2008-10-21V4L/DVB (9322): v4l2-int-if: Export more interfaces to modulesSakari Ailus
Export v4l2_int_device_try_attach_all. This allows initiating the initialisation of int if device after the drivers have been registered. Also allow drivers to call ioctls if v4l2-int-if was compiled as module.

the desired modulation If we are already at the desired modulation, there is no need to reconfigure the demod (at a tuning time cost) Note that this change revealed that although the datasheet says the demod starts out in VSB-8 mode, the first tuning was failing consistently unless we went through the work of setting the registers. So add a field to denote this case so we always do the enable_frontend call, even if the first tuning request is for VSB-8.

If you instruct the tuner to change frequencies, it can take up to 2500ms to get a demod lock. By performing a soft reset after the tuning call (which is consistent with how the Pinnacle 801e Windows driver behaves), you get a demod lock inside of 300ms Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Reviewed-by: Michael Krufky <mkrufky@linuxtv.org> Acked-by: Steven Toth <stoth@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-21V4L/DVB (9300): pvrusb2: Fix deadlock problemMike Isely
Fix deadlock problem in 2.6.27 caused by new USB core behavior in response to a USB device reset request. With older kernels, the USB device reset was "in line"; the reset simply took place and the driver retained its association with the hardware. However now this reset triggers a disconnect, and worse still the disconnect callback happens in the context of the caller who asked for the device reset. This results in an attempt by the pvrusb2 driver to recursively take a mutex it already has, which deadlocks the driver's worker thread. (Even if the disconnect callback were to happen on a different thread we'd still have problems however - because while the driver should survive and correctly disconnect / reconnect, it will then trigger another device reset during the repeated initialization, which will then cause another disconect, etc, forever.) The fix here is simply to not attempt the device reset (it was of marginal value anyway). Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-21[CIFS] fix saving of resume key before CIFSFindNextJeff Layton
We recently fixed the cifs readdir code so that it saves the resume key before calling CIFSFindNext. Unfortunately, this assumes that we have just done a CIFSFindFirst (or FindNext) and have resume info to save. This isn't necessarily the case. Fix the code to save resume info if we had to reinitiate the search, and after a FindNext. This fixes connectathon basic test6 against NetApp filers.

2008-10-21rcupdate: fix bug of rcu_barrier*()Lai Jiangshan

My patch uses another way to fix this bug, please see the comment of my patch. Thank Paul E. McKenney for he rewrote the comment.

2008-10-21genirq: NULL struct irq_desc's member 'name' in dynamic_irq_cleanup()Dean Nelson
If the member 'name' of the irq_desc structure happens to point to a character string that is resident within a kernel module, problems ensue if that module is rmmod'd (at which time dynamic_irq_cleanup() is called) and then later show_interrupts() is called by someone. It is also not a good thing if the character string resided in kmalloc'd space that has been kfree'd (after having called dynamic_irq_cleanup()). dynamic_irq_cleanup() fails to NULL the 'name' member and show_interrupts() references it on a few architectures (like h8300, sh and x86).
