    x86/Viridian: don't depend on undefined register state
    
    The high halves of all GPRs are undefined in 32-bit and compat modes,
    and the dependency is being obfuscated by our structure field names not
    matching architectural register names (it was actually while putting
    together a patch to correct this when I noticed the issue here).
    
    For consistency also use the architecturally correct names on the
    output side.

    x86emul: fix pushing of selector registers
    
    Both explicit PUSH and far CALL currently push unrelated data (the
    segment attributes word) in the high half (attributes and limit in the
    64-bit case in the high 48 bits) instead of zero. To avoid having to
    apply this and further changes in multiple places, also fold the two
    (respectively) far call/jmp instances into one.

    xen/trace: Fix trace metadata page count calculation (revert fbf96e6)
    
    Changeset fbf96e6, "xentrace: correct formula to calculate
    t_info_pages", broke the trace metadata page count calculation, by
    mistaking t_info_first_offset as denominated in bytes, when in fact it
    is denominated in words (uint32_t).
    
    Effectively revert that change, and put a comment there to reduce the
    chance that someone will make that mistake in the future.

    x86: defer not-present segment checks
    
    Following on from commits 5602e74c60 ("x86emul: correct loading of
    %ss") and bdb860d01c ("x86/HVM: correct segment register loading during
    task switch") the point of the non-.present checks needs to be refined:
    #NP (and its #SS companion), other than suggested by the various
    instruction pages in Intel's SDM, gets checked for only after all type
    and permission checks. The only checks getting done even later are the
    long mode specific ones for system descriptors (which we don't support
    yet) and 64-bit code segments (i.e. anything touching other than the
    attribute byte).

    x86/hvm: Correct the position of the %cs L/D checks
    
    Contrary to the description in the software manuals, in Long Mode, attempts 
to
    load %cs check that D is not set in combination with L before the present 
flag
    is checked.
    
    This can be observed because the L/D check fails with #GP before the 
presence
    check failes with #NP.
    
    This change partially reverts c/s 78ff18c90 "x86: defer not-present segment
    checks", taking it back to how it was in the v1 submission.

    xen: credit1: return the 'time remaining to the limit' as next timeslice.
    
    If vcpu x has run for 200us, and sched_ratelimit_us is
    1000us, continue running x _but_ return 1000us-200us as
    the next time slice. This way, next scheduling point will
    happen in 800us, i.e., exactly at the point when x crosses
    the threshold, and can be descheduled (if appropriate).
    
    Right now (without this patch), we're always returning
    sched_ratelimit_us (1000us, in the example above), which
    means we're (potentially) allowing x to run more than
    it should have been able to.
    
    Note that, however, in order to avoid setting timers to very
    short intervals, which is part of the purpose of rate limiting,
    we never use a time slice smaller than a well defined threshold.
    Such threshold (CSCHED_MIN_TIMER defined in this patch) is, in
    general independent from rate limiting, but it looks a good idea
    to set it to the minimum possible ratelimiting value.
