Before this change, successful microcode uploads clearly
indicate that it was done:
microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x1a
microcode: CPU1 updated to revision 0x29, date = 2013-06-12
whereas if microcode was not uploaded, it is not clear why:
microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x29
(nothing more)
So, what was it? No microcode file? No microcode for this sig/pf?
CPU already has microcode with this (or newer) revision?
In practice, it means that I heed to ask people to provide me
with more information ("do you have microcode package installed?
which version is it?").
This change upgrades existing message from pr_debug to pr_info,
which covers "no microcode file" case:
microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x29
microcode: data file intel-ucode/06-2a-07 load failed
