[PATCH v2] procfs: Push down the bkl from ioctl
Push down the bkl from procfs's ioctl main handler to its users. Only three procfs users implement an ioctl (non unlocked) handler.

[PATCH 2/2] ibft: For UEFI machines actually do scan ACPI for iBFT.
For machines with IBFT 1.03 do scan the ACPI table for 'iBFT' or for 'IBFT'. If the machine is in UEFI mode, only do the ACPI table scan. For all other machines (pre IBFT 1.03) do a memory scan if not found in the ACPI tables.

[PATCH 03/12] eeprom_read()/eeprom_write() should update ppos instead of file->f_pos
eeprom_read()/eeprom_write() modify file->f_pos directly instead of the ppos given. The VFS later updates the file->f_pos and overwrites it with the unchanged value of ppos. Since nothing touches the struct file in eeprom_read()/eeprom_write() now, the on stack allocated struct file in eeprom_read_buf()/eeprom_writ... 9 Apr 2010 11:08

[PATCH 05/12] mISDN: Remove unnecessary test on f_pos
This test is not doing anything since it is always false if the mISDN_read() is called from vfs_read(). Besides that the driver uses nonseekable_open() and is not using off or file->f_pos anywhere.
