[ Upstream commit 04507c0a9385cc8280f794a36bfff567c8cc1042 ] To set frequency on specific cpus using cpupower, following syntax can be used : cpupower -c #i frequency-set -f #f -r While setting frequency using cpupower frequency-set command, if we use '-r' option, it is expected to set frequency for all cpus related to cpu #i. But it is observed to be missing the last cpu in related cpu list. This patch fixes the problem.

commit d8eabc37310a92df40d07c5a8afc53cebf996716 upstream Greg pointed out that speculation related bit defines are using (1 << N) format instead of BIT(N). Aside of that (1 << N) is wrong as it should use 1UL at least. Clean it up.

Going primarily by:
https://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors
with additional information gleaned from other related pages; notably:
- Bonnell shrink was called Saltwell
- Moorefield is the Merriefield refresh which makes it Airmont
The general naming scheme is: FAM6_ATOM_UARCH_SOCTYPE

[ Upstream commit f69ffc5d3db8f1f03fd6d1df5930f9a1fbd787b6 ] cpupower crashes on VMWare guests. The guests have the AMD PStateDef MSR (0xC0010064 + state number) set to zero. As a result fid and did are zero and the crash occurs because of a divide by zero (cof = fid/did). This can be prevented by checking the enable bit in the PStateDef MSR before calculating cof. By doing this the value of pstate[i] remains zero and the value can be tested before displaying the active Pstates. Check the enable bit in the PstateDef register for all supported families and only print out enabled Pstates.

Almost all files in the kernel are either plain text or UTF-8 encoded. A couple however are ISO_8859-1, usually just a few characters in a C comments, for historic reasons.
