Revert "x86: Add kthread_fpu_enter/exit support, take two."

kthread_fpu_enter/exit changes broke some hardware, unclear why, to
investigate before fixing and reapplying these changes.

x86: Add kthread_fpu_enter/exit support, take two.

This time, make sure to restore the FPU state when switching to a
kthread in the middle of kthread_fpu_enter/exit.

This adds a single predicted-taken branch for the case of kthreads
that are not in kthread_fpu_enter/exit, so it incurs a penalty only
for threads that actually use it.  Since it avoids FPU state
switching in kthreads that do use the FPU, namely cgd worker threads,
this should be a net performance win on systems using it and have
negligible impact otherwise.

x86: Split most of pmap.h into pmap_private.h or vmparam.h.

This way pmap.h only contains the MD definition of the MI pmap(9)
API, which loads of things in the kernel rely on, so changing x86
pmap internals no longer requires recompiling the entire kernel every
time.

Callers needing these internals must now use machine/pmap_private.h.
Note: This is not x86/pmap_private.h because it contains three parts:

1. CPU-specific (different for i386/amd64) definitions used by...

2. common definitions, including Xenisms like xpmap_ptetomach,
   further used by...

3. more CPU-specific inlines for pmap_pte_* operations

So {amd64,i386}/pmap_private.h defines 1, includes x86/pmap_private.h
for 2, and then defines 3.  Maybe we should split that out into a new
pmap_pte.h to reduce this trouble.

No functional change intended, other than that some .c files must
include machine/pmap_private.h when previously uvm/uvm_pmap.h
polluted the namespace with pmap internals.

Note: This migrates part of i386/pmap.h into i386/vmparam.h --
specifically the parts that are needed for several constants defined
in vmparam.h:

VM_MAXUSER_ADDRESS
VM_MAX_ADDRESS
VM_MAX_KERNEL_ADDRESS
VM_MIN_KERNEL_ADDRESS

Since i386 needs PDP_SIZE in vmparam.h, I added it there on amd64
too, just to keep things parallel.

Some devices (e.g. ixg in MSI-X mode) don't to have their handlers called
when no interrupt are pending. So add an extra ih_pending field
to struct intrhand, which is incremeted when the handler is not called because
of IPL level and reset to 0 when called. Check this in Xen's resume
assembly to call only handlers that are really pending.

Introduce Xen PVH support in GENERIC.
This is compiled in with
options XENPVHVM
x86 changes:
- add Xen section and xen pvh entry points to locore.S. Set vm_guest
  to VM_GUEST_XENPVH in this entry point.
  Most of the boot procedure (especially page table setup and switch to
  paged mode) is shared with native.
- change some x86_delay() to delay_func(), which points to x86_delay() for
  native/HVM, and xen_delay() for PVH

Xen changes:
- remove Xen bits from init_x86_64_ksyms() and init386_ksyms()
  and move to xen_init_ksyms(), used for both PV and PVH
- set ISA no-legacy-devices property for PVH
- factor out code from Xen's cpu_bootconf() to xen_bootconf()
  in xen_machdep.c
- set up a specific pvh_consinit() which starts with printk()
  (which uses a simple hypercall that is available early) and switch to
  xencons when we can use pmap_kenter_pa().

Get rid of xen-specific ci_x* interrupt handling:
- use the general SIR mechanism, reserving 3 more slots for IPL_VM, IPL_SCHED
  and IPL_HIGH
- remove specific handling from C sources, or change to ipending
- convert IPL number to SIR number in various places
- Remove XUNMASK/XPENDING in assembly or change to IUNMASK/IPENDING
- remove Xen-specific ci_xsources, ci_xmask, ci_xunmask, ci_xpending from
  struct cpu_info
- for now remove a KASSERT that there are no pending interrupts in
  idle_block(). We can get there with some software interrupts pending
  in autoconf XXX needs to be looked at.

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.

Fix a problem with intr_unmask() that can cause a forever-loop:
- When handling the source-is-masked case in the interrupt vector, set the
  interrupt bit in a new ci_imasked field and ensure the bit is cleared
  from ci_ipending.
- In intr_unmask(), transfer the bit from ci_imasked to ci_ipending for
  non-level-sensitive interrupts (the PIC does the work for us in the
  level-sensitive case), and only force pending interrupts to be processed
  in this case.  (In all cases, make sure the now-unmasked bit is cleared
  from ci_imasked.)

Before, the bit was left in ci_ipending so as not to use edge-triggered
interrupts while the source is masked, but Xspllower() relies on the
pending bits getting cleared.

Tested by forcing all wm(4) interrupts on my test system though an
intr_mask() / softint / intr_unmask() cycle and exercising the network
heavily.

Add PCID support in SVS. This avoids TLB flushes during kernel<->user

SVS.

We use two ASIDs, 0 (kern) and 1 (user), and use invpcid to flush pages
in both ASIDs.

The read-only machdep.svs.pcid={0,1} sysctl is added, and indicates whether
SVS+PCID is in use.

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!

More ASLR: randomize the location of the PTE area. The PTE slot is not
created in locore anymore, but a little later; by using the already
entered L4 page, rather than the recursive slot itself (which doesn't
exist yet).

