x86/kernel: Mark expected switch-case fall-throughs
In preparation to enable -Wimplicit-fallthrough by default, mark switch-case statements where fall-through is intentional, explicitly in order to fix a couple of -Wimplicit-fallthrough warnings. Warning level 3 was used: -Wimplicit-fallthrough=3. [ bp: Massasge and trim commit message. ] Signed-off-by: Gustavo A. R.
