Only run vtime_user_enter, vtime_user_exit, and the user enter & exit
trace points when we are entering or exiting user state, respectively.
The KVM code in guest_enter and guest_exit already take care of calling
vtime_guest_enter and vtime_guest_exit, respectively.

Current context tracking symbols are designed to express living state.
As such they are prefixed with "IN_": IN_USER, IN_KERNEL.
Now we are going to use these symbols to also express state transitions
such as context_tracking_enter(IN_USER) or context_tracking_exit(IN_USER).
But while the "IN_"

The host kernel is not doing anything while the CPU is executing
a KVM guest VCPU, so it can be marked as being in an extended
quiescent state, identical to that used when running user space
code.
The only exception to that rule is when the host handles an
interrupt, which is

The comment in the signal code says that apps can save/restore other
segments on their own. It's true that apps can *save* SS on their
own, but there's no way for apps to restore it: SYSCALL effectively
resets SS to __USER_DS, so any value that user code tries to load
into SS gets lost on entry

As far as I can tell, these fields have been set to zero on save and
ignored on restore since Linux was imported into git. Rename them
'__pad1' and '__pad2' to avoid confusion and to allow them to be
recycled some day.
I'm intentionally avoiding calling either of them __pad0: the field

Patch 1 is IMO a bug fix.
Patch 2 is a cleanup and avoids some confusion. It's also sort of an
API break (no ABI change) because it removes a struct field. But that
struct field has never done anything at all as far as I can tell.
AFAICT this series got bogged down in discussion about patch 2

Hi,
I'm resending the patch from here:
