Serialize rdtsc using with lfence, mfence or cpuid to read TSC more precisely.

 x86/x86/tsc.c rev. 1.67 reduced cache problem and got big improvement, but it
 still has room. I measured the effect of lfence, mfence, cpuid and rdtscp.
The impact to TSC skew and/or drift is:

	AMD:   mfence > rdtscp > cpuid > lfence-serialize > lfence = nomodify
	Intel: lfence > rdtscp > cpuid > nomodify

So, mfence is the best on AMD and lfence is the best on Intel. If it has no
SSE2, we can use cpuid.

NOTE:
  - An AMD's document says DE_CFG_LFENCE_SERIALIZE bit can be used for
    serializing, but it's not so good.
  - On Intel i386(not amd64), it seems the improvement is very little.
  - rdtscp instruct can be used as serializing instruction + rdtsc, but
    it's not good as [lm]fence. Both Intel and AMD's document say that
    the latency of rdtscp is bigger than rdtsc, so I suspect the difference
    of the result comes from it.

Fix the TSC timecounter (on the systems I have access to):

- Make the early i8254-based calculation of frequency a bit more accurate.

- Keep track of how far the HPET & TSC advance between HPET attach and
  secondary CPU boot, and use to compute an accurate value before attaching
  the timecounter.  Initial idea from joerg@.

- When determining skew and drift between CPUs, make each measurement 1000
  times and pick the lowest observed value.  Increase the error threshold to
  1000 clock cycles.

- Use the frequency computed on the boot CPU for secondary CPUs too.

- Remove cpu_counter_serializing().

Get TSC frequency from CPUID 0x15 and/or x16 for newer Intel processors.

 - If the max CPUID leaf is >= 0x15, take TSC value from CPUID. Some processors
   can take TSC/core crystal clock ratio but core crystal clock frequency
   can't be taken. Intel SDM give us the values for some processors.
 - It also required to change lapic_per_second to make LAPIC timer correctly.
 - Add new file x86/x86/identcpu_subr.c to share common subroutines between
   kernel and userland. Some code in x86/x86/identcpu.c and cpuctl/arch/i386.c
   will be moved to this file in future.
 - Add comment to clarify.

Fix TSC drift is observed almost every time wrongly.

Ths "TSC drift" in tsc_tc_init() means the cpu_cc_skew delta between
first measurement (in cpu_start_secondary) and second measurement
(in cpu_boot_secondary), that is, the TSC drift is expected to be
almost zero.  However, the second measument in current implementation
is added extra cpu_cc_skew accidentally, so current delta value means
almost cpu_cc_skew wrongly.

tsc_sync_bp and tsc_sync_ap should use rdtsc() to get raw values.

Advised by nonaka@n.o, thanks.

Some CPU have cpu counter (CPUID_TSC is there) but don't handle the
rdmsr instruction (CPUID_MSR is not there).
Introduce a cpu_counter_serializing() function to remplace rdmsr(MSR_TSC)
calls, which does a rdmsr(MSR_TSC) if available and cpu_counter() otherwise.
This makes the cpu counter useable on vortex86 CPUs.

This patch fixes the NX regression issue observed on amd64 kernels, where
per-page execution right was disabled (therefore leading to the inability
of the kernel to detect fraudulent use of memory mappings marked as not
being executable).

- replace cpu_feature and ci_feature_flags variables by cpu_feature and
ci_feat_val arrays. This makes it cleaner and brings kernel code closer
to the design of cpuctl(8). A warning will be raised for each CPU that
does not expose the same features as the Boot Processor (BP).

- the blacklist of CPU features is now a macro defined in the
specialreg.h header, instead of hardcoding it inside MD initialization
code; fix comments.

- replace checks against CPUID_TSC with the cpu_hascounter() function.

- clean up the code in init_x86_64(), as cpu_feature variables are set
inside cpu_probe().

- use cpu_init_msrs() for i386. It will be eventually used later for NX
feature under i386 PAE kernels.

- remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already
performed by cpu_hatch() through cpu_init_msrs().

- remove cpu_signature and feature_flags members from struct mpbios_proc
(they were never used).

This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under
a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines.

XXX Should kernel rev be bumped?

XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.

A fix for failed TSC calibration with the message "ERROR: %lld cycle TSC

On i386, cpu_cc_skew was written out as two 32-bit words. If unlucky, the
boot processor could read the whole 64-bit value after only 32-bits of the
update were written back to main memory.

Improve x86 tsc handling:

- Ditch the cross-CPU calibration stuff. It didn't work properly, and it's
  near impossible to synchronize the CPUs in a running system, because bus
  traffic will interfere with any calibration attempt, messing up the
  timings.

- Only enable the TSC on CPUs where we are sure it does not drift. If we are
  On a known good CPU, give the TSC high timecounter quality, making it the
  default.

- When booting CPUs, detect TSC skew and account for it. Most Intel MP
  systems have synchronized counters, but that need not be true if the
  system has a complicated bus structure. As far as I know, AMD systems
  do not have synchronized TSCs and so we need to handle skew.

- While an AP is waiting to be set running, try and make the TSC drift by
  entering a reduced power state. If we detect drift, ensure that the TSC
  does not get a high timecounter quality. This should not happen and is
  only for safety.

- Make cpu_counter() stuff LKM safe.

Don't pick TSC by default on systems the have ENHANCED_SPEEDSTEP
compiled in. Many TSC's out there are sensitive to cpu frequency
changes. On these platforms we need to use other fixed frequency
timers (e. g. ACPI_PM_TIMER). Maybe we should add detection code
here whether TSC is sensible to cpu frequency changes.
