Gayatri,

If there is going to be PMC subfolder, then yes of course amd-pmc.c 
should move into it too.

Are you also thinking to move uPEP code from drivers/acpi/x86/s2idle.c 
into the PMC drivers?  Or do you have some suggestions on what code 
could be shared between AMD and Intel PMC drivers?

Thanks,
