Change prototypes for __chk_user_ptr and __chk_io_ptr to take const void* instead of void*, so that code can pass "const void *" to them. (Right now sparse does not warn about passing const void* to void* functions, but that is a separate bug that I believe Josh is working on, and once sparse does check this, the changed prototypes will be necessary.)

Both airprime and option now want to handle vendor ID 0x1410, device ID 0x1100. Airprime calls it 'ExpressCard34 Qualcomm 3G CDMA'. Option calls it 'Novatel Merlin XS620/S640'. Patch attached to remove it from airprime. From: Jon K Hellan <jon.kare.hellan@uninett.no> Signed-off-by: -

Various fixes to omap_udc, noted with some recent testing: - Cope with some SMP-induced braindamage in ARM's dma_{alloc,free}_coherent() implementation: alloc() can be called with IRQs blocked, but since late last year that's no longer true for free(). 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 patch (as871) fixes a problem introduced by an earlier change. It turns out that some systems really do need to have a terminating skeleton QH present whenever FSBR is on. I don't know any way to tell which systems do need it and which don't; the easiest answer is to have it there always. This fixes the NumLock-hang bug reported by Jiri Slaby. Signed-off-by:

It was found that the Toshiba laptops with hidden Intel SMBus have SMM code handling the thermal management which accesses the SMBus. Thus it is not safe to unhide it and let Linux access it. We have to leave the SMBus hidden. SMM is a pain, really. This fixes bugs #6315 and #6395, for good this time. Signed-off-by:

IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set. 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:

[ bart: the ressurection of 2 years old patch which slipped thru the cracks (thanks to Sergei Shtylyov for finding it) ] These is the patch to turn on pdc202xx_new for ATAPI DMA. When testing, it works fine without the (request_bufflen % 256) workaround as needed in libata. ide-scsi filters out (pc->request_transfer % 1024) and use PIO, so the pdc202xx ATAPI DMA problem is avoid. Both ide-cd and ide-scsi won't hit the ATAPI DMA problem on pdc202xx_new. Signed-off-by:

Since especially Serial ATA has it's own menu point now, I guess we can change the description of the deprecated SATA driver as well, since the new libATA subsystem is not configured through a SCSI low-level driver anymore, but has it's own menu point.

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. This patch finally allowed me to close kernel bugzilla bug #8169 (once again thanks to Patrick Horn for reporting the issue & testing patches).

"ide: fix drive side 80c cable check, take 2" patch from Tejun Heo (commit fab59375) fixed 80c bit test (bit13 of word93) but we also need to fix master/slave IDENTIFY order (slave device should be probed first in order to make it release PDIAG- signal) and we should also check for pre-ATA3 slave devices (which may not release PDIAG- signal). [ 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. [ Please also see libata commit f31f0cc2. ] Thanks goes out to Fernando Mitio Yamada for reporting the problem and patiently testing patches. Acked-by:

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.

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.

git commit f994aae1 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. Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by:

Thomas Gleixner authored
The watchdog implementation excludes low res / non continuous clocksources from being selected as a watchdog reference unintentionally. Allow using jiffies/PIT as a watchdog reference as long as no better clocksource is available. This is necessary to detect TSC breakage on systems, which have no pmtimer/hpet. The main goal of the initial patch (preventing to switch to highres/nohz when no reliable fallback clocksource is available) is still guaranteed by the checks in clocksource_watchdog().

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. It's confirmed to resolve bug #8100 Reported-by:

It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

commit f9690982 removed the check for cpu_khz from sched_clock(), which prevented early access to the TSC by non obvious magic. This is harmless as long as the CPU has a TSC. On TSCless systems this results in an illegal instruction trap. Replace tsc_disabled and tsc_unstable by tsc_enabled, which is only set when the tsc is available and not unstable. Signed-off-by:
