This fix has also been applied to lgdt330x. There is an optimization that keeps track of the frequency tuned by the digital decoder. The digital driver does not set the frequency if it has not changed since it was tuned. The analog tuner driver knows nothing about the frequency saved by the digital driver. When the frequency is set using the video4linux code with tvtime, the hardware get changed but the digital driver's state does not get updated. Switch back to the same digital channel and the driver finds no change in frequency so the tuner is not reset to the digital frequency. The work around is to remove the check and always set the tuner to the specified frequency. Signed-off-by:

while investigating the QAM_128-issue with the stv0297-driver for the Cablestar (which is not the same as the one in dvb-kernel CVS, yet), I fixed it, not by increasing the timeout, but by disabling the corner-detection for QAM_128 and higher. This patch has been tested on dvb-kernel cvs, and has been reported to work by multiple users. Some cards still need timeout increase on top of this patch. This will be addressed later.

Fix two problems with the signal strength value in the mt352.c frontend: 1. the 4 most significant bits are zeroed - shift and mask wrong way round 2. need to align the 12 bits from the registers at the top of the 16 bit returned value - otherwise the range is not 0 to 0xffff its 0xf000 to 0xffff Signed-off-by:

I have a system (Biostar IDEQ210M mini-pc with a VIA chipset) which will not reboot unless a keyboard is plugged in to it. I have tried all combinations of the kernel "reboot=x,y" flags to no avail. Rebooting by any method will leave the system in a wedged state (at the "Restarting system" message). I finally tracked the problem down to the machine's refusal to fully reboot unless the keyboard controller status register had bit 2 set. This is the "System flag" which when set, indicates successful completion of the keyboard controller self-test (Basic Assurance Test, BAT). I suppose that something is trying to protect against sporadic reboots unless the keyboard controller is in a good state (a keyboard is present), but I need this machine to be headless. I found that setting the system flag (via the command byte) before giving the "pulse reset line" command will allow the reboot to proceed. The patch is simple, and I think it should be fine for everybody whether they have this type of machine or not. This affects the "hard" reboot (as done when the kernel boot flags "reboot=c,h" are used). Signed-off-by:

Implement a per-kiocb lock to serialise retry operations and cancel. This is done using wait_on_bit_lock() on the KIF_LOCKED bit of kiocb->ki_flags. Also, make the cancellation path lock the kiocb and subsequently release all references to it if the cancel was successful. This version includes a fix for the deadlock with __aio_run_iocbs.

Note that other than few exceptions, most of the current filesystem and/or drivers do not have aio cancel specifically defined (kiob->ki_cancel field is mostly NULL). However, sys_io_cancel system call universally sets return code to -EAGAIN. This gives applications a wrong impression that this call is implemented but just never works. We have customer inquires about this issue. Changed by Benjamin LaHaise to EINVAL instead of ENOSYS Signed-off-by:

Chen, Kenneth W authored
For architecture like ia64, the switch stack structure is fairly large (currently 528 bytes). For context switch intensive application, we found that significant amount of cache misses occurs in switch_to() function. The following patch adds a hook in the schedule() function to prefetch switch stack structure as soon as 'next' task is determined. This allows maximum overlap in prefetch cache lines for that structure. Signed-off-by:

Race is as follows. Process A forks process B, both being part of the same session. Then, A calls disassociate_ctty while B forks C: A B ==== ==== fork() copy_signal() dissasociate_ctty() .... attach_pid(p, PIDTYPE_SID, p->signal->session); Now, C can have current->signal->tty pointing to a freed tty structure, as it hasn't yet been added to the session group (to have its controlling tty cleared on the diassociate_ctty() call). This has shown up as an oops but could be even more serious. I haven't tried to create a test case, but a customer has verified that the patch below resolves the issue, which was occuring quite frequently. I'll try and post the test case if i can. The patch simply checks for a NULL tty *after* it has been attached to the proper session group and clears it as necessary. Alternatively, we could simply do the tty assignment after the the process is added to the proper session group. Signed-off-by:
