Use the inlines; it is actually fine, since the compiler drops the inlines
if the caller is kmsan-instrumented, forcing a white-listing of the memory

Add support for Kernel Memory Sanitizer (kMSan). It detects uninitialized
memory used by the kernel at run time, and just like kASan and kCSan, it
is an excellent feature. It has already detected 38 uninitialized variables
in the kernel during my testing, which I have since discreetly fixed.

We use two shadows:
 - "shad", to track uninitialized memory with a bit granularity (1:1).
   Each bit set to 1 in the shad corresponds to one uninitialized bit of
   real kernel memory.
 - "orig", to track the origin of the memory with a 4-byte granularity
   (1:1). Each uint32_t cell in the orig indicates the origin of the
   associated uint32_t of real kernel memory.

The memory consumption of these shadows is consequent, so at least 4GB of
RAM is recommended to run kMSan.

The compiler inserts calls to specific __msan_* functions on each memory
access, to manage both the shad and the orig and detect uninitialized
memory accesses that change the execution flow (like an "if" on an
uninitialized variable).

We mark as uninit several types of memory buffers (stack, pools, kmem,
malloc, uvm_km), and check each buffer passed to copyout, copyoutstr,
bwrite, if_transmit_lock and DMA operations, to detect uninitialized memory
that leaves the system. This allows us to detect kernel info leaks in a way
that is more efficient and also more user-friendly than KLEAK.

Contrary to kASan, kMSan requires comprehensive coverage, ie we cannot
tolerate having one non-instrumented function, because this could cause
false positives. kMSan cannot instrument ASM functions, so I converted
most of them to __asm__ inlines, which kMSan is able to instrument. Those
that remain receive special treatment.

Contrary to kASan again, kMSan uses a TLS, so we must context-switch this
TLS during interrupts. We use different contexts depending on the interrupt
level.

The orig tracks precisely the origin of a buffer. We use a special encoding
for the orig values, and pack together in each uint32_t cell of the orig:
 - a code designating the type of memory (Stack, Pool, etc), and
 - a compressed pointer, which points either (1) to a string containing
   the name of the variable associated with the cell, or (2) to an area
   in the kernel .text section which we resolve to a symbol name + offset.

This encoding allows us not to consume extra memory for associating
information with each cell, and produces a precise output, that can tell
for example the name of an uninitialized variable on the stack, the
function in which it was pushed on the stack, and the function where we
accessed this uninitialized variable.

kMSan is available with LLVM, but not with GCC.

The code is organized in a way that is similar to kASan and kCSan, so it
means that other architectures than amd64 can be supported.

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.

Make cpu_idle a macro calling a function pointer on x86.
Select the Xen idle routine for Xen, mwait if supported by the CPU and
it is not AMD and halt otherwise. As reported by Christoph Egger,
AMD Barcelona keeps the CPU in C0 state with MWAIT, contrary to HLT,
which uses C1 and therefore much less power.

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.

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.

Mathieu Ropert in 2006.
DomU-only for now. An INSTALL_XEN3_DOMU kernel with a ramdisk will boot to
sysinst if you're lucky. Often it panics because a runable LWP has
a NULL stack (really, it's all of l->l_addr which is has been zeroed out
while the process was on the queue !)
TODO:
- bug fixes :)
- Most of the xpq_* functions should be shared with xen/i386
- The xen/i386 assembly bootstrap code should be remplaced with the C
  version in xenamd64/amd64/xpmap.c
- see if a config(5) trick could allow to merge xenamd64 back to xen or amd64.

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.

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.

delay() is gone, so don't declare it.  That way other parts of code that
use a variable named delay (say, netinet6/in6.c) won't shadow something
that doesn't exist anyway.

Change all archs that did:

#define clockframe somethingelse

to:

struct clockframe {
	struct somethingelse cf_se;
};

and change access macros accordingly.

That means that, at least for that very issue, things will not go
ka-boomy if you don't have the actual definition of struct clockframe
before including systm.h.

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.

Rename the x86_64 port to amd64, as this is the actual name used for
the processor family now. x86_64 is kept as the MACHINE_ARCH value,
since it's already widely used (by e.g. the toolchain, etc), and
by other operating systems.