In the prekern we still map the slot - the prekern behaves as an external
locore -, because we need it as part of the randomization/relocation
work. The kernel then removes this slot, and regenerates a randomized
one.

Tested on GENERIC and GENERIC_KASLR, Xen doesn't have it and dom0 still
boots fine.

Unmap the kernel heap from the user page tables (SVS).

This implementation is optimized and organized in such a way that we
don't need to copy the kernel stack to a safe place during user<->kernel
transitions. We create two VAs that point to the same physical page; one
will be mapped in userland and is offset in order to contain only the
trapframe, the other is mapped in the kernel and maps the entire stack.

Remove all references to MDL_USEDFPU and deferred fpu initialisation.
The cost of zeroing the save area on exec is minimal.
This stops the FP registers of a random process being used the first
  time an lwp uses the fpu.
sendsig_siginfo() and get_mcontext() now unconditionally copy the FP
registers.
I'll remove the double-copy for signal handlers soon.
get_mcontext() might have been leaking kernel memory to userspace - and
  may still do so if i386_use_fxsave is false (short copies).

Use the MI "pcu" framework for bookkeeping of npx/fpu states on x86.
This reduces the amount of MD code enormously, and makes it easier
to implement support for newer CPU features which require more fpu
state, or for fpu usage by the kernel.
For access to FPU state across CPUs, an xcall kthread is used now
rather than a dedicated IPI.
No user visible changes intended.

Rename MDP_IRET to MDL_IRET since it is an lwp flag, not a proc one.
Add an MDL_COMPAT32 flag to the lwp's md_flags, set it for 32bit lwps
  and use it to force 'return to user' with iret (as is done when
  MDL_IRET is set).
Split the iret/sysret code paths much later.
Remove all the replicated code for 32bit system calls - which was only
  needed so that iret was always used.
frameasm.h for XEN contains '#define swapgs', while XEN probable never
  needs swapgs, this is likely to be confusing.
Add a SWAPGS which is a nop on XEN and swapgs otherwise.
(I've not yet checked all the swapgs in files that include frameasm.h)
Simple x86 programs still work.
Hijack 6.99.9 kernel bump (needed for compat32 modules)

- Convert x86 MD code, mainly pmap(9) e.g. TLB shootdown code, to use
  kcpuset(9) and thus replace hardcoded CPU bitmasks.  This removes the
  limitation of maximum CPUs.
- Support up to 256 CPUs on amd64 architecture by default.
Bug fixes, improvements, completion of Xen part and testing on 64-core

- pmap_tlb_shootdown: do not overwrite tp_cpumask with pm_cpus, but merge
  like pm_kernel_cpus.  Remove unecessary intersection with kcpuset_running.
  Do not reset tp_userpmap if pmap_kernel().
- Remove pmap_tlb_mailbox_t wrapping, which is pointless after recent changes.
- pmap_tlb_invalidate, pmap_tlb_intr: constify for packet structure.
i686_mtrr_init_first: handle the case when there are no variable-size MTRR
registers available (i686_mtrr_vcnt == 0).

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

- Fix tlbflushg() to behave like tlbflush(), if page global extension (PGE)
  is not (yet) enabled.  This fixes the issue of stale TLB entry, experienced
  early on boot, when PGE is not yet set on primary CPU.
- Rewrite i386/amd64 TLB interrupt handlers in C (only stubs are in assembly),
  which simplifies and unifies (under x86) code, plus fixes few bugs.
- cpu_attach: remove assignment to cpus_running, as primary CPU might not be
  attached first, which causes reset (and thus missed secondary CPUs).

add the guts of TLS support on amd64.  based on joerg's patch,
reworked by me to support 32-bit processes as well.
we now keep %fs and %gs loaded with the user values
while in the kernel, which means we don't need to
reload them when returning to user mode.

On x86, change the bus_space_tag_t to a pointer to a struct
bus_space_tag.  For now, bus_space_tag's only member is
bst_type, the type of space, which is either X86_BUS_SPACE_IO
or X86_BUS_SPACE_MEM.  In the future, new bus_space_tag members
will refer to override-functions installed by a new function,
bus_space_tag_create(9).

Add pointers to constant struct bus_space_tag, x86_bus_space_io and
x86_bus_space_mem.  Use them to replace most uses of X86_BUS_SPACE_IO
and X86_BUS_SPACE_MEM.

Add an x86-specific bus_space_is_equal(9) implementation that compares
the two tags' bst_type.

Remove "struct device" from "struct pic", where it was only real
for ioapics and faked up for others. Add it to "struct ioapic_softc"
for now, until device/softc get split.
This required all typecasts between "struct pic" and "struct ioapic_softc"
to be replaced, I hope I got them all.
functionally tested on i386, compile-tested on xen, untested on amd64

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.

merge yamt-x86pmap branch.

- reduce differences between amd64 and i386.  notably, share pmap.c
  between them.  it makes several i386 pmap improvements available to
  amd64, including tlb shootdown reduction and bug fixes from Stephan Uphoff.
- implement deferred pmap switching for amd64.
- remove LARGEPAGES option.  always use large pages if available.
  also, make it work on amd64.

amd64 (aka x86-64) support for Xen. Based on the OpenBSD port done by
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.

Branch: MAIN

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.
