entry->proc_fops is a pointer to struct file_operations. When we
call create_proc_entry(...), it pointis to proc_file_operations,
deep in fs/proc/generic.c. By adding a 'poll' member to this struct
we effectively force the 'poll' member on every file in /proc,
which is wrong (they all fail select(...) calls).
This patch changes a copy of entry->proc_fops and reassigns it rather
than changing the original member.

uinput_alloc_device() is supposed to return the number of bytes read,
the value is returned to uinput_write() and from there to userspace. If
EV_ABS is set then it returns the value from uinput_validate_absbits()
instead, which is zero when everything is ok instead of the count.

I have an Ahtec laptop with a ALPS GlidePoint device, with 4 buttons.
With Linux hernel 2.6.12rc4 and rc5 I'm unable to use the vertical
scroll buttons (BACK and FORWARD).
BACK gets detected as BTN_MIDDLE and FORWARD is undetected.
I've modified the drivers/input/mouse/alps.c from 2.6.12rc5 and now it
works fine!

[PATCH] [4/5] ondemand governor automatic downscaling
Here is a change of policy for the ondemand governor. The modification
concerns the frequency downscaling. Instead of decreasing to a lower
frequency when the CPU usage is under 20%, this new policy automatically
scales to the optimal frequency. The optimal frequency being the lowest
frequency which provides enough power to not trigger the upscaling policy.

A new cpufreq module, based on the ondemand one with my additional patches
just posted. This one is more suitable for battery environments where its
probably more appealing to have the cpu freq gracefully increase and decrease
rather than flip between the min and max freq's.
N.B. Bruno Ducrot pointed out that the amd64's "do have unacceptable latency
between min and max freq transition, due to the step-by-step requirements
(200MHz IIRC)"; so AMD64 users would probably benefit from this too.

Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu().
It is possible that the bootcode may be loading code from nvram during
this call and stopping the cpu without getting the lock may cause
uncompleted nvram data to be left in the nvram data register. Subsequent
calls to read/write nvram data will fail.
