| | | | | | | | | | | | | | | | | | | | In the unlikely event that an AP device lost requests, don't forget to update the ap_poll_requests counter too. Same must happen in case an AP device is removed while there are still outstanding requests.

| * [S390] zcrypt: Fix possible dead lock in AP bus module.Ralph Wuerthner2007-03-26
| | | | | | | | | | | | | | | | | | | | | | | | If a AP device is unconfigured __ap_poll_all() will call device_unregister() in software interrupt context which can cause dead locks. To fix this the device will be only marked as unconfigured and the device_unregister() call will be done later by either ap_scan_bus() or ap_queue_message() in process context.

| * [S390] kprobes: Align probe address.David Wilder2007-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running a probe on s390 with a probe address that is not 4 byte aligned results in a Kernel BUG. The problem is that the stura instruction used by swap_instruction requires the destination address to be 4 byte aligned. As stura only writes 4 bytes, aligning to the next 4 byte aligned address results in the breakpoint instruction being stored past the probe address. The fix is to align the address backward (to the previous 4 byte aligned address) and writing the two byte breakpoint instruction in the appropriate bytes.

| * [S390] Fix TCP/UDP pseudo header checksum computation.Heiko Carstens2007-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git commit f994aae1bd8e4813d59a2ed64d17585fe42d03fc changed the function declaration of csum_tcpudp_nofold. Argument types were changed from unsigned long to __be32 (unsigned int). Therefore we lost the implicit type conversion that zeroed the upper half of the registers that are used to pass parameters. Since the inline assembly relied on this we ended up adding random values and wrong checksums were created. Showed only up on machines with more than 4GB since gcc produced code where the registers that are used to pass 'saddr' and 'daddr' previously contained addresses before calling this function. Fix this by using 32 bit arithmetics and convert code to C, since gcc produces better code than these hand-optimized versions.

This resolves really NASTY problems with logspamming via WARN_ON(), indicating N-page leaks. - Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the previous code only handled RECIP_INTERFACE, this version should be correct except for (sigh) bulk/interrupt endpoints. - Provide a better name for the function reporting whether the board has vbus sensing wired up. GET_STATUS requests for endpoint status still acts strangely though, at least given one flakey host doesn't always ack the first DATA packet, then the packet that gets retransmitted doesn't have data!

This violates the ATA spec (can only send IDLE IMMEDIATE when drive is not busy) and really hoses up some drives (modern drives will not be able to recover using this error handling). The correct thing to do is issue a SRST followed by a SET FEATURES command. This is what Western Digital recommends for error recovery and what Western Digital says Windows does.  It also does not violate the ATA spec as far as I can tell. Bart: * port the patch over the current tree * undo the recalibration code removal * send SET FEATURES command after checking for good drive status * don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK} type because we need to send SET FEATURES before handling any requests * some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before other commands (except IDENTIFY) so send SET FEATURES only if there are no pending drive->special requests * update comments and patch description * any bugs introduced by this patch are mine and not Suleiman's :-) Signed-off-by: Suleiman Souhlal <suleiman@google.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since hwif->ide_dma_check and hwif->ide_dma_on never queue any commands (ide_config_drive_speed() sets transfer mode using polling and has no error recovery) we are safe with setting hwgroup->busy for the time while DMA setting for a drive is changed (so it won't race against I/O commands in fly). I audited briefly all ->ide_dma_check/->ide_dma_on/->tuneproc/->speedproc implementations and they all look OK wrt to this change.

[ Unfortunately the fact that IDE driver doesn't reset devices itself helps only a bit as it seems that some BIOS-es reset ATA devices after programming the chipset, some BIOS-es can be set to not probe/configure selected devices, there may be no BIOS in case of add-on cards etc. ] Since we are quite late in the release cycle and the required changes will affect a lot of systems just revert the fix for now.

* [PATCH] dynticks: fix hrtimer rounding error in next_timer_interruptThomas Gleixner2007-03-25
| | | | | | | | | | | | | | | | | | | | | | | | The rework of next_timer_interrupt() fixed the timer wheel bugs, but invented a rounding error versus the next hrtimer event. This is caused by the conversion of the hrtimer internal representation to relative jiffies. This causes bug #8100: http://bugzilla.kernel.org/show_bug.cgi?id=8100 next_timer_interrupt() returns "now" in such a case and causes the code in tick_nohz_stop_sched_tick() to trigger the timer softirq, which is bogus as no timer is due for expiry. This results in an endless context switching between idle and ksoftirqd until a timer is due for expiry. Modify the hrtimer evaluation so that, it returns now + 1, when the conversion results in a delta < 1 jiffie.
