[Bluetooth] Dynamic allocation of the RFCOMM TTY devices
Only allocate the RFCOMM TTY devices when they are really in use. This
prevents the system from calling hotplug and udev 256 times to create or
remove every device node. In fact this makes the loading and unloading
of the RFCOMM module much faster.

[Bluetooth] Send HCI_Reset for some Broadcom dongles
This patch introduces a quirk flag for sending the HCI_Reset command. In
general the HCI_Reset is not needed, but some Broadcom dongles uses this
reset command to switch from HID to HCI mode. And it is not safe to send
the HCI_Reset to every Bluetooth device, because the CSR firmware prior
HCI 12.x will reset the host transport and this is wrong according to the
Bluetooth specification.

[ARM PATCH] 1757/1: Allow building of LE kernels with BE-default toolchain
Patch from Deepak Saxena
The ARM makefile currently assumes that the compiler being used
defaults to little-endian builds unless the big-endian options
are provided. This may not always be the case (my toolchains default
to BE since that's what I mostly work with) so this patch forces
endianess options to be passed to the toolchain. W/O this,
building without CONFIG_CPU_BIG_ENDIAN on a big-endian toolchain
will still result in a big-endian kernel.

[PATCH] d_alloc_root() fixes: gadgetfs
gatgetfs fill_super:
- double-free of inode on last two failure exits
- leak on the last failure exit
- touching addresses near 0 on last two failure exits
New revision of the Sigmatel irda driver. This version has much
better performance and doesn't drop frames in FIR mode.
Tested with both UHCI and EHCI/OHCI against nsc-ircc on laptop.
Thanks to Martin for additional testing and feedback.
* Receiver:
- changed from interrupt to bulk URB. Queue's one bulk
urb per USB tick (1ms).
- FIR unpack now uses get_unaligned and cpu32_le
instead of explicit shifts
- FIR unpack copies small frames
* Transmitter:
- pack data into io buffer. Since irda is half duplex
can use same buffer for transmit and receive.
- use xchange and wait_event for synchronization
* Other:
- use USB format messages rather than IRDA (ugly)
- clean up USB startup
- reset device on network open to clear up stuck state
- handle FIFO errors
- disconnect cleanup (from viro)
- don't DMA onto stack when reading fifo status
This adds a "timbase" entry in /proc/cpuinfo like p/iSeries that
provides the CPU timebase frequency. It is using by a all sort of
performance analysis tools we are hacking in house.
It also remove a useless bit about the l2 cache that was copied over
from ppc32.
I've had reports of flicker that appear with large (23") flat panels
and radeonfb. From experiments, it appears that forbiding the "odd"
PLL divider values fix it (like it fixes the blur problem on TMDS2).
There should not be anything special with TMDS1 and "odd" PLL values
though, so the problem may be subtly different (a bandwidth problem),
but until I have proper bandwidth calculation and access to this
monitor, the following patch is an acceptable workaround (Odd PLL values
aren't that useful anyway)

[PATCH] oprofile: fix P4 HT msr sharing
From: Philippe Elie <phil.el@wanadoo.fr>
When I debugged P4 ht oprofile a few month ago I noticed that but though it
wasn't a problem... The fix I propose is not completely clean.
With P4 HT we split msr in two subset, one for each logical processor. The
msrs subset used in op_model_p4.c at save and setup point of view are
distinct (*), it means we must serialize setup and save operation else a
logical processor can save some msr value already setup by the other thread
then when oprofile shutdown we restore wrong msrs values.
Nobody noticed the problem because after restoring the msrs we call
enable_lapic_nmi_watchdog() -> setup_p4_watchdog() wich clear all the msrs
but it's a bit fragile. If nmi watchdog is not enabled nothing bad occurs
because the LVTPC remains disabled.
(*) this is done in this way because it allows a lot of simplification in
op_model_p4.c, yes it isn't clean but it's not fixable w/o rewriting 75% of
op_model_p4.c and I think the code will be bigger and more complex.

[PATCH] convert pdflush to kthread
From: Keith Owens <kaos@sgi.com>
New pdflush threads are launched on-demand by pdflush.
It turns out that on some architectures (eg, ia64) a kernel thread inherits
its parent's stack utilisation. So after the thread-launches-a-thread
cycle has progressed sufficiently far we run out of stack space and crash.
Simple fix: convert pdflush to use kthreads. All kthreads are parented by
keventd so there is no stack windup as a result of pdflush launching
pdflush.
Move WATCHDOG_CP1XXX and WATCHDOG_RIO for SPARC64 architecture
from arch/sparc64/Kconfig to drivers/char/watchdog/Kconfig
and made them dependant of WATCHDOG also
