Subject: Re: [PATCH 2/8] x86/msr: Switch all callers of rdmsrq_on_cpu() to use rdmsr_on_cpu()

So instead of:
x86/msr: Switch rdmsr_on_cpu() to return a 64-bit quantity
x86/msr: Switch all callers of rdmsrq_on_cpu() to use rdmsr_on_cpu()
We want something like this:
x86/msr: Convert rdmsrl_on_cpu() users to rdmsrq_on_cpu()
x86/msr: Drop the rdmsrl_on_cpu() alias to rdmsrq_on_cpu()
x86/msr: Switch all callers of rdmsr_on_cpu() to use rdmsrq_on_cpu()
x86/msr: Drop the obsolete rdmsr_on_cpu() API
Patch #1-#2 can be a single patch I guess, since there's only
a single user.
Thanks,
Ingo
