[PATCH 1/6] ia64/perfmon: convert to unlocked_ioctl
The ioctl function in this driver does not do anything that requires the BKL, so make it use unlocked_ioctl.

Radeon KMS doesn't work.
I have a Dell Inspiron 5100 with an ATI Radeon Mobility M7 (7500 R100 PCI ID 1002:4c57 sub 1028:0149). Immediately when radeon.ko is loaded, the screen goes blank (The backlight stays on). I have fbcon compiled into the kernel (I also tried as module). I am unable to get the screen to work again until I reboot.... 6 Jul 2010 00:20

[PATCH 0/6] kill .ioctl file_operation
This removes the .ioctl file operation from all the remaining users that are in today's linux-next tree. I'd like to have this added to linux-next to make sure we don't get any new users and we can seamlessly apply the final patches for this in 2.6.36. The intention behind removing the .ioctl operation is to... 3 Jul 2010 18:59

[PATCH v4 0/2] hwmon: Add support for W83667HG-B to w83627ehf driver.
The following patch series adds support for W83667HG-B to the w83627ehf driver. The first patch makes generic changes to the driver, the second patch adds support for W83667HG-B. Key relevant difference between W83667HG and W83667HG-B are the Chip ID as well as fan output and step output register addresses. Tho... 3 Jul 2010 18:59

[PATCH 8/8] BKL: introduce CONFIG_BKL.
To make it possible to build a kernel without the big kernel lock, we need to make sure we don't build any code that still uses it, so disable the options in Kconfig. Most of the v4l, drm and oss drivers still need it too, but their respective top-level interfaces get disabled here, so we don't need to list the... 3 Jul 2010 18:59

[PATCH 7/8] soundcore_open: Reduce the area BKL coverage
From: John Kacur <jkacur(a)redhat.com> Most of this function is protected by the sound_loader_lock. We can push down the BKL to this call out err = file->f_op->open(inode,file); In order to build the sound core without the BKL, we will need to push the lock_kernel() call into the ~20 device drivers that register... 3 Jul 2010 18:59

[PATCH 2/8] init: remove the BKL from startup code
I have shown by code review that no driver takes the BKL at init time any more, so whatever the init code was locking against is no longer there and it is now safe to remove the BKL there.

[PATCH 3/8] hpet: kill BKL, add compat_ioctl
hpet uses the big kernel lock in its ioctl and open functions. Replace this with a private mutex to be sure. Since we're already touching the ioctl function, add the compat_ioctl version as well -- all commands except HPET_INFO are compatible and that one is easy to add.

[PATCH 5/8] dasd: no need for BKL in ioctl
