Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use. Noted in 'next' by Stephen Rothwell.

+ README for btmrvl driver
+=======================================================================
+
+
+All commands are used via debugfs interface.
+
+=====================
+Set/get driver configurations:
+
+Path: /debug/btmrvl/config/
+
+gpiogap=[n]
+hscfgcmd
+ These commands are used to configure the host sleep parameters.
+ bit 8:0 -- Gap
+ bit 16:8 -- GPIO
+
+ where GPIO is the pin number of GPIO used to wake up the host.
+ It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface
+ wakeup will be used instead).
+
+ where Gap is the gap in milli seconds between wakeup signal and
+ wakeup event, or 0xff for special host sleep setting.
+
+ Usage:
+ # Use SDIO interface to wake up the host and set GAP to 0x80:
+ echo 0xff80 > /debug/btmrvl/config/gpiogap
+ echo 1 > /debug/btmrvl/config/hscfgcmd
+
+ # Use GPIO pin #3 to wake up the host and set GAP to 0xff:
+ echo 0x03ff > /debug/btmrvl/config/gpiogap
+ echo 1 > /debug/btmrvl/config/hscfgcmd
+
+psmode=[n]
+pscmd
+ These commands are used to enable/disable auto sleep mode
+
+ where the option is:
+ 1 -- Enable auto sleep mode
+ 0 -- Disable auto sleep mode
+
+ Usage:
+ # Enable auto sleep mode
+ echo 1 > /debug/btmrvl/config/psmode
+ echo 1 > /debug/btmrvl/config/pscmd
+
+ # Disable auto sleep mode
+ echo 0 > /debug/btmrvl/config/psmode

+
+
+hsmode=[n]
+hscmd
+ These commands are used to enable host sleep or wake up firmware
+
+ where the option is:
+ 1 -- Enable host sleep
+ 0 -- Wake up firmware
+
+ Usage:
+ # Enable host sleep
+ echo 1 > /debug/btmrvl/config/hsmode
+ echo 1 > /debug/btmrvl/config/hscmd
+
+ # Wake up firmware
+ echo 0 > /debug/btmrvl/config/hsmode
+ echo 1 > /debug/btmrvl/config/hscmd

+
+======================
+Get driver status:
+
+Path: /debug/btmrvl/status/
+
+Usage:
+ cat /debug/btmrvl/status/<args>
+
+where the args are:
+
+curpsmode
+ This command displays current auto sleep status.
+
+psstate
+ This command display the power save state.
+
+hsstate
+ This command display the host sleep state.
+
+txdnldrdy
+ This command displays the value of Tx download ready flag.
+
+
+=====================
+
+Use hcitool to issue raw hci command, refer to hcitool manual
+
+ Usage: Hcitool cmd <ogf> <ocf> [Parameters]
+
+ Interface Control Command
+ hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00 --Enable All interface

+When: 2.6.34
+
+Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the
+ prism54 wireless driver. After Intersil stopped selling these
+ devices in preference for the newer more flexible SoftMAC devices
+ a SoftMAC device driver was required and prism54 did not support
+ them. The p54pci driver now exists and has been present in the kernel for
+ a while. This driver supports both SoftMAC devices and FullMAC devices.
+ The main difference between these devices was the amount of memory which
+ could be used for the firmware. The SoftMAC devices support a smaller
+ amount of memory. Because of this the SoftMAC firmware fits into FullMAC
+ devices's memory. p54pci supports not only PCI / Cardbus but also USB
+ and SPI. Since p54pci supports all devices prism54 supports
+ you will have a conflict. I'm not quite sure how distributions are
+ handling this conflict right now. prism54 was kept around due to
+ claims users may experience issues when using the SoftMAC driver.
+ Time has passed users have not reported issues. If you use prism54
+ and for whatever reason you cannot use p54pci please let us know!
+ E-mail us at: linux-wireless@vger.kernel.org
