Subject: [PATCH] Quieten hrtimer printk: "Switched to high resolution mode .."

Change the hrtimer printk "Switched to high resolution mode .." to
be KERN_DEBUG, rather than KERN_INFO. If users need to see this they
can pass "loglevel" or "debug" on the command line, or check dmesg.

Any objections? It gets a little repetitive, eg:

Switched to high resolution mode on CPU 0
Switched to high resolution mode on CPU 17
Switched to high resolution mode on CPU 10
Switched to high resolution mode on CPU 2
Switched to high resolution mode on CPU 7
Switched to high resolution mode on CPU 11
Switched to high resolution mode on CPU 3
Switched to high resolution mode on CPU 8
Switched to high resolution mode on CPU 12
Switched to high resolution mode on CPU 1
Switched to high resolution mode on CPU 4
Switched to high resolution mode on CPU 5
Switched to high resolution mode on CPU 13
Switched to high resolution mode on CPU 14
Switched to high resolution mode on CPU 15
Switched to high resolution mode on CPU 9
Switched to high resolution mode on CPU 6
Switched to high resolution mode on CPU 16

cheers
