I know it's mildly obvious but could you please add a problem statement
to these changelogs, even if it's just one little sentence?
For some reason, there are some TSC-related functions in the
MSR header even though there is a tsc.h header.
Relocate rdtsc{,_ordered}() and subsequently remove the
inclusion of <asm/msr.h> in <asm/tsc.h>. Consequently,
<asm/msr.h> must be included in several source files that
previously did not require it.
But I agree with the concept, so with this fixed:
