e3fd0bc1b2 Add SMP/i386 suspend/resume support.
Most part is merged from amd64.

- i386/acpica/acpi_wakecode.S
Replaced with amd64 code (from realmode to paging enabling code).

- i386/acpica/acpi_wakeup.c
Replaced with amd64 code (except for wakeup_pagetables stuff).

- i386/include/pcb.h
- i386/i386/genassym.c
Added PCB new members (CR0, CR2, CR4, DS, ED, FS, SS, GDT, IDT, LDT
and TR) needed for suspend/resume, not for context switch.

- i386/i386/swtch.s
Added suspendctx() and resumectx().
Note that savectx() was not changed and used for suspending (while
amd64 code uses it).
BSP and AP execute the same sequence, suspendctx(), acpi_wakecode()
and resumectx() for suspend/resume (in case of UP system also).

- i386/i386/apic_vector.s
Added cpususpend().

- i386/i386/mp_machdep.c
- i386/include/smp.h
Added cpususpend_handler().

- i386/include/apicvar.h
- kern/subr_smp.c
- sys/smp.h
Added IPI_SUSPEND and suspend_cpus().

- i386/i386/initcpu.c
- i386/i386/machdep.c
- i386/include/md_var.h
- pc98/pc98/machdep.c
Moved initializecpu() declarations to md_var.h.

df2f557df6 Do not double-reference the found vm object in cdev_pager_lookup().
vm_pager_object_lookup() already referenced the object.

Note that there is no in-tree consumers of cdev_pager_lookup(). The
only known user of the function is i915 gem driver, which is not yet
imported. This should make the KPI change minor.

246d751711 Rename pmap_collect() to pmap_pv_reclaim() and rewrite it such that it no
longer uses the active and inactive paging queues.  Instead, the pmap now
maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses
this list to select pv entries for reclamation.

Note: The old pmap_collect() tried to avoid reclaiming mappings for pages
that have either a hold_count or a busy field that is non-zero.  However,
this isn't necessary for correctness, and the locking in pmap_collect() was
insufficient to guarantee that such mappings weren't reclaimed.  The new
pmap_pv_reclaim() doesn't even try.

f4b9a05a90 A problem with the NFSv4 server was reported by Andrew Leonard
to freebsd-fs@, where the setfacl of an NFSv4 acl would fail.
This was caused by the VOP_ACLCHECK() call for ZFS replying
EOPNOTSUPP. After discussion with rwatson@, it was determined
that a call to VOP_ACLCHECK() before doing VOP_SETACL() is not
required. This patch fixes the problem by deleting the
VOP_ACLCHECK() call.

c3a9b90973 Access the device tree blob via copyin/copyout.
The code previously assumed that copyin/copyout did no
address translation and that the device tree blob could
be manipulated in-place (with only a few adjustments for
the ELF loader offset).  This isn't possible on all platforms,
so the revised code uses copyout() to copy the device tree
blob into a heap-allocated buffer and then updates the
device tree with copyout().  This isn't ideal, since it
bloats the loader memory usage, but seems the only feasible
approach (short of rewriting all of the fdt manipulation
routines).

553c9b4d08 Fix a couple of issues that appear to be inherited from the old
8.x code:
- If the lock cannot be acquired immediately unlocks 'bar' vnode
and then locks both vnodes in order.
- wrong vnode type panics from cache_enter_time after calls by
ext2_lookup.

The fix merges the fixes from ufs/ufs_lookup.c.

add some more BAR debugging logic.

* Change the definition of ath_debug and ath_softc.sc_debug  from
  int to uint64_t;
* Change the relevant sysctls;
* Add a new BAR TX debugging field;
* Use this in if_ath_tx.

This has been tested by using the sysctl program, which happily allows
for fields > 32 bits to be configured.

e9a6408e07 Handle non-xretry errors the same as xretry errors for now.
Although I _should_ handle the other errors in various ways (specifically
errors like FILT), treating them as having transmitted successfully
is completely wrong.  Here, they'd be counted as successful and the BAW
would be advanced.. but the RX side wouldn't have received them.

The specific errors I've been seeing here are HAL_TXERR_FILT.

This patch does fix the issue - I've tested it using -i 0.001 pings
(enough to start aggregation) and now the behaviour is correct:

* The RX side never sees a "moved window" error, and
* The TX side sends BARs as needed, with the RX side correctly handling
  them.

b3e9e682cf Implement the DTrace sched provider. This implementation aims to be
compatible with the sched provider implemented by Solaris and its open-
source derivatives.  Full documentation of the sched provider can be found
on Oracle's DTrace wiki pages.

Note that for compatibility with scripts originally written for Solaris,
serveral probes are defined that will never fire.  These probes are defined
to fire when Solaris-specific features perform certain actions.  As these
features are not present in FreeBSD, the probes can never fire.

Also, I have added a two probes that are not defined in Solaris, lend-pri
and load-change.  These probes have been added to make it possible to
collect schedgraph data with DTrace.

Finally, a few probes are defined in Solaris to take a cpuinfo_t *
argument.  As it was not immediately clear to me how to translate that to
FreeBSD, currently those probes are passed NULL in place of a cpuinfo_t *.

2108487ead Fix two cases in the new NFS server where a tsleep() is
used, when the code should actually protect the tested
variable with a mutex. Since the tsleep()s had a 10sec
timeout, the race would have only delayed the allocation
of a new clientid for a client. The sleeps will also
rarely occur, since having a callback in progress when
a client acquires a new clientid, is unlikely.

a fresh clientid is being acquired by a client is unlikely.

6130ff50fb Setup the CPU port and broadcast map on the AR7240, rather than
depending upon the bootloader initialising it.

The aim is to eventually support a full switch set and reinitialisation
rather than relying on a consistent bootloader setup.

Remove the port flood config from arswitch.c, it's not yet used and
it's totally incorrect.

Whilst I'm here, also add in a comment describing why the full switch

b7ac5a8571 Add new pager type, OBJT_MGTDEVICE. It provides the device pager
which carries fictitous managed pages. In particular, the consumers of
the new object type can remove all mappings of the device page with
pmap_remove_all().

The range of physical addresses used for fake page allocation shall be
registered with vm_phys_fictitious_reg_range() interface to allow the
PHYS_TO_VM_PAGE() to work in pmap.

Most likely, only i386 and amd64 pmaps can handle fictitious managed
pages right now.

b6de32bd9b Add a facility to register a range of physical addresses to be used

after consumer stopped using it.

De-inline the PHYS_TO_VM_PAGE() since it now carries code to iterate
over registered ranges.

A hash container might be developed instead of range registration
interface, and fake pages could be put automatically into the hash,
were PHYS_TO_VM_PAGE() could look them up later. This should be
considered before the MFC of the commit is done.
