Hopefully fix some problems seen with MP support on non-x86, in particular
where curcpu() is defined as curlwp->l_cpu:

- mi_switch(): undo the ~2007ish optimisation to unlock curlwp before
  calling cpu_switchto().  It's not safe to let other actors mess with the
  LWP (in particular l->l_cpu) while it's still context switching.  This
  removes l->l_ctxswtch.

- Move the LP_RUNNING flag into l->l_flag and rename to LW_RUNNING since
  it's now covered by the LWP's lock.

- Ditch lwp_exit_switchaway() and just call mi_switch() instead.  Everything
  is in cache anyway so it wasn't buying much by trying to avoid saving old
  state.  This means cpu_switchto() will never be called with prevlwp ==
  NULL.

- Remove some KERNEL_LOCK handling which hasn't been needed for years.

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.

Excise XEN specific code out of x86/x86/intr.c into xen/x86/xen_intr.c

While at it, separate the source function tracking so that the interrupt
paths are truly independant.

Use weak symbol exporting to provision for future PVHVM co-existence
of both files, but with independant paths. Introduce assembler code
such that in a unified scenario, native interrupts get first priority
in spllower(), followed by XEN event callbacks. IPL management and
semantics are unchanged - native handlers and xen callbacks are
expected to maintain their ipl related semantics.

In summary, after this commit, native and XEN now have completely
unrelated interrupt handling mechanisms, including
intr_establish_xname() and assembler stubs and intr handler
management.

Happy Christmas!

Explicitly unpoison the stack when entering a softint.

Softints are the only place where we "discard" a part of the stack: we may
have left the thread without allowing the asan instrumentation to clear
the poison, and in this case, we can get false positives when we hit a
poisoned area of the stack while executing another handler within the same
softint thread.

(I was actually getting a rare false positive in ip6intr.)

Drop NENTRY() from the x86 kernels, use ENTRY(). With PMCs (and other hardware
tracing facilities) we have a much better ways of monitoring the CPU activity

Also I think GPROF has never worked, because the 'start' functions of both
i386 and amd64 use ENTRY(), and it would have caused a function call while the
kernel was not yet relocated.

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.

softintr_ret keeps the IPL raised until returning to doreti/splx in order
to avoid recursing. To keep the IPL raised it adjusts ci_mtx_oldspl before
dropping curlwp->l_mutex. That's not safe if the current CPU holds more than
one spin mutex, and can lead to "WARNING: SPL NOT LOWERED...". Fix it.

- When computing the TSC frequency, call i8254_delay() and not DELAY().
- Use atomics to adjust the pmap reference count, instead of taking locks.
- Implement I386_{SET,GET}_{FS,GS}BASE, allowing %fs and %gs to be used
  as per-thread registers. This is compatible with FreeBSD.
- Run patches after we have attached CPUs, since we then know if the
  system is uniprocessor or not. Eliminates a lot of #ifdef MULTIPROCESSOR
  and makes running MP kernels on UP systems cheaper.
- Patch out many of the 'lock' prefixes to nops if uniprocessor.
- Do a wbinvd after patching to ensure that the trace/instruction cache
  is up to date.

- define and use pmap_pa2pte()/pmap_pte2pa() to read/write PTE entries
- define pmap_pte_flush() which is a nop in x86 case, and flush the
  MMUops queue in the Xen case

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.

- Restore previous locking behaviour in cpu_switch(). Seems to fix what
  look like corrupted trap frames.

Updaing ci_ilevel and testing ci_ipending must be done with all interrupts
off, or priority inversion can occur, which can lead to IPI deadlocks.
Leaves interrupts off for a bit longer, sadly, but with no noticeable
effects on the systems I tested on.

Pass pointers to frames from assembly, do not use the 'frame on stack
as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions
about the stack that will not be true. Costs 2 instructions per trap/syscall
on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64,
2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better
optimization (it'd better..)

While here, make amd64 compile again by using subr_mbr_disk.c

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.
