x86: avoid annoying GCC 12 bounds check in curcpu() and curlwp().

these functions read %gs and return an pointer at an offset from this
value (the current cpu, or lwp pointers), and GCC is complaining that
they're accessing a array cpu_info[0] (ie, zero length, no storage.)

several attempts to workaround it have failed, and because of the
asm volatile nature of this, it seems very unlikely a compiler would
take this and do something wrong with it.

i386: Make curlwp and curcpu() flushable.

The only effect of the `volatile' qualifier on an asm block with
outputs is to force the instructions to appear in the generated code,
even if the outputs end up being unused.  Since these instructions
have no (architectural) side effects -- provided %fs is set
correctly, which must be the case here -- there's no need for the
volatile qualifier, so nix it.

On Xen, copy just the bits we need from the trapframe for hardclock(9)
and statclock(9).

Current, the macros that use the trapframe are:
CLKF_USERMODE()
CLKF_PC()
CLKF_INTR()

Of these, CLKF_INTR() already ignores the frame and uses the ci_idepth
variable to do its job.

Convert the two remaining ones to do this, but only for XEN.

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.

Add support for kernel preeemption to the i386 and amd64 ports. Notes:

- I have seen one isolated panic in the x86 pmap, but otherwise i386
  seems stable with preemption enabled.

- amd64 is missing the FPU handling changes and it's not yet safe to
  enable it there.

- The usual level for kern.sched.kpreempt_pri will be 128 once enabled
  by default. For testing, setting it to 0 helps to shake out bugs.

Split off the Transmeta Crusoe Longrun code into its own file, that
way identcpu.c and machdep.c are not cluttered with foreign code.

The driver is built by default as before, but the sysctl subtree will
only be created if longrun is detected and not always as the old code
did. This matches what the FreeBSD code does.

Ok by christos@.

Match delay/DELAY on x86 with delay(9). It takes an unsigned int as
argument. Use this and replace the inline assembly (mul + div using the
64bit intermediate result) with normal 32bit multiplication and
division. The compiler can turn the division into a multiplication and
shift, making it even cheaper then the original assembly. For extreme
long delays, just use 64bit arithmetic.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

x86 changes for pcc and LKMs.

- Replace most inline assembly with proper functions. As a side effect
  this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
  smaller amount. Nearly all of the inlines did something slow, or something
  that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
  In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.

- Add ci_cpumask and use in preference to (1 << ci_cpuid). Some processors
  are bad at shifting by non-constant amounts.
- pmap_tlb_shootdown() must be called with preemption disabled.
- Defer waiting for tlb shootdown to complete after kenter_pa()/kremove().
  Spin in pmap_update() and in pmap_detactivate(), in case the LWP has been
  preempted
- When preparing to send a multicast shootdown IPI, avoid scanning the list
  of CPUs if the pmap's bitmask indicates that it's only active locally.

- There are now 8 interrupt priority levels, half of which are softints.
  Update intrdefs.h to match.

- Remove the horrible ci_self150 hack that I introduced.
- Overhaul how TLB shootdown is performed. Inspired by a similar change in

There's no need to run est_init or k8_powernow_init on each CPU.
Just run it once (in the first cpu probed) with the RUN_ONCE(9)

Change the argument of est_init and k8_powernow_init to void, we don't
need cpu_info * anymore.

clean up how cpus and ioapics are attached at the mainbus:
Seperate "cpubus" and "ioapicbus" -- while they share a common "address
space" (the apic id), the kernel doesn't use this fact. There are different
data passed to cpus and apics, which caused some ugly polymorphism. This
also saves the special "submatch" functions needed to distingush cpus
and ioapics for autoconf. (And it makes that "apid" locators wired
in the kernel configuration are honored now; this allows one to dumb down
an mp box to singleprocessor by userconfig.)
Print "apid" locators in the buses "print" function "as everyone does",
so the per-port cpu drivers don't need to do it.
Being here, constify "struct cpu_functions" and g/c the unused MP_PICMODE
flag.

If running on a PPro or later, at boot patch in versions of spllower() and
similar that use cmpxchg8b instead of cli/sti. Cuts the clock cycles for
splx() by a factor of ~6 on the P4, and ~3 on the PIII when bracketed by
serializing instructions (and hopefully more when not).

Integrate support for Enhanced SpeedStep Technology (est) that
Michael Eriksson posted to port-i386 on 20031102, with various
modifications by me to work in the new sysctl(9) framework.

