These are needed due to a cache bug, and can be used to make sure that the DMA descriptors are flushed to memory and can be safely handled by DMA. flush_dma_descr - Flush one DMA descriptor. flush_dma_list - Flush a complete list of DMA descriptors. cris_flush_cache - Flush the complete cache. cris_flush_cache_range - Flush only the specified range Signed-off-by:

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. Include subsystem Kconfigs for pcmcia, usb, i2c, rtc and pci. Signed-off-by:

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.

Fix regression introduced with d435d862 ("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.

Fix http://bugzilla.kernel.org/show_bug.cgi?id=9247 Allow sigcont to be sent to a process with greater capabilities if it is in the same session. Otherwise, a shell from which I've started a root shell and done 'suspend' can't be restarted by the parent shell. Also don't do file-capabilities signaling checks when uids for the processes don't match, since the standard check_kill_permission will have done those checks.

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. Signed-off-by:

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.
