2010-10-25ARM: S5PV210: Add struct clk_ops for clk_fout_apllJaecheol Lee
Current fout_apll has fixed rate value. So CPUFREQ driver gets incorrect value when finding current CPU frequency. Because some operation level need to change APLL. Added get_rate function for fout_apll can give correct frequency value when calling get_rate function.

2010-10-25x86/oprofile: Fix uninitialized variable use in debug printkIngo Molnar
Stephen Rothwell reported this build warning: arch/x86/oprofile/op_model_amd.c: In function 'ibs_eilvt_valid': arch/x86/oprofile/op_model_amd.c:289: warning: 'offset' may be used uninitialized in this function And correctly observed that indeed the variable is used uninitialized in this function. The result of this bug can be a debug printk with a bogus value. Also fix a few more small details that made this function hard to read and which probably contributed to the bug being introduced to begin with: - Use more symmetric error conditions - Remove the !0 obfuscation - Add newlines to the printk output - Remove bogus linebreaks in printk strings and elsewhere Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Robert Richter <robert.richter@amd.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> LKML-Reference: <20101025115736.41d51abe.sfr@canb.auug.org.au> Signed-off-by: Ingo Molnar <mingo@elte.hu>

Add platform data, necessary to use Sony IMX074 camera sensor with AP4EVB. Note: this does not work reliably without an API to reserve contiguous and coherent memory for V4L DMA buffers.

2010-10-24KVM: x86: TSC catchup modeZachary Amsden
Negate the effects of AN TYM spell while kvm thread is preempted by tracking conversion factor to the highest TSC rate and catching the TSC up when it has fallen behind the kernel view of time. Note that once triggered, we don't turn off catchup mode. A slightly more clever version of this is possible, which only does catchup when TSC rate drops, and which specifically targets only CPUs with broken TSC, but since these all are considered unstable_tsc(), this patch covers all necessary cases.

2010-10-24KVM: x86: Make math work for other scalesZachary Amsden
The math in kvm_get_time_scale relies on the fact that NSEC_PER_SEC < 2^32. To use the same function to compute arbitrary time scales, we must extend the first reduction step to shrink the base rate to a 32-bit value, and possibly reduce the scaled rate into a 32-bit as well. Note we must take care to avoid an arithmetic overflow when scaling up the tps32 value (this could not happen with the fixed scaled value of NSEC_PER_SEC, but can happen with scaled rates above 2^31.