The code is enabled with 'options ENHANCED_SPEEDSTEP', and if
the CPU supports EST the following sysctl(8) nodes appear
(with the values that a Dell Inspiron 8600 + WUXGA with a
1.4GHz Pentium M CPU supports):
	machdep.est.cpu_brand = Intel(R) Pentium(R) M processor 1400MHz
	machdep.est.frequency.target = 1400
	machdep.est.frequency.current = 1400
	machdep.est.frequency.available = 1400 1200 1000 800 600

If EST support isn't available, the "machdep.est" sysctl sub-MIB
is not created.

Once we have a more general "CPU frequency" control API we can
migrate this code to using that.

Thanks to Michael Erikkson for providing this code!

Process and lwp exit path always executes lwp_exit2() now and cpu_exit()

Replace the traditional buffer memory management -- based on fixed per buffer
virtual memory reservation and a private pool of memory pages -- by a scheme
based on memory pools.

This allows better utilization of memory because buffers can now be allocated
with a granularity finer than the system's native page size (useful for
filesystems with e.g. 1k or 2k fragment sizes).  It also avoids fragmentation
of virtual to physical memory mappings (due to the former fixed virtual
address reservation) resulting in better utilization of MMU resources on some
platforms.  Finally, the scheme is more flexible by allowing run-time decisions
on the amount of memory to be used for buffers.

On the other hand, the effectiveness of the LRU queue for buffer recycling
may be somewhat reduced compared to the traditional method since, due to the
nature of the pool based memory allocation, the actual least recently used
buffer may release its memory to a pool different from the one needed by a
newly allocated buffer. However, this effect will kick in only if the
system is under memory pressure.

New interrupt code. The basic idea behind it is to hide the differences
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.

The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.

Add options TRAPLOG:

When enabled, each cpu gets a ring buffer; on every trap entry, we add
an entry to the trap log using the new locore "TLOG" macro.  Somewhat

what was going on as we were spiralling in...

XXX currently depends on various intel MSR's to record the low order

Implement MP-synchronzed microtime(), based on Jason Thorpe's port of
Dave Mills's cycle-counter-based microtime.

XXX We need to figure out how to deal with processors where the cycle
counter speed varies.  We don't have a whole lot of alternatives; we
could only use this on multiprocessors, which are less likely to
throttle the clock to save power.

The local apic timer runs at a fixed frequency, but it's
count-down-to-zero, not the count-up-forever type of timer which the
Mills code expects.

This also does not solve the problem of microtime on 486-based
multiprocessors..

Significant rewrite of slave CPU attach and initialization, centering
on identifycpu() and spreading outward.

Separate feature probes (cpuid invocation), which runs on the cpu
being attached, from the display of this information, which runs on
the boot cpu; remove some of the probe code from locore as it doesn't
need to run that early.

We now spin up secondary cpu's during cpu_attach, have them do a cpu
feature probe, and then have them spin waiting for a "go" signal.

We no longer pay attention to the cpu signature and cpuid features
reported by the MP BIOS since those are known to be truncated for at
least some bioses.

We now do npx initialization (including FDIV bug detection) on all
cpus.

XXX Change some of the cyrix bug workarounds to fit the new
identifycpu() system; this is untested.

Mostly fix cpu identification:
 - move globals which contain per-cpu state into cpu_info.
 - fix cache size probing to work off of cpu_info rather than globals
 - print out itlb/dtlb sizes
 - add a few more cache identifiers from the latest version of AP-485

cpu timing, cache probing, and processor serial number lookup still
happens only on the main cpu; this needs to be restructured; mark what
code needs to move into per-cpu probe code.

While we're here, eradicate "cpu_info_store" in favor of "cpu_info_primary".

Use this in i386 to remove profiling code from the normal userret() path.

 - turn on local apic clock in cpu_hatch()
 - load the right gdt descriptor in cpu_hatch()
 - return from cpu_hatch() instead of spinning there; current
mptramp code will spin; future code will jump to idle loop.

First sweep at scheduler state cleanup.  Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

Changes for NKPDE calculation from cgd.

- New variables: biosextmem, biosbasemem, nkpde
- Above can be set by using the options BIOSEXTMEM, BIOSBASEMEM,
  and NKPDE respectively (EXTMEM_SIZE is now called BIOSEXTMEM).
  When preset this way, they won't be filled in / calculated.
- Readable by sysctl using machdep.nkpde, machdep.biosbasemem
  and machdep.biosextmem.
- nkpde is calculated as:

	min(NKPDE_MAX, NKPDE_BASE + (biosextmem >> 10) * NKPDE_SCALE)

  Where NKPDE_MAX is 31, NKPDE_BASE is 4, NKPDE_SCALE = 1.
