When CONFIG_UTS_NS=n, clone(CLONE_NEWUTS) quietly refuses. So correctly does not unshare a new uts namespace, but also does not return -EINVAL. Fix this to return -EINVAL so the caller knows his request was denied. Signed-off-by:

On Bob's machine clocksource is selecting PIT over the ACPI PM timer, because he has the PIIX4 bug. That bug drops the ACPI PM timers rating to the same as the PIT, so that's why you're getting the PIT. Realistically, the PIT is much slower then even the triple read ACPI PM, so the de-ranking code is probably dropping it too far. So don't drop ACPI PM quite so low if we see the PIIX4 bug.

Commit d720bc4b partially removed a private implementation of baud speed decoding. However it doesn't seem to be complete: after the speed is decoded, it is still being used as an index to a local speed table (array overrun, no doubt). This was found by Graham Murray who noticed it caused a 2.6.19 regression with the SX driver: https://bugs.gentoo.org/170554Signed-off-by:

->readdir passes lofft_t offsets (used as nfs cookies) to nfs3svc_encode_entry{,_plus}, but when they pass it on to encode_entry it becomes an 'off_t', which isn't good. So filesystems that returned 64bit offsets would lose. Signed-off-by: -

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.)

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 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:
