Change status/debug variables to unsigned. - Remove CVS log and CVS id.

New and improved serial driver for CRISv10, take three, with improvements suggested by Jiri Slaby. - Call wait_event_interruptible with a _correct_ and sensible condition. - Removed superfluous test of info->flags & ASYNC_CLOSING, since that is done by wait_event_interruptible. - Moved common code for deregistering DMA and IRQ to deinit_port function. - Use setup_timer when initializing flush_timer. - Convert bit-field for uses_dma_in and uses_dma_out to regular bytes. - Removed CVS tags. - Removed defines and comments for CRIS_BUF_SIZE and TTY_THRESHOLD_THROTTLE (no longer used). - Cleaned up code to pass checkpatch. - Add crisv10.h header file. - Merge of CRISv10 from Axis internal CVS.

Corrects compile errors and the following: - Remove oldset parameter from do_signal and do_notify_resume. - Modified to fit new consolidated IRQ handling code. - Reverse check order between external nmi and watchdog nmi to avoid false watchdog oops in case of a glitch on the nmi pin. - Return from an pin-generated NMI the same way as for other interrupts. - Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to low-level asm interrupt handlers. Fixed in the multiple interrupt handler also. - Add space for thread local storage in thread_info struct. - Add NO_DMA to Kconfig, and include arch specific Kconfig using arch independent path.

2007-11-14cris build fixes: update eth_v10.c ethernet driverJesper Nilsson
New (updated) version of ethernet driver for cris v10. - First steps to simplify and make the MII code more similar between the etrax100 and etraxfs ports. - Start the transmit queue before enabling tx interrupts to avoid race with the first frame. - Flip the comparition statement to stick to physical addresses to avoid phys_to_virt mapping a potential null pointer. This was not an error but the change simplifies debugging of address-space mappings. - Made myPrevRxDesc local to e100_rx since it was only used there. Fixed out of memory handling in e100_rx. If dev_alloc_skb() fails persistently the system is hosed anyway but at least it won't loop in an interrupt handler. - Correct some code formatting issues. - Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

2007-11-14x86: don't call mce_create_device on CPU_UP_PREPAREAndreas Herrmann
Fix regression introduced with d435d862baca3e25e5eec236762a43251b1e7ffc ("cpu hotplug: mce: fix cpu hotplug error handling"). A CPU which was not brought up during boot (using maxcpus and additional_cpus parameters) couldn't be onlined anymore. For such a CPU it seemed that MCE was not supported during CPU_UP_PREPARE-time which caused mce_cpu_callback to return NOTIFY_BAD to notifier_call_chain. To fix this we: - call mce_create_device for CPU_ONLINE event (instead of CPU_UP_PREPARE), - avoid mce_remove_device() for the CPU that is not correctly initialized by mce_create_device() failure, - make mce_cpu_callback always return NOTIFY_OK for CPU_ONLINE event. Because CPU_ONLINE callback return value is always ignored.

2007-11-14uml: fix spurious IRQ testingJeff Dike
The spurious IRQ testing in request_irq is mishandled in um_request_irq, which sets the incoming file descriptors non-blocking only after request_irq succeeds. This results in the spurious irq calling read on a blocking descriptor, and a hang. Fixed by reversing the O_NONBLOCK setting and the request_irq call.

2007-11-14Fix 64KB blocksize in ext3 directoriesJan Kara
With 64KB blocksize, a directory entry can have size 64KB which does not fit into 16 bits we have for entry lenght. So we store 0xffff instead and convert value when read from / written to disk. The patch also converts some places to use ext3_next_entry() when we are changing them anyway.

2007-11-14hibernate: fix lockdep reportJohannes Berg
Lockdep reports a circular locking dependency in the hibernate code because - during system boot hibernate code (from an initcall) locks pm_mutex and then a sysfs buffer mutex via name_to_dev_t - during regular operation hibernate code locks pm_mutex under a sysfs buffer mutex because it's called from sysfs methods. The deadlock can never happen because during initcall invocation nothing can write to sysfs yet. This removes the lockdep report by marking the initcall locking as being in a different class.

2007-11-14__do_IRQ does not check IRQ_DISABLED when IRQ_PER_CPU is setRuss Anderson
In __do_IRQ(), the normal case is that IRQ_DISABLED is checked and if set the handler (handle_IRQ_event()) is not called. Earlier in __do_IRQ(), if IRQ_PER_CPU is set the code does not check IRQ_DISABLED and calls the handler even though IRQ_DISABLED is set. This behavior seems unintentional. One user encountering this behavior is the CPE handler (in arch/ia64/kernel/mca.c). When the CPE handler encounters too many CPEs (such as a solid single bit error), it sets up a polling timer and disables the CPE interrupt (to avoid excessive overhead logging the stream of single bit errors). disable_irq_nosync() is called which sets IRQ_DISABLED. The IRQ_PER_CPU flag was previously set (in ia64_mca_late_init()). The net result is the CPE handler gets called even though it is marked disabled. If the behavior of not checking IRQ_DISABLED when IRQ_PER_CPU is set is intentional, it would be worthy of a comment describing the intended behavior. disable_irq_nosync() does call chip->disable() to provide a chipset specifiec interface for disabling the interrupt, which avoids this issue when used.

2007-11-14pidns: Place under CONFIG_EXPERIMENTALEric W. Biederman
This is my trivial patch to swat innumerable little bugs with a single blow. After some intensive review (my apologies for not having gotten to this sooner) what we have looks like a good base to build on with the current pid namespace code but it is not complete, and it is still much to simple to find issues where the kernel does the wrong thing outside of the initial pid namespace. Until the dust settles and we are certain we have the ABI and the implementation is as correct as humanly possible let's keep process ID namespaces behind CONFIG_EXPERIMENTAL. Allowing us the option of fixing any ABI or other bugs we find as long as they are minor. Allowing users of the kernel to avoid those bugs simply by ensuring their kernel does not have support for multiple pid namespaces.
